Hallin completes subsea intervention at Bualuang field

Hallin Marine has completed an urgent project in the Bualuang oil field off the coast of Thailand following damage to subsea structures.

The work centred on the inspection and repair of the mooring and riser system at a floating production, storage and offloading (FPSO) facility.  The project was managed from Hallin’s SOV Windermere.

An initial third-party ROV inspection in partnership with Rubicon Offshore International was commissioned by the client to determine the nature and extent of any damage, Hallin was then tasked to provide saturation diving services for further inspection and to stabilise the installation before conducting repairs.

The work entailed the unraveling of flexible risers, control umbilical and mooring wire, the removal and subsequent replacement of the oil production riser assembly and other subsea structures, resulting in a safe and efficient return to production. The project commenced on 6 January and production resumed on 13 February.

“I want to express our gratitude towards everyone involved in this project,” states Andre Vogel, Operations Director at Rubicon. “It was an excellent achievement in a six week time frame and would not have been possible if we did not have the level of commitment from the entire team during this time.”

“Hallin is particularly proud of the outcome of this challenging project,” says Phil Chamberlain, Hallin‘s Director – Service Delivery.  “The team worked closely with the client to assess the situation before planning and executing the work safely and effectively.  All parties are very pleased with the outcome.”
