Event details

The 2012 guidelines on Energy Efficiency Design Index (EEDI) for new ships (MEPC.212(63)) represent a major step forward in implementing the REGULATIONS ON ENERGY EFFICIENCY OF SHIPS. However, there are serious concerns regarding the sufficiency of propulsion power and of steering devices to maintain the manoeuvrability of ships in adverse conditions, hence the safety of ships. This gave reason for additional considerations and studies at IMO leading to 2013 Interim Guidelines for determining Minimum Propulsion Power To Maintain The Manoeuvrability Of Ships In Adverse Conditions (MEPC.232(65), 2013 and MEPC 262(68), 2015). These minimum power regulations only concern about under powering of tankers and bulkers above certain size: Is it not necessary to address all the different ship types and sizes within EEDI framework?

Speaker information

Dr Reddy Devalapalli, Lloyd's Register. Dr Reddy D N, Principal Specialist in the Strategic Research and Technology Policy Group (SRTP), has around 30 years of experience in marine field, including fifteen years in Defence R&D Organisation of India undertaking several hydrodynamic studies on ships and submerged bodies. Within LR, he has been involved in applications of CFD techniques to sloshing, slamming and other hydrodynamic studies for development of rules and procedures. In SRTP group he is responsible for identifying technical issues, analysing their solutions and their implications for the Organisation and also assist in review of LR Marine Technology Policy. He was actively involved in recent IACS studies developing '2013 guidelines on Minimum Propulsion Power To Maintain The Manoeuvrability Of Ships In Adverse Conditions'.
