 Proper communication,

4. Intervention to remove consequence;
 Emergency response drills,
 Emergency instructions,
 Notification to chief engineer/master,
 Abandon ship training,
 Additional fire fighting system (sprinkler etc.)
 Notification to port authorities,
 Implementation of ship specific emergency procedures.

Now, it is time to proceed step 4 cost benefit assessment. Hereby in Table 6, basic calculation for

cost benefit assumption has been shared. This step aims to understand and also compare the

benefits from reduced risks and cost of implementation of RCO as defined in step 3. Following

tables have been created in order to calculate cost - benefit assessment. At first, benefit has been

assumed based on expert opinion, historical data and maintained applications on-board. After this,

a cost has been identified in order to create intervention. Followingly, overall score can be

calculated. In Table 7 and Table 8 cost benefit analysis results have been published. It is

needlessly to say that an orderly fashion is to be created to understand the best intervention in

regard to cost/benefit assessment.
