JAKARTA (Rambu Energy) – KrisEnergy Ltd, an oil and gas company listed on the Singapore stock exchange, said it is currently refurbishing its mobile offshore production unit (MOPU) at a drydock in Batam, Riau province.
The MOPU will be mobilized to the Wassana oil field in the Gulf of Thailand once the refurbishment works are completed, KrisEnergy said in a statement.
The Wassana oil field is located in the G10/48 block in the Gulf of Thailand. The first phase of the development of the block will involve 14 development wells, which will be connected to a fixed production platform. The processed oil will then be rerouted to a floating storage and offloading vessel (FSO) via pipeline.
On Oct. 27, 2014, KrisEnergy chartered the Rubicon Vantage FSO vessel and a catenary anchor leg mooring (CALM) buoy for utilization on the Wassana oil development in the G10/48 licence area in the Gulf of Thailand.
The Wassana field is expected to begin production in the second half of 2015.
The Rubicon Vantage is a double-hull FSO facility owned by Rubicon Vantage International Pte Ltd and has been operating in the Gulf of Thailand since 2008. The vessel is 228.6 meters in overall length and has a storage capacity of 597,206 barrels. It can accommodate up to 40 persons.
The CALM buoy is supplied by Equatoriale Services Pte Ltd. Its hull is moored to the seabed using six mooring chain legs guided through rotating chain stoppers and connected to high capacity power anchors, KrisEnergy said earlier.
A turntable is located on top of the hull to accommodate FSO mooring hawsers and floating hoses. A proprietary-designed dual-path swivel unit enables the transfer of fluids during vessel rotations.
Fluids are then transferred from the CALM buoy to the FSO via floating hoses protected by marine breakaway couplings. This widely-used technology enables safe mooring of the vessel while guaranteeing the transfer of crude oil and water during weather-vanning of the FSO.
“With the FSO and CALM buoy contracts, most of the key elements for the Wassana development – facilities, drilling contract and now offloading and storage – are in place and we are on track to take the field into production next year. We plan to coordinate further exploration in G10/48 at the same time,” Chris Gibson-Robinson, Director Exploration & Production of KrisEnergy said.
KrisEnergy holds 100 percent working interest in G10/48, which covers 4,696 sq km over the southern section of the Pattani Basin in water depths up to 60 meters. The licence contains three oil discoveries – Wassana, Niramai and Mayura – in various stages of development. (*)
