Log books are an important part of daily routines that are carried out onboard ships for they help to keep together all the records of what is happening inside the ship. An engine room log book is a track record of all ship machinery parameters, performance, maintenance, and malfunctions.
The recorded values and information are used as a reference, to compare and record data that can be used for insurance claim if some accidents take place.
A responsible marine engineer watch keeper has to fill the log book for his/her own watch period without fail, along with the signature of all watch keepers for their concerned watch timings. Chief engineer also must counter sign this book every day to make sure all the entries are being filled in it as per the company requirement.
