Additional Information:This module builds on the knowledge gained from the level 4 module 4307MECH Mechatronics 1 and is designed to give Marine Engineering students a comprehensive understanding of the electrical systems, sensors and control equipment utilised in the marine engineering sector. It provides partial fulfilment of the MCA Certificate of Competency meeting STCW Reg - III/1 Engineer Officer of the Watch requirements. The focus of the module is concerned with the safe and efficient operation of plant, the correct use of equipment provided for the safety of the ship and the protection of the environment. This module incorporates content that relates to the following UN Sustainable Development Goals : SDG7 - This module considers the generation, control and management of affordable, reliable, sustainable and modern marine energy systems. SDG9 – This module provides students with an understanding of developing resilient electrical infrastructure and the adoption of innovative marine electrical plant in regards to energy consumption and electrical waste (IMO MARPOL Annex VI – e-waste). SDG14 – This module considers the sustainability and conservation of the marine environment by the use of efficient shipboard electrical systems.
