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.
