Njord DBM (Distributed Buoyancy Modules) are typically used between a subsea structure and a surface vessel or platform to hold pipelines in a specific geometric configuration to prevent overutilization of the system. The two main functions of Njord DBMs are to provide uplift and maintain location along the riser, to hold the project-specific riser configuration.

Njord SBM (Standardized Buoyancy Module) is a modular version of Njord DBMs, allowing smaller elements to be stacked together to customize uplift requirements for each specific project. The modular buoyancy segments are designed to mechanically lock around the clamp, securely attaching the assembly to the desired location on the riser.

Njord SBMs design incorporates synthetic feet to the bottom of the finished assembly to prevent handling damage and reduce vessel installation time.
