The hydrodynamic comparison between a conventional and an Axe Bow frigate hull

The seakeeping behaviour of naval ships is an important factor for its operational effectiveness, as vessels with good seakeeping abilities are able to go to sea and successfully execute their missions despite possible adverse weather conditions. Hence, it is not surprising that the hydrodynamic assessment of a new frigate type hull forms is...

An experimental study on added resistance focused on the effects of bow wave breaking and relative wave measurements

The added resistance is a resistance component that is not yet satisfactorily predicted, although its accurate estimation is crucial-both from an environmental and economic point of view-from the design stage of a ship until its operation. One of the possible sources of overprediction is the occurrence of bow wave breaking. The first aim of...

The effect of bow wave breaking on added resistance

Stimulated by the energy efficiency indices introduced by the International Maritime Organization, the increased attention for the environment as well as economical pressures emphasize the relevance of accurate resistance estimation for ships. This leads to a particular interest for added resistance in waves, a resistance component that is...

Prediction of the added resistance in waves using CFD

Shipyards these days see an increase in customers that specify combined speed and seakeeping ability design requirements. This requires the shipyard to make a prediction of the additional installed power required to maintain a certain speed when waves are encountered. The additional required installed power is directly related to the average...

Influence of Bow-Wave Breaking on the Added Resistance of Fast Ships

The publication of the Energy Efficiency Design Index (EEDI) by the International Maritime Organization (IMO) has recently stimulated the accurate assessment of actual sea performance of ships, which is evaluated as added resistance in waves. However, a satisfactory consensus on the evaluation method has not yet been reached owing to uncertainty...
