Offshore wind farm, Walney

Windfarm construction projects regularly feature in the work programmes of SMIT’s sheerlegs fleet. For example, the Taklift 7 was involved in the Walney Offshore Windfarm development in the Irish Sea. Walney Offshore is a wind farm project developed by DONG in the Irish Sea, some 20 miles from the coast at Barrow.

The first half of the development, Walney 1, became fully operational in 2011. SMIT’s scope of work involved the installation of a series of 51 large monopiles for Walney 1. The 1,200 tonnes lift capacity sheerlegs Taklift 7 was mobilized for the project, together with the multipurpose vessel Smit Buffalo, which provided support services. The main task was to upend the monopiles and hand over the structures to a jack-up installation platform. The monopiles were transported to Barrow by a coastal vessel, having been loaded in Poland. A shore crane discharged the monopiles as they arrived, they were then plugged and towed out to the windfarm installation site. Taklift 7 would then connect and bring each pile into the vertical position, ready for installation by the jack-up Goliath. Each pile had a length of 58 metres and a weight of around 600 tonnes during upending. This project involved around five months of work and was successfully completed in September 2010.

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.
