A merchant ship, merchant vessel, trading vessel, or merchantman is a watercraft that transports cargo or carries passengers for hire. This is in contrast to pleasure craft, which are used for personal recreation, and naval ships, which are used for military purposes.
Lake freighters, or lakers, are bulk carrier vessels that operate on the Great Lakes of North America. These vessels are traditionally called boats, although classified as ships.
The T2 tanker, or T2, was a class of oil tanker constructed and produced in large quantities in the United States during World War II. Only the T3 tankers were larger "navy oilers" of the period. Some 533 T2s were built between 1940 and the end of 1945. They were used to transport fuel oil, diesel fuel, gasoline and sometimes black oil-crude oil. Post war many T2s remained in use; like other hastily built World War II ships pressed into peacetime service, there were safety concerns. As was found during the war, the United States Coast Guard Marine Board of Investigation in 1952 stated that in cold weather the ships were prone to metal fatigue cracking, so were "belted" with steel straps. This occurred after two T2s, Pendleton and Fort Mercer, split in two off Cape Cod within hours of each other. Pendleton's sinking is memorialized in The Finest Hours. Engineering inquiries into the problem suggested the cause was poor welding techniques. It was found the steel was not well suited for the new wartime welding construction. The high sulfur content made the steel brittle and prone to metal fatigue at lower temperatures.
Handysize is a naval architecture term for smaller bulk carriers or oil tanker with deadweight of up to 50,000 tonnes, although there is no official definition in terms of exact tonnages. Handysize is also sometimes used to refer to the span of up to 60,000 tons, with the vessels above 35,000 tonnes referred to as Handymax or Supramax.
The Type C4-class ship were the largest cargo ships built by the United States Maritime Commission (MARCOM) during World War II. The design was originally developed for the American-Hawaiian Lines in 1941, but in late 1941 the plans were taken over by the MARCOM.
The Furness Shipbuilding Company was a shipbuilding company in Haverton Hill, Stockton on Tees, England. It was established during the First World War and operated from 1917 until 1979.
Algoma Mariner is a Canadian lake freighter delivered to Algoma Central on 31 May 2011. The bulk carrier was the first new Canadian-flagged vessel on the Great Lakes in 25 years. Algoma Mariner is a Seawaymax vessel, designed to carry dry bulk through the Saint Lawrence Seaway and Great Lakes. The vessel was constructed at the Chengxi Shipyard in China and is currently in service.
MV Algonorth was a Seawaymax lake freighter built in 1970 and completed in 1971 by the Govan Division of Upper Clyde Shipbuilders Ltd. in Govan, Scotland as the bulk carrier Temple Bar. Her original owners were Lambert Bros. Shipping Ltd., of London, United Kingdom, sold the vessel in 1976 to Nipigon Transport Ltd., who had her hull lengthened and installed a new power plant for Great Lakes service. Re-entering service as Lake Nipigon, the ship was renamed Laketon in 1984 before returning to the name Lake Nipigon in 1986. In 1987, the lake freighter was sold to Algoma Central Railway which gave the ship its final named, Algonorth. In 2007, the ship collided with a dock in Toledo, Ohio. The ship was scrapped in 2012.
Sauniere was a self-unloading bulk carrier operated by Algoma Central. Laid down as Bulknes, before launching the vessel's name was changed to Brooknes. The ship was constructed and completed in 1970. The ship was initially owned by the Swedish company Kristian Jebsens Rederi A/S. In 1974, Algoma Central purchased the vessel, registered the ship in West Germany and renamed it Algosea. Algoma Central sent the ship to Swan Hunter in England to be lengthened. Emerging in 1976, Algosea sailed for Canada for conversion to a self-unloading bulk carrier at Herb Fraser and Associates in Port Colborne, Ontario. Algosea, which transported road salt between ports in the Gulf of St. Lawrence, Saint Lawrence Seaway and Great Lakes suffered three collisions and two groundings during its career. The Algosea was renamed Sauniere in 1982 and continued in service until 2009 when the bulk carrier was sold for scrap and broken up in Turkey in 2010.
Algoma Equinox is a lake freighter and lead ship of her class built for Algoma Central, a Canadian shipping company. The vessel was built to a new design by Nantong Mingde Heavy Industries at their shipyard in Tongzhou, China in 2013. The ship entered service in December 2013, operating in the Great Lakes and Saint Lawrence Seaway.
English River was a lake freighter and bulk carrier, launched in 1961 by Collingwood Shipyards of Collingwood, Ontario. In her initial years she carried bulk cargoes and deck cargoes to smaller ports on the Great Lakes and Saint Lawrence River watershed and estuary. In 1973, the vessel was converted into a cement carrier and carried mainly raw cement for the construction industry. The ship continued to operate until English River was removed from service and sold for scrap.
Algoma Navigator was a Canadian bulk carrier operated by Algoma Central. Like other bulk carriers, her potential cargoes included: coal/coke, aggregates, slag, iron ore/oxides, salt, fertilizers, grain products, gypsum, quartzite, or sand. The vessel was constructed by John Readhead & Sons in the United Kingdom in 1967 for the Cambay Steamship Company and launched as Demeterton. The vessel was enlarged in 1967 and sold in 1975 to the Upper Lakes Group which renamed the ship St. Lawrence Navigator. In 1979, the vessel was renamed Canadian Navigator after a rebuild. In 2011, the ship was sold to Algoma and became Algoma Navigator. In 2016, the bulk carrier was renamed Navi before being sold for scrap and broken up in 2016.
CSL Tadoussac is a lake freighter currently operated by Canada Steamship Lines (CSL) on the Great Lakes. She was launched in 1969. Initially named Tadoussac, following her refit in 2001, she was renamed CSL Tadoussac She was the last freighter built for CSL in the traditional two superstructure design, which puts her bridge up in the ship's bow. The vessel primarily transports iron ore and coal.
Algogulf was the third and last name of a bulk carrier launched in 1961, laid-up in 1999, and scrapped in 2002. The ship began her career in 1961 as J.N. McWatters, the second vessel of that name operated by the Misener Shipping Company. The bulk carrier was used to transport primarily grain and iron ore in the Saint Lawrence Seaway and Great Lakes. In 1991, the vessel was renamed Scott Misener by the company, the fourth of that name. In 1994, the ship was acquired by Algoma Central and renamed Algogulf, the second vessel of the name. The ship was laid up in 1999 and sold for scrapping in 2002.
The Trillium class is a series of freighters owned by Canada Steamship Lines (CSL). The class is divided into three subclasses; the self-discharging lake freighters, the lake bulk carriers, and the Panamax self-discharging bulk carriers. Initially a nine-ship building program, six are operated by Canada Steamship Lines for use on the Great Lakes, while three are operated by CSL Americas for international trade. Two more ships were acquired later for use by CSL Americas.
The T1 tanker or T1 are a class of sea worthy small tanker ships used to transport fuel oil before and during World War II, Korean War and Vietnam War. The T1 tanker classification is still in use today. T1 tankers are about 200 to 250 feet in length and are able to sustain a top speed of about 12 knots. The hull designation AO is used by the US Navy to denote the ship is a T1 oil tanker and AOG that the T1 is a gasoline tanker. The small size allows the T1 to enter just about any sea port or to anchor around a small island, this was very useful during the Pacific War. The T1 tanker can carry about 48,000 to 280,000 bbls. Some T1 tankers were used to transport goods other than oil, a few were used for black oil-crude oil, diesel, chemicals and rarely bulk cargo like grain. T1 tankers are also called liquid cargo carriers. The T1 tanker has about a 6,000 to 35,000 deadweight tonnage (DWT) of cargo. The small size also gives the ships short turn around time for repair, cleaning, loading and unloading. A T1 tanker carrying dirty cargo, like crude oil needs a few weeks of labor to clean before carrying clean cargo. Most T1 ships during World War II were named after major oil fields.
The Type L6 ship is a United States Maritime Administration (MARAD) designation for World War II as a Great Lakes dry break bulk cargo ship. The L-Type Great Lakes Dry Bulk Cargo Ships were built in 1943 to carry much-needed iron ore from the upper Great Lakes to the steel and iron production facilities on Lakes Erie and Ontario in support of the war effort. The ships have a 15,675 tonne deadweight tonnage. The L6 ships were built by two companies: American Ship Building Company, in the case of the type L6-S-A1 models, of which 6 were built; and Great Lakes Engineering Works, Ashtabula, Ohio/ Great Lakes Engineering Works, River Rouge, Ohio, in the case of the type L6-S-B1, which produced 10 ships. Steel supply needed for World War was great. To supply iron ore from Lake Superior to steel foundries, the United States Commission had a series of L6 Lakers ship built. The Maritime Commission ordered ten Great Lakes Bulk Carriers of the L6-S-B1 type. The L6-S-B1 was design with a 3-cylinder triple expansion steam engines. The L6-S-A1 used a lentz 4-cylinder compound engine. All L6 ships were coal burning and delivered between May and November 1943. L6-S-B1 was built for the US Maritime Commission under USMC contract MCc-1834 in 1943 at the River Rouge yard. Each L6 ship cost $2.265 million. The first L6-S-B1 was the SS Adirondack/Richard J. Reiss, hull 290, keel was laid on March 9, 1942 and launched on September 19, 1942. The ships are often called the Class Lake Bulk Freighter now.
Algoma Provider was a Canadian lake freighter, which operated from 1963 to 2013 under the flag of several shipping lines. She was built to seawaymax dimensions at the Collingwood Shipyards in Collingwood, Ontario for Canada Steamship Lines. She was powered by a steam turbine, and was the company's last steam-powered vessel. Initially named Murray Bay, the ship was sold in 1994 to Upper Lakes Shipping, which renamed the vessel Canadian Provider. In 2011, Upper Lakes Shipping sold its entire fleet to Algoma Central, which renamed the lake freighter Algoma Provider. The vessel continued in service until 2013, when she was sold to be broken up for scrap. The ship was renamed Ovi for her journey to the scrapyard in Turkey. During her career, the ship carried bulk cargoes to destinations along the Saint Lawrence Seaway and Great Lakes.
Algoma Sault, which entered service in 2018, is the third freighter Algoma Central named after Sault Ste. Marie, Ontario. She is a self-unloading bulk carrier, built for carrying cargoes like ore, grain, or coal, on the North American Great Lakes and St. Lawrence Seaway. She is the seventh vessel of the Equinox class, and like her sister ships she was built in China.
Welding Shipyards was founded by American shipping businessman, Daniel K. Ludwig (1897–1992) in 1940 at Norfolk, Virginia on the Sewell's Point peninsula. Welding Shipyards build T3 tanker ships for World War II under the Emergency Shipbuilding Program. Welding Shipyards had one construction berth with 600 workers. The shipyard built what Ludwig was known for Oil tankers. Welding Shipyards built five type T3-S-BF1 tankers, the largest at the time. Ludwig' Welding Shipyards used what is called block construction. To shorten keel to ship launching time due losses to German U-boats, block construction was used. Ships blocks were built as the keel was being laid and then the prefabricated parts were then put in place and welded. With this construction time was reduced dramatically. Welding Shipyards and Ludwig had an important role in this new type of construction. All of the tanker ships were operated by Ludwig's shipping company that he founded, the National Bulk Carriers in 1936 in New York. National Bulk Carriers owned and operated oil tanker ships and bulk carriers. Some of the ships were among the largest in the world at that time. In 1953 Ludwig moved the shipyard operated to the Kure shipyard in Japan. Ludwig leased the Japanese navy Kure yard for 10 years. The Welding Shipyards site today is part of the Naval Station Norfolk. In 1940 and early 1941, Welding Shipyards converted older World War I surplus cargo ships into oil tankers.
