  • Checks that call-out coverage extends throughout the accommodation, not just the duty cabin
  • Verifies records of periodic testing of the call-out/dead-man alarm system are maintained, not just a one-time commissioning test
  • Chief Engineer2nd Engineer3rd Engineer
    What the Inspector Expects
  • Establishes the Chief Engineer issues standing orders covering routine watchkeeping duties and night orders for specific operational conditions, consistent with ISM Code 7 shipboard operating procedures
  • Confirms every watchkeeping engineer, including reliefs and cadets under supervision, signs to confirm they have read and understood the orders
  • Checks that the orders are updated to reflect current voyage conditions, not a static document from months earlier
  • Verifies content addresses vessel-specific risks such as heavy weather, bunkering, or restricted-waters machinery readiness

  • Checks that test results are recorded and trended, with follow-up action when a test fails or is overdue
  • Verifies the list is vessel-specific and has been reviewed since the last dry-dock or major machinery change
  • Chief Engineer2nd EngineerMaster
    What the Inspector Expects
  • Establishes a systematic alarm testing regime exists covering pressure, temperature, level, and fire/gas alarm points feeding the central alarm system
  • Confirms tests are proactive, deliberately simulating the trip condition, rather than passive reliance on a natural occurrence
  • Checks that testing frequency matches the SMS/class requirement and covers both local and remote bridge-repeated alarm indication
  • Verifies faults found during testing are logged and closed out, not just noted

  • Chief Engineer2nd EngineerETO
    What the Inspector Expects
  • Confirms remote stops for machinery space ventilation fans, fuel pumps, and other essential services required by SOLAS II-2 are operable from a position outside the space they serve

    What the Inspector Expects
  • Confirms each machinery space bilge well high-level alarm is periodically tested by actually raising the float or simulating the level, not just visually inspected

  • Chief Engineer2nd Engineer3rd Engineer
    What the Inspector Expects
  • Confirms surfaces that could exceed the ignition-risk threshold identified under SOLAS II-2 are properly insulated or shielded so they cannot ignite leaking oil
  • Establishes a periodic inspection regime, ideally including thermographic infrared survey, to detect insulation damaged by oil soaking, vibration, or removal during maintenance

  • Chief Engineer2nd Engineer3rd Engineer
    What the Inspector Expects
  • Confirms flammable-liquid pipe connections located near or above hot surfaces are fitted with spray shields, screening, or jacketing as required by SOLAS II-2 to stop a leak becoming an atomized spray fire
  • Establishes crew know which specific joints require this protection and can identify them during a walkaround
  • Checks that shields/jackets removed during maintenance are always reinstated, and that none are missing, displaced, or damaged
  • Verifies any pipe or hose replaced during running repairs uses the correct rated material and retains the anti-spray protection
  • Chief Engineer2nd Engineer3rd Engineer

  • Establishes a formal leak register exists recording every identified leak, its location, interim control, and planned permanent repair date, demonstrating a proactive leak-management culture

  • Chief Engineer2nd Engineer3rd Engineer
    What the Inspector Expects
  • Establishes overall engine room cleanliness as a first-line fire-prevention measure, since accumulated oil on tank tops or lagging is one of the most common fuel sources for engine room fires
  • Confirms save-alls and drip trays beneath machinery prone to dripping are routinely emptied, kept free of oil buildup, and fitted with drain plugs to stop overflow reaching the bilge or a hot surface
  • Checks that cleanliness reflects genuine day-to-day practice rather than a one-time clean-up before a known inspection

    What the Inspector Expects
  • Confirms crew operating the incinerator understand correct start-up, monitoring, and shutdown sequence, including flame failure device function

  • Chief Engineer2nd Engineer3rd Engineer
    What the Inspector Expects
  • Confirms the vessel maintains the standby generator redundancy configuration required by its SMS/class notation, with a standby set genuinely ready for auto-start rather than isolated for maintenance

  • Chief Engineer2nd Engineer3rd Engineer
    What the Inspector Expects
  • Confirms crankcases, scavenge spaces, cofferdams, and similar confined machinery-adjacent spaces are treated as enclosed spaces requiring atmosphere testing and a permit before entry, consistent with SOLAS enclosed space entry requirements and industry guidance

    What the Inspector Expects
