Exergy efficiency and EEXI analysis of a marine power plant at partial load conditions

Proceedings of the Institution of Mechanical Engineers, Part M: Journal of Engineering for the Maritime Environment, 2023
Energy efficiency and environmental protection are becoming more important in the world. Almost 90% of the world trade is carried by sea which makes energy efficiency very important for the maritime sector. Exergetic method is a powerful scientific tool for measuring energy efficiency. The ships are not always cruising at maximum load conditions.

The effect of EEXI regulation to the dynamics of bulk shipping market

2023
Η ναυτιλιακή βιομηχανία, ο ακρογωνιαίος λίθος των παγκόσμιων μεταφορών εμπορευμάτων, παλεύει με την επιτακτική ανάγκη των κανονισμών για την απανθρακοποίηση και τη μείωση των εκπομπών ρύπων. Αυτή η μελέτη θα επικεντρωθεί στον κανονισμό για τον υφιστάμενο δείκτη ενεργειακής απόδοσης πλοίων (EEXI) και το αντίκτυπο που ενδεχομένως μπορεί να έχει στη ...

Implications of IMO EEXI compliance and carbon intensity reduction in shipping operations

2023
The aim of the present research is to analyze the two new IMO indexes, the EEXI and CII, as well as the implications of which will affect the operational processes of a shipping company and the efficiency of the ship. Firstly, this paper describes the main Greenhouse Gases and their impact to the environment, as well as the contribution of Shipping ...

UNVEILING THE JOURNEY OF MARITIME ENERGY EFFICIENCY: A DEEP DIVE INTO EEDI, EEXI, CII, POTENTIAL CII REGULATION ENHANCEMENTS, AND PERSISTENT CHALLENGES

International Journal of Maritime Engineering
The Energy Efficiency Design Index (EEDI) and the Energy Efficiency Existing Ship Index (EEXI), two crucial regulations in the maritime sector, are examined in detail in this paper. This study aims to understand the complexities of these restrictions and analyse how the Energy Efficiency Operational Indicator (EEOI) could be used to improve the way the

EEXI Regulations and Energy Saving Devices

Energy Efficiency Design Index (EEDI) has been successfully implemented for over a decade in the maritime industry. The EEDI strictly concerns only the newly built vessels and is expected to strengthen the energy efficiency requirements every ten years until 2050.
