Leading-edge Buoyancy Foam Solutions for Ocean Science
High-performance subsea buoyancy modules for oceanographic applications
All buoyancy modules and equipment manufactured by ALSEAMAR are sold under the BMTI brand name. ALSEAMAR has a large and dedicated manufacturing plant capacity with a fully internalized production process for subsea foam modules.
The Lowest Densities and Reliable Syntactic Foam
ALSEAMAR’s oceanographic buoyancy products withstand the demanding conditions of long-term deployment in deepwater environments.
By combining material technology and design experience, BMTI solutions are designed, formulated and manufactured with high performance foams for a maximised vehicle uplift with long term duration.
BMTI foams offer a wide range of densities and mechanical properties. ALSEAMAR’s design & engineering team will advise on the best foam reference that will provide the best combination to each subsea vehicle, depending on its size, shape and maximum depth. The expert teams can provide both standard foam blocks or custom-shaped buoyancy modules.

The Power of Expert Teams
ALSEAMAR’s human-scale approach enables highly responsive and personalized support from the teams.
The company provides genuine, expert advice to optimize the balance between superior technical performance and long-term durability, ensuring that each solution is tailored to meet the specific needs of their clients.
The teams of experts easily create foam blocks that are specifically designed for seamless integration into vehicles and various applications, making the process smooth and efficient.
A Wide Range of Marine Science Vehicles
ALSEAMAR offers modular installation and permanent subseabuoyancy for flowlines as well as insulation boxes for the sea industry.
BMTI is well known to provide solutions for the oceanography market as its equipment is deployed at great depths over long periods of time.

Deep ocean exploration submersible buoyancy
Human-occupied submersible buoyancy
High Quality at Every Step of Manufacturing
Incorporating BMTI materials into underwater vehicles manufacturing significantly reduces the density and weight of the buoyancy, whilst providing the highest strenght to weight ratio to meet the deep and ultra-deep-water environment demands of both strenght and weight.
Quality and traceability throughout the process, with identification of each block, test sample on each block, etc.
Reasonable production and delivery times
Control of the entire process: R&D & manufacturing, with in-house formulation and manufacturing from A to Z
DNV is the reference third-party organization that qualifies all suppliers capable of manufacturing equipment for this type of deepwater machine.
This will enable ALSEAMAR to open up the demanding market for buoyancy systems for manned submarines, which requires syntactic foams of the highest technical level, and for which every manufacturer must be qualified by DNV.
Specialized and Dedicated Factory
A factory 100% dedicated to syntactic foam, offering an optimal ratio of technical capacity to lead time. This is achieved through strategic investments in both state-of-the-art machinery and skilled personnel, ensuring controlled and reasonable lead times.
ALSEAMAR stands out for its agility and responsiveness, offering the flexibility of a smaller structure while delivering the expertise and solutions of much larger companies. The company’s approach is centered on true collaboration, working closely with their clients to meet their specific needs and adapt quickly to any challenge.
