ST Marine Support Acquired by Herman Senior BV

Netherlands-based tug & workboat company Herman Senior BV has acquired all shares of ST Marine Support, a provider of quality maritime and offshore services. The acquisition includes ST’s three existing vessels and their upcoming newbuild, a Damen Multi Cat 3313SD, which is expected to be delivered at the end of March this year. With the formal handover completed on 23 February, the acquisition has come into effect retroactively as of 1 January 2023.

With this agreement ST Marine Support becomes part of the Herman Senior group of companies, integrating both fleets. Erwin van Dodewaard, Commercial Manager and Co-owner of Herman Sr says: “We are proud to have been given the opportunity to acquire ST Marine Support by owners Vasco Tammes and Rienk Switijnk. Knowing each other quite well, we got into informal talks about 13 months ago, over a beer. Vasco and Rienk have built a great company over the years with three robust and strong Multicat workboats that operate at the top of their market segments, especially in Dredging. They and their team have a lot of experience and their clear, no-nonsense way of handling projects aligns neatly with our own way of working. We feel proud to continue their legacy under the Herman Senior flag. This acquisition is a big move forward for our company and quite a special step for our family. We look forward to welcoming the new boats and their crew into our fleet and serving customers with them.”

This acquisition marks the expansion of Herman Senior’s fleet from 8 to 12 vessels, including the new Damen Multi Cat 3313SD currently under construction. The expanded company will serve customers on three continents – South America, Europe and Asia – and these 4 extra workboats strengthen its presence both there and in the wider in the maritime industry.

All the vessels of both companies are Damen built Shoalbusters and Multicats. There is currently a shortage of workboats due to the large amount of projects that pull much of the available assets off the global market. At the same time, the cost of building new ships has skyrocketed, making the acquisition a very attractive option for increasing the size of the fleet.
