Shark net protection
Dear sir,
We would like to inform you about our products which could improve profitability and reliability of your institution
following the recent shark attacks.
We are aware of the major problems currently occurred in Sharm el Sheikh after several shark attacks on tourists.
Our company offers a unique means of protection, reliable and reasonable for entertainment facilities of your
beach while ensuring the preservation of the corals.
We realize the pose off a safety net in the sea to prevent any approach from the shark. The net is very durable
and resistant to decay, it is used in mountain environments and perilous order to retain and prevent the falling
rocks, it is resistant to several tons of pressure. The synthetic mesh of the net ensures passage of all fish species except large predators .
The installation of this net can be realized directly on the existing floating dock or via a cable line with buoys
making it impassable for all marine predators such as sharks or other Longimanus.
Bay Sharm has the advantage of benefiting from a shallow beach, which will be advantageous for technical
installation and reduce costs.
For more technical details concerning the installation and specifications of our product feel free to contact us.
(Securing an area for swimmers could easily spread across fifty yards from shore, see! The idea is to allow
more access to smaller fish that pass easily through the cracks.)
Regular inspection of the net remains necessary, to prevent possible damage by a boat or swimmers.
An annual inspection will be supported by us through previous agreements. The presence of rays
and fish of big sizes will be rejected prior to installation of the net. If there are still some, they will be
transferred beyond the net.
The system has no consequence on the marine environment while giving full satisfaction and security
for guests. A panel will clearly indicate to customers that they are in protected areas.

Sincerely,
Eeckhout Yves
General Manager

Egypt fears shark attacks
will dent tourism industry
SHARM EL-SHEIKH, Egypt - Egyptian authorities
were Thursday racing to contain potential fallout
from a spate of mysterious shark attacks that has
threatened tourism in one of the country's main Red
Sea resorts.
The attacks, which took place over a week culminating in a German tourist's death on Sunday days
after three Russian holidaymakers and a Ukrainian were mauled, have mystified experts.
A ban on swimming and snorkelling slapped after Sunday's deadly attack in Sharm el-Sheikh has been indefinitely extended, South Sinai Governor Mohammed Shosha said on Sunday.
The ban -- which affects an eight-kilometre (five-mile) stretch of beach including popular Naama Bay -- has
triggered fears among industry professionals that long-term restrictions could dent the vital tourism industrie
The government is keen to protect the tourism industry, a main source of foreign currency for Egypt, with revenues totalling 10.76 billion dollars last year despite a 2.1 percent decline in receipts in the face of the recession
hitting its main European markets.
Tourism accounts for about 11 percent of the country's gross domestic product and provides employment for
10-12 percent of the country workforce.
Around 12.5 million tourists visited the country in 2009, including more than two million from Russia.
Al-Ahram online, the website of the government daily Al-Ahram, on Thursday quoted a Russian tourism
official in Moscow as saying Russian tourism to Egypt has dropped 20 percent because of the shark attacks.
"The sooner the Egyptian side settles the problem and provides security at its beaches, the less tourists
will refrain from trips to Egypt," Al-Ahram online quoted Nadezhda Nazina, Russian deputy minister of
sports and tourism, as saying.
Tourism Minister Zoheir Garana said in February that the government hoped to see arrivals rise to 14 million
this year, bringing in revenues of 11.5 billion dollars.
The authorities are taking no chances after Sunday's attack, which occurred just metres (yards) offfshore before
the eyes of horrified holidaymakers.
They had prematurely opened the beaches after attacks on November 30 and December 1 wounded three
Russians snorkellers and a Ukrainian, whom Shosha confirmed was bitten by a shark -- dismissing earlier reports he had injured himself on a coral reef.

Elena Ribac, manager of a Moldovan tourism agency that organises trips to Sharm el-Sheikh, said her company
had noticed a drop in reservations.
"I think no one wants to be eaten by a shark. We are not selling as much as before," the attacks, she said.
Foreign and Egyptian experts have met witnesses to the attacks as they try to understand what brought sharks
so close to a so-called safe area near the shore.
Experts have suggested that sharks have been lured to the shore by illegal feeding, while others blame their
behaviour on changes in the ecosystem.
Shosha said the beaches would reopen either when the sharks have been hunted down or when protections
are put in place for swimmers.
"The criteria (for reopening the beaches) consists of
two parts. The experts have to tell us how to deal
with the shark and capture them. The other thing is
to take precautions, such as placing nets in front of
beaches," he said.
"We cannot forever ban swimming, we will put nets
in front of beaches for whoever wants to swim," he
said.
One shark which is believed to have attacked two
swimmers last week was caught on Friday but the
killer one responsible for the death of the German
woman is still at large, officials say.
The possible solution for the security
The placement floating systems provides and ensures all the essential safety precautions for the swimmers
and the sail of marine means in each region.
It does not suppress the communal seashore because safety passages are created atregular distances for the
controlled approach of marine means to the coast, marked suitably and light-marked with the navigation light
buoys of our company throughout their whole extent during the night.
The bright orange color and their elevation at the water surface make them exceptionally detectable and stylish.
Being a standard of safety the floating systems are to common interest of public health and prevention of accidents.
With their application, marine space is maintained while simultaneously a secure area of swimming is delimited
and protected from the uncontrollable sail of marine means and the accidents that they have caused in the
past.

Their application is essential in each swimming area, particularly near beaches offering children entertainment
or other amusement for people.
Shark net protection
The bars constitute the most important part of the construction because of their low hydrodynamic resistances while they allow very
high durability against loads from water forces. The bars give to the
construction flotation stability independently the weather conditions.
Their height meets the required height of the upper part of the system and they are installed every 1 m. The bars are made of plastic
and they have very high sun protection that provides high durability
against sun rays, sea water and a antibacterial protection. They are
orange in order to be regognizable in the water and they have alongside glowing rings so as to be distinguishable even during the night.
They have round shape and they have a double internal float made
of polyethylene in order to control the sinking level of each bar to the
required height.
Connector and mooring stabilizer
These are the bars from which the entire construction is tied up and
firmly held from the mooring. They are highly durable against the
lash of sea and its drawing tendencies currents.
They have two floats in the middle of each because of their
great load and they are in stainless metal parts for the secure tying of the anchors’ system.
Furthermore, these bars are used for the assembling of different parts of booms which take place
with 2 stainless steel bolts.
Sewing
This is the connecting tissue of the construction, which connecting the net with the ballasts of the construction.
Two types of sewing are used for the industrial type and hand made type.
Industrial Type: Industrial coated PVC with inner polyester thread is connected with the ropes with high frequency
welding. Also, the coat is connected to the net with double sewing stitches of high durability polyester yarn.
The coat tensile strength :
Warp : 4000*2=8000N/50mm
Weft : 3500*2=7000N/50mm
NET shark SOLUTION
Tear strength :
Warp : 600N*2 =1200N
Weft : 500N*2 =1000N
Add. : UV-protection, Antibacterial stabilizers.
Hand made Type : Extremely high durability yarn type dyneema is
connecting accurately, the net with ropes. Dyneema tensile strength
>=600 Kp.
(Hand made type is suggested to applications where our company
cannot assume the maintenance of the boom as it is very strong and
easily to be repaired after many years).
Design of the net is subject to local conditions like :
- weather circumstances
- duration of use every season
- waves and storms occurrence
- maintenance
- type of sharks and other marine life
- prevailing wind
Guarantees
Our products include a 5 years guarantee against sun exposure andare estimated for a life cycle of 10 years
of periodically permanent deployment 6months/year, even in rough weather conditions to 8Bf.
the System Constructions, with respect and sensitivity for the environment, applies the quality management
system ISO 9001:2000 for the manufacture of its products.

System cost
NET shark SOLUTION
Many factors to analyze :
The effective length of the barrier and its depth
The configuration of the seabed
The existence of pontoons already on site
Maintenance by us or not
Site area (island)
Conclusion
To prevent any shark attacks on tourist, we will put our defences
means at your service.
Swimmers and families of tourists will gain back confidence and take
full advantage of the sea during their stay at the hotel.
Our philosophy is to prevent any risk of accidents and safeguard
the well being and the living space for everyone .
Prevent the extermination of sharks that play a very important role
in safeguarding the marine environment remains a priority!
The advantage of a safety beach is also the security for the tourists
and the protection of the natural place.
In short, a compromise between nature and recreation seems to be
the best for all !
Our high-net system can guarantee not only great protection, but
also an effective barrier against the intrusion of jellyfish or waste
from the sea.
Nets funds for their part, letting the small fish come into shallower
water to breath
The size of the space under the net Marino allows the passage of
several species of fish, to avoid any disturb in the organic cycle of
beach or reef.
