ABB proves subsea power system for offshore oil and gas
Swiss-Swedish technology multinational ABB has completed a 3,000-hour shallow water test proving that its subsea power distribution and conversion technology system for the offshore oil and gas industry is commercially viable.
The technology will allow energy companies to access a 100 MW power supply over distances up to 600km and to water depths of 3,000m using a single cable with little or no maintenance for up to 30 years.
The complete system incorporates a number of electronics and control systems that are proven to operate underwater, improving on previous iterations of the technology that could only use a step-down transformer and a transmission cable.
According to ABB, this technology could significantly reduce power consumption in oil and gas operations by powering pumps and compressors on the seabed, closer to reservoirs.
These energy savings would also reduce carbon emissions from offshore operations, which could be reduced further through future integrations with renewable energy sources. The shallow test project in Vaasa, Finland also used a system to recycle its own waste heat as power, reusing 85%-90% of its waste heat.
Based on a specific field development case, the technology could offer offshore oil and gas companies capital expenditure savings of more than $500m by linking eight pumps or consumers through a single cable.
The system was researched, designed and developed as part of a $100m joint industry project (JIP) initiated in 2013 between ABB and Norwegian oil and gas company Equinor, with Total and Chevron as partners.
ABB told Offshore Technology that the system is ready to be deployed as early as the first quarter of 2020, but will likely be subject to 12 months of further study to account for administrative or legal approval.
