ExxonMobil Exploration and Production Malaysia Inc. has successfully installed the topsides of Tapis R offshore platform at the Tapis field off Terengganu, Malaysia.
Tapis R— one of the largest offshore platform in Southeast Asia—is a part of the US$3.1 billion Tapis Enhanced Oil Recovery (EOR) project in which ExxonMobil and JV partner Petronas Carigali Sdn Bhd invest in new oil and gas assets to help ensure reliable and sustainable energy supplies for Malaysia.
The Tapis R topsides were constructed as one large integrated deck, including gas compression and water injection facilities, production-processing equipment, utility systems and living quarters for 145 people. The topsides, designed and constructed locally, were fabricated by Malaysia Marine & Heavy Engineering under a $434 million contract awarded by ExxonMobil in November 2011.
The combined topsides and jacket weigh about 23,500 tonnes and was the first platform to be installed by EEPMI using the float-over method.
The contract also included construction of the Tapis Q riser platform, which was installed in October 2012, and the installation of access bridges linking the new Tapis R and Tapis Q platforms with the existing Tapis B platform. About 50 kilometers of new pipeline were also installed to distribute gas and water injection from Tapis R and to receive full-well stream production from the existing Tapis platforms, while a main oil pipeline was installed to export production from Tapis R.
Hook-up and commissioning is expected to continue in the next few months at the Tapis R platform to prepare for water-alternating-gas injection activities to start in the 3Q 2014.
