The Application of the Tripod Beta Approach in Assessing the Effectiveness of the Port Security Measures in Compliance to the International Ship and Port Facility Security Code

Ghim Teck Lee, Muhammad Zaly Shah


Presently the port facility measures their compliance ISPS Code requirement is via periodical internal and external audit where documentations sampling are cross reference to the measures and procedures stipulated in the Port Facility Security Plan (PFSP). Unlike the safety related processes where the availability of positive performance measurement system allows an organization to determine the effectiveness of the system implementation and identification of level of performance. The absent of such system in the security environment leave questions on the method of determination on it effectiveness level, and how the port facility would positively identified gap(s) in the implementation without having to expect for accidents or attacks on the facility to occur, to determine the level of effectiveness. This research studies the various quality and quantity assessment process for determining risk and accident investigation tools used by the industry. From the tools available, Tripod-Beta accident investigation approach is identified as the most appropriate approach to measures the effectiveness of security measures and procedures implemented by the port facility. From there the audit measurement methodology was developed and tested on port facilities that complied to the ISPS Code requirement.
