Study on Maximum Power Limitation of Gillnet Fishing Vessels Based on EEXI [PDF]

Israeli Journal of Aquaculture - Bamidgeh
To address issues such as insufficient fishing vessel data records, low energy efficiency, and high emissions, this study constructs and validates a predictive model for the maximum power limitation of fishing vessels. Using gillnet fishing vessels as a case study, the Energy Efficiency Existing Ship Index (EEXI) reference line formula for gillnet ...

Optimizing Maritime Energy Efficiency: A Machine Learning Approach Using Deep Reinforcement Learning for EEXI and CII Compliance

Sustainability
The International Maritime Organization (IMO) has set stringent regulations to reduce the carbon footprint of maritime transport, using metrics such as the Energy Efficiency Existing Ship Index (EEXI) and Carbon Intensity Indicator (CII) to track progress. This study introduces a novel approach using deep reinforcement learning (DRL) to optimize energy

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.
