At the initial concept design stage, we provide the following support:
As part of the EEDI preliminary verification, accurate estimates of EEDI can be provided accounting for the following design considerations:
Required value for type of ship, EEDI phase
Speed-power curve for specified EEDI loading condition
Main and auxiliary engine characteristics
Ship’s cargo capacity (deadweight)
Guidance in the following:
Planning of towing tank (model) tests to optimize the scope required to meet EEDI preliminary and final verification requirements including the use of energy-saving devices
The evaluation of tank test results for correlation with measurements from full-scale trials
Assistance in meeting the IMO MEPC requirements for minimum propulsion power taking into consideration the constraints of the required EEDI values for the type of ship. We provide both Level 1 and Level 2 assessments for bulk carriers and tankers
At the end of construction/sea trials and prior to delivery, we provide the following support:
Guidance in the planning and conduct of speed trials required for EEDI verification as well as attendance on board.
Independent speed trial analysis to confirm speed-power characteristics in calm water from which we derive the vessel’s EEDI reference speed. We can also provide independent assessment of the vessel’s speed-power characteristics in specified contract conditions.
Verification of the attained EEDI using the final (as-built) engine, vessel and speed-power characteristics. As recognition of meeting the IMO MEPC requirements, we issue the IEE certificate.
The “International Convention for the Prevention of Pollution from Ships (MARPOL 73/78)” keeps the important role in controlling the harmful gasses emissions to the environment from navigation activities. It was adopted in July 2011 and added a new Chapter 4 with Regulations on Energy Efficiency for ships to MARPOL Annex VI through the “Energy Efficiency Design Index (EEDI) for new ships”, and “the Ship Energy Efficiency Management Plan (SEEMP) for all ships”. On the other hand, Annex VI (MARPOL 73/78) also added the new definitions and the requirements for survey and validated of the formats for “the International Energy Efficiency (IEE) Certificate”. Furthermore, the role of new ships energy efficiency managements is very significant so contributing to the later ships operation through EEDI index. In this aim, the articles has presented the definitions, regulations following MARPOL Convention as well as calculate the EEDI index and assess this working of energy efficiency managements for new ship M/V Jules garnier.
