Norway Studies Green Coastal Shipping for the Future from Electric Ferries to LNG Carriers

Five Pilot Projects Launched
Shipping News Feature

NORWAY – Class society DNV GL and its partners from the Norwegian authorities and the local maritime industry have presented the five pilot projects that will be pursued as part of the Norway’s Green Coastal Shipping Programme, which, having launched at the beginning of the year, aims to encourage the research and implementation of green technology concepts in the country’s shipping sector. The five pilot projects selected include several different ship types, and infrastructure with an emphasis on alternative fuel concepts. Programme Director Narve Mjøs, said:

"When we launched the Green Coastal Shipping Programme, we said we wanted to make Norway a world showcase for green coastal shipping. With these five pioneering pilot projects we are well on our way.”

CargoFerry plug-in hybrid

The first pilot project, CargoFerry Plug-in Hybrid, aims to develop a cost-effective and profitable short-sea container ship that is powered by a plug-in hybrid LNG/battery propulsion system. It is a short-sea container ship concept with a zero-emission solution during port sailing and operations. After developing the technical concept, the project partners will calculate the vessel’s environmental footprint and carry out a cost/benefit analysis. The shipping company Nor Lines will take the lead on this project.

Next-generation green shuttle tanker

Teekay Tankers will lead the second pilot project, which will investigate technical solutions for utilising batteries and VOC (Volatile Organic Compounds) in a shuttle tanker. Battery technology has not been used on this vessel type yet and the project will explore how it could potentially help to optimise operations and reduce the need for installed power. The project partners will also look at the possible use of batteries as a ‘spinning reserve’.

After assessing the economic and regulatory feasibility of battery-powered shuttle tankers, the project will review new technological solutions for utilising VOCs produced on board. VOCs are utilised by capturing and condensing the recoverable gases produced during offshore loading. Using the liquid VOC for on board power generation could reduce total fuel consumption and the environmental impact of the vessel. VOC is an energy source which, by its consumption, could potentially offer an environmental benefit in addition to reducing the total demand for fuel.

Hybrid ocean farming vessel

The objective of the third pilot project is to define an optimised hybrid propulsion system for more energy efficient operations the project owners being ABB and the Cargo Freighters’ Association.

Conversion of cargo carrier into battery-hybrid LNG carrier

This project aims to develop a cost-efficient LNG distribution concept with a hybrid LNG/battery propulsion solution and zero-emission port operations. Converting an existing vessel may provide a cost-effective option for small LNG carriers. The project owners Øytank Bunkerservice and the Norwegian Gas Association will lead the way in developing the technical concept, calculating the environmental footprint and carrying out a cost/benefit analysis.

Pioneering green port project

The fifth pilot project has the objective of developing a low-energy-consumption port with a minimal carbon footprint. Some of the technologies being employed to achieve this include electric heavy-duty vehicles and cranes. The green port will also be equipped with smart gates, offer cold ironing services (provision of alternative maritime power whilst a ship is docked) and charging stations for plug-in hybrid ships.

Risavika Harbour in Stavanger will take the lead in the green port project, developing the technical concept, undertaking a cost/benefit analysis, calculating the environmental footprint and presenting a plan for further development of the concept.
