New Danish ferry M/S Hammershus leads the way with top technology
M/S Hammershus RoPax vessel sails smoothly in the Baltic Sea with Valmet’s DNA integrated automation system (IAS) covering the control, alarm and monitoring of machinery systems. With a capacity of 720 passengers including the crew and 90 freight trailers, M/S Hammershus is a modern RoPax vessel owned by the Danish ferry services company Molslinjen. The company operates ferry services between Jutland (Jylland) and the island of Zealand (Sjælland). The vessel was built in Finland by the Rauma Marine Constructions (RMC) shipyard, which specializes in multipurpose icebreakers, car and passenger ferries, and naval vessels. Telesilta, the Finnish marine electrical contracting company, integrated Valmet’s automation system with other systems on the vessel. As a result of the efficient work carried out by these three companies and their countless sub-suppliers involved in the project, the ferry is now sailing smoothly in the Baltic Sea.
