Shipboard safety

  • Increase vigilance and surveillance
  • Be aware of potentially suspicious craft approaching
  • Consider additional lookouts, briefed on maintaining a clear watch astern and over the side and equipped with appropriate (night vision) binoculars
  • Ensure watertight integrity is maintained, and all fire-fighting equipment is available for immediate use


  • Comply with the navigational norms in the Strait of Hormuz, including the COLREGs Rule 10 (Traffic Separation Schemes)
  • Observe any exclusion zones issued by coastal states
  • Use inshore traffic zones only if calling at ports within the inshore area or to avoid immediate danger
  • Consider if a Day/Night transit is appropriate to the threat posed
  • Ensure watch officers save Voyage Data Recorder (VDR / SVDR) data in the event of an attack or suspicious event in the vicinity of the vessel

Members should also comply with guidance from the relevant Flag Administration and implement appropriate recommendations from BMP 5 as required.
