Seaflex Inflatable Buoyancy Unit(IBU) OverviewHelping contractors work more safely,efficiently and profitably since

Inflatable Buoyancy Units Flexible, Multi-Purpose FlotationReliable and ControllableOptimised for Horizontal DeploymentSeaflex enclosed IBUs are the system of choice where reliable,controllable buoyancy is required. They are particularly suitedfor installation buoyancy on pipeline float-outs, beach pulls andriver crossings. Our IBUs have also been used in applicationssuch as vessel and platform draught reduction in limited waterdepths, and as pontoons for temporary bridges and docks.IBUs are not designed to find their own level on inflation; theymust be held approximately horizontal to prevent tearing of thestrop pockets. Within this context, and unlike versions of IBUsoffered by others, the unique Seaflex end-strop system forces airthrough the IBU as it is inflated - to prevent bulging and resultingfailure. Circumferential strops built into the IBU itself deal withshallow angles, enabling the IBU to cater to load angles of up to10 or 15 degrees (where greater working angles are expected,Seaflex Mono Buoyancy Units are the perfect answer).Constructed from High Tensile Trevira Polyester 3/3 base clothcoated with heavy duty UV stabilised PVC coating, our IBUs comefitted with stainless steel camlock terminated inflation pointsand 38 mm diameter pressure relief valves each capable ofreleasing 80 cubic feet (2.3 cubic metres) of air per minute. TheIBU operates at 2 psi over ambient to ensure maximum volume,and therefore full displacement, during operation.Our IBUs offer significant advantages over ALBs where staticas opposed to dynamically-ascending buoyancy is required,especially in relatively shallow water. They are also very stableunder way and can be towed, dependent on load and sea state,at up to 2 knots.Designed for Ease of HandlingThe multiple attachment points of our IBUs assist in spreadingthe lift points across the load. Their relatively low verticalheights and short strop configurations are a key advantagewhere water depth is limited or a load needs to be supportednear to, or on the surface. We have designed-into all our IBUs anintuitive system of ensuring accurate strop spacing; a spacinglink strap joins the fixed ring strop terminations together. And,just like our range of ALBs, our IBU’s have integral ladders tofacilitate handling.Typical 5 tonne capability IBUs weigh just 46 kg, making them aneasily handled item for two rigging crew.Extremely Cost-Effective: Hire Options Available,Transport Costs MinimisedSeaflex has over 25 years’ worth of experience of themanufacture, rental and maintenance of the world’s largest stockof certified, best in class, IBUs. Our fleet of IBUs have worked inevery ocean and sea, and on every populated continent.With a shipping weight of approximately 1% of inflated liftingcapacity, Seaflex IBU’s are first choice for contractors requiringsignificant, compact lift; a single 20 foot shipping container canhold a massive 500 tonnes of buoyancy.User-controlled Buoyancy VariationDuring the mobilisation phase, and particularly importantduring demobilisation, the air can be introduced and releasedin a controlled manner into single or multiple units to allow theload to settle gently into the correct position, or to repositionit if required, before the IBUs are vented and then released in acompletely safe manner with no uplift force remaining.www.uniquegroup.com1

Our CredentialsOver 25 years later, our biggest standardbag is 200 times larger than that atan industry-leading 100,000kg andwe employ around 30 skilled staff atour custom-built 30,000 square footmanufacturing facility in Cowes onthe Isle of Wight.In 2011 Seaflex was acquired by the Unique Maritime Group,a global provider of integrated support services for theoffshore sector. Unique Maritime Group’s expanding networkof companies are specialists in ROV, diving, survey, NDTand engineering services. With the benefit of UMG’s globalfootprint and support structure, Seaflex is these days evenbetter placed than ever to meet the needs of its customers– no matter where in the world they are working, nor howchallenging or urgent their requirement may be.As you would expect of a company working in an industrywhere the concepts of quality and safety are paramount,all our work is carried out within a system which complieswith the ISO 9001- 2008 Quality Management Standard forfull traceability – and we now have also gained ISO 14001Environmental accreditation and ISO 18001 Health and Safetyaccreditation for our manufacturing operation. We havealso had independent verification of the compliance of ourSeaflex WaterLoad bags with LEEA 051 guidelines and ofour Buoyancy bags with the requirements of IMCA D-016. ABShave also issued us with full Product Design Assessment (PDA)certification for our main products.But any company can talk about the vast amounts of testing,certification and accreditation which have been carried ontheir products – fewer companies can substantiate suchclaims. Seaflex is one of those which can back up their claims– however, our credibility does not come from bits of paper: itcomes from our customers, from the work we have being doingwith them for over 25 years, and from the fact that they keepcoming back to us time and time again.YQUALIERTSTSURANCEASD ’S REGOYILLSeaflex manufactured our very firstrange of lift bags for rental and sale toservice the diving industry in 1987, insizes up to 500kg.IS O9001 IS O140 01OH SAS 1 800 1UKASMANAGEMENTSYSTEMS001www.uniquegroup.com3
