Qatar Petroleum has let a contract to McDermott International Inc. for detailed design of offshore jackets for the expansion of giant offshore North natural gas field (OGJ Online, July 5, 2017).
The project will add 4.6 bcfd of production capacity in the southern part of the field and includes expansion of LNG production capacity to 100 million tonnes/year (tpy) from 77 million tpy.
The jackets contract is part of offshore work that will include installation of six wellhead platforms and associated field and trunk pipelines.
The offshore facilities will be integrated with three new 7.8 million-tpy LNG trains.
Chiyoda Corp. has the contract for front-end engineering and design of the onshore facilities, to which a fourth train might be added in the future.
Processing of feed gas from the expansion project will yield 3,000 tonnes/day of ethane, 185,000 b/d of condensate, 8,500 tonnes/day of LPG, and 12 tonnes/day of pure helium.
Drilling is to begin next year. LNG production is due by the end of 2023.
