Dockwise Ltd. has installed the production platform at the SHWE gas development in Myanmar's A-1 offshore block, setting a company record for the heaviest float-over installation. The 30,000-ton topsides were launched from the HYSY229 barge, which arrived at the Bay of Bengal location Dec. 8, 2012, from Hyundai Heavy Industries' fabrication yard in Ulsan, Korea. Installation of the platform, which accommodates 200 people along with drilling and production equipment, surpassed Dockwise's previous installation record of 21,000 tons. The SHWE project in blocks A-1 and A-2 is operated by a consortium led by Daewoo International. The project, 70 km (43.5 mi) offshore Myanmar, will produce and process up to 500 MMcf/d of gas to China.

Delivery is expected in 2015 from Keppel Singmarine's yard in Singapore.

McDermott also picked up a $230-million job with Pemex for delivery of the PB-Litoral-A production platform to the Litoral Tabasco Tsimin-Xux fields in the Bay of Campeche offshore Mexico. McDermott will conduct FEED, EPCI, and commissioning of the eight-legged, 1,800-m ton (1,984-ton) jacket and 4,500-m ton (4,960-ton) topsides, along with tripods, bridges and piles. Engineering will take place in McDermott's offices in Houston and Chennai, India. McDermott's fabrication yard in Altamira, Mexico, will have around 550 workers on the project at the peak of construction, with installation scheduled to be completed in 2Q 2015 using theIntermac 600 floatover barge and the Derrick Barge 50.
