CALGARY, Canada  Valeura Energy is addressing damage to moorings serving the Wassana oilfield redevelopment in the Gulf of Thailand.

Following a charter agreement, the third-party operated oil storage vessel MT Jaka Tarub mobilized to the field late last month. During startup preparations, the vessel impacted the field’s catenary anchor leg mooring (CALM) buoy, damaging certain offloading components. 

No personnel were injured; production had not yet started, and there was no discharge of fluids.

Valeura is collaborating with Thailand’s upstream regulator, the Department of Mineral Fuels, on a safe restart of production operations. Thus, it will involve a comprehensive inspection to assess damage and verify the operational integrity of the offloading system.

Earlier this year, following completion of upgrades, maintenance and inspection work on Wassana’s Ingenium mobile offshore production unit (MOPU), the company received formal notice of the MOPU’s recertification.

Valeura is also preparing for infill drilling operations, having agreed last year to charter the PV Drilling I jackup for a five-well program on Wassana. The rig should arrive on location during the third quarter.
