Comments
This CALM was installed offshore Kaohsiung, Taiwan in mid 1991 for Chinese Petroleum Corporation (CPC). This dual product terminal is designed to import crude oil with simultaneous bunkering service. This PLEM attaches the 56-in. and 16-in. subsea pipelines to two 24-in. crude oil hoses and a single 12-in. bunker hose. The 12.5m diameter CALM is anchored to the seafloor by six 4.5-in. chain legs and 18mt “Stevpris” high capacity drag anchors. The underbuoy hoses are arranged in a Lazy S configuration.
The terminal is designed to moor tankers up to 300,000 dwt.
