solution to just about any
buoyancy requirement
Flotation
We offer a best-in-class solution to just about any surface or subsurface
buoyancy requirement from customers throughout the world. If we cannot
meet a requirement from our extensive range of off the shelf products, we
apply our experience and engineering expertise to design a new solution.
In addition, with the recent acquisition of a leading firm of naval architects,
we have now added mooring system design to our bespoke product
design capability.
Steel has been the material of choice for surface buoyancy applications
for many decades and we still offer steel buoys to those customers who
prefer them.
However, for more than 20 years, there has been a shift away from the
significant capital and labour costs involved in building, deploying
and maintaining steel products. The growing preference is for modern,
lightweight, low-maintenance forms of plastic buoyancy.
Within the Fendercare Marine group of companies, we have two
designers and manufacturers of plastic buoyancy, both serving a global
customer base.
Australian Commercial Marine (ACM) has a long-established and
market-leading range of mooring and navigational buoys manufactured
from rotationally-moulded polyethylene. They have harnessed a unique
“foam sandwich” variant of this technology, to offer buoys with outstanding
collision-absorption properties. Others may seek to emulate them, but
there is only one genuine range of ACM buoys.
Hippo Marine is a world-renowned UK-based manufacturer of
elastomer-type buoys, the same technology that they use in foam-filled
fendering solutions. This results in self-fendering surface buoys which are
specifically designed to absorb impacts without either suffering or causing
damage, making them the preferred choice for offshore operations.
We can also introduce Kevlar™ reinforcement into the elastomer skin of
the products to offer outstanding durability for heavy-duty work.
We have also recently developed a subsurface buoyancy capability in
a product line now being delivered to offshore and governmental
customers worldwide.
Our product range covers four main product areas:
mooring buoys
navigational buoys
offshore surface buoys
subsurface flotation

Mooring Buoys
Yacht Mooring Buoy
Hippo yacht mooring buoys are manufactured from a
moulded core of closed cell foam covered in protective
polyurethane elastomer. This makes them virtually
unsinkable, even after suffering severe damage.
The standard range of SB mooring buoys (SB1 – SB7) are
recommended for fore and aft mooring systems.
The standard range of SB soft mooring buoys (SB1S
– SB5S) are recommended for single buoy mooring
systems. They are identical in construction to the SB
which allows greater impact absorption.

Commercial Mooring Buoy
Hippo Marine’s self-fendering commercial mooring
buoys are in service with vessel and terminal operators
worldwide – and used by everything from small RIBs up
to cruise ships and supertankers.
Both types of buoy can be supplied in chain-through,
pad-eye or handling crucifix configurations and with
integrated radar reflectors. The cylindrical-type buoys
can also, if required, be fitted with quick release hooks
and lanterns.
The table below reflects what we have designated as
our standard ranges of chain-through buoys, but most
of the buoys we supply are tailored in some way to suit
a customer’s specific requirements.

Fabricated Steel Admiralty Pattern
Mooring Buoy
Fabricated from 8mm steel plate and constructed with
watertight compartments (2 for 5th and 6th Class and 4
for the remainder) each with a manway and drain plug.
Admiralty pattern mooring buoys are finished with
rubber or timber fendering and life chains.
The central open hawse pipe, with reinforced collars
at each end, allows for a large diameter riser chain
to be lead through the buoy, ensuring all loads are
transmitted directly to the mooring itself and not
to the buoy.

Besides the ranges of commonly-requested buoys
listed within this section, we also design and
manufacture a complete range of floats for hoses,
pipes, ropes and many other applications.
For rope use, we have single and double hawser
designs, all manufactured from the same combination
of extremely durable, high-visibility, self-fendering
materials as our ranges of buoys and fenders. These
can easily be tailored to guarantee a specific amount
of buoyancy.
Within the hose market, we are able to offer floating
Y-pieces and reducers in either standard or bespoke
configurations. We also design and supply hose floats.
For pipeline installation work, we offer pipelaying
flotation modules, more details of which can be found
in the subsurface buoyancy section of this publication.
And in response to an FPSO operator off West Africa
who brought us the problem of his offloading hose
getting damaged when coming into contact with riser
chain, we developed a moulded protection system
which we are now supplying to others looking to
minimise hose casualties and related downtime.

Subsurface Buoys
Subsurface Flotation Materials Overview
External Coatings
There are 3 main material possibilities for encapsulating
the core of Hippo subsurface buoys:
polyurethane elastomer is a highly abrasion-resistant,
reinforceable coating which we can either spray-apply or
cast around the foam core. For ultimate durability, this
form of coating can be Kevlar™ reinforced
rotationally-moulded polyethylene is a cheaper and more
uniform method of mass-producing a protective shell for
the foam core in applications where the resilience and
flexibility of PU elastomer is not required
PU paint is mainly used in applications where the core
material is resilient in itself but requires some level of
protection from UV degradation
Applications
The primary product applications for these materials are:
The Materials
pipeline installation buoys
As with surface buoyancy, there are two application
dependent material parameters to subsurface buoyancy:
transponder collars
the foam material which forms the core of the product
the external coating material
Based upon the use our products are being put to and
the depths to which they need to be rated, we select from
a number of possible material combinations to ensure
maximum product life and integrity at minimum cost.
Modsyn™ top-up buoys, general subsea installation buoys
modular subsea buoys
distributed buoyancy modules
submersible/ROV/AUV buoyancy systems
Foams
For shallower depths, we are typically offering either
high-density polyethylene foam or expanded polymer
foam. The significant benefit both these foams offer
over the polyurethane foam, which most other
manufacturers will offer for these depths, is that the
foams we offer are of a closed cell nature. This means
that if the outer skin of a Hippo shallow water buoy is
breached, our customers can be assured that the result
will not be a rapid and catastrophic absorption of water
followed by failure of the product.
For deepwater applications, we are formulating and
processing our own pure syntactic foam into which we
will then generally introduce moulded macrospheres to
reduce the weight and the ultimate cost of the product.

Subsurface Buoys
Modular Subsea Buoy
Wherever there is a requirement to safely moor a
floating offshore structure, it is highly likely that the
mooring system will comprise one or more subsea
mooring buoys.
The principle of these buoys is that the flotation
modules are mounted onto a through-member made of
steel. This steelwork, configured and rated in accordance
with customer requirements, integrates structurally
within the rest of the mooring system, leaving the
flotation units unstressed.
The nature of these modular buoys is that the number
of modules can be adjusted to meet a specific buoyancy
requirement and also that any damaged module can be
replaced in isolation.
This range of buoys offers net buoyancy from 500kg
to 20t, at depth ratings from 250m down to 3000m.
Bespoke buoys can also be manufactured in larger or
smaller sizes.
The matrix showing all possible combinations of
modules, depth ratings and resulting net buoyancies
would be massive. Below you will find line drawings of
the mini, standard, large and maxi ranges. Tell us how
much buoyancy you will require, and to what depth it
needs to be rated, and we will quote you the most cost
effective way to meet that requirement from amongst
these options.

Subsurface Buoys
Other Subsurface Flotation
Our combination of subsea materials technology and
processes allows us to design and supply products for
many other subsurface applications.
These can be as simple as the pictured transponder
collar. However, the projects we get involved in can
also be as detailed as the consulting, design and
manufacturing we were engaged to perform for the
most complex sets of submersible buoyancy ever
produced, also pictured.
Other areas to which we are applying, or have applied
our expertise, include combined jumper/umbilical
flotation and protection and distributed/riser buoyancy.
For the vast majority of work of this type, there are no
specification tables which we can provide to arrange
standard data into a neat format. This is all about
our customers bringing us their subsea design and
operational challenges and working with us to develop
a technically robust and cost effective solution to those
challenges – in which respect we act as an extension of
their own engineering capabilities.
So the service which we are proposing here is the
application of our materials, our experience and our
expertise to assist our customers in finding the best
possible outcomes to their subsea headaches. We
welcome such headaches, and the opportunity to show
our customers how we can solve them for you.
