Cargo control room : ウィキペディア英語版 | Cargo control room
The cargo control room, CCR, or cargo office of a tankship is where the person in charge (PIC) can monitor and control the loading and unloading of the ship's liquid cargo. Prevalent on automated vessels, the CCR may be in its own room, or located on the ship's bridge.〔Huber 2001, p. 146.〕〔Huber 2001, p. 147.〕 Among other things, the equipment in the CCR may allow the person in charge to control cargo and stripping pumps, control and monitor valve positions, and monitor cargo tank liquid levels. ==History==
Cargo control rooms began to appear on U.S.-flag tankers in the mid-1960s.〔Gordon, 1993, p. 128.〕 Prior to this time, valves were operated manually on deck by reach rods and liquid levels were monitored by a roving watch consisting of the mate and seamen on watch.〔 The use of computers in the cargo control room began in the 1980s.〔 As technology developed, computerized systems began to centralize tasks such as cargo control ''per se'', tank level monitoring, and real-time computation of hull stress information in the cargo control room.〔
