abstract = {The methodology and procedures are discussed on designing merchant ships to achieve fully-integrated and optimized hull-propulsion systems by using asymmetric aftbodies. Computational Fluid Dynamics (CFD) has been used to evaluate the powering performance through massive calculations with automatic deformation algorisms for the hull forms and the propeller blades. Comparative model tests of the designs to the optimized symmetric hull forms have been carried out to verify the efficiency gain. More than 6% improvement on the propulsive efficiency of an oil tanker has been measured during the model tests. Dedicated sea-trials show good agreement with the predicted performance from the test results.},

abstract = {The speed/power characteristics of ships have always been at the core of ship design. To prove contractually agreed values, speed trials are conducted by the yard prior to delivery of the ship to the owner. In the past schedule integrity of the vessel was often the most important factor for the speed requirement. Today, owners and operators are keen to reduce fuel consumption to decrease operational costs. So far a variety of methods for conducting and analyzing speed/power trials have been used by shipyards. With the assistance of the Sea Trial Analysis-Joint Industry Project, ITTC developed guidelines for the execution and analysis of speed/power trials compliant with IMO EEDI. The need to reduce fuel costs and exhaust gas emissions including the upcoming environmental regulations such as EEOI by IMO urge for reliable monitoring of ship performance in service conditions. This requires accurate information of the speed through water. Although the speed log is one of the oldest instruments on board it is not considered the most reliable one. Results of an extensive monitoring campaign on board a 1800 TEU container vessel equipped with six speed logs within SPA-JIP will be presented. The state of art of performance monitoring will be presented.},
