The paper analyses and addresses various tanker ship survey regimes, determining a certain amount of overlapping between specific survey regimes. The results of the study indicate that there are inconsistencies in the frequency of surveys and over inspections of some ships. These uncoordinated surveys affect the costs as well as the mental and physical condition of the crew. The mentioned indica tes the necessity of the overall tanker survey rationalization, having in mind that the rationalization must not have the negative impact on the safety of the ship. In this paper, the authors proposes the implementation of the unified tanker survey model that would integrate components of all survey regimes. The comprehensive analysis of the risks arising from non compliance, oversights or absence of surveys, have resulted in setting up the optimal time needed to conduct surveys with respect to the technical, technological and economic specifications of the ship. The implementation of the unified survey would eliminate the negative effects found during present surveys and enhance the safety of the ship as well as the quality of the management.
