US Navy Water Barge, YW-59, launched August 29, 1941 [1]

The Type B ship is a United States Maritime Administration (MARAD) designation for World War II barges. Barges are very low cost to built, operate and move. Barges were needed to move large bulking cargo. A tug boat could move a barge, then depart and move on to the next task. This meant the barge did not have to be rushed to be unload or loaded. Towards the end of the 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 WW2, Concrete Ship Constructors was given contracts to built concrete barge with the prefix YO, YOG, YOGN and some named after elements, built in 1944 and 1945. [2][3][4]

Freight Barges -YF - YFN[edit]

Most YFN barges were not self-propelled and most YF were self-propelled. A YFN could carry a load of 550 long tons. YFN were near shore with a steel hull. They worked in harbors, rivers and other protected waters. They were 110 foot long, with a 32-foot beam and maximum draft of 8 feet. [5][6]

Refrigerated Freight Barges YFR - YFRN[edit]

Most YFRN were not self-propelled and YFR were self-propelled. [7]

Concrete Barge[edit]

United Kingdom[edit]

  • Thames lighters, or dumb barge, were non-self-propelled barges. The original Thames barges are the sailing vessels, many were converted for the war. LB or landing barges were used, some had ramps added and were called LBR or Landing Barge, Ramped. Some had engines and rudder added to be called LBV or Landing Barge Vehicle. They were used for different task: Landing Barges Oiler (LBO), Water (LBW), Kitchen (LBK) and Emergency Repair (LBE), Landing Barges Flak (LBF) and Gun (LBG). There was also one Landing Barge Cable (LBC). Many were used to for supplies to Normandy.[39][40]

Current barge classes[edit]

Type B I barge hull is designed to carry products which require the maximum preventive design to ensure no uncontrolled release cargo to the water or atmosphere.

Type B II barge hull. Barge hulls classed as Type II are those designed to carry products which require substantial preventive measures to ensure no uncontrolled release cargo to the water or atmosphere. But if released to the water would not make a long lasting public hazard.

Type B III barge hull. Barge hulls classed as Type III are those designed to move products of minor hazard and thus need less degree of control.[41]
