Defining Maritime 4.0: Reconciling principles, elements and characteristics to support maritime vessel digitalisation

open access: yesIET Collaborative Intelligent Manufacturing, Volume 3, Issue 1, Page 23-36, March 2021., 2021
Abstract As complex systems, maritime vessels generate and require the utilization of large amounts of data for maximum efficiency. Designing, developing, and deploying these systems in a digital world requires rethinking how people interact and utilize technology throughout all areas of the industry.

The Obligations of Single-Propeller Vessels at the Head-On Situation [PDF]

open access: yesTransNav, 2016
Manoeuvring characteristics of the vessels at the head-on situation are examined in this study. The meetings between the power-driven vessels are considered based on their propellers. These vessels can either have a single propeller or double propellers.
