Response: -From Martin Landtman, Senior Vice President, Marine Operations: In response to our own review of the Liberty fire incident, the company implemented a multistage process to address improved training and familiarity with the water mist "Hi-Fog" systems in use on our ships. This response effort also addresses the above recommendation from NTSB. In summary, the stages were as follows: • The first stage was to implement a series of fleet-wide communications relevant to instructions on how to operate the system. This was done within the weeks following the Liberty fire and new signage with easy to understand instructions was created and tailored by class/ship as appropriate for posting at all the system control locations. Relevant training was conducted. • The second stage is continuous and on-going involving training conducted on board by Marioff (equipment manufacturer) representatives after every annual inspection. • The third stage is a comprehensive training and certification program for both operation and maintenance personnel developed in conjunction with Marioff. It extends beyond the engine machinery spaces to also include accommodation and galley locations. The training program is comprehensive including theory, hands-on training and a final written test. The training will be carried out by a Marioff certified trainer on board each ship twice per year and certification valid for three years. Roll out of this training program to the fleet is expected in Q4 2017.
