These incidents should be investigated sinc

3、e many flag administration regulations require it; international agreements mandate it (such as the IMO “International Safety Management Code”); and industry initiatives encourage it. Incident investigation is a process that is designed to help organizations learn from past performance and develop s

4、trategies to improve safety. The ABS Marine Root Cause Analysis Technique (MaRCAT) provides an effective and efficient approach for investigating marine incidents of any magnitude. ABS developed the MaRCAT methodology by customizing and combining the best techniques available and by proving and impr

5、oving the overall approach through MaRCATs application during numerous investigations. The ABS MaRCAT approach to incident investigation caters to the unique needs of the marine industry, including human element; machinery and engineering; structural and security concerns. The objectives of the ABS

6、MaRCAT approach are as follows: Provide ABS clients with a technique that will guide incident investigators in the conduct of root cause analyses and in identifying, documenting and trending the causes of accidents and near misses. Assist clients with the investigation of a variety of types (e.g., g

7、roundings, collisions, fires, etc.) and sizes of incidents (minor to major, including near misses) related to their vessels and facilities (ashore and at sea). Allow analysis of losses whether they are related to safety, the environment, human element concerns, security, reliability, quality or busi

8、ness losses. Support Class-related activities such as ABS Safety, Quality and Environment (SQE) notation, as well as the International Safety Management Code (ISM Code) and the International Ship and Port Facility Security (ISPS) Code. Provide a technique that is sufficiently flexible to allow custo

9、mization to a clients own management system, Health, Safety and Environment (HSE) programs or related initiatives. These Guidance Notes provide instructions for the performance of incident investigation activities, including: Incident Investigation Initiation Data Gathering Data Analysis Root Cause

10、Determination Generating Recommendations Reporting and Trending of Incident Investigation Results The ABS Guidance Notes on the Investigation of Marine Incidents provide a structured approach to the investigation of incidents and near-miss events. The information contained can also assist with ident

11、ifying and documenting root causes as required by the ISM Code. These Guidance Notes describe an incident investigation methodology that was expressly developed for the maritime industry, and so it reflects those elements of maritime operations and incident causation particular to the industry.
