Freezing trawlers are floating fish factories that depend on the speed and efficiency of their astounding collection of machines, and the industrial electrical training of the crew.

Deep within the belly of a freezing trawler is an intricate network of machinery that processes and freezes the trawler’s catch with amazing speed. Fish is an extremely perishable food, and it must be preserved quickly in order to retain its quality and shelf life.

Freezing trawlers are huge, floating fish factories that work the high seas and process and freeze their catch on the spot. Without the ability to freeze fish, trawlers have to return to land as soon as they have a catch, regardless of whether the hold is full or not. Travelling back and forth from port to deep sea with a partially filled hold is highly inefficient. Freezing at sea allows trawlers to remain at sea longer, which is more efficient and ultimately reduces the price of fish to consumers.

Electrical Faults Can Spell Disaster

The freezing trawler is a classic demonstration of a setting where industrial electrical training for the crew is paramount. Isolated out on the deep sea, with the whole operation depending on the smooth running of every machine, the crew has to be able to solve electrical faults in the equipment speedily.

Fishing and Processing on a Freezing Trawler

How the Trawler Production Line Works

The inner workings of one of these vessels are fascinating.

When the trawler makes a catch, a huge net (trawl) bursting with fresh-caught fish is hauled onto the trawler’s deck by a winch.

Workers remove the nets and the fish (dead by this time) slip through a trap door in the down into the receiver, essentially a holding place as the fish are moved along the processing line. They flow at a manageable pace to the first station, where workers feed the fish into a machine that cuts the head off the fish and guts it.

From there, the fish travel by conveyor to a filleting machine, where workers position them and a conveyor belt passes them through razor sharp spinning circular saw blades that produce the fillets.

Next stop is the skinning machine. The fish slide down a metal ramp into waiting mechanical arms that hold the fillets in place and slot them one at a time into the skinner, from which they emerge almost pristine, beginning to resemble what you see in the fish counter at your local grocery store.

But this is only half-way through the process. Skinless fillets are whisked on to yet another station, where human workers trim and clean them further.

Snaking conveyors carry the fish fillets upwards to another machine that weighs them and sorts them according to size, and sends them off to be packaged by humans into boxes that are then forwarded to an on-board freezer.

When the frozen blocks of fish are removed from the freezer, yet another huge machine stacks the boxes and sends them down to the freezing hold, where workers pack them into larger boxes, aided by more machines. The large boxes of frozen fish are stacked neatly in the freezing hold, awaiting the time when the trawler makes another catch and fills it to capacity.

On the same trawler, the scraps and offal left over from processing the fish heading for human consumption is processed into fish meal used mainly to feed farmed fish, so that nothing is wasted.

It’s still hard work for the crew, but the many specialized machines in the production line chain make it possible to process, freeze, and store enormous quantities of fish while they are still fresh from the ocean.

Downtime is a Catastrophe

As you can see, the whole production line is an interdependent chain that whisks fish from deck to before it can perish. Speed is paramount, and these machines certainly deliver.

Imagine, though, what happens when one of the complex machines in this elaborate system goes down. Out in the middle of the ocean, they’re on their own. There’s no one they can call to come and fix the machines. Production grinds to a halt along the whole line, and the entire catch spoils. Any kind of electrical fault in any of these machines can spell economic peril for the trawler and its crew.

That’s why it’s so important that crew members be able to solve production line electrical faults quickly and efficiently, without damaging the equipment or harming themselves or others.

Simutech’s Industrial Electrical Training Software Reduces Downtime

Simutech Multimedia’s Troubleshooting Skills Training System™ is a simulation-based industrial electrical training process that equips staff to solve electrical faults safely and get equipment back up and running as soon as possible.

Simutech industrial electrical training software teaches a systematic, five-step approach to solving electrical problems, which eliminates time wasted in guesswork and means that faults are solved quickly and safely.

For freezing trawlers and for most other manufacturing lines, downtime is disastrous. At Simutech, we know that downtime will happen, but we equip your staff to ensure that it’s as short as possible.
