McDermott engineering solution drives successful installation

McDermott International, Inc. has completed the installation of a 3086 t central processing platform topside using the tight-slot float-over method in the Kepodang gas field, Muriah Working Area, offshore Indonesia for PC Muriah Ltd, a wholly-owned subsidiary of PETRONAS. This brings the installation of all structures for the Kepodang project to a close.

McDermott commenced operations on this fast-track project, one month after the contract was awarded, in January 2013.

“The overall success of this project was made possible by the smart engineering of the float-over sequence to position the CPP topside next to an existing wellhead module already installed on the jacket at the installation site,” said Hugh Cuthbertson, Vice President and General Manager, Asia Pacific. “Our global team of in-house engineering experts, high performance fabrication at our Batam, Indonesia yard and our strong supplier relationships in Indonesia were our key differentiators. We are also proud to be recognised by PETRONAS as “Best Contractor HSE Performer 2013” for our exemplary project safety record.”

The project scope included procurement, construction, installation and commissioning of the CPP topside and jacket, a wellhead module, a wellhead platform and jacket, 1.7-mile-long 10 in. diameter infield flowline, and installation of remote control facilities at an onshore receiving facility. The total weight of overall facilities is close to 11 000 t.

The Kepodang field is located approximately 112 miles northeast of Semarang, Central Java, in water depths of up to 230 ft, and is expected to supply gas to the Tambak Lorok power plant in Semarang, Central Java.
