The Cold Chain Starts at Sea

In today's seafood industry, freshness is non-negotiable. Processors, retailers, and end consumers demand high quality, and that starts the moment fish are brought onboard.

That's why more vessels are adopting slurry ice systems, like OptimICE®, to ensure consistent, sub-zero cooling from catch to consumer.

What Is a Slurry Ice System?

OptimICE® is a liquid slurry ice technology that replaces conventional flake ice and RSW. It produces a flowable ice mixture from seawater or saltwater, rapidly chilling fish to below 0°C / 32°F — typically reaching -0.5°C / 30.5°F within 2 hours — without freezing the product.

Unlike flake ice, which melts unevenly, or a dated RSW system that struggles to maintain uniform cooling, slurry ice surrounds each fish, delivering fast, even, and gentle chilling that preserves freshness and texture.

The result? An unbroken cold chain, from the deck to the dinner plate.

How It's Integrated Onboard

Here's how OptimICE® fits into modern vessel operations:

• Slurry Production Slurry ice is produced onboard using seawater or brine, chilled through a compact refrigeration system.
• Storage Tanks: The ice slurry is stored in insulated tanks with continuous agitation to maintain a uniform mixture, ensuring it is ready for immediate use.
• Distribution System Pumps and pipes carry the slurry directly to key points onboard — bleeding tanks, processing lines, and fish holds — ensuring fast and consistent chilling at every stage.
• Hands-Off Handling Because the slurry flows like water, it automatically surrounds the fish, reducing manual ice handling, bruising, and temperature variation.

Whether you're fishing for cod, halibut, salmon, or other species, OptimICE® keeps the catch at its best, from sea to shore.

Why It Outperforms Flake Ice and RSW

The comparison below is based on a typical onboard processing environment for whitefish or groundfish (e.g., cod, pollock). In this scenario:

• Fish are caught at 10°C (50°F)
• Seawater temperature is 12°C (53.6°F)
• Fish are chilled and stored in tubs
• The goal is to reduce core temperature to 0°C (32°F) or below, without freezing the product

Why It Matters

In today's seafood market, quality beats quantity — and that starts at sea.

With OptimICE®, fish are chilled instantly and gently from the moment they're caught. This protects texture, appearance, and freshness, resulting in better handling, minimal bruising, and lower bacterial activity during the entire journey from catch to consumer.

That translates directly into:

• Higher-grade product classifications
• Longer shelf life
• Improved food safety
• And most importantly: a better price per kilo

By investing in rapid, even chilling, onboard, fleets can maximize the value of every fish, not just the volume of their catch.

In a market that increasingly rewards premium quality, OptimICE® gives you the edge where it matters most.

By KAPP | Smarter Chilling. Better Seafood.

You don’t need a PhD to know that fresh fish sells better. But a recent Icelandic study reveals just how much temperature control onboard can make or break the value of your catch. In Alaska, you can do everything else right, the gear, the timing, the crew, and still leave money on the table if your chilling system doesn’t get the job done fast.

That’s the reality that Icelandic researchers at Matís explored when they ran a head-to-head comparison between two fishing trips for Pacific cod. One used an old-school RSW tank. The other used a modern slurry ice system. Both were processed the same way, landed at the same plant, and tracked through shelf life and auction.

What They Found:

Key insight: The fish were identical at the point of harvest. But by the time they hit the market, one batch fetched a higher price simply because it was chilled faster and more evenly.

Why This Matters to Alaska

Many Alaskan vessels, especially in the groundfish and halibut sectors, are still using aging RSW systems that can’t cool quickly or uniformly. And with today’s markets demanding traceability, consistency, and longer shelf life, that’s a growing liability.

Alaska competes in global markets that reward quality, shelf life, and handling. Whether you sell directly, through processors, or at auction, buyers know the difference, and they’re paying for it.

The Fix: Upgrade Your Chill

It’s time to stop thinking of chilling as a support system and start treating it as a profit system. Whether you're looking to boost your brand's value, reduce rejected shipments, or hit premium markets, chilling is the first step.

At KAPP, we deliver modern slurry ice systems like OptimICE®, engineered to give you:

• Faster cooling
• Uniform temperatures
• Extended freshness
• Better returns

Better chilling starts onboard. Better prices start with you. Let’s talk about bringing smarter chilling to your boat.

Denholm Seafoods’ new ValuePump system transfers pelagic catch a record distance from vessels to plant in Peterhead, Scotland.

Denholm Seafoods Installs KAPP Skaginn ValuePump System in Peterhead, Scotland

This pelagic season in Scotland saw the first ever direct pumping transport of pelagic catch from ship to plant over a distance of 250 meters. Using KAPP Skaginn’s innovative ValuePump, Denholm Seafoods can now convey product gently through a closed, low-pressure pipe system with ice sludge directly from the ship into the production hall. Starting up in October 2021, the system is powered by KAPP Skaginn’s Value Pump and the accompanying pipe system that is connected directly to the delivering pelagic trawler.
‍

A pump for positive effect

“We wanted to automate more of our processes and find a solution that would positively affect our production flow, quality and costs,” says Richard Duthie, Commercial Director of Denholm Seafoods. “Our efforts to streamline our operation and implement further sustainability measures by not using trucks for catch transport led us to working with KAPP Skaginn on this project.”
‍

Maximizing yield, quality and throughput

Denholm Seafoods operates three modern purpose-built quayside plants in Peterhead, Scotland, which process herring, mackerel, horse mackerel and blue whiting. Different trawlers supply Denholm Seafoods with the raw material, each with their own type of delivery system that can be connected to the ValuePump transfer line at the dock. The new method not only keeps costs down, eliminating truck traffic between trawler and factory, but also maintains a regulated, steady flow of raw material into production that maximizes yield, quality and throughput.
‍

A groundbreaking solution for catch transport

“No one has used this method before over this distance. We decided to go for it and chose KAPP Skaginn as our partner,” says Wayne Summers, Engineering Manager at Denholm Seafoods. “We’ve had a long-standing relationship with them and we knew what they could do. With them and our inhouse experts we developed a groundbreaking solution for catch transport that helps us enhance our operation and keep our quality levels where we want them.”  
‍

Pumps 60 tons of fish over 250 meters

Located in a new reception house on the quay, the system is made up of stainless-steel pipelines, a reception tank with conveyors and the automatic ValuePump that transfers 60 tons of pelagic fish per hour over a distance of 250 meters. “The screw pump method treats the raw material well, maintaining the quality of the catch through the process,” says Duncan Yule, Engineering Manager at Denholm who participated in the development of the project. “Our flow control is now a stepless process making it easy to adjust the capacity and throughput to what we need for production.”

‍

‍Energy saving method supports sustainability

The ValuePump process creates substantial energy savings both in terms of the operational costs of the system itself — the ValuePump’s energy consumption is far less than that of conventional pumps — and in terms of eliminating traffic on the docks and the accompanying fuel consumption. “We have strict quality control standards that are designed to deliver quicker turnaround for our customers and keep our products sustainable,” says Duthie. “This latest addition to Denholm Seafoods operation is yet another step in lowering our carbon footprint.”

Better flow control, better temperature control

The new system delivers product optimized for further processing in a steady, regular flow, from vessel to factory. “There is a steady flow of fish in fluid ice from the pump into the plant without any pulse or variations,” explains Johannes Weber, Mechanical Design Engineer at KAPP Skaginn, who oversaw the installation at Denholm. “With a continuous pace and a well-regulated, steady temperature, Denholm now has a consistent automatic supply of quality raw material coming in for further processing.”  
‍

Gentle product handling maintains quality

During the Mackerel season, Denholm Seafood has seen the Value Pump deliver high quantities of raw material at a steady pace over longer distances than possible before. The gentle propelling principle of the ValuePump treats the raw material gently and along with the cooling capacity of the fluid ice, maintains the quality and value of the fish in the pipeline. “The ability to further cool the product in the system has proven to be very beneficial,” explains commercial director Duthie. “As a matter of fact, our Japanese buyers have commented on the better quality of our product after we installed the ValuePump.” Better quality is also gained by preventing product from being exposed to external stressors in the transfer process.
‍

Collaborative effort key to success

"We started this development project after seeing trials in Iceland. When we saw the potential of the prototype there was no turning back. We had to have it,” says Duthie. “Our collaboration with KAPP Skaginn has gone really well and their hands-on approach has delivered the result we wanted. It has all worked out well, the system exceeded our expectations and the project has been successful."

Mowy’s factory manager dubs the RoteX Sub-chilling system the Rolex of cooling in an interview with iLaks.no

Mowi Improves Salmon Quality and Sustainability with RoteX Sub-Chilling™ System

‍Mowi, the world’s largest producer of Atlantic salmon, decided to invest in the innovative and iceless SUB-CHILLING™ system from KAPP Skaginn in May 2020. Less than a year later the system was up and running in Mowi’s facility in Herøy, Norway. The facility is the largest salmon slaughterhouse to date that uses the patented cooling technology to deliver quality, freshness, and sustainability to its customers around the globe.

Making headlines

iLaks.no, Norway’s most read aquaculture-news site recently did a feature on Mowi’s new SUB-CHILLING™ system, where factory manager Gunnar Hamarsland declared his satisfaction with the system, describing the results as fantastic: “To put it metaphorically, the tank is a RoteX, but I have named it the Rolex,” he said to journalist Steve Hernes.

Iceless sub-zero chilling with a 100 cubic meter RoteX tank

The heart of the SUB-CHILLING™ system at Mowi’s facility is a 100 cubic meter RoteX tank designed to keep fish chilled, ice-free and fresh for longer without freezing the product. Utilizing saltwater that doesn’t freeze at 0° the system turns the fish itself into the cooling refrigerant. The fish stays cool for longer without the need for ice, maintaining better product quality and extending shelf life by up to 7 days.

Shipping more products in each trailer

The lack of ice not only contributes to improved product quality but also plays an important role in improving the sustainability of large and small operations and delivering significant savings in shipping. iLaks.no reports that the weight of ice in a single semi-trailer can be up to 4 to 5 tons. By removing the need for ice more products can be shipped for the same price.

Scaling success to reach 100% of production

So far, Mowi has delivered over 100 tons of fish using far less ice than before to customers in Europe and Asia as part of the system’s testing phase: “Our goal is to do this on a much larger scale. So far, we have run this as separate orders, where we do our tests and measurements here, while the customer reports the status of the fish on arrival,” said production manager Tom Leirvik to iLaks.no, noting that so far the feedback they have received has been very positive. “The experiments we have done since March have confirmed the theory itself, that it is fully possible [to ship fresh fish without ice]. We intend to run this on 100% of our production,” added Hamarsland.

Up and running after 3 weeks

The installation took around three weeks to complete and included extensive upgrades and improvements to existing systems at the facility. A system for mixing salt and water was installed with 700 meters of stainless-steel pipes and 125 remote-controlled valves. “We worked hard for three weeks to get the system up and running. This was an important milestone for us since Mowi is a large and forward-looking company seeking to reduce their carbon footprint and optimize their operations along the way, using our SUB-CHILLING™ technology,” explains Magni Veturliðason, General Manager of KAPP Skaginn AS, Norway.

Better quality with faster ROI

KAPP Skaginn’s SUB-CHILLING™ system is suitable for a range of applications both onboard and on-land and can be configured for a wide variety of species. Tried and tested by whitefish and salmon producers in Iceland and Norway, the system has proven to deliver quality, freshness, and a high return on investment. As the seafood industry in general and salmon in particular, continue to grow in the coming decades, SUB-CHILLING™ is set to play an important role in reducing transport costs, improving shelf life and preserving quality and leading the way to a more sustainable industry.

KAPP Skaginn installs a brand-new production deck built around the RoteXTM chilling and bleeding system that delivers superior raw material quality.

Eskøy Installs New Onboard Whitefish Factory with KAPP Skaginn’s RoteX™ System

A fully equipped new processing deck aboard former longliner, now Danish seine trawler, Valdimar H marks the latest success in the well-established relationship between Norway’s Eskøy AS and KAPP Skaginn. As part of a complete rebuild of the ship, the turnkey onboard factory features a RoteX bleeding and chilling system for immediate processing, along with a full gutting, by-catch and heading line from KAPP Skaginn. As a longstanding supplier to Ice Fresh Seafood, Eskøy is committed to full traceability, sustainability and maximum raw material utilization. With this installation completed in December 2021, Valdimar H is about to set sail and deliver the high-quality product Eskøy set out to achieve.

Building on 13 years of success

“We chose KAPP Skaginn because of their tried and tested systems, which we have used onboard our ships since 2009,” says Hrafn Sigvaldason, CEO at Eskøy AS. “Any project involving KAPP Skaginn has stood the test of time and the service has been outstanding.” For over a decade, Eskøy and KAPP Skaginn have thus continued to foster their relationship, which is rooted in a shared vision: Providing customers and consumers with high-quality sustainable products while ensuring maximum efficiency and superior product handling.

Full control over bleeding and chilling

The heart of the production deck is the highly popular RoteX Onboard bleeding and chilling solution. The high-capacity system provides complete control of the process with integrated software for time and temperature management. This guarantees that every single fish receives exactly the same level of treatment so that excellent fillet quality can be achieved.

Better handling, faster processing

“What we are looking to achieve with this investment is fast and effective bleeding and chilling of the catch, along with an excellent production flow without having to drop or lift the fish,” says Hrafn Sigvaldason. “This solution thus provides much better handling while allowing us to process the fish faster, something that will pay dividends down the line.”

High throughput and efficient by-catch handling

Once the catch has been bled and chilled in the RoteX, it enters the production line where the primary catch of cod and haddock is sent on to gutting and heading before entering the hold. By-catch is kept chilled in tubs and processed later, allowing for flexibility and prioritization in production.

Better quality, longer shelf life with Sub-Chilling

Research has shown that rapid chilling during the initial stages of processing results in an extended rigor mortis period that increases the overall quality and shelf life of the product. Longer and consistent shelf life creates favorable opportunities in logistics as well as considerable savings, something KAPP Skaginn has sought to capitalize on in its design. Eskøy’s new production deck was planned with expansion in mind. Down the line, the RoteX system can be fitted with KAPP Skaginn’s Sub-Chilling technology, which can further improve the quality and handling of the catch. For Eskøy this is a key factor in expanding their business in the future.

Precision automation and quality control

Ragnar A. Guðmundsson, Director of Sales Operations in Scandinavia and Europe at KAPP Skaginn considers this project as yet another success. “Working with Eskøy for the last decade has been a pleasure. Hrafn and I share the background of growing up in a small fishing village and being around fishing and fish processing our whole lives. We have been able to build upon this to communicate clearly and collaborate on numerous projects with remarkable results. They have sought us out for the precision automation and quality control that we pack into a small footprint for our onboard equipment and the service we have delivered,” explains Ragnar.

Sub-Chilling for Noruega in the North Sea

“As more producers set their sights on shorter production time and superior catch handling, we have seen our onboard operations grow significantly with several successful projects installed, planned and underway,” says Ragnar. “Another exciting project in Scandinavia at the moment is Noruega’s trawler Havfjord, which is being built at the Karstensens Shipyard in Skagen, Denmark. We are supplying them with a Sub-Chilling system that will keep the North Sea catch as fresh as can be and guarantee the absolute best results.”

Icelandic family run fish processor Fiskkaup has signed a contract with KAPP Skaginn to install an onboard processing deck for their new vessel Kristrún RE-177. The new facility is designed to process high-quality frozen Greenland halibut. The two companies have had a long-standing relationship. KAPP Skaginn supplied Fiskkaup’s previous onboard system as well as equipment for their modern processing facility in Reykjavík.

Fiskkaup Installs New Onboard Processing System for Kristrún RE-177 with KAPP Skaginn

Sustainable system for onboard halibut processing

‍The new production system from KAPP Skaginn is designed with efficiency, quality raw material handling and sustainability in mind. Committed to responsible fishing in harmony with the environment, Fiskkaup has a Marine Stewardship Council (MSC) certification as a sustainable fishery and is a part of the Iceland Responsible Fisheries consortium. KAPP Skaginn developed an innovative and flexible processing deck in line with the company’s sustainability principles, emphasizing maximum raw material utilization, freshness and quality.

‍

Back for more based on durability and reliability‍

“Our facilities are all first-class, and the newest technology is used to ensure constant quality all year round,” explains Ásbjörn Jónsson, CEO of Fiskkaup. “KAPP Skaginn outfitted our previous vessel with an onboard system in 2012 that has operated seamlessly ever since. The reliability and efficiency of our existing solutions from Skaginn 3X was one of the reasons we decided to contact them again to install a new processing system for Kristrún RE-177.”

‍

Maximum quality and raw material utilization is key ‍

Fiskkaup is one of a few companies in Iceland that specializes in the fishing and processing of Greenland halibut. Their operation hinges on quality and they have mastered it well. By processing and freezing the fish at sea – when it is of the highest quality – the company is able to provide a steady supply of quality product to the Asian market. Heads and tails are also processed and frozen onboard as they also go for a robust price in the same market. KAPP Skaginn’s new onboard facility is thus designed to maximize both quality and the total available catch value.

“Product quality and maximum raw material utilization are very important to us,” says Ásbjörn Jónsson, CEO of Fiskkaup. “We are supplying high-quality Greenland Halibut to the Asian market and every part of the fish counts, as demand from the market has been strong. The new system is designed to utilize the entire fish and deliver quality product.”

‍

Close cooperation with management and crew ‍

As a family business, with decades of experience in supplying high-quality fish products to their customers, Fiskkaup works closely with both their suppliers and their staff. The crew onboard Kristrún – led by captains Helgi Aage Torfason and Pétur Karls­son – worked closely with KAPP Skaginn to create the most ergonomic layout and the most efficient production flow possible. These experienced fishermen hold the 2021 record for the largest Greenland halibut catch, netting over 2000 tons on the previous ship.

‍

Ergonomic system with a small footprint ‍

“This project was a pleasure to work on as both the management of Fiskkaup and the ship’s captains and crew were involved from the start,” says Böðvar Már Styrmisson, sales engineer for the project at KAPP Skaginn. “This ensured that we designed an ergonomic, efficient system based on interdisciplinary cooperation where engineering, processing, manufacturing and firsthand production experience came together to create the best system for this vessel. The guys onboard know what works and what they need and we are dedicated to deliver durable, robust systems that withstand the harsh conditions of processing at sea.”

Set to increase throughput and yield with the same manpower
The system is ergonomic and compact, utilizing space and available manpower to the max. “We are set to deliver increased throughput and better yield with the same manpower as Fiskkaup’s previous ship had,” explains Ingvar Vilhjálmsson, KAPP Skaginn’s Regional Sales Manager for Europe. “Our flexibility enables us to meet diverse needs from our clients. In this case we are integrating existing pieces of heading and freezing equipment into our overall design with KAPP Skaginn’s buffering, grading, bleeding, cutting and packing applications.”

Brødrene Karlsen Installs Norway’s First RoteX Sub-Chilling™ Tank from KAPP Skaginn

Brødrene Karlsen AS is a production company for farmed and wild fish products located at the island of Husøy in Senja, northern Norway. The location, which is at the gateway to the Barents Sea, provides them with a very good source for extremely fresh and high-quality products. In collaboration with a modern and active fleet, they have gained a position in the market, which is associated with highly good product quality. 

Br. Karlsen AS is now taking another step in raising product quality in the market by investing in a new buying station for wild-caught whitefish. This buying station, supplied by Melbu Systems AS, focuses on gentle and efficient processing of the fish with a particular focus on optimizing its quality. In collaboration with Melbu Systems AS, KAPP Skaginn will deliver a RoteX Sub-Chilling™ tank to Br.Karlsen AS. They will therefore be the first whitefish facility in Norway to install this unique cooling solution. 

The concept of SUB-CHILLING™ is to chill the fish down below zero degrees Celsius, where the core temperature of the fish gets close to -1°C. Although the temperature of the fish is below the freezing point of water, the fish remains fresh and unfrozen in a subzero state. A Sub-Chilled fish is refrigerated in such a manner that it is not necessary to add ice to the fish boxes, which means that transport weight is reduced and the problem of water run-off from trailers is eliminated.

KAPP Skaginn Sub-Chilling™ also ensures the lowest possible bacterial growth in the fish, which in turn means longer shelf life out in the market. The fish become firm and fine and are very suitable for further filleting with a clearly reduced risk of fillet gaping. All in all, this means that KAPP Skaginn Sub-Chilling™ is a very good cooling solution for the environment, product quality and production economy in the industry.

KAPP Skaginn has signed a contract with BlueWild, Norway, to supply a full fish processing factory onboard the company’s innovative new trawler. The trawler is designed to deliver sustainability, quality, and efficiency on all levels. From new propeller technology and groundbreaking trawl handling, to ecofriendly catch pumping and innovative production facilities, the new trawler is set to revolutionize onboard processing with its ECOFIVE concept.

A milestone agreement for onboard factory

“The agreement marks a turning point for us,” says Ragnar A.Guðmundsson, KAPP Skaginn’s Director of Sales for Scandinavia and Europe. Mr.Guðmundsson has led the project from KAPP Skaginn end from the beginning. "We have worked closely with the Bluewild team for the last two years. After many meetings and researches the team effort paid off and we will deliver a new and exciting onboard processing solution that harmonizes really well with their strategy."

Fish processing innovation

The concept of responsible fisheries is at the core of the new project. ECOFIVE – the new and innovative concept developed by Bluewild and their partners – is designed to deliver the highest-quality products possible with reduced energy consumption. The concept is nominated for The Nor-Fishing Foundation Innovation Award 2022.

“It’s an incredible opportunity to be chosen as the fish factory supplier for such an innovative project,” says Mr. Guðmundsson. “Our onboard processing system fits incredibly well with the principle of sustainable fishing, maximum product utilization and increased product and by-product value.”

Sustainable fish processing principles in play

Catch is transferred directly into water-filled storage tanks below the waterline where it remains alive before being taken to the factory facility. Overpressure release is used to bring the live catch to KAPP Skaginn's processing line on the factory floor. The turnkey processing system will process fillets, loins, center pieces, tails, and bellies from whitefish, cooked and single-frozen consumer prawns or deliver blocks of industrial shrimp for further production on land.

Top quality, from filleting to frozen product‍

"Our focus is on quality and maximum product utilization,” explains Guðmundsson. “This means that each and every piece offish receives top treatment throughout the process, from filleting to frozen product. In addition, the system’s full product utilization methods are designed to deliver maximum by-product value, that means every part of the fish is processed for human consumption."

Collaboration is the key to success‍

The ship and all of its systems are designed and built by incredibly professional teams from the Westcon shipbuilder, Ulstein Design & Solutions AS, CFlow Systems, PTG and now KAPP Skaginn.  "We are honored that the customer has chosen our company for this project and very proud to be a part of this group", says Mr. Guðmundsson. “Our experience in the Icelandic and international fish industry has allowed us to build world-class teams. Our people bring in-depth processing knowledge, extensive technical expertise, and innovative thinking to this venture.”
