A dry dock is a narrow basin or vessel that can be flooded to allow a load to be floated in, then drained to allow that load to come to rest on a dry platform. Dry docks are used for the construction, maintenance, and repair of ships, boats, and other watercraft.
Concrete ships are built primarily with ferrocement hulls, reinforced with steel bars. This contrasts against more traditional materials, such as pure steel or wood. The advantage of ferrocement construction is that materials are cheap and readily available, while the disadvantages are that construction labor costs are high, as are operating costs. During the late 19th century, there were concrete river barges in Europe, and during both World War I and World War II, steel shortages led the US military to order the construction of small fleets of ocean-going concrete ships, the largest of which was the SS Selma. United States Maritime Administration (MARAD) designation for concrete ships-barges was Type B ship. Few concrete ships were completed in time to see wartime service during World War I, but during 1944 and 1945, concrete ships and barges were used to support U.S. and British invasions in Europe and the Pacific. Since the late 1930s, there have also been ferrocement pleasure boats.
The lighter aboard ship (LASH) system refers to the practice of loading barges (lighters) aboard a bigger vessel for transport. It was developed in response to a need to transport lighters, a type of unpowered barge, between inland waterways separated by open seas. Lighters are typically towed or pushed around harbors, canals or rivers and cannot be relocated under their own power. The carrier ships are known variously as LASH carriers, barge carriers, kangaroo ships or lighter transport ships.

The Black Sea Shipyard is a shipbuilding facility in Mykolaiv, Ukraine, on the southern tip of the Mykolaiv peninsula. It was founded in 1895 by Belgian interests and began building warships in 1901. At the beginning of World War I in 1914, it was one of the largest industrial facilities in the Russian Empire. The shipyard was moribund in the first decades of the Soviet Union until the Soviets began building up their fleet in the 1930s and it began building surface warships as well as submarines. The yard was badly damaged during World War II and took several years to be rebuilt. Surface warship construction temporarily ended in the mid-1950s before being revived in the mid-1960s and submarines were last built in the yard in late 1950s. The Black Sea Shipyard built all of the aircraft carrying ships of the USSR and Russia and continued before the 2022 Russian invasion of Ukraine to build large commercial ships.

The Type B ship is a United States Maritime Administration (MARAD) designation for World War II barges. Barges are very low cost to build, operate and move. Barges were needed to move large bulky cargo. A tug boat, some classed as Type V ships, could move a barge, then depart and move on to the next task. That meant the barge did not have to be rushed to be unloaded or loaded. Toward the end of World War 2, some ships that had not been completed in time for the war were converted to barges. US Navy barges are given the prefix: YWN or YW. Due to shortage of steel during World War II, concrete ship constructors were given contracts to build concrete barges, with ferrocement and given the prefix YO, YOG, YOGN. Built in 1944 and 1945, some were named after elements.
