Modular Buoyancy - Subsea Buoyancy - Subsea - Trelleborg Offshore

Modular Buoyancy

Modular Subsea Buoys are suitable for mooring, weight compensation and installation of subsea equipment. The buoy flotation core varies in density and performance to suit each individual project water depth.

Risk elimination

Each module interlocks via male and female spigots thus eliminating the risk of the modules rotating.


The polyethylene skin gives the modular subsea buoys a tough exterior that protects the buoyancy core during handling and deployment.


The modular nature of the design allows the net buoyancy to be adjusted to suit each individual application.


The bright yellow finish and the highly reflective tape guarantees that the buoys are easy to spot in the ocean.
