Engine Room Daily Inspection Checklist [FREE PDF]

Daily engine room inspections are a core requirement of the ISM Code (IMO Resolution A.741(18)) and USCG 46 CFR Part 62, ensuring that propulsion, auxiliary machinery, and environmental systems remain operational and compliant. MARPOL Annex I mandates strict monitoring of oily water systems and bilge management to prevent marine pollution. Marine engineers must document all readings and deficiencies in the Engine Log Book as required by SOLAS Chapter II-1 and port state control inspection regime

Industry: Maritime
Frequency: Daily
Estimated Time: 45-60 minutes
Role: Marine Engineer
Total Items: 36
Compliance: ISM Code IMO Resolution A.741(18) Section 10 – Maintenance, MARPOL Annex I Regulation 14 – Control of Discharge of Oil, USCG 46 CFR Part 62 – Vital System Automation, SOLAS Chapter II-1 Part E – Electrical Installations, OSHA Maritime 29 CFR 1915.163 – Internal Combustion Engines

Main Engine

Record main engine operating parameters and inspect for defects, leaks, and abnormal conditions.

Is the main engine running within normal RPM and load parameters?
What is the main engine jacket cooling water temperature (°C)?
What is the main engine lube oil pressure (bar)?
Are main engine fuel injection systems free of visible leaks?
Are exhaust temperatures within normal range for all cylinders?
Are main engine alarms and safety trips tested and operational?

Auxiliary Machinery

Inspect generators, compressors, pumps, and auxiliary systems for proper operation.

Are all running generators within normal voltage and frequency output?
Is the emergency generator tested and ready for immediate start?
Are air compressors maintaining required starting air pressure (bar)?
Are all auxiliary pumps (fire, bilge, ballast) operational and ready for use?
Is the freshwater generator/evaporator operating normally (if in use)?

Fuel Oil Systems

Inspect fuel storage, transfer, purification, and consumption monitoring systems.

Are fuel oil tank levels recorded and consumption within expected parameters?
Is the fuel oil purifier operating at correct bowl speed and temperature?
Are fuel oil heaters maintaining correct viscosity for injection (cSt)?
Are all fuel oil tank vents and overflow systems clear and unobstructed?
Is the fuel sulfur content log updated with current bunker sample data?

Bilge and Oily Water Systems

Monitor bilge accumulation, oily water separator operation, and ensure MARPOL compliance.

Are bilge well levels measured and recorded in all spaces?
Is the oily water separator (OWS) 15 ppm alarm system tested and operational?
Are all bilge pump suctions free of blockage and tested?
Are Oil Record Book (ORB) Part I entries completed for all bilge operations?
Is there visible evidence of oil contamination in bilge or machinery spaces?

Cooling Water Systems

Inspect sea water, fresh water, and central cooling systems for adequate flow and temperature control.

Is the central cooling fresh water temperature within normal operating range (°C)?
Is the sea water inlet strainer cleaned and free of blockage?
Is the cooling water treatment chemical level within the manufacturer's specification?
Are all cooling water heat exchangers free of visible leaks and corrosion?
Is the charge air cooler (turbocharger) inlet temperature within normal limits?

Electrical Systems

Inspect switchboards, insulation resistance, and electrical safety in the engine room.

Is the main switchboard free of overloaded circuits and alarm conditions?
Is the earth fault monitoring system showing insulation resistance within limits?
Are battery banks (UPS, emergency, starting) fully charged and tested?
Are all electrical panels in engine room free of moisture, corrosion, and damage?

Engine Room Safety and Environment

Verify engine room safety equipment, ventilation, and personnel protection compliance.

Is the engine room ventilation system operational and providing adequate air supply?
Are all required personal protective equipment (PPE) items available in the engine room?
Is the engine room fixed CO2 smothering system pressure and weight within limits?
Are all engine room escape routes and emergency exits clear of obstruction?
Has the engine room log been completed with all readings and deficiencies noted?
Are there any outstanding deficiencies or defects from previous watch to report?
