MFV “Endurance”

MFV “Endurance”

Project Details

In 2017, KER Group were awarded the contract to supply a blast freezer as well as other components to the MFV “Endurance” fishing vessel.

Project Overview

  • KER completed a number of works on the 27 metre Cork vessel Endurance (DA31) which is owned by Kedge Fishing Limited. Works included supplying and installing another blast freezer on board the vessel to process the catch as swift as possible, while it’s still in first-class condition.

 

  • On its own, the original blast freezer on board the Endurance was capable of freezing prawns to the desirable temperature, however the defrost time was hindering the process somewhat. The additional room was installed as a way of enabling the crew to fill one blast and defrost the other at the same time in order to keep the process of freezing seamless. The new blast room was fitted with a stainless steel racking system, with slide out frames for ease of loading and unloading.

 

  • Engineers at KER were tasked with creating the adequate space for the freezer, so an area in the existing fish hold was framed off with timber and sheeted with marine ply, then covered in fibreglass to provide a smooth, well insulated surface. Two insulated doors were fitted to the newly formed blast freezer in order to provide ease of access for the crew.

 

  • The blast freezer’s coolers were installed in the middle of the blast freezer room, they are situated in such a way as to blow the cold air in opposite directions, giving a continuous & consistent air flow throughout the blast freezing area. A new refrigeration system was installed in the forepeak.

 

  • KER also completed an electrical synchronizing job on the vessel’s generators after an additional generator was installed to insure adequate power was available to run the new blast freezer. A number of other minor but essential works were also carried out on the Endurance before it went back to sea.

 

  • On its first trip back fishing, the crew of the Endurance froze 1.8 tons of squid, which are much denser than prawns, in just 5 hours in the new blast freezer. This amount of squid would normally take around 8 to 9 hours to freeze in the original blast freezer. The new blast freezer brought the squid down to -29 degrees at its core and completed the cycle with a defrosted time of just half an hour.

MFV “Achieve”

Project details

In 2018, KER Group were awarded the contract to supply, a blast room in the fish hold, a new fish hold chilling, and an ice machine on the MFV “Achieve”.

Works completed

Overview
KER Group, supplied and installed the following on board the MFV “Achieve”;
• Blast room in the fish hold
• New Fish hold chilling
• New 3t/24hrs Geneglace Ice Machine
• Fresh Water Maker 2t a day
• Temperature monitoring system.
Blast Room
The original blast system was working well, but the owner wanted to make more use of the space by dividing the room and adding additional chilling. This was achieved by fitting a complete standalone blast unit, and fitting a bulkhead wall creating two rooms.

The new Blast can freeze over 1 tonne of product in 3 hours which means the new system is much more efficient at guaranteeing the quality of the frozen product

Fish Hold Chilling

The existing fish hold system, was fitted with stainless steel piping, the owner wanted to improve the chilling, so a complete new fish hold evaporator was fitted in place, increasing the evaporator to double the size.

Fresh Water Maker

A fresh water maker was supplied and installed. This system runs from the main engine heat and produces fresh water, which is of great benefit. The ice machine can utilise this fresh water for the full trip, without changing over to salt water.

The full refrigeration system is controlled by Eliwell controllers, however, a separate temperature monitoring system was installed to record the data for the trip. This can be presented to the buyer of the fish or the authorities as proof of quality over the duration of the trip.

Ice Machine

A new Geneglace 3t/24hrs ice machine was supplied and installed also.

Testimonial

Since the project was completed, I have fished the vessel on a number of occasions myself, and I am delighted to say that all systems are working very well. The Blast room has exceeded my expectations, it is very quick at taking the temperature down and freezing our catch. This ensures the quality of our product for the fish market.

I highly recommend KER Group for any projects you may be considering.
