Njord DBM (distributed Buoyancy Module)

Njord DBM (Distributed Buoyancy Module)

Njord DBMs are typically used between a subsea structure and a surface vessel or platform. The clamping solution allows the DBMs to be fitted at any point along the length of the pipeline.

Provide uplift

The uplift is generated by a two part buoyancy component: a clamp and the buoyancy element.

Maintain location along the flexible pipeline or cable

A clamp securely attaches the assembly to the desired location on the pipeline. The buoyancy elements are assembled to mechanically lock around the clamp and are secured with a fastening system.

Compliant clamping systems

Compliant systems encapsulate large flowline tolerances and expansions or contractions through the use of compliant contact pads.

Installation Buoyancy

To reduce the weight of the flexible pipeline or cable during installation, discrete buoyancy modules can be strapped to the flexible pipeline or cable on board the vessel or in the case of a shore pull, installed on land.

Key Applications

Deep water buoyancy systems

Insulated risers

Dynamic applications
