Karstensens Shipyard will build a new 83.00 m Pelagic Purser/Trawler ‘ROGNE’ for Norwegian fishing company Rogne AS

#482 – “ROGNE”

The shipping company Rogne AS has ordered a new 83.00 m combined purser/trawler from Karstensens Shipyard A/S.

The shipping company was established by Bjarte Rogne in 1965, and somewhat later his brother Marvin Rogne came in as co-owner. Today, the shipping company is managed by the next generation; Frank, Kjell-Ove and Per-Magne Rogne. They are all active with a long service life in the shipping company, and they currently operate “Rogne” as skippers and mates.

The current “Rogne” was taken over by the Shipping Company as a new building (KS-422 from Karstensens Shipyard) in April 2013. This vessel has proven to be highly efficient and at the same time economical.

The shipping company is well structured with quotas, and operates with combined trawl and purse seine fishing, where the trawl fishery consists primarily of blue whiting (Norwegian: Kolmule) fishing west of Ireland. Other fishing for primarily herring and mackerel is conducted with purse seines. The new vessel will be operated according to the same principles.

The outlook and the positive results of recent years made it a natural choice to invest in new construction.

The good experiences from today’s “Rogne” have made it natural for the shipping company to build at Karstensens Shipyard again.

Karstensens Shipyard is humbled and happy about the loyalty and trust Rogne AS shows by contracting another new ship in Skagen.

Design, interior design and events have thus been created in a very close collaboration between Rederi and Værft. The shipping company has been preoccupied with innovative and optimized solutions, based on the very positive operation of the current “Rogne” in recent years. It has been the Company’s power to have full influence throughout the design phase, so that the project will be tailored exactly to the wishes and requirements that the Shipping Company has.

Safety and working conditions for the crew are especially taken into account by the fact that “Rogne” will have the entire loading deck as waterproof. Further, the trawl deck aft is raised an entire floor, with the aim of increasing the freeboard and, consequently, safety.

In addition to this, great attention has been paid to the design of the hull and optimisation in relation to the operating profile of the “Rogne”, bearing in mind the lowest possible fuel consumption. In addition, the vessel is equipped with heat recovery from all engines as well as a number of other measures to ensure low possible energy consumption.

Like the other pelagic vessels that the shipyard has under construction for shipowners in Iceland, Norway, Sweden and Denmark, new “Rogne” are also of their own design.

A number of suppliers are currently selected, all based on criteria such as sustainability, energy optimization, innovation, quality and reliability.

The winch plant has already been contracted at Karmøy Winch, The hydraulic system has been proven and provides great reliability.

As on the current “Rogne”, on the new ship there will also be a large contribution from Norwegian suppliers, thus all machinery is supplied by Bergen Engines and Nogva.

The complete propulsion plant has been carefully assessed and calculated on the basis of the exact operating profile of the Shipping Company. In accordance with the desire to carry out a sustainable fishery with minimal NOX/CO2 emissions per kg of fish caught, the fall has been chosen on a fuel-optimised plant package with 2 main engines each of 3600 kW. By far the largest part of the operating time, the ship will be powered by one engine, which will thereby operate in an optimal area.

As part of the propulsion system, the propeller system is optimized for the operating pattern, where most (about 80%) of the time is free-sailing, with a large, single propeller with diameter of 4500 mm.
