Installation Buoyancy
Our broad range of modular buoyancy units ensures that buoyancy requirements, ranging from a few kilograms to 50 tonnes, can be effectively met.
The flexibility of our products and equipment allows for easy reconfiguration of net buoyancy by adjusting the number of modules. Even for the smallest series, this reconfiguration process is quick and can be conveniently performed offshore, if necessary. Designed for repeated use, our modular buoys offer a reliable and cost-effective solution for subsea installation, operation, or decommissioning projects.
In addition to standard installation buoyancy, we provide various specialised solutions, including marker buoys with options for lights, radar reflectors, and AIS-functionality, tie-in buoyancy for pipeline deployment and distributed buoyancy for cables and umbilicals.
Product overview
Tie in Buoyancy
This product is perfectly designed for buoyancy support of pipeline deployment. Either the buoyancy units can be customer specifically designed to fit a pipe diameter, or a universal design can be used. In addition, adaptors can be supplied to existing units for fitting several diameters.

Spherical Buoys
Our range of spherical buoys consists of a large variety of sizes and can be delivered for several depths. The buoys consist of a unit, and are adapted for use where the need for buoyancy is limited.
Padeyes can be delivered as optional equipment.
The holes are also excellent for manual handling.

AIS Marker Buoy
AIS Marker Buoy is a rugged marker buoy for offshore installations. It contains type 3 AIS and a GPS synchronized flash light. The buoy is self-stabilized With a low center of Gravity to prevent the buoy from floating upside Down. An Integrated handle enables short distance transportation. Safer Storage on deck due to two flat Surfaces on opposite side of the Integrated handle.
