Athens-based Diana Shipping Services S.A. has worked with Bureau Veritas to assess the energy performance of three capesize bulk carriers using BV’s SEECAT energy simulation software.
The vessels have then been assigned BV’s additional notation SEEMP. This notation denotes that the vessel’s Ship Energy Efficiency Management Plan has been reviewed by BV for conformance with the requirements of IMO Resolution MEPC.213(63). The vessels will be audited during intermediate surveys by BV surveyors to ensure that records of 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.
BV Piraeus validated the measures in the SEEMP using the BV SEECAT software. A model of the vessel’s energy flow system was created in SEECAT, with modules for all energy consumers including the main engine, auxiliary engines and boiler, as well as data for the power curve taken from sea trials records. The data was calibrated using real voyage measurements provided by Diana Shipping Services S.A. By performing time domain simulation in SEECAT, several operational scenarios were examined, including comparison of fuel consumption and CO2, SOx and NOx emissions between voyages performed at normal design speed or slow steaming. Diana Shipping Services S.A. now has access to a sophisticated tool that can verify the effectiveness of any measures taken to increase the energy efficiency of its vessels’ operation.
