A CFD-based evaluation of ship speed at EEXI draft

IOP Conference Series: Materials Science and Engineering, 2023
Abstract This paper presents a simulation of ship speed for an existing containership at EEXI draft using Computational Fluid Dynamics (CFD). The simulation is divided into two steps namely (a) the numerical prediction of ship performance at model scale, and (b) the extrapolation of results to full scale.

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.

Evaluation of Energy Efficiency Existing Ship Index (EEXI) on Container Ship in Indonesian Shipping

IOP Conference Series: Earth and Environmental Science, 2023
Abstract CO2 has been one of the biggest contributors of Green House Effect, crippling the ozone of our own earth over the years. Ships, as the biggest transportation mode in the world, estimated to produce 1,046 millioin tonnes of CO2 approximately 3,3% from the total of CO2 emission across the globe.

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 ...

On energy efficiency of tankers: EEDI, EEXI and CII

Ocean Engineering
This paper aims to extensively analyze the energy efficiency of large tanker fleets, focusing on their compliance with the International Maritime Organization (IMO) requirements through the evaluation of design and operational indices. Despite an increase in energy efficiency studies, few have assessed large tanker fleets and their subgroups ...
