Flotation

IntroductionWe 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, weapply 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. We still offer steel buoys to those customers who prefer

them, as detailed overleaf.

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 are 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 governmentalcustomers worldwide.

Our product range covers four main product areas as detailed overleaf

A3-10045 Fabricated Steel Admiralty

Pattern Mooring Buoy

Fabricated from 8 mm steel plate and constructed with

watertight compartments (2 for 5th & 6th Class and 4

for the remainder) each with 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.

A3-30004 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

range except for the use of a exible closed-cell foam

which allows greater impact absorption.

A3-30005 Hippo Lite and Super-Lite Buoys

Whether configured as navigational marks in

accordance with IALA guidelines, or fitted out as

databuoys, the largest buoys in the Hippo family offer

outstanding durability and stability and are in service

in some of the most challenging environments on

the planet.

These buoys are fully modular, and the superstructure

is engineered to both minimise windage and to accept

large equipment packages.

The flexibility of our technology allows to adopt a blank

page approach with users who are looking to achieve a

step change in the efficiency of their buoy operations or

to incorporate very specific design features.

withstand gale force winds.

Access to the door section is via an external ladder. The

ladder is removable to minimise theft or vandalism. Access

to the lantern is via an internal ladder at the top. The top

platform is fitted with guard rails to enable safe access to

the lantern for maintenance purposes.

The towers can be fitted with stainless steel frames to sup-

port solar panels.

Each tower is supplied complete with Lifting Davit kit for

on-site assembly.

The batteries can be stowed either at door level or at

ground level within the cone section.

Colours are in accordance with IALA marking standards.

Towers have been certified to withstand winds of up to 56metres per second (125mph).

A comprehensive range of lighting systems is available.

Other Offshore Flotation and Protection

Besides the ranges of commonly-requested buoys

listed within this section, we do 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, and

which 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, on which more detail can be found

in the sub-surface 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.

Flotation Subsurface Buoys

The MaterialsAs with surface buoyancy, there are two application

dependent material parameters to sub-surface buoyancy:

The foam material which forms the core of the product

The external coating material

Based upon the use to which our products are being

put, 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.

FoamsFor shallower depths, we are typically offering either

high-density polyethylene foam or expanded polymer

foam. The significant benefit which 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 Flotation Materials Overview

External Coatings

There are 3 main material possibilities for encapsulatingthe 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.

ApplicationsThe primary product applications for these materials are:

Pipeline installation buoys

Modsyn top-up buoys, general subsea installation buoys

Transponder collars

Modular subsea buoys

Distributed buoyancy modules

Submersible/ROV/AUV buoyancy systems


28/32




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 oftheir 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.

Modsyn top-up buoys, general

subsea installation buoys

Manufactured from the same syntactic foam formulations

as our ranges of larger subsea buoys, Modsyn is the perfect

solution when small, configurable amounts of buoyancy

are required for cable or umbilical support, as ROV trim

buoyancy or as a general-purpose installation tool.

Modsyn does offer a number of operational advantages

over alternative products available in the market:

Easily lashed via the central through-hole

Multiple units can be configured together via two other

lateral through-holes

Flat-sided for easy storage on land and easy use on deck.

Modular Subsea Buoys

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

from steel. This steelwork, configured and rated in

accordance with customer requirement, 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 bereplaced 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. Underneath you will find line

drawings and basic dimensions of the Mini, Standard,

Large and Maxi ranges. Tell us how much buoyancy youwill 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.
