Subsea successThe Åsgard subsea compression system has officially reached the highest Technology Readiness Level (TRL) 7, with both trains surpassing 10,000 operating hours. The subsea facility demonstrated an availability close to 100%. The few interruptions were caused by failure of the power supply from the vessel. MAN’s HOFIM motor-compressors were supplied to Statoil’s contractor Aker Solutions for installation in the North Sea. The units help to extend the reservoirs’ productive life on the Åsgard field for another 15 years. Overall, 306 million barrels of oil equivalent will be added. The adapted subsea HOFIM features a tailored motor design, casings designed for 220 bar pressure, a 7-axes active magnetic bearing system and a cooling gas extraction. Compressors maintain output as reservoir pressure at gas producing fields drops over time. But they are generally installed on platforms above sea level. The two 11.5 MW HOFIM motor-compressor-units at Åsgard are the first compressors in operation 300 meters below sea level. MAN subsea unitAnsaldo contract Glow Energy in Thailand awarded a long-term service agreement (LTSA) to Ansaldo Energia for the Glow Energy Phase 5 power plant, 200 km southeast of Bangkok. It generates 328 MW of electricity plus 160 tons/hour of steam to support ...
