Athens-based Diana Shipping Services S.A. has used Bureau Veritas’(BV) SEECAT energy simulation software to ascertain the energy performance of three capsize bulk carriers.
The aim of the BV SEECAT software is to enable ship owners and operators to verify the effectiveness of any measures that are implemented to increase energy efficiency on-board.
Following the assignment of BV’s Ship Energy Efficiency Management Plan (SEEMP) notation to the ships, BV has reviewed it for compliance with the International Maritime Organization’s (IMO) Resolution MEPC.213(63) that sets out Guidelines For The Development Of A Ship Energy Efficiency Management Plan.
Intermediate surveys will be carried out by BV surveyors to ensure that records of key performance indicators (KPIs) defined in the SEEMP are properly kept on board. The company has been provided with a software tool for calculation and recording of the Energy Efficiency Operational Indicator (EEOI) developed locally by the Piraeus Tecnitas team.
Using the BV SEECAT software, BV Piraeus validated the measures in the SEEMP. Using SEECAT, a model was created showing the ship’s energy flow system, with modules for all energy consumers including the main engine, auxiliary engines and boiler and data for the power curve taken from sea trials records.
Data was then calibrated using real voyage measurements provided by Diana Shipping Services S.A. SEECAT then provided the ability to establish several operational scenarios, including the comparison of fuel consumed, emissions such as CO2, sulphur oxides (SOx) and nitrogen oxides (NOx) between voyages and at normal speed or slow steaming.
