🎯 Role Definition

A Marine Engineer is a highly skilled and licensed engineering professional responsible for the heart of any vessel: its propulsion, power generation, and auxiliary systems. This role is a dynamic blend of hands-on mechanical and electrical engineering, strategic asset management, and rigorous regulatory compliance. You are the technical authority onboard, ensuring the ship operates safely, efficiently, and reliably across the globe. From the main engines that drive the vessel to the life-support systems for the crew, the Marine Engineer's oversight is critical to mission success and the safety of everyone onboard. This position demands a unique combination of technical mastery, leadership, and resilience to solve complex problems in a challenging maritime environment.

Lateral Moves:

  • Naval Architect
  • Project Manager (Shipyard/New-builds)
  • Classification Society Surveyor

Core Responsibilities

Primary Functions

  • Oversee the safe and efficient operation and maintenance of the vessel's main propulsion machinery, including main engines, gearboxes, and propeller systems.
  • Manage all auxiliary machinery, such as diesel generators, air compressors, pumps, purifiers, and steering gear, ensuring optimal performance and reliability.
  • Direct and supervise the implementation of the vessel's Planned Maintenance System (PMS) to ensure all maintenance tasks are completed on schedule and documented correctly.
  • Conduct comprehensive troubleshooting and diagnostics to resolve complex mechanical, electrical, and hydraulic system failures, often under challenging time constraints.
  • Ensure the vessel's engineering operations are in strict compliance with international, flag state, and local regulations, including MARPOL, SOLAS, and the ISM Code.
  • Manage the engine room team, including assigning daily work duties, overseeing performance, and fostering a strong safety culture and teamwork environment.
  • Maintain meticulous records in the engine room logbook, oil record book, and other official documentation as required by company policy and maritime law.
  • Control and manage the inventory of spare parts, consumables, and tools, preparing requisitions and managing the engineering budget effectively.
  • Supervise and manage all bunkering, lube oil replenishment, and bilge/sludge disposal operations, ensuring procedures are followed safely and without environmental incident.
  • Plan, coordinate, and oversee major repairs, overhauls, and equipment installations, both at sea and during dry-docking or shipyard periods.
  • Operate and maintain the vessel's environmental protection systems, including oily water separators, sewage treatment plants, and incinerators, ensuring effluent standards are met.
  • Monitor and analyze vessel performance data, including fuel consumption and machinery efficiency, to identify opportunities for optimization and cost savings.
  • Prepare detailed technical reports, repair specifications, and dry-docking lists for the shore-based management team.
  • Ensure all engine room safety equipment, including fire-fighting systems (CO2, foam, water mist) and lifesaving appliances, is regularly inspected and maintained in a state of readiness.
  • Liaise effectively with port state control officers, classification society surveyors, and other external authorities during inspections and audits.
  • Develop and implement risk assessments and safe work procedures (e.g., lock-out/tag-out, enclosed space entry) for all engineering tasks.
  • Manage the vessel’s electrical power generation and distribution systems, including switchboards, transformers, and emergency power supplies.
  • Maintain and test automation, control, and alarm systems throughout the engine room and machinery spaces to ensure their proper function.
  • Take a leading role in emergency response situations, directing the engine room team in drills and actual incidents such as fire, flooding, or blackout.
  • Provide hands-on training, mentorship, and competency assessment for junior engineers and engine room ratings to support their professional development.
  • Oversee the condition and maintenance of the ship's HVAC and refrigeration systems, ensuring crew comfort and proper cargo conditioning where applicable.
  • Manage the vessel's water production systems (freshwater generators/reverse osmosis) to ensure a sufficient supply of potable water.

Secondary Functions

  • Participate actively in the vessel's safety committee meetings, contributing engineering-specific insights and recommendations.
  • Assist the Master in technical aspects of voyage planning, especially concerning fuel and engine performance calculations.
  • Contribute to the development and refinement of company-wide engineering policies, procedures, and best practices.
  • Support new-build or vessel conversion projects by providing operational feedback on design specifications and equipment selection.

Required Skills & Competencies

Hard Skills (Technical)

  • In-depth expertise with large marine diesel engines (e.g., Wärtsilä, MAN B&W), including performance tuning, overhauling, and troubleshooting.
  • Strong proficiency in marine electrical systems, including power generation, distribution, high-voltage (HV) systems, and motor controls.
  • Comprehensive knowledge of auxiliary systems: purifiers (Alfa Laval), air compressors, boilers, pumps, and heat exchangers.
  • Advanced skills in automation and control systems, including PLCs, pneumatic controls, and integrated machinery alarm/monitoring systems.
  • Hands-on experience with welding, machining, and fabrication techniques for onboard repairs and modifications.
  • Mastery of Planned Maintenance System (PMS) software such as AMOS, STAR IPS, or similar enterprise asset management platforms.
  • Thorough understanding and practical application of international maritime regulations (MARPOL, SOLAS, ISM, ISPS, STCW).
  • Competency in hydraulic and pneumatic system maintenance and repair, including cranes, winches, and valve actuation systems.
  • Proficiency in conducting and interpreting fuel, lube oil, and water analysis to monitor machinery health.
  • Experience in managing complex projects, such as dry-docking specifications, budget preparation, and shipyard supervision.
  • Knowledge of modern vessel efficiency technologies, including scrubbers, ballast water treatment systems (BWTS), and performance monitoring software.

Soft Skills

  • Exceptional Leadership and Team Management
  • Resilient Problem-Solving and Critical Thinking Under Pressure
  • Clear and Concise Communication (Written and Oral)
