Logbook oddly missing for bulk carrier (3)
I believe the answer is:
obo
'bulk carrier' is the definition.
(I know that OBO is a type of bulk carrier)
'logbook oddly missing' is the wordplay.
'oddly missing' indicates alternate letters (letters in odd-numbered positions removed).
The alternate letters of 'logbook' are 'OBO'.
'for' is the link.
(Other definitions for obo that I've seen before include "Vessel carrying ore" , "cargo ship" , "tanker" .)
