Give another rating to engineers on ship in high seas
I believe the answer is:
reassess
'give another rating to engineers' is the definition.
I can't tell whether this defines the answer.
'on ship in high seas' is the wordplay.
'on' becomes 're' ('on' can be mean 'with reference to').
'ship' becomes 'SS' (prefix in ship names eg SS Great Britain).
'in' is an insertion indicator.
'high' indicates an anagram (can mean drunk or on drugs and hence disordered).
'seas' anagrammed gives 'aess'.
'ss' inserted inside 'aess' is 'assess'.
're'+'assess'='REASSESS'
Can you help me to learn more?
(Other definitions for reassess that I've seen before include "Form new opinion" , "Make a further judgement" , "Re-evaluate" , "think again" , "Test again" .)
