Thai Oil Public Company Limited is the largest petroleum oil refiner and supplier in Thailand. To enable Very Large Crude Carriers (VLCC) up to 320,000 DWT or a freight capacity of up to two million barrels to berth at Thai Oil's refinery in Sri Racha, Chonburi Province, a second Single Buoy Mooring (SBM) facility was installed approximately 14 km offshore, in water depths of around 30 m. From this buoy, a 52' diameter concrete coated steel pipeline had to be installed to the landfall location near the Thai Oil refinery.
Boskalis Offshore and Tideway formed a Joint Venture, which was awarded the contract for the pre-trenching and backfilling works. Boskalis Offshore provided the main equipment for the execution of the project. The landfall point of the pipeline was located within the Thai Oil refinery premises and the pipeline route was designed to run close to operational jetties. Because of the JV's flexibility during project execution and extensive consultation with Thai Oil, interference of the daily operations at the refinery and jetties was kept to an acceptable minimum.
