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.
