• Corrosion survey is carried out for seventeen Caraka Jaya ships. The ships are general cargo and semi container ships of 3,000DWT and 3,650DWT built in first and second phases of Caraka Jaya project. The survey includes the plate thickness measurements and the data collection of previous inspection records. Collected data are from the points of main deck, tank top, bulkhead (cargo hold), bottom plate, bilge plate and side shell. Totally, 3,430 points of data are collected. Annual corrosion rate is calculated for respective locations and compared with other ships. It is found that the mean value of annual corrosion rate is about 0.12mm/year and this value is near to the corrosion rate of Class NK ships surveyed during the period between 1973 and 1978. The standard deviation of corrosion rate is little bit larger than that of Class NK ships.
