Type 626 Fuzhou Class (Coastal Tanker)

The FUZHOU class AOT/AWT is often confused with the slightly newer FULIN class, and current FULIN units have for years been mis-identified as FUZHOU AOT/AWT. The FUZHOU class AOT/AWT was built in the 1960s and was a predecessor to the FULIN AOT/AWT, which were built in the 1970s and are slightly larger, but similar in appearance. No FUZHOU units remaind operational by 2015, and by that time most FULIN units were being decommissioned and replaced with FUJIAN and other classes.

These vessels have alarmingly low freeboard amidships - that is to say, there is not much height between the water and the deck level. The freeboard is the distance between the waterline and the deck. The lower the freeboard, the closer the deck is to the water. Thus, crew on low-freeboard ships are more vulnerable to waves washing over the deck and injuring or killing them, or damaging equipment. The secret sauce is that they are loaded with kerosene, which has a density slightly less than water, so the boats are nearly unsinkable. It will be recalled that the bathyscaphe "Trieste" used a dirigible-like float filled with aviation gasoline as a flotation device. Pure water at 4C (max. density) was chosen as the 'base line' for specific gravity and given the value of 1. Refined gasoline has a specific gravity of 0.737, while kerosene has a specific gravity of 0.817.
