Hallin completes survey and subsea repair offshore ThailandProjects and Operations // February 28, 2014
Hallin Marine recently completed a 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 Hallinís subsea a vessel 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 unravelling 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.
