SEPTEMBER 17, 2015 — Five pilot projects will be pursued as part of Norway's Green Coastal Shipping Program, which aims to encourage the research and implementation of green technology concepts in the country's shipping sector.

The program was launched by DNV GL and now also involves 25 partners from the Norwegian maritime industry and the Norwegian authorities.

The pilot projects include several different ship types, and infrastructure with an emphasis on alternative fuel concepts.

"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," says Program Director Narve Mjøs.

CargoFerry plug-in hybrid: Shipping company Nor Lines will lead the first pilot project, CargoFerry Plug-in Hybrid, which aims to develop a cost-effective and profitable short-sea containership powered by a plug-in hybrid LNG/battery propulsion system. It is a short-sea containership 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.

Next-generation green shuttle tanker: Teekay Tankers will lead the second pilot project, which will investigate technical solutions for utilizing 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 optimize 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 utilizing VOC (volatile organic compounds) produced on board by capturing and condensing the recoverable gases produced during offshore loading. Using the liquid VOC for onboard power generation could reduce total fuel consumption and the environmental impact of the vessel. As VOC are generated during offshore loading, using them as an energy source could offer an additional environmental benefit to reduction in total demand for fuel.

Hybrid ocean farming vessel: The third pilot project, by ABB and the Cargo Freighters' Association, aims to define an optimized hybrid propulsion system for more energy efficient operations with greater redundancy.

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 and charging stations for plug-in hybrid ships.

Risavika Harbor 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.
