Acta Marine is the result of a successful merger between shipping company Waterweg and Van Stee. The merger produced a remarkable and powerful mix of experience, knowledge and workboats. It has established an impressive foundation from which the company aims to achieve its ambition: further growth as a worldwide, leading operator of coastal and shallow draft workboats.
Although Acta Marine was founded in 2005 through the combination of the shipping company Waterweg and Van Stee Survey & Supply, the maritime experience of the merged companies dates back to 1970. This experience contributes to Acta Marine’s position as a prominent player in the area of coastal and shallow waters.
Shipping company Waterweg was established by vessel builder Henk de Haas in 1970. He was only 22 years old when he decided to empower his vision: to operate Tugs build on the family yard. In the mid-80s he completely turned his attention to the shipping activities, resulting in a rapid development of the company. In that period many towing and salvage operations were executed. The vessels were increasingly operated for projects in the Dredging & Marine Construction industry. It was not long before the company expanded to the Asian and African markets, where it proved itself a reliable and flexible partner in large and smaller projects. Its growth, take-overs, and the expansion of the fleet made it possible to carry out offshore Oil & Gas projects in coastal waters. The company also expanded its activities with (remedial) burial of cables and pipelines in shallow waters.
Van Stee was founded in Harlingen by the eponymous Rinus van Stee, in 1975. After years of working in fishing, Van Stee decided to operate Sara Maatje I, a small shallow water Tug. Shortly after, the fleet was expanded with a number of vessels and the company changed its course, now fully focusing on shallow water operations. The opportunities offered by the offshore Oil & Gas industry did not stay unnoticed and the company acted accordingly. As a result, it rapidly increased in size and reputation and became active in many offshore projects at home and abroad.
Waterweg and Van Stee joined forces within the Acta Marine Group in 2005. During the first years after this merger, both companies kept their old names. It was not until 2010 that the two companies were fully merged and the company name Acta Marine was adopted.
Acta Marine introduced its innovative Dynamic Positioning system in 2009. It was first used on a Shallow Draft Multicat. In the same year the Coastal Discovery was launched: the first DP Multicat in the maritime industry. The company further expanded its fleet with four Shoalbuster Anchor Handling Tugs, supplied by Damen Shipyards Group in 2012.
