The NSK 6480, Sefine NB71 is a hybrid Light Construction Support Vessel (CSV) designed for light construction work, inspection and repair as well as offering a flexible platform for support operations in the ocean windfarm industry both in field development and service in operation. The support operations can include Walk-to-Work (W2W), power cable pull in and commissioning, power cable protection installation, maintenance, inspections, top side lifting for windmill and OSS with 3D compensated crane, ROV services and others. The CSV is a dual fuel diesel/methanol electric driven vessel with optional battery package for safe, environmental and economic operation.

The accommodation is tailored for 100 persons.

The vessel has a 150 T AHC crane with 3D topside lifting capability and dual integrated ROV systems for 6000 m operational depth.

The CSV is a dual fuel diesel/methanol electric driven vessel with optimised battery package for safe, environmental and economic operation. 

During flexible operational profile the vessel will have a reduction of ~75 % of CO2 emissions.

The first vessel is under construction at Sefine Shipyard in Turkey.

Main Characteristics

 The 1200 m3 live fish carrier concept is designed for transportation of fish in shallow waters with an hybrid diesel electric propulsion for optimum performance and fuel efficiency. The vessel is prepared for future delousing equipment installations on weather deck.

 Main Characteristics

The 2200 m3 live fish carrier concept is designed for transportation and freshwater treatment. The design is equipped with a diesel mechanical propulsion system for optimum performance and fuel efficiency in transit voyages. A fresh water production system of 5000 m3/day capacity is installed.

The vessel is under construction at Zamakona Shipyards, Spain.

Main Characteristics

The 4300 m3 LNG hybride live fish carrier is developed especially for offshore fish farming with emphasis on reduction of the environmental footprints and fuel costs.

The design is equipped with an LNG electrical propulsion system and battery package for optimum performance and capability during offshore fish handling and delousing operations.

The vessel is equipped with multiple systems for gentle delousing of fish including a fresh water production system.

The ship is constructed at Tersan Shipyard, Turkey.

Main Characteristics

The LNG hybrid fish pellets carrier is developed for optimum efficiency with emphasis on reduction of the environmental footprints and fuel costs.

The vessel is designed with DP capability for pellets discharge. This enable “handsfree” fish feed delivery without the need for mooring at the feed barges.

The cargo hold is subdivided in multiple silos for transport of a variety of different pellets types. The vessel also have a closed cargo hold for transport of fish feed in big bags. A separate cargo hold has arrangement and capacity for carrying containers and containers may also be carried on deck. The vessel has a cargo crane with capacity of 50 t SWL.

The fish pellets carrier is equipped with automatic pellets discharge system that does not require manual operations. For delivery to standard fish pellets barges, discharge crane at starboard side is applied. The vessel also has a dense phase blowing system enabling deliveries from the bow.  

The design is equipped with an LNG hybrid propulsion system and battery package for optimum performance and capability during offshore fish feed transfer. 

The ship is constructed at Tersan Shipyard, Turkey.

The next generation of this vessel will be optimized for fish feed transfer to offshore fish farms, as well as further improvement of environmentalt footprint.

The LNG hybrid fish pellets carrier is developed for optimum efficiency with emphasis on reduction of the environmental footprints and fuel costs.

The vessel is designed with DP capability for pellets discharge. This enable “handsfree” fish feed delivery without the need for mooring at the feed barges.

The vessel have three cargo holds for flexible access and separation of multiple feed types. The feed is transported in big bags. The big bags are transported internally in each cargo hold by using fork lifts. The vessel has a cargo crane with capacity of 50 t SWL.

The loading system of this vessel is a side gate and a flexible elevator giving access to all three cargo decks. 

The discharging crane system has a reach of 25 m.

Main Characteristics

Capacity

FjordMAX concept is a semi-closed fishfarming unit for fjords and benign waters. The unit integrates collection of sludge from feed spill and fèces with facilities for pumping this in to the FjordMAX for drying and transportation to shore. The unit has grossly reduced the risk of fish escape through the integrated secondary barrier net system. The unit has a high volume oxygen rich seawater injection system pumping seawater from 60 m depth into the production nets. In addition the unit has it’s own O2 production facilities with amble capacity according to the production needs.

Main Characteristics

Capacities

The Havfarm unit is a weather vaning turret moored fish farm. The unit has integrated  fish feed silos and a robust water injection system optimising the oxygen level inside the net pens. The unit is dimensioned for a wave height of 10 m Hs. The unit has protective steel skirts reducing current effects inside the fish pens and together with overpressure from water injection system keeping sea lice outside the unit.

The weather vaning motion of the Havfarm increases the area where fèases and feed spill will spread, and by this eliminate the fallow time due to seabed conditions. The weather vaning motion also reduce all weather induced loads as the unit will always have the heading with the least loads.

The unit is self sustained and independent of service vessels by use of the RMSU (Rail Mounted Service Units) and the semi automatic integrated live fish transfer system. The tailored NSK Ship Design Live fish carriers with DP systems and live fish transfer system are optimised for the new generation of exposed fish farms.

The above minimise the risk of cross contamination from frequent use of service vessels visiting several fish farming locations and potentially spreading diseases.
