Sažetak
Since the introduction of the new chapter 4 within MARPOL Annex VI there is an ongoing discussion about the impact of this new regulation on newbuildings. These amendments introduced International Energy Efficiency (IEE) Certificate. In order to obtain it, a ship has to comply with the Energy Efficiency Design Index (EEDI) and Ship Energy Efficiency Management Plan (SEEMP) requirements. The proclaimed intention of IEE Certificate is to increase energy efficiency of ships. However, in practice the EEDI depends on various design parameters so it is not clear if the achieved improvements are as expected. So the aim of this paper is to analyze the EEDI impact on the ship design, for different ship types: bulk carriers, container ships, tankers and ro-ro passenger ships. The EEDI values of the above mentioned ship types are calculated and compared with the Required EEDI values in order to assess their energy efficiency performance. Then, the analysis of dominant design parameters for EEDI for different ship types is performed. The results of the analysis can help designers in smooth EEDI management and allow an insight to determine for selected ship types if the newbuildings can satisfy the EEDI requirements just barely (which means the EEDI requirement is set too strict), or if they have no problems in complying with the EEDI requirement (which can be indicator that the EEDI requirement is too lenient).
