Marine safety research draws on benefits of digitalisation and new technologies
broad range of experts met in Vantaa in November to discuss the Motorways of the Sea concept in the Baltic Sea ,
A new navigation technologies , leveraging of digitalisation and other current research in marine safety .
This international seminar , organised by the Finnish Transport Safety Agency ( Trafi ) and the Danish Maritime Authority , is connected with the EU ’ s Policy Area of Maritime Safety and Security under the EU Strategy for the Baltic Sea Region , in which Finland and Denmark are joint coordinators . The seminar focused on the results of recent projects of major importance for the Strategy , known as Flagship Projects .
“ We can see at this seminar that maritime safety research currently has a keen focus on digitalisation and how it might be leveraged , from a wide variety of perspectives ,” says Director Sanna Sonninen from Trafi .
The purpose of the seminar is to bring together researchers and maritime operators , to prompt discussion on research needs , and to promote awareness and availability of research findings at Finnish maritime enterprises .
“ We are pleased that the goals of the seminar were attained and that we were able to facilitate more widespread awareness of research in the field . We will continue to invest in maritime safety research both under the EU Strategy for the Baltic Sea Region and otherwise ,” says Sonninen .
The purpose of the EU ’ s Policy Area of Maritime Safety and Security ( PA Safe ) related to the EU Strategy for the Baltic Sea Region is to make the Baltic Sea a showcase for maritime safety and maritime security measures . n

Rolls-Royce To Deliver Propulsion for new Danish Passenger Ferry
Danish ferry operator Mols-Linien has ordered a new passenger ferry from the Rauma Marine Constructions yard in Rauma , Finland . Rolls-Royce will provide the main propellers and propulsion control system to the new ship , which is planned to operate between mainland Denmark and the island of Bornholm , also known as the sunshine island of the Baltic Sea .
Rolls-Royce will deliver two units of a Promas system which integrates the controllable pitch propeller , a propeller hub cap , a rudder with bulb and a twisted leading edge into one hydrodynamically optimized unit . Gearboxes , steering gears , two tunnel thrusters in the bow and a control system are also part of the delivery .
Gary Nutter , Rolls-Royce , Director Products , said : “ By adapting the propeller and rudder into one propulsive unit , Promas offers increased propulsive efficiency and improved manoeuvrability . It is chosen by both conventional single and twin screw ships , such as the passenger ferry to be constructed for Mols-Linien .”
Included in the order are cavitation tests at the Rolls-Royce Hydrodynamic Research Centre ( HRC ) in Kristinehamn , Sweden . At this advanced facility , the performance of the combined propeller and rudder system ( Promas ) will be controlled and tested prior to manufacturing . The HRC includes a large cavitation tunnel where a model of the ship ’ s hull , with the ordered propulsion set up , will perform in different operating conditions . Model testing can lead to important and cost-saving adjustments in a product or ship design .
Göran Grunditz , Rolls-Royce , Manager HRC , said : “ Cavitation tests are digitally documented and log efficiency , cavitation performance and risk of cavitation erosion on the equipment . The tests provide us , the yard and the owner with useful data related to estimated future fuel consumption and can also help the owner when planning for future services intervals .”
The Rolls-Royce Hydrodynamic Research Centre is one of the world ’ s leading marine research facilities , specialising in the development of marine propulsion systems including the design and testing of propellers and water jets .
The new passenger ferry for Mols-Linien will have a capacity of 600 people and two decks totalling 1,500 lane metres for transportation of cars and trailers . It is planned to enter operation in September 2018 . n seatec 1 / 2017 47
