An Electrician on board a cruise ship is responsible for the maintenance, repair, and troubleshooting of all low and medium-voltage electrical systems across accommodation, engine, and hotel areas. Duties include maintaining electrical machinery, power distribution systems, drive and control systems, lighting, elevators, galley and laundry equipment, and mobile electrical devices. They install new components, diagnose and repair faults, and ensure all systems comply with safety, environmental, and ISM regulations. Electricians support emergency responses, follow Planned Maintenance System (PMS) tasks, assist with inventory counts, and contribute to a strong onboard safety culture by following HESS and company health protocols.
