Development of courses for the maritime training institute of the Shipping Corporation of India

The, Shipping Corporation of India ltd. (SCI), is a public sector shipping organisation, registered at Bombay, owning and managing about 176 vessels of nearly six million tonnes DWT. In 1973, in order to meet the training needs of fleet and shore personnel, a training department was formed. A few short courses were developed and conducted by hiring space in various colleges and institutes at Bombay. With the growing needs of SCI, in regard to training of personnel and taking into account the requirements of, International Convention on Standards of Training, Certification and Watchkeeping for Seafarers, 1978 (STCW 78), the idea was mooted to set up an, SCI Maritime Training Institute . Land was acquired at Powai, a suburb of Bombay, in 1982/83 and construction of the institute, has commenced in March 1985. It is expected that the institute would be functional by the end of 1986. In this paper, an attempt has been made to plan and develop the various courses which would be required to be conducted at the SCI Maritime Training Institute

ErgoShip 2021 – Maritime artikler

Welcome to the special issue dedicated to the conference Ergoship 2021! The editorial committee are proud to present a selection of papers from Ergoship 2021 and a few invited papers within the topic of maritime Human Factors. The first Ergoshipwas held in Gothenburg in 2011 to create a meeting place for researchers in maritime Human Factors. The conference has lived on and was held in Australia 2016, in Haugesund 2019 and in South Korea 2021. We wish we could all have met in person, but this time it was not to be. Nevertheless, we look forward to sharing these papers with you and hope we can drive this field forward together. Enjoy the papers from a small but passionate group of contributors. The authors and the audience make this recurring conference special

Aeolus Ocean -- A simulation environment for the autonomous COLREG-compliant navigation of Unmanned Surface Vehicles using Deep Reinforcement Learning and Maritime Object Detection

Heading towards navigational autonomy in unmanned surface vehicles (USVs) in the maritime sector can fundamentally lead towards safer waters as well as reduced operating costs, while also providing a range of exciting new capabilities for oceanic research, exploration and monitoring. However, achieving such a goal is challenging. USV control systems must, safely and reliably, be able to adhere to the international regulations for preventing collisions at sea (COLREGs) in encounters with other vessels as they navigate to a given waypoint while being affected by realistic weather conditions, either during the day or at night. To deal with the multitude of possible scenarios, it is critical to have a virtual environment that is able to replicate the realistic operating conditions USVs will encounter, before they can be implemented in the real world. Such "digital twins" form the foundations upon which Deep Reinforcement Learning (DRL) and Computer Vision (CV) algorithms can be used to develop and guide USV control systems. In this paper we describe the novel development of a COLREG-compliant DRL-based collision avoidant navigational system with CV-based awareness in a realistic ocean simulation environment. The performance of the trained autonomous Agents resulting from this approach is evaluated in several successful navigations to set waypoints in both open sea and coastal encounters with other vessels.
