Subsea Compression and the Ormen Lange Moon Landing
3 project. The resolution - diagnosing and fixing a software bug - was a testament not just to world-record engineering, but to a collaborative culture that Hjelmeland believes was essential to the project's outcome. The groundwork laid during that onshore test led to a remarkably smooth startup offshore, a success echoed by Shell's Project Director at the Ormen Lange Phase 3 project, Richard Crichton. "When we carried out the final commissioning, it only took us 20 days from starting the compressors until we reached full power, which is quite extraordinary," he said.Richard Crichton
