Pipeline crossing, Strait of Magellan

The project involved the construction of a new, strategically important, 24" natural gas pipeline across the Strait of Magellan, linking Cabo Espíritu Santo in Tierra del Fuego province with Cabo Vírgenes in Santa Cruz province. The new pipeline was built as an expansion of the existing San Martín pipeline in an effort by the government to increase gas supplies from Tierra del Fuego to the Argentinian mainland.

The new submarine pipeline runs parallel 50 meters west of the existing pipeline that was built in 1978. The link was the final piece of a significant onshore project involving the construction of a pipeline stretching thousands of kilometers to carry the gas recovered from fields in the south to the distribution network in the north. The ‘Gasoducto Transmagallánico’, as the pipeline is called in Argentina, will transport 18 million m3 of gas a day. Boskalis Offshore’s scope consisted of pre-trenching both shore approaches, pipeline pull-in and pull-out at the landfalls, submarine tie-in, hydrotesting and backfilling of the trenches. The multidisciplinary project has been completed in eight months after contract award, which is exceptionally fast considering the remote location, limited infrastructure, lack of local facilities and complexity of the project. Weather conditions in the Strait of Magellan can be notoriously severe. The harsh local conditions feature rapid weather changes, storms, strong currents and a tidal range of more than ten meters.

Pipeline survey and freespan correction, Bach Ho

The Bach Ho Gas Pipeline is located at the South Coast of Vietnam in the province of Vung Tau and comprises a 16" pipeline installed in 1994. The 16" pipeline is one of the main production lines of Petrovietnam Gas Company (PVGAS) and important for the supply of natural gas to electrical power plants, production and export of LPG and other domestic users.

Gas pipeline project, Trans Thailand Malaysia

The Trans Thailand Malaysia Gas Pipeline Project comprised the installation of a 34 inch concrete coated gas pipeline, running from the joint Thai-Malaysia development area approximately 270 kilometers offshore towards the southern Thai coast near Chana. As part of this project a contract was awarded to the Boskalis Offshore B.V. - Tideway B.V. consortium for the provision of the dredging and backfilling works, whereas Boskalis Offshore provided the main equipment and project support.

Shore approach and landfall works, Libyan gas transmission system

West Libya aimed to enhance its position in the supply of continental Europe's energy needs. As the demand for cleaner energy was rising and gas consumption in Italy wasexpected to increase, Libya and Italy found common ground for cooperation. Construction of a 700 million USD gas treatment plant in Mellitah was the centrepiece of this West Libya gas project. The Mellitah plant is supplied with gas from the desert Wafa field, 520 kilometers south-west of Tripoli, and from the offshore Bahr Essalam field, 110 kilometers north of Tripoli.

Dredging and backfilling, TSEP

In order to increase the production capacity from the gas condensate fields located off the North West Coast of Western Australia, Woodside Energy Limited, on behalf of the North West Shelf JV Participants, has realized the installation of a multiphase subsea 42" pipeline. The new trunkline supplements an existing 40" pipeline, which conveys gas/condensate from the North West Shelf fields - North Rankin, Goodwyn and Cossack/Wanaea - to onshore treatment facilities located on the Burrup Peninsula near Dampier, Western Australia.
