The Dutch maritime service provider Royal Dirkzwager has been taken over by ProMedia Group, the mother company of RailFreight.com. This makes the restart of the company a fact. Royal Dirkzwager, which celebrated its 150th anniversary this year, went bankrupt at the beginning of September after parent company Ahrma Groep was declared bankrupt.

The maritime service provider from Maassluis has gone through major changes in recent years. Historically, the service primarily consisted of signaling and registration of approaching seagoing vessels. The portfolio has since been expanded with a variety of related products. Critical infrastructure in the North Sea, such as offshore installations, wind farms, cables and pipes, is monitored from the 24/7 control room.

In addition, an important function is the accurate checking and updating of maritime data via the Ship2Report platform. This is SAAS software for maritime ship movements and monitoring. The ship database contains over 200,000 ships and historical AIS data of more than 5 years.

Strategic choice

“The purchase of Dirkzwager and Ship2Report is a strategic choice for ProMedia. Current events show that securing critical offshore infrastructure cannot be taken for granted. This is a huge growth market and we will continue to expand Remote Offshore Asset Monitoring in the coming years”, said ProMedia CEO Joan Blaas.

Royal Dirkzwager’s customers include shipping companies, terminal operators, shipping agents, but also companies in the offshore sector and wind farms.


ProMedia Group is a fast-growing media company specialised in ports, transport and logistics. Well-known brands, apart from RailFreight.com, in the portfolio include Nieuwsblad Transport, Schuttevaer and Flows.

Blaas continues: “We already have maritime SAAS services via Mainport Mail and Port Departures, but that cannot be compared with the level of Royal Dirkzwager. The 24/7 control room ensures unprecedented data quality and that is unique. We want to seize the opportunities. We are going to invest in people and resources. In addition to 17 employees who are transferring, Royal Dirkzwager has six vacancies to strengthen the team. We are looking for Maritime Coordinators, Offshore specialists and Sales & Marketing people, among others.”
