Abstract

Technical Analysis of Azimuth Thruster and Conventional Systems

Highlights

  • Offshore industry demands a strong shipping fleet to meet the logistics needs of goods and people movement from one place on the mainland to reach another place on the sea or offshore and vice versa

  • The vessel named TOPAZ JUMEIRAH that uses a conventional system works as an Offshore Support Vessel Al-Shaheen Oilfield, Qatar, showing the results that the motion is less than optimal, especially in conditions of oilfield by the number of the platforms and the distance adjacent to each other

  • Manoeuvring experiments using conventional systems and azimuth thrusters on first, second, and third trials by conversion of the coordinates on Global Positioning System (GPS) device produce Tactical and Final diameter as shown in Table 2 as follows: Finals and tactical diameter difference between the conventional and the azimuth thruster look quite significant. This showed that the use of azimuth thruster produces tactical and final diameter smaller than conventional system

Summary

Introduction

Offshore industry demands a strong shipping fleet to meet the logistics needs of goods and people movement from one place on the mainland to reach another place on the sea or offshore and vice versa. The ability to take maneuver of a ship is indispensable when operating in waters, especially the entry and exit areas of offshore oil drilling in Qatar. The vessel named TOPAZ JUMEIRAH that uses a conventional system works as an Offshore Support Vessel Al-Shaheen Oilfield, Qatar, showing the results that the motion is less than optimal, especially in conditions of oilfield by the number of the platforms and the distance adjacent to each other. This has implications for the duration and ship operation which will have an impact on operational costs. The application of technology and control of ships using the azimuth thruster with fixed propeller and thrust capability of the propeller which can rotate 360° indicates that the performance of the maneuver become easier
