Together in Safety • Incident Prevention • Engine Room Flooding

Engine Room Flooding

Risk of serious injury and sinking due to failure of seawater circulation systems or structural failure.

Sea water pipe leakages, overboard valves not holding and seawater filters not boxed up correctly are the top causes of engine room flooding.

Container Fires
Engine Room Fires
Heavy Weather
Navigation incidents
Bunker spills
Container Losses
Lifting Operations
Mooring Operations
Personnel Transfer

Guiding Principles

  1. The main categories for engine room flooding can be categorized within the following groups: Grounding, collision, failure of internal systems breaching hull integrity, Seawater systems, Oily water separator, Sewage system overboard, Boiler water blown down, Exhaust gas cleaning systems, Fire pump / emergency systems, Stern tube seal integrity failure, Ballast water, systems, ODME, Seawater tank
  2. Conduct daily, weekly, monthly, annual, and 5-year maintenance and inspection routines in accordance with manufacturer’s instructions and company Planned Maintenance cycles, paying particular attention to the integrity of the material condition of piping systems, structure and shipside connections.
  3. Test bilge alarms, emergency pumps and associated piping / valves (especially emergency bilge suction valve) in line with the onboard Planned Maintenance schedules.
  4. Inspect all hull penetrations, shipside valves, Stub pieces, Sea chest and gratings, and complete overhaul and thickness measurement during maintenance, drydock and special survey renewals. Shipside valves are to be renewed only by Class certified valves.
  5. Ensure that any work being completed by contractors to external hull fittings / hull structures / underwater diving operations is compliant with regulatory requirements and supervised by a Company Superintendent or Senior Officer. Communications must be always maintained between contractors and appointed responsible person onboard.
  6. Complete a risk assessment is completed before commencement of any work and implement robust isolation control. Permits to work for Pipelines, and underwater operations to be used.
  7. Run flooding / damage control drills onboard. Train crew in Engine room flooding and damage control responsibilities. (The time limits set out in SOLAS for ship abandonment should be considered as a secondary objective when conducting flooding drills and must be considered as part of a flooding scenario.) Drills must be conducted safely and regularly.
  8. Rotate crew to different tasks during drill exercises. All crew must be able to demonstrate the location of isolating devices and the operation of pumping arrangements in the event of an emergency.
    SQE Marine Checklist: Flooding
  9. Hold a debrief after each drill and reflect on what went well, and what needs improvement.
    Risk Focus: Catastrophic Machinery Failure
  10. Conduct Sailing Engineering audits to inspect and verify hull integrity / penetrations whilst vessel is within its normal operational environment.
  11. Hold an engine room flooding drill and verify crew competence during one of the annual inspections onboard by the Technical Superintendent. Verify crew readiness, familiarity of emergency systems and safe working practices.
  12. Interview crew on their understanding of emergency systems / piping and contingency measures.
  13. Track and trend system and hull connection condition.

      Human performance & wellbeing

       

      Research shows that safe and well-motivated teams are happier and more productive – and we all have a role to play in making sure incidents are reduced and everyone feels that they are being looked after at work.

      The Maritime wellbeing website below has a wealth of information on how leaders and individual team members can take steps to improve physical and mental wellbeing.

      Golden safety rules

      The 9 Golden Safety Rules focus on the work areas known to have a significant impact on safety in the maritime industry – from fall prevention and spotting hazards to hotwork and navigation.

      Taking each area in turn, the rules highlight the key issues involved and give operators a series of Dos and Don’ts that can be shared with employees to promote safer working practices.
