SUBSEA ELECTRIFICATION SYSTEM ENABLES THE OIL AND GAS INDUSTRY TO TAKE THE DEEP-WATER PLUNGE

摘要

In 2013, ABB and its joint industrial partners, Equinor, Total and Chevron, began an expansive project to design and test a complete subsea electrification solution for the oil and gas indus-try. To enable operations at remote locations in ultra-deep waters, ABB developed modular equipment – components and assemblies – that integrate to form a subsea electrification system. 1 The system consists of variable speed drives (VSDs) switchgear and a protection and control system for the transmission, distribution and conversion of power to subsea pumps and gas compressors at a peak capacity of 100 MW to water depths up to 3,000 meters; and with trans-mission distances up to 600 km with lifetime requirements for up to 30 years. Topside area is freed, power supply demands and greenhouse gas emissions are reduced.
