FORMAL SAFETY ASSESSMENT OF OFFSHORE 47
SUPPORT VESSELS

To remove incident, it is clearly can be seend tht the proper communication is the most effective.
It doesn't come with a great cost and implementing additional lines and/or communication chain
of command will be very effective. When the incidents checked, with proper communiction most
of them cn be eliminated. For example, even the engineer and/or officer is less experiences, with
proper communication chief engineer and/or captain can supervise that crew. In the same sense,
many things can be eliminated with this way. To remove accidents, proper watchkeeping is a lot
more effective than the others. According with the historical data, many accidents have occured
due to poor watchkeeping. It is not costly and with the proper guidance, watchkeeping can be
improved great deal. To remove consequence, emergency instructions and fire fighting training
seem better picks. Even though arranging training can cause to spend some money, it can be
effective for the ship crew to react fires on board. Emergency instructions will be very helpful
too, these procedures can be created with a very little cost, however, can be implemented through
ISM implenentations of a ship.

When the fire/explosion checked, on the first intervention, planned maintenence and improving
resting hours can be picked. Even though improving manning (through agencies and/or better HR
departments), can add great benefit. However, the cost will be greater too. The most beneficial
solution is planned maintenance implementation on board to material failure. Ships already must
have relevant spare parts and with the planned maintenance, in the long term, it will help company
to reduce costs by preventing and damage to equipments before happened due to planned
maintenance. At the second intervention, observing machinery seems the best solution. An
oberservtion can be made by duty engineers and aslo can be recorded for the further information.
This doesnt affect the general cost but this can improve the monitoring of risky equipmentes
before any failure or malfunction.

When the intervention to remove accident is checked, there are several options with the higher
score than others. Proper communication and additional fire extiungishers could be picked to
remove any fire or flme or sparks. With proper communication, many problems and observations
can be solved beforehand especially with the supervision of higher rank crew. Also, additional
fire extiungishers can be effective to deal any kind of fires/sparks before getting dangerous and
bigger. Therefore, additional extinguishers cn be put on board even though they are not mandotary
to use highher numbers. In order to remove the last stage, emergency instructions and ship specific
procedures can be very effective. In accordance with previous steps, to avoid such consequence,
ship crew must be very good at ship handling and the reaction in that specific ship.

The last step helps to make a decision and giving a recommendation for safety. In other words,
with proceeding step 5, recommendations are to be presented to keep risks minimum as much as
possible. Output of this step should give an objective comparison of alternative options based on
the potential reduction of risks and cost effectiveness in areas where legislation or rules should be
reviewed or developed and feedback information to review the results generated in previous steps
[1]. At this point, the recommendations are to be divided into two groups for
"Collision/Contact/Allision" category and for "Fire/Explosion" category.

In this paper, human error has been assessed for the collision category. When the historical datas
have been checked, it is very clear that the human factor is the most contributing effect to the this
type of hazard and therefore, it has chosen. In this regard, human error is a good choice. It can be
seen that the operational mistakes and less experience are the most important factors. Especially,
crew related this sub category must be focused through the interventions and implementations of
improvement of crew. Better training schedules and implementation will have great impact. Also,
related prohibitions, internal regulations and such through the management company will be
effective too. While doing these, communication, watchkeeping and as well as judging effects by
the crew will be increased positively. Of course, at the last stage, these improvements will be
