We serve the fishing industry in multiple capacities, including offshore fueling from petroleum barges during the fishing season and in-port fueling services for fishing boats in Western Alaska and along some river communities. The town of Grimsby on Lincolnshire's east coast once laid claim to the title of the 'largest fishing port in the world', Its fleet of over 700 trawlers and the rail links from the town to London's Billingsgate Fish Market allowed Grimsby fish to be renowned nationwide.
The largest fishing port in Europe from the 1970s onwards has been Peterhead in the North-East corner of Scotland. Modern trawlers make extensive use of contemporary electronics, including navigation and communication equipment, fish detection devices, and equipment to control and monitor gear. Navigational instruments, such as an autopilot and GPS, are used for manoeuvering the vessel in harbour and at sea.
Radar can be used, for example, when pair trawling to keep the correct distance between the two vessels. During trawling operations, a range of trawl sensors may be used to assist with controlling and monitoring gear.
Commercial fishing is a high risk industry, and countries are introducing regulations governing the construction and operation of fishing vessels. Here is a photograph from NOAA, showing how a Loggerhead sea turtle escapes from trawl net through a Turtle Excluder Device. Here is an interesting video clip to show how a sea turtle escapes from trawl net through a Turtle Excluder Device. And below it, you can see how many pieces of news have been created about commercial trawler in the last years.


In addition, our Jensen Maritime subsidiary is a world-renowned designer of all types of fishing boats–from trawlers, seiners and line vessels to crabbers, tenders and processors. Many different kinds of vessels are used in commercial, artisanal and recreational fishing. At the other extreme, two-thirds (1.8 million) of the undecked boats are traditional craft of various types, powered only by sail and oars. They range in size from small dingies to large charter cruisers, and unlike commercial fishing vessels, are often not dedicated just to fishing. During World War I and World War II, many fishing trawlers were commissioned as naval trawlers to be used as minesweepers, the activities being similar, with the crew and layout already suited to the task. During the Cold War, some countries fitted fishing trawlers with additional electronic gear so they could be used as spy ships to monitor the activities of other countries. Today Grimsby's fish docks are virtually deserted, though the towns port is still a hive of activity for cargo vessels. In its prime in the 1980s Peterhead had over 500 trawlers staying at sea for a week each trip. Trawl winches, such as Gilson winches, net drums and other auxiliary winches are installed on deck to control the towing warps (trawling wires) and store them when not in use. Smaller trawlers have wheelhouses, where electronic equipment for navigation, communications, fish detection and trawl sensors are typically arranged about the skipper's chair. In general, the fish are kept fresh by chilling them with ice or refrigerated sea water, or freezing them in blocks.
In the United States and Canada more use is made of large factory trawlers, while the huge blue water fleets operated by Japan and the Soviet-bloc countries have contracted.
Most commercial fishing boats are small, usually less than 30 metres (98 ft) but up to 100 metres (330 ft) for a large purse seiner or factory ship. Though the sea turtles have survived mass extinctions due to natural disasters, threat to sea turtles from fishing industry is increasing. The basic trawl is a funnel shaped net with wide mouth kept open and is towed on the water surface or in the seabed.

Traditionally boats were built of wood, but wood is not often used now because it has higher maintenance costs and lower durability. Peterhead has seen a significant decline in the number of vessels and the value of fish landed has been reduced due to several decades of overfishing which in turn has reduced fishing quotas. Larger vessels have a bridge, with a command console at the centre and a further co-pilot chair. Also, many trawlers carry out some measure of onboard fish processing, and the larger the vessel, the more likely it is to include fish processing facilities.
In western Europe, fishing vessel design is focused on compact boats with high catching power.
Fishing equipment varies in sophistication depending on the size of the vessel and the technology used. For example, the catch can undergo some preliminary processing by being passed through sorting and washing devices. Efforts to reduce threat to sea turtles started from 1970s by designing and testing Turtle Excluder Device (TED). There are many types of trawls such as: Otter trawls, Beam trawls, Fly net trawls including skimmer, roller frame, pair and clam kicking trawls. Small marine species such as shrimp pass through the bars and are caught in the bag end of the trawl. Design features for modern fishing trawlers vary substantially, as many national maritime jurisdictions do not impose compulsory vessel inspection standards for smaller commercial fishing vessels. It is disturbing to note that all the fishing trawlers are not using either TEDs or properly functioning TEDs to protect sea turtles. When larger marine species, such as marine turtles and sharks are captured in the trawl they strike the grid bars and are ejected through the opening. Suitable modifications to TED openings have been carried out to initial TED designs that did not allow release of larger leatherback and hardshell turtles.Interestingly 97 percent success is seen in trawls using properly functioning TEDs.
