High safety at sea starts with good ship structural design, good arrangements to ensure watertightness, easy to use procedures, equipment and means to operate the ship and to evacuate crew and passengers in an accident to minimize effects of human errors. Safety at sea is then a human question - to keep up the good arrangements and to follow the procedures. The cost of high technical safety is small - it is just to get the arrangements right from the beginning, e.g. the Coulombi Egg tanker. Right arrangements then simplifies for the ship's crew to maintain high safety. Heiwa Co. has a lot of experience in these important fields of ship design and operation incl.
Different ships are subject to different risks.
Fishing vessels seem to be subject to the highest risks at sea - external weathertight doors may be open when fishing in severe weathers and may lead to flooding the inside spaces and sinking. Fishing vessels should therefore have extra, internal, weathertight doors to ensure sufficient bouyancy in the superstructure and deck house to survive. Safety is also all new facts about past accidents that surface long after the accident, which many administrations tend to neglect. Thus Heiwa Co. investigates all new facts about past accidents to learn from them. You can never learn too little from an old accident, thus the Titanic accident 1912 is still of interest.
