Karstensen Shipyard Delivers “HÁKON” to Icelandic Owners Gjögur p/f

On 10 October 2024, Karstensen Shipyard delivered Newbuilding 475, a 75.40 m Purser/Trawler named “Hákon,” to Icelandic owners Gjögur p/f.

The hull for Hákon was constructed by Karstensen Shipyard Poland in Gdansk. This new vessel replaces the owner’s previous vessel of the same name, which is now up for sale. Gjögur p/f also operates two additional demersal fishing vessels.

The vessel’s design, specifications, and arrangements are the result of close collaboration between Gjögur p/f and Karstensen Shipyard, with all solutions custom-tailored to meet the owner’s and crew’s specific needs.

The primary focus was on optimising working conditions, crew safety, comfort, catch handling and storage facilities, and fuel efficiency. To achieve these goals, Hákon is equipped with the latest machinery and technology. Karstensen Shipyard has another sister vessel in production for Skinney-Thinganes, another Icelandic client.

Hákon’s hull is made of steel with two continuous decks, featuring long forecastle and boat decks. The wheelhouse, boat decks, funnel, and masts are constructed from aluminium. The hull design is round bilge with a bulbous bow and stern skeg, vertical wave-piercing stem, and a transom stern. Below the main deck, the hull includes watertight compartments such as the forepeak, sonar/thruster room, insulated RSW tank section with 13 tanks, a central RSW pump and manifold room, engine room, and an aftpeak with fuel and lubricant oil tanks.

On the main deck, the vessel has forepeak storage, an ozone plant room, and a central RSW hold with corridors leading to a vacuum pump room, RSW machinery room, and midship engine workshop. Accommodation includes crew cabins, each with en-suite facilities, laundry, trim room, stairs, and corridors, designed to minimise noise by being located far from the propeller.

The shelter deck features storage rooms, a generator room, and an enclosed loading deck with an RSW control room, scales, and a water separator. A full-width superstructure includes five crew cabins and a hospital room with en-suite facilities, along with changing rooms and a coffee bar. Abaft the superstructure, the trawl deck includes net drums, a hydraulic stern gate, and guiding pins. The boat deck hosts mooring equipment, a purse seine deck with winches, cranes, and fish pump facilities. Additional features include a galley with provision rooms, a mess room, a cinema/TV room, and fan rooms for ventilation.

The main engine, a Wartsila 8V31 producing 5200 kW, is connected to a reduction gearbox and a ducted propeller. The vessel’s electrical system includes a shaft alternator generating 3000 kWe, supported by two auxiliary engines from Caterpillar, producing 940 and 565 kWe respectively. The vessel’s power management is controlled by a DEIF Power-Management System, allowing flexible power allocation between the main engine, thrusters, and other systems. An emergency take-me-home function enables the shaft alternator to operate as an electric propulsion motor in case of engine failure.

Hákon is outfitted with an extensive array of hydraulic winches and fish pumps from SeaQuest of Killybegs, Ireland, including two 91-ton trawl winches, a 40-ton purse winch, and various mooring and anchor winches. Fish handling equipment includes hose reels, fish pumps, a 20-inch SeaQuest hydraulic fish pump, and associated hydraulic systems with multiple pump units.

The wheelhouse on the Hákon fishing vessel is designed to provide optimal visibility and operational control for the crew, situated atop the vessel’s deckhouse. This area offers a full 360° view, crucial for navigation and monitoring activities.

The wheelhouse is equipped with advanced navigation and control systems, including consoles provided by El-Pro of Norway, and features Nor-Sap 1600 chairs for comfort during extended periods of operation. Additionally, the layout and technology in the wheelhouse are tailored to ensure seamless integration with the vessel’s extensive electronic systems, such as radar, sonar, autopilot, and other key navigational aids supplied by leading manufacturers like Simrad and JRC.

The wheelhouse also incorporates a display system with 21 Hatteland monitors (32″, 27″, and 24″ sizes) for enhanced situational awareness, linked to a Sónar monitor matrix system for centralised data access. This setup allows the crew to monitor sonar, radar, GPS, and autopilot systems, providing critical real-time information for vessel management and safe operation.

Designed with functionality and safety in mind, the wheelhouse on the Hákon represents a state-of-the-art command center, ensuring the crew can navigate efficiently while maintaining full control of the vessel’s systems​.
