SD18 (sometimes written SD-18 or SD 18) is the designation of a type of cargo ship, built by Austin & Pickersgill at their yard in Southwick, Sunderland, England in 1980–1981. Only three were built: Murree, Kaghan and Ayubia. The name SD18 stands for "shelter decker, 18,000 tons".
A cargo ship or freighter ship is a merchant ship that carries cargo, goods, and materials from one port to another. Thousands of cargo carriers ply the world's seas and oceans each year, handling the bulk of international trade. Cargo ships are usually specially designed for the task, often being equipped with cranes and other mechanisms to load and unload, and come in all sizes. Today, they are almost always built by welded steel, and with some exceptions generally have a life expectancy of 25 to 30 years before being scrapped.
Southwick is a former village and now a suburb on the north banks of the River Wear in the city of Sunderland in the county of Tyne and Wear, historically in County Durham.
In 1980–1981, Austin & Pickersgill shipyard in Sunderland built three cargo ships of type SD18 for the Pakistan National Shipping Corporation of Karachi. The type of ship was a development of the highly successful Liberty ship replacement, type SD14. [1] In the light of changing market conditions in the wake of the global containerization, the shipyard was unable to sell any further ships of this type. All three ships spent their entire periods of service with the Pakistan National Shipping Corporation.
Karachi is the capital of the Pakistani province of Sindh. It is the most populous city in Pakistan, and fifth-most-populous city proper in the world. Ranked as a beta world city, the city is Pakistan's premier industrial and financial centre and is considered as the cultural, economic, philanthropic, educational, and political hub of the country. Karachi is also Pakistan's most cosmopolitan city. Situated on the Arabian Sea, Karachi serves as a transport hub, and is home to Pakistan's two largest seaports, the Port of Karachi and Port Bin Qasim, as well as the Pakistan's busiest airport, Jinnah International Airport.
Liberty ships were a class of cargo ship built in the United States during World War II. Though British in concept, the design was adapted by the United States for its simple, low-cost construction. Mass-produced on an unprecedented scale, the Liberty ship came to symbolize U.S. wartime industrial output.
Murree sank in 1989 in a force 10 gale in the English Channel, the other two ships, Ayubia and Kaghan were scrapped at Gadani Beach in 2001 and 2004 respectively.
SD18 ships had aft superstructure and machinery, and four cargo holds with a capacity totalling 24,345 cubic metres (859,700 cu ft) grain (i.e. loose material). The most forward cargo hold had a hatch with McGregor single-pull hatch covers, the other three cargo holds had double hatches, which were also sealed with McGregor single-pull hatch covers. [2]
Cargotec Oyj is a Finnish company that makes cargo-handling machinery for ships, ports, terminals and local distribution. Cargotec was formed in June 2005 when Kone Corporation was split into two companies to be listed: Cargotec and new KONE.
Their cargo-handling gear comprised six derricks, two of 35t and four of 25t. [2]
A derrick is a lifting device composed at minimum of one guyed mast, as in a gin pole, which may be articulated over a load by adjusting its guys. Most derricks have at least two components, either a guyed mast or self-supporting tower, and a boom hinged at its base to provide articulation, as in a stiffleg derrick.
The tonne, commonly referred to as the metric ton in the United States, is a non-SI metric unit of mass equal to 1,000 kilograms; or one megagram (Mg); it is equivalent to approximately 2,204.6 pounds, 1.102 short tons (US) or 0.984 long tons (UK). Although not part of the SI, the tonne is accepted for use with SI units and prefixes by the International Committee for Weights and Measures.
Power was produced by a single Sulzer RND68M two-stroke diesel engine, made under licence by Clark Hawthorn. The engine was directly coupled to the fixed pitch propeller and had an output of 8,385 kW (11,244 hp) MCR, propelling the ship at a speed of 15.75 knots (29.17 km/h; 18.12 mph). At the end of the 1980s Ayubia's main engine was replaced with a new engine of the same design built by Hitachi Zosen. [2] The onboard electricity was produced by three auxiliary diesel engines, each producing 450 kVA.
Sulzer Ltd. is a Swiss industrial engineering and manufacturing firm, founded by Salomon Sulzer-Bernet in 1775 and established as Sulzer Brothers Ltd. in 1834 in Winterthur, Switzerland. Today it is a publicly traded company with international subsidiaries. The company's shares are listed on the Swiss Stock Exchange.
R. & W. Hawthorn Leslie and Company, Limited, usually referred to as Hawthorn Leslie, was a shipbuilder and locomotive manufacturer. The company was founded on Tyneside in 1886 and ceased building ships in 1982.
Hitachi Zosen Corporation is a major Japanese industrial and engineering corporation. It produces waste treatment plants, industrial plants, precision machinery, industrial machinery, steel mill process equipment, steel structures, construction machinery, tunneling machines, and power plants. Despite its name, Hitachi Shipbuilding no longer builds ships, having spun this business off in 2002.

The Victory ship was a class of cargo ship produced in large numbers by North American shipyards during World War II to replace losses caused by German submarines. They were a more modern design compared to the earlier Liberty ship, were slightly larger and had more powerful steam turbine engines giving higher speed to allow participation in high speed convoys and make them more difficult targets for German U-boats. A total of 531 Victory ships were built.
A bulk carrier,bulk freighter, or colloquially, bulker is a merchant ship specially designed to transport unpackaged bulk cargo, such as grains, coal, ore, and cement, in its cargo holds. Since the first specialized bulk carrier was built in 1852, economic forces have led to continued development of these ships, resulting in increased size and sophistication. Today's bulk carriers are specially designed to maximize capacity, safety, efficiency, and durability.
Bremer Vulkan AG was a prominent German shipbuilding company located at the Weser river in Bremen-Vegesack. It was founded in 1893 and closed in 1997 because of financial problems and mismanagement.
Type C1 was a designation for small cargo ships built for the U.S. Maritime Commission before and during World War II. The first C1 types were the smallest of the three original Maritime Commission designs, meant for shorter routes where high speed and capacity were less important. Only a handful were delivered prior to Pearl Harbor. But many C1-A and C1-B ships were already in the works and were delivered during 1942. Many were converted to military purposes including troop-transports during the war.
William Doxford & Sons Ltd, often referred to simply as Doxford, was a British shipbuilding and marine engineering company.
A trunk deck ship is a type of merchant ship with a hull that was stepped inward in order to obtain more favourable treatment under canal toll rules then in effect. As those tolls were set by net tonnage, a measure of volume, and as the tonnage rules did not account for all of the cargo space of such vessels, trunk deck ships incurred lower tolls than more conventional ships of equivalent capacity. When the measurement rules were changed, the type was no longer built.
A CHANT was a type of prefabricated coastal tanker which was built in the United Kingdom during the Second World War due to a perceived need for coastal tankers after the invasion of France. Some CHANTs were adapted to carry dry cargos. These were known as the Empire F type coasters.
Empire Chaucer was a 5,970 GRT cargo ship which was built in 1942 by William Pickersgill & Sons Ltd, Sunderland. She was built for the Ministry of War Transport (MoWT). Completed in May 1942, she had a short career, being torpedoed and sunk by U-504 on 17 October 1942.
Type N3-S ships were a Maritime Commission small coastal cargo ship design to meet urgent World War II shipping needs, with the first of the 109 N3, both steam and diesel, type hulls delivered in December 1942.
