Mooring Load Analysis during Ship to Ship Transfer Operations/Анализ нагрузки на швартовы при перекачке нефти/газа с судна на судно

Книга на английском языке.
Ship-to-Ship (STS) transfer operations take place under varying environmental conditions, adding to the complexity and risks associated with such transfers. Despite best efforts, mooring line failures are still a leading cause of incidents during transfers, potentially causing harm to people and environment and jeopardising the integrity of ships. This study aims to support stakeholders in making their own assessments to determine suitable weather criteria and ascertain an appropriate weather window for STS operations. This study, conducted by HR Wallingford in collaboration with OCIMF, also supports the KPIs listed under Element 5 of STS Service Provider Management and Self Assessment. These can be used to do location specific risk assessment and to determine safe operating environment limits, and a suitable weather window for ship to ship cargo transfer operations, as may be needed. The current study used advanced mooring line load simulation technology for enhanced assessment of mooring line loads under varying environmental conditions for a variety of ship-type combinations, including LPG and LNG carriers.
