Aquaterra Energy has received a contract to design and build a freestanding wellhead support structure (WSS) for oil production operations, offshore of Peninsular Malaysia in the South China Sea.

The WSS will be installed in water depths of 65m and linked to a mobile offshore production unit (MOPU) where oil will be processed and sent back to the WSS for exporting through a pipeline to a remote floating storage and offloading vessel (FPSO).

The structure will be equipped with four outer environmental well conductors and two subsea structures bracing the subsea span.

Richard Miller, Aquaterra Energy operations director, said the minimal facilities platform allows the use of dry Xmas trees, and reduces the overall development costs and delivery time, while employing proven drilling rig techniques to install the WSS.

"The structure will be equipped with four outer environmental well conductors and two subsea structures bracing the subsea span."

"The WSS topsides, having a total installed mass of [more than] 300 tons, is supported by four 36" x 2" leg conductors tied together by two subsea structures," said Miller.

Aquaterra Energy’s Malaysian partner is currently working on the fabrication stage of the project, which once completed will allow the transportation of the two subsea structures and the WSS topsides for installation by jack-up drilling rig.

Patrick Phelan, Aquaterra Energy managing director, said: "After completion of commissioning and tie back to the MOPU, the oil will flow from the 16 oil production wells, via the WSS, onto the MOPU and then return back to the WSS for connection via the Export pipeline to the remotely sited FSO some 14 kilometres away."
