IMPROVING ADVANCE TRANSFER TECHNIQUE: MANOEUVRING ANALYSIS USING A BULK CARRIER SHIP WHILE IN BALLAST CONDITION

Abstract

A wheel over point is specified on the charted courses in a voyage plan to indicate the point at which the ship must change direction. A late course alteration would result in an overrun of the intended course line, which can be observe by the expansion of cross-track distance. The wheel over point may be computed using the advanced transfer technique. Through a practical assessment of ATT, the research was able to identify a few gaps. The data included in the manoeuvring characteristics, particularly advance and transfer, were then utilised to develop an IATF capable of bridging the gaps. Following that, a manoeuvring study was conducted and data, including the cross-track distance, were acquired. Compliance with cross track limits and percentage change were utilised to validate the simulation analysis findings. The results demonstrated that the enhanced mathematical model was capable of providing better track keeping and was thus suited for use onboard a cargo ship.
