North Sea Ro-Ro to be fitted with tiltable rotor sails

Norsepower has reached an agreement with SEA-CARGO to install two ‘tiltable’ 35-metre high Rotor Sails on board the SC Connector, a sidedoor Ro-Ro opertating in the North Sea.

Norsepower said that the SC Connector’s North Sea location ‘allows for some of the most favourable wind conditions for Rotor Sails’, but the vessel’s routes ‘involve navigating under multiple bridges and powerlines which require the Rotor Sails to have a tilting function’.

The SC Connector’s Rotor Sails, added Norsepower, can ‘tilt to almost horizontal when required’.

The Norsepower Rotor Sail Solution – which can be installed on new vessels or retrofitted on existing ships – is a modernised version of the Flettner rotor, a spinning cylinder that uses the Magnus effect to harness wind power to thrust a ship.

Preparations for the retrofit on the SC Connector are currently taking place with the installation scheduled for Q4 2020.

Norsepower said the Rotor Sails will reduce the SC Connector’s emissions by an estimated 25%.

Commenting on the agreement, Tuomas Riski, CEO, Norsepower, said: ‘We are delighted to be working with SEA-CARGO, not only as they are keen to demonstrate their commitment to maximising the propulsive power of wind to reduce emissions, but also for their cooperation and innovation in making tilting Rotor Sails a realisation. Rotor Sails are particularly well suited to Ro-Ro vessels and working with SEA-CARGO to deliver a tilting Rotor Sail ensures we are providing an adaptable solution which fits with particular vessel requirements, specifically demonstrating vessels with height restrictions to benefit from the Rotor Sail solution.’

Ole Sævild, Managing Director, SEA-CARGO, added: ‘With a growing international focus on reducing CO2 emissions and other gases/particles – the ability to harness wind to generate energy, reduce fuel consumption and emissions is a natural next step for the maritime transport industry. The goal of this project has been to design more environmentally friendly vessels by combining several existing technologies. In good wind conditions, the sailing hybrid vessel will maintain regular service speed by sail alone.’
