Core Responsibilities

Primary Functions

Perform comprehensive diagnostic tests and troubleshooting on marine diesel main propulsion engines (e.g., EMD, Caterpillar, Cummins, MTU) to identify and resolve performance issues and malfunctions.
Execute major and minor repairs, overhauls, and component replacements on engines, reduction gears, clutches, and other powertrain components.
Conduct routine and preventative maintenance according to manufacturer specifications and company schedules, including oil changes, filter replacements, and fluid analysis.
Service and repair auxiliary machinery, including generators, air compressors, pumps (bilge, fire, fuel transfer), and deck machinery like winches and cranes.
Diagnose and repair complex marine hydraulic systems, including steering gear, tow winch controls, and other hydraulically-actuated equipment.
Troubleshoot and repair shipboard electrical systems, covering AC and DC circuits, motor controls, alarm panels, and navigation light systems.
Perform welding, fabrication, and machining tasks as needed for structural repairs and custom component fitting.
Inspect, service, and repair propulsion components, including shafts, propellers, seals, and bearings to ensure optimal performance and integrity.
Respond to and resolve unplanned equipment failures and casualties, often under time-sensitive conditions to minimize vessel downtime.
Utilize specialized diagnostic tools such as vibration analysis equipment, thermal imagers, and electronic service tools to proactively identify potential failures.
Read and interpret complex technical manuals, blueprints, and electrical/hydraulic schematics to guide repair and maintenance activities.
Ensure all work is performed in strict compliance with company safety policies, environmental regulations, and US Coast Guard (USCG) standards.
Conduct operational tests and vessel trials post-repair to verify functionality and ensure all systems perform to specifications.
Align engines and shafts to precise tolerances to prevent excessive vibration and wear on drivetrain components.
Maintain and repair HVAC, refrigeration, and sanitation systems onboard the vessels to ensure crew comfort and compliance.

Secondary Functions

Maintain meticulous and accurate records of all maintenance, repairs, parts usage, and labor time in the company's Computerized Maintenance Management System (CMMS).
Assist in managing the inventory of spare parts, tools, and supplies, and recommend procurement of necessary items to prevent stock-outs of critical components.
Collaborate closely with vessel crews, Port Captains, and Port Engineers to schedule maintenance and communicate vessel status effectively.
Participate in and contribute to regular safety meetings, job hazard analyses, and incident investigations.
Provide technical guidance and mentorship to junior technicians, apprentices, or vessel engineering crew.
Support vessel dry-docking projects by planning and executing major overhaul work scopes and inspections.
Recommend improvements to maintenance procedures, equipment, or vessel systems to enhance reliability and efficiency.
Stay current with emerging marine technologies, new engine models, and evolving regulatory requirements.
