Norwegian Electric Systems (NES) has been awarded a contract by Green Yard Kleven to deliver energy design and smart control solutions for Rem Offshore’s new offshore wind vessel
The vessel, a construction service operation vessel (CSOV), will be the first in this market with a fully-integrated NES bridge system.
NES chief executive Geir Larsen said offshore wind vessels is an important sector for the company. “We offer shipowners forward-looking solutions which enhance safety and energy efficiency and have a reduced environmental footprint compared to the alternatives,” he said. “That is particularly important for an offshore wind vessel working in an industry that generates renewable energy.”
The CSOV for Rem Offshore is a ‘hybrid’ vessel for which NES, part of Norway’s Hav Group, will supply the design of the power and propulsion system, including a battery pack. The design will also include the potential to include a larger battery pack at a later date. Space has also been allocated for future installation of fuel cells.
“The battery pack means the ship can reduce its fuel consumption and CO2 emissions,” said Mr Larsen. “Our experience with comparable solutions shows the vessel could achieve savings of about 20% when operating with DP2 dynamic positioning mode.” He said further savings will also be possible when the vessel is berthed and from reduced maintenance requirements for the ship’s diesel engines.
The ship is being designed for installation of a 10-MW battery that will enable it to operate with zero emissions when operating in an offshore windfarm. This pack will also be capable of being charged via a buoy once the infrastructure is in place.
The vessel will also be fitted with NES’ RAVEN integrated navigation system (INS). The company says the INS is the first type-approved bridge solution based on an integrated computer system, rather than being put together from different software components.
The Raven INS is also designed to be monitored remotely. NES sales manager Svein Ove Farstad said this will provide the owner with insight into energy consumption and provide the basis for more energy-efficient operation which, in turn, will also reduce the ship’s environmental footprint and operating costs.
Rem Offshore technical and purchasing manager Ronny Pål Kvalsvik said the system will give the company the ability to incorporate new functionality as technology continues to develop.
