REPORT TO THE PRESIDENT ON AN EVALUATION OF DEVICES AND TECHNIQUES TO IMPROVE MANEUVERING AND STOPPING ABILITIES OF LARGE TANK VESSELS
This report is the final in a series of five that were initiated by the President in his 17 March 1977 message to Congress on the reduction of marine oil pollution. The report presents the basic definitions of maneuvering and stopping abilities and an assessment of the maneuvering and stopping abilities of existing tank vessels as a function of deadweight, compared to those of dry cargo vessels. Using the methods for evaluating maneuvering abilities that are outlined, various devices that have been proposed were examined. The initial evaluation was based on the degree of improvement in the maneuvering ability, the cost and the effect on the design of the vessel for each device. A mathematical (simulation) model was employed to further evaluate the most promising devices. A description of each operational technique has been included. The evaluation of the operational techniques was performed primarily by reporting on various full scale tests. The findings indicate that good maneuvering characteristics can be achieved for tank vessels, but without some guidance or requirement, this is not generally considered in the design cycle for new ship construction.
