MS Midsund som er det nyeste tilskuddet i flåten til Nybonia rederiet har nå fangstet og sendt sine første partier med ferske makrellstørjer i nanois til det Japanske markedet. Prosjektleder og skipper ombord Markus Nygård sier de nå er godt i gang med fangsting av nytt parti som skal sendes.
Spenningen var stor i begynnelsen på hvordan det Japanske markedet responderte på produktene og hvilke priser de kunne forvente å få. Overraskende nok ble det allerede ved første sending gitt veldig gode tilbakemeldinger og MS Midsund traff godt på kvalitets-parameterne Japanerne verdsetter så høyt. Det benyttes line som fangstmetode og fisken tas ombord på en skånsom og effektiv måte.

Nøkkelen til suksess- effektiv og rask nedkjøling

I tillegg til nøye håndtering av fisken gjennom gode fangstmetoder, så er rask nedkjøling, god utblødning og kontinuerlig kjøling et viktig premiss for at kvaliteten skal kunne kategoriseres som et prima produkt i første klasse.

Rask nedkjøling til omlag 0 C° er helt avgjørende for å bremse de metabolske prosessene som fører til nedbrytning av fiskekjøttet. Med rask nedkjøling og kontinuerlig vedlikeholdskjøling så vil Rigor Mortis (dødsstivheten) kunne utsettes og gi et større tidsvindu på pre-rigor prosessering av produktet. Riktig håndtering av kjøling og timing gir derfor et sluttprodukt med optimal smak, tekstur og holdbarhet.

To maskiner av NM 3202, med tilsammen fire isgeneratorer, sikrer at det blir tilført is og superkjølt vann til en hver tid. Is produseres og lagres i distribusjonstank på forhånd, klar til å distribuere større mengder is på kort tid. Under utblødningsfase så kan samtidig en av maskinene produsere og tilføre ferskt superkjølt sjøvann til utblødningsfasen. Dette sikrer fleksibel og god kapasitet.
Tore Sjøvik, daglig leder i nanoICE AS synes det er veldig fint at selskapet får mulighet til å gå inn å være med som partner på både levereing av utstyr samt utvikle metoder for hvordan fordelene med denne type is og anvendelsen kommer brukerne og markedet til gode.

MS Midsund, the newest boat to the fleet of the Nybonia shipping company, has now caught and shipped its first batches of fresh Atlantic bluefin tuna in nano ice to the Japanese market. Project manager and skipper on board Markus Nygård says they are now well underway with catching the new batch to be shipped.

There was great excitement at the beginning about how the Japanese market would respond to the products and what prices they could achieve. Surprisingly, very good feedback was given already on the first shipment and MS Midsund hit the quality parameters that the Japanese value so highly. Line is used as the catching method and the fish is taken on board in a gentle and efficient way.

The key to success – efficient and rapid cooling

In addition to careful handling of the fish through good catching methods, rapid cooling, good bleeding and continuous cooling are important prerequisites for the quality to be categorized as a first-class premium product.

Rapid cooling to around 0 C° is absolutely necessary to slow down the metabolic processes that lead to the decomposition of the fish meat. With rapid cooling and continuous maintenance cooling, Rigor Mortis (the rigidity of death) can be postponed and provide a larger time window for pre-rigor processing of the product. Correct handling of cooling and timing therefore provides a final product with optimal taste, texture and shelf life.

Two NM 3202 machines, with a total of four ice generators, ensure that ice and supercooled water are supplied at all times. Produced and stored in a distribution tank in advance to distribute larger quantities of ice in a short time. During the blanching phase, fresh supercooled seawater can be produced and supplied to the blanching phase at the same time. This ensures flexible and good capacity.

Tore Sjøvik, CEO of nanoICE AS, thinks it is great that the company has the opportunity to be a partner in both supplying equipment and developing methods for how the advantages of this type of cooling are marketed and used to benefit users.

Salthammer Båtbyggeri AS (SHB) overleverte 14. juni 2024 ‘‘C Provider’’ til Charvest AS. Fartøyet ‘’C Provider’’ er det andre bygget levert til Charvest AS fra SHB.

Kontrakten ble signert i april 2023 og fartøyet som er bygget i sin helhet på verftet på Vestnes er en kombinert service og bløggebåt – M19 designet av Møre Maritime AS. Med en største lengde på 19 m og en bredde på 9,4 m. Båten er skreddersydd for bløgging av fisk, men den kan også benyttes som servicebåt utstyrt med stor kran, muligheter for slep og god dekksplass.

Fartøyet er utstyrt med bransjens største batteripakke på denne type fartøy, som gjør det mulig å operere utslippsfritt på merdkanten i opptil et døgn. Batteripakken sammen med den hybride fremdrifts linjen gjør båten fleksibel og i stand til å optimalisere energiforbruket til enhver aktivitet.

Charvest AS har sammen med møre Maritime AS og SHB videreutviklet ‘’Csaver’’ den første båten som SHB leverte til rederi tilbake i 2020, til ‘’C Provider’’ som leveres i dag, basert på erfaringer og nye teknologi. ‘’C Provider’’ er i denne klassen en svært avansert båt med fleksible løsninger for optimalisering av energiforbruk om bord. Leveringen av ‘’C Provider’’ styrker ytterligere Salthammer sin posisjon, som en ledende leverandør av teknologisk avanserte fartøy til oppdrettsnæringen, uttaler Lasse Stokkeland, daglig leder ved verftet.

Levering av utstyr fra NanoICE

NanoICE har levert ismaskin av typen NM 3202 med to flow-ice generatorer for isproduksjon, samt automasjonsløsning for styring av UV rensing og sjøvannspumper fra ismaskin. Med nanoisens egenskaper skal man sikre effektiv kjøling og utblødning i mobile oppsamlingstanker, som er plassert på båtens dekk.

Til tross for sin kompakte størrelse vil ismaskinen produsere nærmere 10.000 liter is om dagen. Maskinen produserer is direkte fra generatorene via slanger, hvor isen fordeles direkte inn i tankene, uten noe behov for manuelt arbeid fra båtens personell.

Nanoisens unike egenskaper bidrar til at fisk blør raskt ut og forhindrer effektivt varmeoppbygging i råvaren under dette viktige og varmefølsomme bearbeidingsstadiet. Dette gir økt kvalitet og gode forhold for god temperaturkontroll.

On 14 June 2024, Salthammer Båtbyggeri AS (SHB) handed over “C Provider” to Charvest AS. The vessel “C Provider” is the second building delivered to Charvest AS from SHB.

The contract was signed in April 2023 and the vessel, which has been built in its entirety at the shipyard at Vestnes municipality, is a combined service and bleed-boat – M19 designed by Møre Maritime AS. With a maximum length of 19 m and a width of 9.4 m. The boat is tailored for bleeding, but it can also be used as a service boat equipped with a large crane, possibilities for towing and plenty of deck space.

The vessel is equipped with the industry’s largest battery for this type of vessel, which makes it possible to operate emission-free on the seashore for up to 24 hours. The battery pack together with the hybrid propulsion line makes the boat flexible and able to optimize energy consumption for any activity.

Charvest AS, together with Møre Maritime AS and SHB, further developed ‘Csaver’, the first boat that SHB delivered to shipping companies back in 2020, into ‘C Provider’, which is delivered today, based on experience and new technology. “C Provider” is in this class and a very advanced boat with flexible solutions for optimizing energy consumption on board. The delivery of ‘C Provider’ further strengthens Salthammer’s position as a leading supplier of technologically advanced vessels to the aquaculture industry, says Lasse Stokkeland, general manager at the yard.

Delivery of equipment from NanoICE

NanoICE has delivered an ice machine of the type NM 3202 with flow-ice generators for ice production, as well as an automation solution for controlling UV cleaning and seawater pumps from the ice machine. With the nano ice’s properties, one ensures efficient cooling and bleeding, in mobile holdingtanks on the boat’s deck.

Despite its compact size, the ice machine will produce close to 10,000 liters of ice per day. The machine produces ice directly from the generators via hoses, where the ice are beeing distrubuted directly into the tanks, without the need for manual work from the boat’s personnel.

The nano ice’s unique properties help the fish to bleed quickly and prevent heat build-up in the raw material during this important and heat-sensitive processing stage. This provides increased quality and good conditions for good temperature control.

M/S Midsund is will be rebuilt to be able to fish for whales and will be able to finish producing much of the catch on board. Catching whales often takes place during periods of warm weather and it is therefore important that you have the opportunity to start effective cooling as soon as you get the catch on board. In addition to whaling, the boat will be rigged for seine seine, where nanoICE can also be used for cooling during harvesting. nanoICE will, for example, be very suitable for cooling  in the first stage during bleeding when the fish is gutted.

A total of one ice machine of the type NM-3202 and two distribution tanks for ice are delivered in this delivery.
Two ice tanks with a capacity of respectively 2200 liters (2000mm X 1200ø) and 3400 liters (3000mm X 1200ø) are supplied to be able to store ice and distribute larger quantities of ice when needed. The tanks comes with agitator and distribution pump.

All equipment are manufactured and delivered in collaboration with our production and salespartner Nomapro AS.

• Reduce greenhouse gas emissions: With supercooling, the ice becomes redundant, and fewer trucks and planes are needed to transport the fish. This reduces greenhouse gas emissions from the fuel.
• Save transport costs: Fewer lorries on the road also naturally mean less transport costs.
• Preserve quality for as long as possible: It usually takes about a day before the temperature of the fish has dropped below 0 degrees. Super-chilled fish reaches this temperature much faster, without being frozen.

Through research, the following quality benefits have been documented:

• Longer shelf life: When fish or animals are slaughtered, they go through a process that eventually ends in putrefaction. Supercooling helps to extend the first phase, where the fish is still of top quality, and thus has a longer shelf life than fish that is placed on ice. The shelf life of salmon chilled with ice is around 20 days, while that of super-chilled salmon can be over 30 days with storage at -2 °C.
• Retain liquid during storage: All fish lose liquid during storage. Fillet that is placed on ice has a so-called drip loss of 0.18 per cent per day. Gutted, super-chilled salmon has almost no drip loss during the first four to five days. A study has also shown that super-chilled, vacuum-packed salmon fillets had less drip loss than traditional chilled fillets.
• Better yield: Firmer fish gives more fillet after filleting, and it has also been shown that the yield of cooked fish is higher when it has been supercooled.

Several advantages are also likely, based on knowledge of the raw material and on the basis of experiences from producers who have super-chilled fish:

• Firmer in the fish: Producers who have delivered super-chilled salmon to their customers report fewer complaints about soft fish and fillet splitting.
• Better taste: Producers have received good feedback on the taste of super-chilled salmon.
