In the face of a growing need for reduced emission of CO_2 from ships, which is equivalent to better fuel economy in ship operation, a simple and user-friendly index for ship performance evaluation alongside the technique has been developed. This newly developed technique results from a practical and brand new approach in combing a numerical calculation with a simplified tank test, striking the balance between the costs to be incurred for the tests and expected accuracy. The technique has been validated through tank tests conducted by major tank organizations and the numerical calculation by major shipbuilders. The data obtained through the measurement taking place onboard the commercially operational ships were also used to verify the evaluation technique. It is concluded that the evaluation technique developed is deemed as robust and valid. It is strongly hoped that the index as well as the evaluation technique will contribute to the increased construction of ships with better performance in actual sea and to the promotion of ship operation resulting in less CO_2 emission.
