In many studies involving historical and climatological subjects, it is
known that deck log records are used as a major source. The deck
log books have also appeared as one of the key sources of marine
accident investigations. Recently, many international conventions
impose obligations for different types of records. It is seen that
record requirements do not come from a single written source.
As a result, different applications and deficiencies arise. Keeping
incomplete records is reflected as a deficiency in PSC inspection
reports, and even in some cases, it leads to the detention of
ships. The aim of this study is to collect the deck-log recording
requirements from different sources, classify them under main
titles and compare their distribution by a quantitative approach.
Recording requirements were obtained from SOLAS, MARPOL,
ILO, MLC, COLREG, P&I, and Flag states, a total of 135 record
examples were collected for different stages of ship operation.
One unanticipated finding was that SOLAS Chapter 5 and ICS
Bridge Procedures Guide are not a sufficient guide for up-to-date
deck log recording requirements. The study provides a systematic
analysis of recording standards, unlike previous studies that use
deck recordings only as data sources.
