Whether a single 50kg air lift bag to support a small subsea tool, or a few hundred inflatable buoyancy modules to assist with a pipeline shore pull operation, you can be assured that Seaflex not only now how to make, test and certify these products – we also know how to support them.

We offer full project-cycle support.  From our first involvement at bid stage we can offer no-cost, no-obligation advice for your engineering team as to how to integrate our buoyancy modules or buoyancy systems onto your structure, with whatever accessories they may require - and then assist your operations team in the development of their project methods.  And at the sharp end of the project, once Seaflex bags have been delivered to you, we can put a Seaflex technician at your site or onboard your vessel to ensure the most efficient and effective use of our equipment for you right at the point where you come to use it.

Inflatable buoyancy has many advantages over solid steel or plastic alternatives.  It is much less expensive to purchase (and much less again to rent buoyancy modules from Seaflex, an option not offered by any other manufacturer).  It packs down small and weighs less than 1% of its capacity, so making it very cost-effective to transport and very quick and easy to work with onsite.  It also allows you to only introduce buoyancy into an operation at the moment it is needed, and so can be easily secured un-inflated to a structure, or taken underwater by divers for connecting and activating as required.

Whereas most other manufacturers of inflatable buoyancy are primarily looking to sell their equipment, Seaflex is mainly a buoyancy rental company.  So the success of our business does not depend upon repeatedly selling replacement buoyancy products to the same customers: it is very much in the interest of Seaflex to ensure that our air lit bags and inflatable buoyancy modules are designed as well as they can be and that they are built to last – to give us the best possible return on them within our rental fleet via intensive use over a long period of time.  Those who rent buoyancy from Seaflex gain access to the best bags in the business at the lowest cost to their project. And as the bags we sell to customers are exactly the same as those we put into our rental fleet, customers who opt to purchase Seaflex buoyancy from us also reap the benefit of this unique philosophy.
