The practice of this fishery can mainly be divided into two operations: setting and hauling of line. In this fleet group, the setting operation is mechanized and takes place automatically; The hooks on the line are automatically fitted while the line goes out of the vessel. However, the tail operation is of a more manual nature on most vessels. It is common for the line to be hauled into the vessel over a row roll in a hatch in the ship's side on the factory deck, which is 2–3 meters above the water surface. Next to the reel there is always a crew member who secures and lifts the fish that comes up by using a hook (clap) which is preferably hit in the fish's head. The speed of a hauling line varies, but on the most efficient vessels up to 50 meters / min. The distance on the hooks is around 1.3 meters, so if there is a lot of fish on the line, it is a very demanding and stressful for the crew to lift in all the fish. This often leads to misalignment with the cap, which damages the quality of the fish if you hit the fillet, in addition to the fact that there is some loss of fish when it becomes too hectic.
To avoid these problems, an attempt has been made to automate the process. As of today, there are two systems that are prominent:
• Moonpool technology (dragon well). This is implemented on M / S “Geir”. This means that the line is hauled through a well in the center of the hull (in the middle of the keel). This technology ensures the least possible movement where the line enters, and that lost fish that float are left to float in the well so that the crew can easily catch it.
• Automatic line hauler (ALH). This is mounted on M / S “Loran”) Here an adjustable hatch of 1x1 meters is mounted in the water surface through which the line is hauled. Lina then goes through a shaft with a conveyor belt that collects fish that loosen. Fish that do not come loose in the shaft are worn loose (hooked) from the line in the tail compartment know that the line goes between two rolls that are so tight that only the line comes between.
Goal: to make documentation of the various technical solutions that today's autoline fleet has available in such a way that the effect of the various solutions can be communicated back to the industry. It is further assumed that the data material from the cruise should be of such a quality that they could be used as a basis for one or more publications in an international journal.
Sub-goal
1. To make an objective comparison of the three existing tail systems that currently exist in the autoline fleet. Here, special emphasis was placed on the technologies' ability to catch fish at different tail speeds.
2. To document the various work operations on an autoline vessel with regard to HSE. Here, too, emphasis was placed on how the various tail technologies affected the work, but one also wanted to map the other operations that took place on board, such as factory and split / setting.
To follow the catch taken under different conditions throughout the production process from sea to consumption. This is to gain a better understanding of how the individual links in the production chain affect the quality of the end product.
