Overview
Boskalis Westminster is a UK dredging and marine contracting company based in Fareham, Hampshire, described on its own site as one of the UK's leading dredging contractors. Founded in 1933, it provides dredging and marine construction services including maintenance and capital dredging, land reclamation and coastal engineering, and is a subsidiary of the Dutch dredging group Boskalis.
History
Boskalis Westminster traces its origins to 1933, when the company was founded; its own site states it is one of the most experienced dredging and marine contracting companies in the UK. The company's history page describes the period from 2000 onwards as one of continued expansion of Westminster Dredging from its Fareham base and renewal of much of its dredging fleet, with major projects secured throughout the UK and Ireland including land reclamations as part of the expansion of the Port of Felixstowe, the deepening of the approach channels to Southampton and Portsmouth, and the Newbiggin coastal protection scheme. Following the Boskalis acquisition of SMIT Internationale in 2012, Westminster Dredging was rebranded as Boskalis Westminster Ltd. to reflect the increased capabilities of the group, which now includes Boskalis Marine Services, managing 14 vessels on behalf of the MoD to deliver training and range safety services around the UK coast; at this time the company's Mersey operations moved from Eastham to Liverpool. Between 1980 and 2000, regional offices were closed in 1982, centralising the company at James Yard, Southampton with responsibility for the UK and Ireland only, retaining only the 'Green Hut' site office at Bromborough; the company moved to Dukes Keep in central Southampton during 1984 and to its present location at Westminster House, Fareham in 1991, where the first major contract procured was the deepening and maintenance of the channel to Barrow-in-Furness to allow for the exit of the Royal Navy's Vanguard class submarines, while the Bromborough office moved to Eastham.
