The aquaculture industry is looking for a greener profile. Electrification of the growing fleet of workboats is now underway.
Salmar Farming is first out and ordering a 13.5 meter long and 7.5 meter wide catamaran which should have battery operation.
Siemens is in the final stages of dimensioning the battery pack and the electrical system.
Freya yard Ørnli Release with 22 employees based expertise in a field yard think will grow much.
Building skills
– There are a lot of replacement of working methods and fish farming is expanding. We are pleased to be ahead and build expertise in the electrification of the vessels, says Torstein Yttersian, general manager of Ørnli release.
Work boat:
- 13.48 meters long, 7.6 meters wide.
- Build in aluminum.
- Smooth deck catamaran.
- Propulsion System: Blue Drive PlusC from Siemens, previously used in the world’s first electric fish fishing boat and the electric car ferry Ampere.
Work boat to Salmar based on a vessel type Ørnli has delivered many. Normally delivers yard four such aluminum boats a year.
– We have taken based on an existing design and builds on and modifies for electric propulsion, says Yttersian.
Emergency
in addition to the battery pack, it delivered a diesel-powered emergency generator of 160 kWh, big enough to get the boat home from the cages.
the vessel will have 30 minute transit and then be looking at the cages all day and return when leaving work.
the ship will not DP (dynamic positioning), but using baugthrustere and propellers remain in position for some time, depending on weather and power.
known and proven
Technical manager in Salmar Farming AS, Eskil Bekken, saying that they are going for a known technology, although there first with an electric workboat.
– We have chosen proven solutions that Siemens has delivered to both electric ferries and large ships. Now that we can save the environment and improve working conditions for the staff gets very exciting, says Bekken.
– Now it’s finally aquaculture turn to be electrified, and now we do it with technology that is proven offshore, says chief technology officer of Salmar Farming aS, Eskil Bekken.
Trøndersk pride
Siemens has supplied battery packs and electric system to Ampere, the world’s first large battery ferry, and to a fishing smack. In addition, the company has gained a lot of experience with hybrid offshore ships.
The workhorse for Salmar get a battery of 200 kW / h with two propellers for propulsion, each of 160 kW / h.
– the vessel will also get electric tunnel and some other ancillary electrically to ensure the highest possible energy efficiency, says Odd Moen, sales director at Siemens Marine.
He finds it gratifying to be part of make aquaculture greener.
– we are proud that the technical solutions that we have developed at Siemens in Trondheim now getting stick in a new segment where Norway has a leading position in the world. This is in addition an important step to reduce greenhouse gas emissions for vessels in the farming industry, says Moen.
Electric ambitions
Enova has given two million in aid to the world first electric workboat to the industry. Enova is pleased that several farming sectors replacing diesel generators on the shore of including barges.
Enova transport Marketing Petter Hersleth’m excited about the pilot project’s potential impacts.
– an electric hybrids plug-in a fish farming that can charge from shore power plants on barges represents something completely new, and if Salmar succeed, it can have huge repercussions in the industry. We are pleased that SalMar go ahead and show how industry can cut down on use of fossil fuels, and is proud to contribute to this ambitious project now being realized, says Hersleth.
Environment Cheers
With ambitions to grow 5-6 times during the next few years must also seafood industries do their best to meet Norway’s obligations on emissions, says a senior advisor Kjetil Paulsen Bellona.
– This solution represents an important step in the right direction.
The operating schedule to work the boats are great for battery operation and this solution contributes to both improved working environment and reducing greenhouse gas emissions. We hope that this project will be an inspiration to several breeders and suppliers so that both working vessels and aquaculture rafts eventually becomes zero emission, said Paulsen to TU.
More retrieving
Bellona notes that seafood industry also faces major challenges on the transport side. Transfer to the sea and the use of more environmentally friendly propulsion technology can help the industry to better environmental profile.
-Today runs large parts of Norwegian seafood exports by car and new solutions that allow maritime transport are competitive both in price and delivery time will be absolutely necessary to achieve the objectives of reduced emissions and sustainability.
