In 1991 Ching Fu brought the traditional Taiwanese tuna purse seiner building industry to a new level. We obtained exclusive license from Campbell Shipyards, San Diego, USA (now known as MARCO Engineering) to build their 1500 CBM Super Pacific Class Tuna Purse Seiner in Taiwan.. The seiners built by Ching Fu have the same hull lines and general naval architecture as all other super seiners built by Campbell, including the same power package and helicopter. The ship's refrigeration systems are based on the Japanese method of freezing the tuna down to -30 degrees C. In order to achieve this, increased insulation was designed into each tuna tank, including wooden furring construction, giving these vessels a 'floating liner' configuration. This enables these Ching Fu ships to land the tuna directly to markets, rather than employing the US and European method of offloading to canneries. The yard's tuna purse seiner vessels were built under ABS classification..
