A major step toward zero-emission rig operations

PSW Power & Automation AS has secured a new milestone contract: a full 4.4 MVA shore power system to cut emissions from a rig during its year‑long yard stay in the Bergen region. 

The rig will be connected to land-based electrical power instead of running diesel generators throughout its yard stay. This shift eliminates significant CO₂, NOx and particulate emissions—improving local air quality and reducing noise for surrounding communities.

A comparable PSW system has demonstrated the ability to save one tonne of marine diesel per port call, equal to 3.2 tonnes of CO₂, when used by large vessels. Over a full year, the environmental impact for a rig is substantially higher, making this installation one of the region’s most effective emission‑cutting measures.

The technology behind the 4.4 MVA solution

  • High‑voltage capacity up to 4.4 MVA — enabling stable power delivery to large rigs and offshore units.
  • Flexible voltage output (11 kV / 6.6 kV) — ensuring compatibility with a wide range of rig electrical systems.
  • Advanced control and monitoring — integrated control systems and updated HMI interfaces for safe, efficient operation.
  • Modular, container‑based design — fast installation, easy relocation, and minimal yard disruption.
  • Built by specialists in electrification and renewable energy — PSW’s expertise spans power systems, electrical infrastructure, energy storage, and control systems.

Benefits for the rig, the yard, and the region

  • Massive emission reductions during the entire yard stay.
  • Lower operational costs by replacing diesel consumption iwth clean grid power.
  • Reduced noise and vibration, improving working conditions and community impact.
  • Compliance with tightening environmental regulations for ports and offshore assets.
  • Strengthening Bergen`s position as a hub for green maritime technology.
