Construction Begins at Cambodia’s First Offshore Platform
First steel has been cut for the minimum facilities wellhead platform (Mini-Platform) for Apsara, the first oilfield development offshore Cambodia.
The Apsara field in Cabodia Block A lies over the Khmer Basin in the Gulf of Thailand. KrisEnergy, the operator of the field, said that, due to the unproven production performance of the basin, Apsara will be developed in several phases to mitigate risk.
The initial Mini Phase 1A simplifies the original Phase 1A development with a smaller platform, fewer initial development wells, and the use of leased shuttle tankers as opposed to the original plan for a permanent floating storage and offloading vessel (FSO). The Mini-Platform under development is a similar structure to the original 24-slot platform, except that it is smaller and houses fewer wells. Other aspects of the Mini-Platform, including minimal facilities, transfer of produced fluids to the production barge, and the transfer of electrical power from the production barge, are unchanged from the original platform design. KrisEnergy said that a leased FSO will be used in future Apsara development phases.
Mini Phase 1A will feature the Mini-Platform and 5 development wells connected to the Ingenium II production barge for oil, gas, and water processing. Oil will be offloaded to shuttle tankers, with production building to a peak of 7,500 B/D after the planned startup in the first half of 2020.
Upgrading and refurbishment of Ingenium II began in November 2018 at Keppel’s facility in Benoi, Singapore. KrisEnergy said that installation and integration have been completed for all main new packages—power generation, central control room, electrical switch room, living quarters, pedestal crane, electrical transformers, and produced water processing package—and mechanical completion of all systems is scheduled for this month.
KrisEnergy made a final investment decision to proceed with the first phase of development for the Apsara field in October 2017. Last month, it contracted with Profab to supply a minimum facilities wellhead platform for the field. As part of the deal, Profab, a National Oilwell Varco subsidiary, will procure, fabricated, and build the jacket, topsides, and other related accessories for the Mini-Platform, including full pre-commissioning and loading onto a barge for transportation.

Remote Survey: A New Normal for Oil and Gas
On the normally unmanned Valhall Flank West platform, the survey of a 1-year-old box boom pedestal crane featured auto-testing of the automatic overload protection system. A similar inspection program was performed on two knuckle boom cranes on a FPSO vessel in Skarv.
