This is an excellent tug for assistance in offshore conditions at LNG and oil terminals, but also for loading stations for the mining industry in open sea, such as those in Northern Australia. 14 15 A MILESTONE IN SHIPHANDLING TUG DESIGN a world standard The Damen Azimuth Stern Drive Tug 3212 has decades of experience and knowledge embodied in it, which has allowed Damen to create a truly innovative vessel and we believe it to be one that is a milestone in tug design. This new tug type has been designed to be a world standard, complying with all of the major Classification Societies’ requirements and the latest international environmental regulations. We know what a tug has to be able to do to operate efficiently in waves. Projects today - going further offshore in more challenging, open waters – needed a new tug type. Damen has answered this demand with the ASD Tug 3212. Introducing a new ASD Tug generation 16 This powerful shiphandling tug has been purposely designed for worldwide use and to operate in wave heights of up to 3 m in exposed locations. She has excellent seakeeping behaviour, superb manoeuvrability and towing characteristics and a state-of-the-art design incorporating the latest hull and skeg design and the most recent developments in fender, fairlead and winch design. The ASD Tug 3212 can tow and assist over the fore deck but it will also be able to tow over the aft deck, making it ideal for salvage operations. 17 conTenTs Damen asd tug 3212 Introduction16 Our history in Tug building 20 Timeline 21 PRODUCT range 22 From sketch to ship Research & development 24 26 Our standards The damen asd tug 3212 in detail 30 32 The foredeck 34 The aft deck The engine room 40 42 The under water ship 50 The wheelhouse 58 History 20 The engine 44 ASD Tugs Stan Tugs SAFETUG TUGSIM Stability Principal dimensions First fully classified winch FMEA Towing bitt & fairlead Sausage fendering First fully classified winch 36 interior 64 The engine Damen Hybrid E3 Modular pump systems Closed cooling system Ventilation systems Corrosion prevention Rudder Propellers Unique hull form Damen MEGA Systen 22 23 27 28 29 32 36 37 38 39 44 45 45 46 48 49 52 54 55 62 Interior64 Ergonomics & comfort 68 Specifications70 Damen Services 76 colophon79 18 19 Decades of experience in ASD tug building Our history in tug building Damen Shipyards has built more than 2,000 shiphandling tugs and delivered them to more than 125 countries over the last four decades.

ASD TUG 2810 STAN TUG 4511 23 From sketch to ship Built by passion Built for performance Naturally full 3D engineering was the key in leading to this superb design, with attention to the very smallest detail. 24 Needless to say, this tug’s product development was in the hands of dedicated tug teams, which have often worked together for more than 25 years. This wealth of knowledge and experience is all to the benefit of our customers. To say these employees pretty much live, eat and breathe tugs is no exaggeration. Their enthusiasm and knowledge is undoubtedly responsible for the success of the Damen ASD Tug 3212. 25 Research & development Extensive testing As well as the knowledge gained from building hundreds of ASD Tugs, the Damen ASD Tug 3212 has undergone rigorous testing over the last few years, both at Damen’s own Research & Development Department and at the renowned Dutch maritime institution, the Maritime Research Institute Netherlands (MARIN). The ASD Tug 3212 has a completely revised hull form when compared to previous vessels as a result of these tests. The vessel has a higher bow with a more flared shape and a revolutionary new hull form with a more pronounced “V shape” in the foreship, more slender lines in the bow, as well as bilge keels. A relatively low wheelhouse guarantees low accelerations for improved crew comfort and increased stability. The shape of the hull guarantees optimal manoeuvrability. The design has also been based on measurements taken on more than 350 ASD Tugs already in operation. Damen uses Dieudonné tests to take measurements on all of its ASD tugs. Damen actively participated in the Joint Industry Project SAFETUG, which has examined tug escorting in exposed sea conditions in detail. The project discovered that high peak loads in the towline are a limiting factor in the operation. Staying connected to the assisted ship is vital for the tug operation and very high peak loads can lead to the towline breaking. SAFETUG II was successfully completed in 2011 and many of its findings have been incorporated into the new design. Safetug With the knowledge of SAFETUG II and the challenge to prove the pioneering new ASD Tug 3212 hull shape, the new design underwent rigorous model tests in the towing tank at MARIN, including escorting and seakeeping tests in waves. An experienced Smit tug Captain carried out the tests, where the model of the ASD Tug 3212 was being actively controlled in 3 m waves with a towing wire attached. The Render / Recovery winch was also used to ensure power in the towing line was as stable as possible. This gave a thorough analysis of the dynamic loads on the towline and these tests exactly mirrored real conditions. 26 27 Damen’s in-house developed simulation program a low centre of gravity and an extremely high GM value Tugsim Stability To predict the escort capabilities of ASD tugs, Damen Research has developed the computer program ‘TugSim’ in cooperation with Delft University of Technology and MARIN. The extremely powerful 360-degree, rotating rudder propellers of an 85 tons ASD Tug demand superb stability. Damen tugs are continuously evaluated and improved upon. We are always looking to answer our customer’s needs and the ASD Tug 3212 is no exception. Naturally crew comfort and safety are always foremost in Damen’s mind and the ASD Tug 3212 has improved workability, largely due to the new hull. The dimensions of the unique shape of the skeg and bilge keels were designed by Damen Research together with MARIN by using TugSim calculations. Stability was a key focus of the design, particularly given the challenges this vessel will face in open waters. Improved stability has been achieved by a wide beam, more slender waterline, large freeboard, higher bow, coupled with a relatively low wheelhouse. Overall, the new tug has a low centre of gravity and an extremely high GM value of 2 m. For extra safety, we have made sure that the distance between the towing point and the thruster is also as low as possible. The TugSim program makes it possible to calculate escort forces on the towing line and the performance of the tug. TugSim can be used as a design tool, therefore Damen could optimise the design of the ASD Tug 3212 at an early stage. TugSim uses fundamental hydrodynamic theory concerning hull shape, skeg, bilge keels and thruster forces. In combination with information on the propulsion installation and the location of the towing point, this quasistatic approach gives the maximum breaking and steering force in each direction. A capability plot can then be made for every escorting speed. Escort tests at a speed of 10 knots in waves up to 3 m were carried out during the model tests. Dynamic forces of 2.5 x the tractive force occurred in the towing lines. The maximum loads on the fairlead and the bitt can increase up to a maximum of 200 tons during escorting and the line can turn at a maximum angle of 120 degrees. Dieudonné Manoeuvrability of the ASD Tug 3212 is of the utmost importance and to this end a lot of effort was spent on optimising the hull, skeg and bilge keels during development. To assess the manoeuvrability of the ship, Dieudonné trials were conducted at MARIN whereby the continuous rate of turn at a certain thruster angle setting was recorded while the vessel was in deep, open water. 28 Repeating this for a wide range of thruster angles determines the inherent dynamic stability of the tug sailing ahead and astern. Damen Research then uses this data to validate its predictions and model tests and for making further improvements, if needed. 29 the key to your success our standards Standardisation and the continuous development of all of our tugs leads to high quality in every detail, giving rise to tugs that are entirely fit for purpose. The new ASD Tug 3212 benefits from Damen’s standardisation strategy. Because our vessels are sold all over the world, Damen always looks to build a Damen standard tug that is just as fit for purpose in Russia as it is in Australia and the Arabian Gulf. This means many of the components in the new tug are built to proven designs. For instance, our Damen standard cooling system is able to operate to its optimum in minus 30 degrees in St.Petersburg or equally, in soaring high temperatures in the summer months off the coast of Northern Australia and the Arabic Gulf in seawater temperatures of 35 degrees. The well-known Damen philosophy of standardisation is certainly evident in this new tug type. We offer proven design, proven quality, proven reliability and this all contributes to lowering the Total Cost of Ownership. She is a heavy built vessel, with rigid foundations, extra plate thickness, extra brackets and extra fendering. This is the Damen standard and one that is above and beyond Class requirements. Our standard ASD Tug 3212 is provided with an Environmental Class notation. Therefore, a bilge water cleaner and sewage plant have been installed and there are no ballast tanks. Standard designs can always be equipped with various options to suit your specific job and/or regulations. Damen demands the very best quality to ensure the best performance from its vessels. Customer feedback is continually fed into our standard designs as we continue to strive for improvement. Not only are our vessels built to the Damen standard, so too are our optionals and these are all kept on stock for customers’ convenience. One standard grease nipple type for easy maintenance.

Bow & hull form A higher bow with a more flared shape and a revolutionary new hull form with a more pronounced “V shape” in the foreship, more slender lines in the bow, as well as bilge keels. 33 The foredeck Optimum use of space a safe working environment for the crew The foredeck has a completely flush design, optimised for various towing modes giving this multipurpose tug optimal performance. An ergonomic design has been incorporated into the new ASD Tug 3212 with good accessibility to winches, bollards and the fairleads. Compact winch Fairleads Spraying nozzles Spacious deck The first fully classified Render / Recovery winch is equipped with two incredibly strong Hägglunds CB840 motors. Class-approved, double-pole towing bitt, with cast, certified stainless steel fairlead, for smooth rope handling. Also the top of the bulwark is stainless steel. Three spraying nozzles are installed on the towing bitt for greasing the ship’s hull. Again, another innovation and included in the Damen ASD Tug 3212 as standard. A proven deck layout, ergonomically designed with good accessibility to winches, bollards and the fairleads has been incorporated in the new ASD Tug 3212. The motors are directly on the main shaft so no gearbox is required, giving even more deck space. 34 This spacious deck – free of obstacles – facilitates safe shiphandling in harbours, estuaries and at offshore terminals. 35 FIRST FULLY CLASSIFIED WINCH The winch has been made for successful operations in waves of up to 3 m high over a 6 second wave period! a maximUm bollarD pUll of 85 Tons Identify functions Check and action Potential failure FMEA Risk priority number RPN = SEV x OCC x DET The entire Render / Recovery winch system must be fully tuned and tested according to the highest offshore standards. FMEA procedures are part of the high Damen quality standards. Detection number (DET) We know we are in a different world these days, where the ability to provide assistance in open water is vital. This exceptional Render/Recovery winch was developed together with another Damen Shipyards Group member, Maaskant Shipyards Stellendam, which has many years of experience developing winches for the fishing industry. 36 The fully automatic winch is also the first in the market that has been fully classified by Lloyd’s Register. This winch is now proven for the challenging conditions off Northern Australia and for future offshore projects in open water. The hydraulically powered, double drum winch (with one running and one on standby) has a maximum brake holding load of a massive 200 tons, a recovery capacity of 60 tons at 50m/min and a rendering capacity of 100 tons at 100m/min. The winch has a very tough, strong and simple design equipped with two Hägglunds CB840 motors. This is very tough equipment even used in the mining industry. The motors are directly on the main shaft so no gearbox is required. Severity number (SEV) Probability number (OCC) In line with Damen’s quality standards, stainless steel brake drums are provided. Stainless steel is used to prevent corrosion so the drums can last for a lifetime. And there are double drums, so always a spare line! The fully automatic winch is also the first in the market that has been fully classified by Lloyd’s Register. This winch is now proven for the challenging conditions off Northern Australia and for future offshore projects in open water. 37 Sausage Fendering Working at sea with a pushing force of 85 tons makes it a great challenge to design fendering that will not damage the ship’s skin. The high waves make it necessary for a tremendous amount of energy to be absorbed. An entirely new design for a 1 m double-sausage fendering has been developed for improved energy absorption. The fender has been designed using Finite Element Analysis and full-scale validation tests with loads of up to a massive 640 tons. Again our specialists in R&D spent a great deal of effort doing the calculations to produce the perfect fender. One engineer even spent a year on this subject alone. Ultimately, the fendering has improved energy absorption handling huge dynamic forces. Tests also found that when pushing at maximum bollard pull, the contact pressure should not exceed 20 t/m2. Towing Bitt & Fairlead Given the huge forces in the towing lines exerted during escort operations – up to a maximum of 200 tons – and the fact that the towing line can bend at wide angles, between 0 and 120 degrees to the centreline, Damen Research has especially focused on the design of the towing bitt and the fairlead. 38 Again, this towing bitt is a unique design and represents a new generation. Damen recommends the use of 60 mm Lankoforce ropes and to avoid rope damage a special cast, stainless steel bitt has been developed for both its strength and anti-corrosion properties. The stainless steel castings are fully integrated in a welded bitt with piping with a diameter of 500 mm, creating a hawser friendly design that guarantees the maximum durability for the towing lines. Everything is fully rounded to make the bitt as smooth as possible to prevent wear-and-tear of the towline. This all makes for smooth handling of the delicate and expensive towing ropes. New generation Towing Bitt Damen has especially focused on the design of the towing bitt because of the tremendous forces in the towing lines. Again, this unique design represents a new generation. To avoid rope damage a special cast, 50 mm thick, stainless steel bitt has been developed for both its strength and anti-corrosion properties. Everything is rounded to make the bitt as smooth as possible to prevent wear-and-tear of the towline. 39 The aft deck for multipurpose activities The aft deck has a completely flush design, optimised for various towing modes giving this multipurpose tug optimal performance, whether the tug is involved in a salvage, oil recovery operation or in buoy handling. Engine room hatches Quality Quality surfaces & painting Spacious aft deck The aft deck has flush engine room hatches, with the main engines and all of the engine room equipment installed via these hatches. To ensure top Damen quality, after all of the steelwork of the hull is ready, the tug is completely painted, so consequently no steelwork or welding is done after the paint system is applied. The bulwark construction is rounded, making a better surface for painting. Painting is of a very high standard being the two part, heavy duty Epoxy paint systems, applied by Damen under cover in strictly controlled conditions. This spacious deck – free of obstacles – facilitates safe ship handling in harbours, estuaries and at offshore terminals. This new tug is truly multipurpose. The engine room hatches are also for the easy and quick installation of optional FiFi sets and hydraulic sets after the Damen Standard vessel is ready. We have anticipated the future needs of our clients so everything is ready should they want to upgrade at a later date. 40 Grinding and welding after painting is avoided. This all leads to better rope guidance and less wear-and-tear. A ventilated storage area is provided on SB & PS in the aft bulwark with watertight hatches. Containers, skimmers, booms, shackles and other equipment can easily be stored on deck and there is still plenty of room. 41 The engine room The heart of the vessel Safe working conditions, optimal accessibility and easy maintenance were all crucial elements when Damen considered the engine room design. Damen’s ASD Tug 3212 has a spacious engine room to facilitate easy maintenance. Engines Easy access and easy maintenance Piping systems The main engines are Caterpillar 3516C HD+ TA/D, giving a maximum of 1800 RPM and very quick acceleration. Summed up: much more torque with lower RPM. The engine room has been designed for optimal accessibility for the customer’s convenience. All piping systems are fitted carefully to prevent vibrations. They are all colour coded and flow directions are indicated. Pipe sections are flanged in manageable lengths – again for ease of maintenance. And the engine room is fully equipped with stores, a workbench, a grinding and drilling machine, as well as lockers. Parts are also provided by Damen. Every detail has been considered. For example, in the engine room floor there are easily accessible entry points to make it simple to inspect the stainer baskets of the galvanised bilge system. 42 Safety first “One hand for yourself and one for the ship!” Hand grips and handrails are provided throughout for maximum safety. 43 Dramatic cuts in fuel consumption and emissions possible damen hybrid The Hybrid option Damen is well aware of the need to make fuel savings as prices soar and to cut back on emissions. Consequently, we are building a hybrid option of the ASD Tug 3212, which will be available from stock. The tug can be delivered with a combined Hybrid generator/firefighting diesel. The generator set will supply the power to two electric motors in the drive shafts. This allows the tug to sail at a speed of 7 knots on electric power in transit modes. In this way it is possible to reduce emissions and fuel consumption by more than 25 %. Summed up: much more torque with lower RPM. E3 Damen has introduced its own quality brand – the E3 hallmark – a move that is unique in the shipbuilding industry. Damen continually works to improve its vessels and aims to build ships according to the Damen “E3” principles: Environmentally friendly, Efficient in operation and Economically viable. These take into account the needs of the planet, the people operating the ship and the owner’s need to make a profit. The engine The standard ASD Tug 3212 is fitted with economical Caterpillar 3516C HD+ TA/D main engines giving a maximum of 1800 RPM and very quick acceleration. Environmentally friendly Efficient in operation Economically viable The new Damen ASD Tug 3212 is designed to ensure durability and for this reason main engines with Tier II have been installed and, with an eye to the future, Tier III systems are also being considered. And to ensure low vibration and noise levels the engines are flexibly mounted, isolating them from the steel. Main engines and auxiliary engines have 45 dBA exhaust silencers to obtain low noise levels and are fitted with spark arrestors which are suitable for LNG terminals. Bunkering in just two hours! Damen is always keen to have a happy crew aboard its ships and we have gone beyond the requirements of Class and introduced a 2-inch diameter filling pipe to speed bunkering up. We know ease of operation and efficiency is vital to our customers. 100 80 60 40 Propulsion installation in the engine room is in accordance with Lloyd Register's regulations for Unmanned Engine Rooms, hence permanent attendance is not required. 20 0 NOX PM HC ASD Tug Standard 44 CO Fuel CO2 SOx ASD Tug Hybrid 45 Modular pump systems In line with Damen’s standardisation policy, the systems are provided in standard modules, including the pump systems and valve blocks for easy operations. Again for ease of operation and maintenance everything is marked, labelled, colour-coded and flows are indicated. For the maximum safety of the crew, full control of the engine room is possible from the main deck when the tug is carrying out a towing operation. The crew can monitor the alarms, analyse the problem and then take action. In a further anti-corrosion measure, a dedicated ventilation system with mist eliminators is provided so sea wash and mist cannot enter the engine room. All piping systems have heavy, thick walls, which is above and beyond Class requirements. 46 future ready A bolted engine room hatch facilitates simple removal and engine installation and because we have anticipated possible future FiFi set installations, (Damen has a full range of optionals), all the pipes and FiFi foundations have already been provided. 47 Ventilation systems The wheelhouse, accommodation, engine room, rudder propeller room and stores have forced fresh air ventilation systems. The velocity of air does not exceed Damen standards and sound absorbent material is fitted in the ducting, all of which reduces the noise levels for extra comfort. Air intakes for the engine room and accommodation are fitted with cloth filters to avoid dust. In the accommodation an AC system is fitted for cooling and heating and the fresh air outlets can be controlled locally. The wheelhouse has a separate AC system with an automatic room thermostat. The AC system is cooled by a closed, fresh water cooling system (there is no seawater on board). All equipment, such as cooling compressors, condensers and air handling units have maintenance-friendly installation, so changing the filters in the air handling unit in the accommodation could not be easier. It is only a 5 minute job! Closed cooling systems No pollution, no corrosion and no freezing. Damen uses closed cooling water systems, which are designed for 35 degrees seawater temperatures for diesel engines and AC systems. This is not the cheapest solution but Damen wants to avoid any risk of pollution or corrosion so these cooling systems are included as standard. This level of quality in turn, makes it maintenance friendly. Damen is very experienced with closed cooling systems. Durable, box cooler-type heat exchangers, with increased pipe thickness, are fitted in sea chests. To give optimal performance and maximum lifetime, these have been developed in close cooperation with the supplier and Delft University. The Impressed Current Anti-Fouling (ICAF) system fitted inside the cooler chests means that there is no marine growth or fouling. 48 49 The under water ship Box cooler gratings Gratings for the box cooler chest are hinged for easy inspection and maintenence. Propeller nozzles The Damen Standard ASD Tug Series are fitted with propeller nozzles with stainless steel inner rings to increase their lifetime. Propellers SB and PS propellers have opposite inward turning direction of rotation to create maximum performance. First class marine type All machinery in the engine room is of first class marine type and the installation is laid out for easy watch-keeping, servicing and maintenance. The main engines can be started from the engine room, as well as from the bridge. 50 51 Against the biggest enemy Corrosion prevention Corrosion is the vessel’s enemy. Damen has done its utmost to think about any possible weak points where corrosion could start and taken steps to eliminate them. ANTI-CORROSION SOLUTIONS and PAINTINg The Damen ASD Tug 3212 incorporates the most state-of-the-art solutions for corrosion prevention. All steel parts are well rounded, there are no sharp corners and welding is done without overlap or undercutting. All areas are closed and easily accessible for preservation and maintenance. Stainless steel has been used throughout on all moving parts, again, to extend their lifetime and prevent corrosion. Parts outside on the superstructure and on deck such as hinges, toggles, floodlights, bolts, nuts, nameplates, gratings, towline fairleads, window frames and filling pipes are all stainless steel and all railings and stairs are made from galvanised steel. The decks are also smooth and bevelled, making them easy to paint and to clean. The main deck is entirely flush, with the foundations for the winches and other equipment below deck.

Additionally, it has a higher bow with a more flared and slender shape, resulting in a dry fore deck during shiphandling and escort operations. To improve the ship’s stability the sides slope outwards and are provided with rolling keels and sloping sides. All of these factors plus heavy sausage fenders result in a drier ship and consequently, a safer ship. Rudder propellers The ASD Tug 3212 incorporates new Rolls-Royce rudder propellers, type “US 255 P30 CP Special”, with a 2800 mm diameter and special TK-type high performance nozzles, with two full 360-degree rotating controllable pitch propellers in the aft ship. 54 Better seakeeping characteristics are achieved through a more slender waterline in combination with a relatively low wheelhouse, slope frames and bilge keels. These measures guarantee low accelerations for improved crew comfort and better stability. The hull is very rigidly built, with top quality welding. We have taken care that everything is rounded for both optimal performance and to limit corrosion. There are no undercuts, no sharp corners - everything is clean and maintenance friendly. Perfect welding with no undercuts, means that corrosion is avoided. Damen designed a special round bilge hull shape rather than the more common chine hull because this gives the vessel better performance. Damen continually seeks perfection. The hull structure, steelwork fittings and pipe systems are all drawn and designed to the smallest detail in 3D. This guarantees that the hull is 100% outfitted with small parts before sandblasting and Epoxy painting. The hot-dip galvanised anchors are recessed in pockets, giving a completely flush hull. After many years of research into how to achieve optimal performance, Damen also mounts the rudder propellers 7 degrees from the base line. In contrast to most shipbuilders, Damen fits the rudder propellers with stainless steel inner rings. Our “standard” is always of the utmost quality. Customers don’t have to worry about renewing the inner rings because we design for the lifetime of the vessel. 55 You are in control 56 57 the wheelhouse 58 A compact wheelhouse gives the Captain an excellent, all round, 360-degree view. The tumblehome is guaranteed at 40 degrees and this is combined with a foldable, remote controlled mast. Direct accessibility Cleaning system Large windows Floodlights Both the fore and aft deck are directly accessible by stairs from the wheelhouse. SB to the fore deck, PS to the aft deck. A fresh water spraying system is provided for cleaning the vessel's windows. To give the best visibility possible large, tinted windows are provided, giving excellent sight lines. Sky windows give an optimal view on vessels being assisted. Powerful floodlights are provided in the fore and aft deck. On the aft deck two 500 watt lights are installed and on the fore deck, four 500 watt lights. 59 the wheelhouse everything at your fingertips Damen has designed a very modern, compact deckhouse with good all round visibility and a user-friendly layout, with excellent lines of sight from the wheelhouse on the fore deck, shoulders and assisted vessels. The Captain has everything under full control from the wheelhouse including the propulsion units and winches from the steering position – with full hand, foot and knee control. Propulsion control is combined into one “joystick”. Everything has been ergonomically designed, with easy-to-use operating consoles and Damen has spent a great deal of effort in developing a new wheelhouse Local Operator Panel (LOP) with nautical data, main engine, winch and auxiliary control, alarms and fire detection. All of this data is available in the engine room, on main deck and in the wheelhouse. The tumblehome is up to 40 degrees with the wheelhouse leaning inward, and this is combined with a foldable, remote controlled mast, making it ideal when working under the flare of a vessel. The superstructure and bulwarks have sufficient tumblehome to avoid collision damage. 60 61 New damen mega system The ASD Tug 3212 includes a completely new Praxis MEGA operating and control system with one multifunctional touch screen - with a day and night screen - located on the main deck, in the wheelhouse and engine control room. This conning system is part of the Alarm & Monitoring system and allows the crew to control and monitor the main propulsion, auxiliary, electric systems and tank capacities, as well as all the lighting and ventilation at all three locations. And for the maximum safety of the crew, this system facilitates full control of the engine room from the main deck when the tug is carrying out a towing operation. In case of emergency if the normal system fails, the engine control, the steering system and all vital systems can be operated by means of emergency control systems. Steering can be done by non-follow-up emergency steering (24V) operated by means of pushbuttons in the wheelhouse dashboards. 62 63 interior Cabins Larger, very comfortable, air-conditioned cabins, with doublewalled panelling are provided, with all of the cabins above the waterline to comply with the latest regulations. Materials IT Durable and easy to maintain waterproof, hard plastic coated marine plywood has been used. The accommodation has modern furnishings in Damen Standard colours. Information screens, televisions, radios and computer systems are provided in the messrooms and the cabins. A computer network with high quality, ethernet technology, with external GSM antenna is also installed. The helmsman’s seat has electric controls and is covered with leather. Sofas and chairs in the cabins and messroom have heavy-duty, artificial leather. Curtains are fitted in the cabins for windows and berths. In the galley, messroom and cabins storage space is provided by drawers and lockers. Extra linen, dry food, freezer and general storage space are also provided. 64 Space Officers have a 7.5 sq m cabin, with a standing height of 2.2 m and extra large lockers are provided. Berths are 2200 x 900 mm with box spring mattresses. Everything has been considered from an ergonomic point of view. The accommodation is acoustically insulated and finished in modern colours with durable linings. 65 66 67 Ergonomics & comfort The Damen ASD Tug 3212, which has a capacity for a maximum crew of 10, is built to comply with all of the very latest IMO and MLC 2006 crew accommodation and comfort regulations. This includes more spacious cabins, more comfort, better sanitary facilities and extensive stores. designed for a pleasant working environment The heavy, well-built steel hull has a very low vibration level at maximum speed which, together with sound insulation measures, results in a low noise level. During trials the noise levels in the cabins were extremely low; 53 dBA was the lowest level measured in the cabins below decks and the lowest ever measured on a Damen ASD Tug! Noise and vibrations are also kept to a minimum due to flexibly mounted main engines and flexible drive couplings. The accommodation and wheelhouse have a floating floor to keep noise levels within 55 dBA and vibration levels to a minimum. 55 dBA = Cabin noise levels of just 53 dBA – lower than those of a coffee machine! If the vessel is being operated for a 12-hour stretch, it has to be comfortable for the crew, which in turn makes it much safer. For instance, Damen’s standard ASD Tug 3212 includes 25 cm high box spring mattresses for extra comfort. We want to make sure we have created the best working and living environment for the crew. The console can be opened for maintenance and inspection. 68 69 Specifications 70 71 Main particulars S All pipes manageable for easy refitting S Round bilge hull S Propulsion system and electrical equipment is designed for outside air temperature of max. 45°C S Pipelines with a minimum number of bends S Five watertight compartments S Electrical, dual speed parallel window wipers on each forward side S Lloyd's Register 100 A1 Escort Tug () LMC UMS EP S Bilge and internal FiFi seawater piping hot-dip galvanised S Rudder propeller compartment with double bottom tanks S Electrical, dual speed parallel window wipers on each front window S Lloyds Register 100 A1 Escort Tug () LMC UMS EP Fire Fighting Ship 1 Ø Piping and valves marked with colour codes S Engine room with double bottom tanks S Electrical, dual speed parallel window wipers on each aft window S Successful model tests at MARIN S Two general service pumps S On the outside, the hull is continuously welded S A window wash nozzle for each window wiper S Two complete sets of plans and documents S Bilge water separator S Distortion and unevenness from welding will be faired S Docking plugs stainless steel / bronze for all tanks S International tonnage certificate S Deck connections for sludge, dirty oil and bilge water S All tanks are provided with two bolted manhole covers S Galvanised steel handrails along the deckhouse S Loadline certificate S Fire fighting pumps S Fuel oil tanks are separated from the hull S Aluminium railing near the compass S International oil pollution prevention certificate S Emergency fire fighting pump S Two steel, fresh water double bottom tanks S Safety railing in the propulsion rooms S International sewage pollution prevention certificate S Fuel transfer pump S Sewage tank with discharge point on deck S Protection covers for rotating parts S International air pollution prevention certificate S Dynamic fuel oil purifier S Two clean lubrication oil tanks S Two cylindrical bow fenders Ø 1000 mm S Anchor and cable certificates S Fuel header pump S One dirty lubrication oil tank S A continuous D-type fender, size 300 x 300 mm S GMDSS A1 certificate S Duplex fuel water separator for each engine S Sludge tank S Cylindrical fenders 600 mm on the transom corners S Asbestos free certificate S Duplex fuel oil filters in each engine S Hydraulic oil tank S Lugs are fitted for heavy fender tyres S Fresh water certificate S Cooling water system for engines is of the boxcooling type S Bilge water tank with discharge point on deck S Double bollards on the fore ship S GMDSS area A2 Ø Boxcoolers for a seawater temperature of 35°C S Foam tank Ø Single bollards at midship S GMDSS area A3 Ø Fresh water window spray system S Dispersant tank Ø Double bollards on the aft ship S MED approval S A tap is fitted both aft deck and bridge deck S Sea chests with hinged gratings S SWL welded on all bollards S Fresh water heater S Anchor stowed in anchor pockets, flush with the hull S Aft towing bitt with cast, certified steel fairlead S Sewage pump S Bulwark has a height of 1.10 m S Flush gobeye on the aft deck S Sewage treatment plant S Deck lockers integrated in the aft bulwark S Local tow wire protection rails S Propulsion and steering system 72 Hull and superstructure Primary ship systems Propulsion system and electrical equipment is designed for seawater temperatures of max. 35°C IMO Tier II and EPA Tier II compliant marine diesel engines S Central filling and deaeration system S Stainless steel plate fitted on top of the fore bulwark S Fixed navigation mast S SB and PS propellers opposite inward direction of rotation to create maximum performance S All sounding and filling pipes are stainless steel and have screw caps S Skeg with 20 mm bottom plate S Foldable navigation mast Ø Start and stop of main auxiliary engines in the engine room S Electrically driven lubrication oil fill pump S Bilge keels improve operability in exposed waters S Mast with safety system for safe access S Main engines started from the bridge S Lubrication oil fill pump manual S Towline guard posts aft bulwark S Stainless steel outside nameplates S Auxiliary sets can start from switchboard room S Sludge pump S Crankcase deaeration piping via funnels S Loaded waterline (paint line) marked by beat welds S Resiliently mounted diesel engines S Pre-lubrication oil pump on each main engine S All hinges are adjustable and greased by standard grease nipples S Boundaries of tanks and watertight bulkheads on hull and on deck are marked by beat welds S Marine diesel engines are electrically started S Duplex lubrication oil filters in each engine S One flush engineers’ workshop hatch S Hull plates are cleaned by blast cleaning grade SA 2 1/2 S Marine diesel engines are fresh water cooled by means of boxcoolers S Forced ventilation -
