Abstract
The article presents the main results of the scientific research work aimed at analyzing the possibility and computational justification of an alternative design solution for a berth-connected reinforced concrete storage vessel for oil products. The design is made in accordance with the requirements of resolutions MEPC.110(49) andMEPC.311(73) taking into account the special aspects of operation. The vessel is designed without a double bottom and double sides, which does not meet the requirements of 19.3.1 and 19.3.6 of MARPOL 73/78 Annex 1. The justification of alternative design solution safety has been made by calculation of the pollution prevention index. Such index is determined on the basis of oil spill parameters in the event of a side and bottom damage of the vessel hull in accordance with resolution MEPC.110(49). Additionally, calculations of the hull strength in a relatively mild collision have been carried out, together with assessment of the occurrence probability of such incident. Based on the above, a risk assessment have been carried out and decisions on the safety of an alternative vessel design solution for the assigned operation purposes have been made.
Keywords: berth-connected reinforced concrete vessel, oil spill, pollution prevention, ship collision, statistics, severity of consequences, risk assessment.
