Solutions for Subsea Buoyancy

Designed with customers in mind, our Subtec^® syntactic buoyancy materials provide maximum uplift for a given volume, with some of the lowest-density materials available. We understand the need for high-performance, reliable solutions, especially when engineering buoyancy for manned applications.

With densities from 385 – 650 kg/m³ designed for use in seawater depths of down to 11,500 metres, our Subtec^® range of high-performance, low-density subsea buoyancy materials is specifically formulated for subsea buoyancy applications including remotely operated vehicles (ROVs), autonomous underwater vehicles (AUVs) and human-operated vehicles (HOVs).
