Our Enclosed Flotation Bags (EFB) are fully enclosed flotation bags for floating or supporting ships, vehicles, pipelines and structures – at the surface and in shallow water. Six standard sizes from 135 to 3,300 kg of buoyancy, delivered ready to use with stainless steel quick couplers, ball valve and pressure relief valves.

Features of our inflatable salvage tubes

Buitink Technology's inflatable floats have a number of important and distinctive characteristics.

• Due to the polyester fabric and its EVA/PVC co-polymer coating, the material is very flexible and also very easy to repair (with glue or a hairdryer with hot air);
• Our inflatable salvage bags are made of a very strong coated polyester fabric with a tensile strength of no less than 8,000 N/5 cm;
• Due to the high-strength polyester fabric type IV, the material with which the flotation tubes are made has a puncture resistance of no less than 2,150 N (in contrast to many competing products that only reach 1,750 N);
• Buitink Technology's inflatable salvage bags have no sharp corners (they are rounded off and smooth), which makes these enclosed flotation bags more robust and less likely to be damaged;
• Buitink Technology's enclosed flotation bags are lightweight! Up to 50% lighter than the competition's enclosed flotation bags, while the lift capacity is at least 10% higher;
• The inflatable salvage tubes require little maintenance and are very easy to clean;
• We can personalize the bags and provide them with your logo and desired print! That means that you can sell them under your own label if so required.

Top-quality material

• EVA/PVC co-polymer coated polyester fabric - high-strength and heavy-duty;
• Fabric's tensile strength: 8,000 N/5 cm;
• Puncture resistance: 2,150 N (in contrast to competitor's products, which often do not reach more than 1,750 N);
• Resistant to many chemicals;
• High UV-resistance;
• Very easy to repair (with glue or a hairdryer with hot air), unlike materials coated with PU or TPU;
• Highly flexible and lightweight material.

Certification & quality

• IMCA D-016 – designed and manufactured following the IMCA D-016 guidance: safety factor ≥ 5:1 on the WLL, webbing slings ≥ 7:1. Every bag carries a unique serial number and is delivered with a test certificate and user manual.
• Webbing slings CE-marked to EN 1492-1. No harmonised EU standard exists for underwater lift bags themselves; the industry works to IMCA D-016.
• Individually tested – pressure test, relief-valve function test and a 24-hour air-tightness check before shipment.
• ISO 9001 certified manufacturer; produced entirely in-house in Duiven, the Netherlands. EU origin: no import duties within the EU.

Welded patches instead of pockets

The lifting straps on our flotation bags are attached to HF-welded patches that spread the load over a large fabric area – not sewn-on pockets, which can tear out in practice. Combined with the extremely strong fabric (tensile strength 8,000 N/5 cm, puncture resistance 2,150 N) this gives a demonstrably more robust load introduction.

Applications

• Salvage of ships and submerged vehicles
• Buoyancy for pipeline transport and installation
• Draught reduction and pontoon support
• Emergency response and shallow-water work (seawater-resistant SW version)
