Inspect, maintain and overhaul fuel systems and fuel polishing equipment including filtration systems, transfer pumps, Day tanks and consumable change-outs to prevent contamination and ensure engine reliability.
Lead and conduct engine room rounds, watchkeeping and system performance monitoring, including vibration analysis, thermography and oil analysis, and record findings and corrective actions in technical logs.
Supervise and carry out refit, repair and upgrade projects from scoping and technical specification through to commissioning and testing, coordinating with shipyards, contractors and classification societies.
Ensure compliance with international and flag-state maritime regulations (STCW, SOLAS where applicable, MARPOL, flag-specific survey requirements) and prepare technical documentation for inspections, audits and port state control.
Maintain complete maintenance records, service manuals, parts inventories, technical drawings and logbooks using CMMS or established filing systems to support traceability, warranty claims and owner reporting.
Procure, manage and optimize spare parts inventory and consumables including budgeting, supplier negotiation, parts traceability, and consistency with minimum spares lists to prevent critical shortages.
Supervise, train and mentor junior engineers, electricians and engine-room crew in safe work practices, standard operating procedures, emergency response and technical competencies to build a high-performing team.
Implement and enforce onboard safety protocols and environmental best practices, conduct risk assessments for engineering tasks, and lead emergency drills (fire, flooding, spill response) with engineering involvement.
Perform routine and annual statutory checks, prepare defect lists, and manage rectification plans to ensure successful class/flag inspections and certification renewals.
Maintain and troubleshoot onboard electrical distribution systems (AC and DC), including shore power integration, inverters, batteries, chargers, switchgear and automatic transfer switches for reliable power management.
Troubleshoot and maintain navigation and communication electronics in coordination with the bridge and electronics specialists, ensuring redundant systems and critical alarms are functioning.
Lead condition monitoring and performance optimization projects (fuel efficiency, emission control, energy management) that reduce operating costs and support owner sustainability goals.
Oversee small fabrication, piping, and welding repairs in the engine room and technical spaces, ensuring high-quality workmanship and compliance with marine standards.
Coordinate with owners, captains and project stakeholders to present technical options, cost estimates and timelines for repairs, refits and upgrades, communicating risks and impacts clearly and proactively.
Participate in outage and dry-dock planning and execution, including scope definition, contractor evaluation, onsite coordination, quality control and returned-to-service testing.
Maintain cybersecurity awareness for networked engine room systems and follow best practices to reduce risk from remote access, diagnostic tools and supplier connections.
Respond to technical emergencies 24/7, taking decisive action to stabilize systems, protect life and vessel, and coordinate with onshore technical support and service providers when necessary.

Secondary Functions

Prepare and deliver technical briefings and handovers for owner/operators and relief engineers to ensure continuity between watch rotations and charters.
Support crewing and training plans by identifying skill gaps, proposing training schedules, and facilitating external courses or manufacturer-certified training.
Assist the captain and management with budgeting and long-term maintenance planning, providing input on CAPEX for refits, major overhauls and equipment replacements.
Liaise with marine warranty surveyors, classification society surveyors and insurance representatives during surveys, claims or incident investigations and provide technical evidence/documentation.
Develop and maintain vendor relationships and service agreements for scheduled servicing, warranty repairs and specialized contractor work to secure competitive pricing and quality delivery.
Conduct on-board environmental reporting, manage bilge and waste handling best practices, and support compliance with MARPOL and local port regulations.
Support guest-facing teams by minimizing technical disruptions during charters, responding promptly to owner/guest requests regarding technical systems, and safeguarding guest areas during engineering activity.
Contribute to continuous improvement initiatives by reporting recurring failures, proposing design upgrades, and documenting lessons learned following significant repairs or incidents.
