Typical Attack Profiles and Lessons Learnt

  1 During 2008 significantly increased pirate attacks on merchant ships occurred throughout the GoA and off the coast of Somalia. The majority were clustered around the northern side of the GoA but some attacks have occurred further off the east coast of Somalia.

  2 Analysis of successful attacks indicates that the following common vulnerabilities are exploited by the pirates:

  • a. Low speed

  • b. Low freeboard

  • c. Inadequate planning and procedures

  • d. Visibly low state of alert and/or evident self protective measures

  • e. Where a slow response by the ship is evident.

  3 Commonly two or more small high speed (up to 25 knots) open boats/“skiffs” are used in attacks often approaching from the port quarter and/or stern.

  4 The use of a pirate “mother ship”, which is a larger ship carrying personnel, equipment and smaller assault craft, has enabled the attacks to be successfully undertaken at a greater range from the shore.

  5 Vigilance should be highest at first light and last light, as the majority of the attacks have taken place during these periods.

  6 To date no successful attacks have occurred on ships at 15 knots or more.

  7 The majority of attempted hijacks have been repelled by ship’s crew who have planned and trained in advance of the passage and employed passive counter measures to good effect.
