Core Responsibilities

Primary Functions

Install, route, and secure all types of marine-grade electrical cables and wiring harnesses through complex ship structures, ensuring adherence to strict maritime safety codes and engineering blueprints.
Terminate and connect wires and cables to a wide variety of electrical equipment, including circuit breakers, transformers, switchboards, controllers, and junction boxes.
Read, interpret, and work from complex technical documents such as electrical schematics, wiring diagrams, installation drawings, and manufacturer's manuals to guide installation and repair activities.
Perform comprehensive diagnostic tests and troubleshooting on complex electrical systems and components to identify faults, determine the root cause of failures, and establish an effective repair plan.
Execute repairs and component replacements on a diverse range of marine electrical equipment, including AC/DC motors, generators, power distribution panels, and automated control systems.
Install and connect power supplies for a variety of shipboard systems, encompassing communications, navigation, electronic controls, and fire alarm and safety systems.
Conduct preventative maintenance routines on all shipboard electrical systems to ensure their long-term reliability and to minimize the risk of operational failures at sea.
Utilize a wide array of specialized electrical testing equipment, such as multimeters, meggers, oscilloscopes, and clamp-on ammeters, to test, calibrate, and validate system performance.
Perform final system checks and operational tests on newly installed or repaired electrical equipment to ensure it functions according to design specifications and is safe for operation.
Mount and install main electrical components, such as switchboards, lighting fixtures, power outlets, and control panels, ensuring they are properly secured and grounded.
Ensure all electrical work complies with the stringent standards and regulations set forth by maritime classification societies like the American Bureau of Shipping (ABS), U.S. Coast Guard (USCG), and SOLAS.
Adhere rigorously to all safety protocols, particularly Lock-Out/Tag-Out (LOTO) procedures, when de-energizing and working on electrical systems to prevent accidents.
Maintain detailed logs and records of all maintenance activities, repairs, and installations performed, contributing to the vessel's official maintenance history.
Collaborate closely with other trades, such as pipefitters and shipfitters, to coordinate the installation of electrical systems around other vessel infrastructure.
Inspect and test shipboard electrical equipment for insulation resistance, continuity, and proper grounding to prevent electrical shock and fire hazards.
Fabricate and install electrical support structures, such as cable trays, conduits, and equipment foundations, as needed to support system installations.
Set up and manage temporary and shore power connections for vessels in dock, ensuring a safe and stable power supply for shipboard operations and repair work.
Troubleshoot and repair programmable logic controllers (PLCs) and other automated systems that control machinery and vessel functions.
Respond to emergency electrical failures, quickly assessing the situation and implementing effective solutions to restore power and functionality in high-pressure situations.
Participate in sea trials to test and validate the performance of electrical systems under real-world operational conditions, making adjustments as necessary.

Secondary Functions

Support engineering teams by providing technical feedback, red-lining drawings with as-built conditions, and assisting in the development of new installation plans.
Contribute to the continuous improvement of departmental maintenance procedures, safety protocols, and standard operating practices.
Assist in managing inventory of electrical parts and components, recommending stock levels and sourcing materials for upcoming jobs.
Mentor and provide on-the-job training to junior electricians and apprentices, sharing technical knowledge and best practices.
