Hydroniq Coolers to equip newbuild wellboat. Norway-based Hydroniq Coolers has been contracted by Norwegian shipbuilder Fitjar Mekaniske Verksted to deliver its hull-integrated marine cooling system to a live fish carrier that is being built for North Salmon Service.
Hydroniq Coolers’ scope of supply includes a complete “Rack” seawater cooling system, which is integrated in the hull below the main engine room of the vessels, thereby freeing up valuable space in the engine room.
Marine cooling systems are utilised to reduce temperatures in the ship’s engines and other auxiliary systems through use of seawater to avoid overheating of the engine and other critical systems.
“This is a future-oriented live fish carrier design that is flexible and adaptable to alternative energy sources and includes a number of energy-reducing solutions. The latter is a key feature of our Rack seawater cooler too,” says Magnar Kvalheim, sales manager at Hydroniq Coolers.
For example, the Rack is equipped with fuel and energy saving solutions such as frequency operated seawater pumps which due to low pressure drop requires lower power consumption. Chilled water element reduces running time at the chilled-water compressors while heat recovery element makes it possible to use the surplus heat, further underlining the system’s energy efficiency.
The Rack system is also designed to increase intervals between each clean and reduce cleaning time when cleaning is necessary. It does not require dry-docking for maintenance as the coolers can be extracted from below the engine room, even while at sea.
“The crew can easily extract the system and clean it themselves. No external service technician is required. All such things contribute towards keeping vessel opex as low as possible,” adds Magnar Kvalheim.
Hydroniq Coolers will manufacture at assemble the Rack seawater coolers at its headquarters at Ellingsøy outside Aalesund, Norway. The company has not disclosed the value of the contract.
North Salmon Service’s newbuild live fish carrier is of HAV 595 design. It is equipped with hybrid propulsion – including variable-speed generator sets, DC distribution, and a large battery pack – which reduces energy consumption, increases operational flexibility, and paves the way for alternative energy sources.
The vessel will be constructed at Fitjar Mekaniske Verksted in Norway, with delivery scheduled for 2027.
Fitjar Mekaniske Verksted was established in 1957 and is located in Fitjar, south of Bergen. The shipbuilder specialises in wellboats, workboats and stun & bleed vessels, and delivers both designs, newbuilds and service. Vessels up to 50 meters are built complete at the shipyard, including hull work.
