Explosões de cárter em motores diesel marítimos

Abstract

‘Crankcase Explosions’ is a very important subject as to the crewmembers (specially the engine room staff due to the fact that involves their personal safety) as to the owner (because of the high potential risk of damages and non-scheduled operational stops, i.e., downtime). The marine diesel engines have been modified over the years mainly due to accidents where people lost their lives. Looking to the Classification Societies statistics, international rules were implemented in order to reduce the number of incidents and also to improve the vessels safety. Roughly, these rules estate that safety devices, such as oil mist detectors and crankcase safety valves have to be installed. In spite of the gravity of this subject, most of times it can be seen onboard a negligent attitude related to this matter, either due to inexperience or, unfortunately, lack of interest of the engine room staff members.
