As a global operator worked to lower CO₂ emissions during a drilling campaign, James Fisher supported our customer's goal with efficient electric compressor technology in the Norwegian North Sea.
Customer challenge
This campaign needed a reliable bulk transfer solution for drilling cuttings that could perform continuously in highly constrained deck space.
Conventional diesel compressors required larger footprints, frequent maintenance, and generated higher emissions, creating operational inefficiencies and conflicting with the campaign's decarbonisation targets.
A more compact, lower-emissions solution was required to maintain uptime and performance without increasing operational risk or compromising deck capacity.
Solution for our customer
To address these constraints, James Fisher implemented a compact electric compressor solution tailored to available deck space and operational requirements.
Five ST25EL electric compressors were configured in a stacked arrangement beneath the existing deck structure - maximising use of limited space while maintaining required performance.
Key features
Customer impact
- CO₂ emissions reduced by 160 tonnes - equivalent to c. 1,060 one-way flights from Oslo to London
- Improved reliability, with service intervals extended to 3,000 hours - 10x longer than equivalent diesel units
- Optimised use of constrained deck space through compact, stacked installation
- Cost efficiency, achieving combined savings through reduced duel use, maintenance and avoided carbon tax.
