L10 -C -D & -G Decommissioning

Neptune Energy Netherlands B.V. (Neptune) has awarded Boskalis the contract for the removal, transport and load-in of three platforms. These platforms are located in the Dutch North Sea, approximately 90 km west of Terschelling.

The platforms are situated in the L10 field and are named L10-C, L10-D and L10-G. Water depth at the various locations is approximately 26 m. The topsides weighed around 500 tons and the jackets approximately 600 tons. Contractor scope of work is the removal, transport to the dismantling site at Flushing and subsequently offloading to the quayside of three offshore platforms.

During the project execution the world faced the COVID-19 pandemic. With combat plans in hand the project was safely executed safeguarding the health of the complete crew.

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.

Glory hole excavation, White Rose

The White Rose offshore oil field is the third major oil field in the Jeanne d’Arc Basin on the Grand Banks, some 350 kilometers east of St. John’s, Newfoundland, Canada and within 50 kilometers from the Terra Nova and Hibernia fields. The South White Rose oil pool covers approximately 40 square kilometers and contains an estimated 200-250 million barrels of recoverable oil.

Development gas export pipeline,
Hibiscus to Point Fortin

The NCMA Development Project comprised the development of the North Coast Marine Area, which is located in the Caribbean Sea and Bay of Paria, Trinidad. The project included the installation of a 24" Gas Export Pipeline from the Hibiscus Platform to a landfall at Point Fortin. From the landfall the pipeline was routed by directional drilling and by surface laid pipeline, to a termination point in the Atlantic LNG Terminal at Point Fortin. As part of this project Boskalis was awarded the contract for the provision of landfall, directional drilling and onshore pipeline installation and testing of the 24" gas pipeline system.

Re-insulation Gannet 'C' Bundles, North Sea

The Gannet 'C' satellite field, which is located in the North Sea at 112 miles East of Aberdeen in 95-meter water depth, comprises four drill centres, each having one or more producing wells. The drill centres are connected to the local platform Gannet 'A' by four flowline bundles with a total length of 10 kilometers. A glycol-based gel, filling the annulus of the Gannet 'C' carrier pipe, insulated the individual flow lines. Prompted by degradation of the gel and the resulting drop in oil and gas arrival temperatures at the platform, an EPIC project took off for a re-insulation system. The objective of the re-insulation system was that it should provide sufficient insulation to the bundles in order to safeguard production during the total field life of Gannet 'C', being a minimum lifetime of 15 years. Boskalis Offshore was supported by Hydronamic - the in-house engineering department.
