solution to just about any buoyancy requirement Flotation
We o er 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 o the shelf products, we apply our experience and engineering expertise to design a new solution. In addition, with the recent acquisition of a leading rm 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 o er steel buoys to those customers who prefer them.
However, for more than 20 years, there has been a shift away from the signi cant 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 sandwic h” variant of this technology, to o er 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- lled fendering solutions. This results in self-fendering surface buoys which are speci cally designed to absorb impacts without either su ering or causing damage, making them the preferred choice for o shore operations. We can also introduce Kevlar™ reinforcement into the elastomer skin of the products to o er outstanding durability for heavy-duty work.
We have also recently developed a subsurface buoyancy capability in a product line now being delivered to o shore and governmental customers worldwide.
Our product range covers four main product areas: mooring buoys navigational buoys o shore surface buoys subsurface otation

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 su ering 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 cruci x con gurations and with integrated radar re ectors. The cylindrical-type buoys can also, if required, be tted with quick release hooks and lanterns.
The table below re ects 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 speci c requirements.

Besides the ranges of commonly-requested buoys listed within this section, we also design and manufacture a complete range of oats 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 speci c amount of buoyancy.
Within the hose market, we are able to o er oating Y-pieces and reducers in either standard or bespoke con gurations. We also design and supply hose oats.
For pipeline installation work, we o er pipelaying otation modules, more details of which can be found in the subsurface buoyancy section of this publication.
And in response to an FPSO operator o West Africa who brought us the problem of his o oading 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 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 exibility 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 Modsyn™ top-up buoys, general subsea installation buoys dependent material parameters to subsurface buoyancy: transponder collars modular subsea buoys the foam material which forms the core of the product distributed buoyancy modules the external coating material submersible/ROV/AUV buoyancy systems 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.
Foams For shallower depths, we are typically o ering either high-density polyethylene foam or expanded polymer foam. The signi cant bene t both these foams o er over the polyurethane foam, which most other manufacturers will o er for these depths, is that the foams we o er 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.

Modular Subsea Buoy
Wherever there is a requirement to safely moor a oating o shore 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 otation modules are mounted onto a through-member made of steel. This steelwork, con gured and rated in accordance with customer requirements, integrates structurally within the rest of the mooring system, leaving the otation units unstressed.
The nature of these modular buoys is that the number of modules can be adjusted to meet a speci c buoyancy requirement and also that any damaged module can be replaced in isolation.
This range of buoys o ers 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 nd 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 e ective way to meet that requirement from amongst these options.

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 otation and protection and distributed/riser buoyancy.
For the vast majority of work of this type, there are no speci cation 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 e ective 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 nding 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.
