The 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.

Energy demand to plateau Energy demand is set to plateau after 2030, driven by greater efficiency with the wider application of electricity. A rapid decarbonization of the energy supply means renewables are set to make up almost half of the energy mix by 2050, although gas will become the biggest single source of energy. This is according to DNV GL’s inaugural Energy Transition Outlook.
Historically, energy demand and CO2 emissions have moved broadly in line with GDP and population growth, but that relationship will unravel, said the report. Electrification, particularly with the uptake of renewables, will change the way energy is supplied and consumed. While the global economy and world population are set to grow modestly, energy demand will flatten out and CO2 emissions will drop sharply.
DNV GL forecasts that renewables and fossil fuels will have an almost equal share of the energy mix by 2050. Wind power and solar photovoltaics (PV) will drive the continued expansion of renewable energy, while gas is on course to surpass oil in 2034 as the single biggest energy source.
Oil is losing ground as a source of heat and power, and is set to flatten from 2020 through to 2028 and fall significantly from that point as the penetration of electric vehicles gains momentum. Coal use has already peaked.
The global energy transition will occur without a significant increase in overall annual energy expenditure, said DNV GL. The world’s energy will cost less than 3% of global GDP compared to the current level of 5%. Solar PV and wind are set to decrease by 18% and 16%, respectively.
Electric vehicles will achieve cost parity with internal combustion vehicles in 2022, and by 2033, half of new light vehicle sales globally will be electric.
