Over the past century Boskalis has grown from a local Dutch Sliedrecht-based dredging company into a global market leader in the field of dredging and inland infra, offshore energy, and towage and salvage. Some highlights include playing a major role in the Dutch Delta Works in 1953, going public in 1971 and receiving the designation ‘Royal’ in 1978, our involvement in ground-breaking international projects such as the Øresund tunnel and construction of Hong Kong international airport in the 1990s. In 2013 we expended our offshore activities with the aquesition of Dockwise and in 2014 with Fairmount Marine, and more recently, in 2021 Boskalis acquires all shares of Rever Offshore’s subsea services business (‘Rever’). Rever, formally known as Bibby Offshore.


As of April 2018, Dockwise, VBMS and Fairmount continue to offer their services under the brand name Boskalis. This name change follows the decision by Boskalis to merge all of its activities under a single brand name in the course of 2018 to combine knowledge, strength and expertise in the provision of heavy marine transportation, offshore installation and onshore logistical management. In August 2017 we added marine geophysical surveys, offshore geotechnical services and environmental surveys to our activities, with the acquisition of subsea survey specialist Gardline. This fulfils our strategic ambition to build a position in the offshore survey market to become a specialist provider of subsea geotechnical surveys with an exposure to the renewables market and the early cyclical oil and gas market.
