Fixed object found in sea (6)

I believe the answer is:

mended

'fixed' is the definition.
('mend' can be a synonym of 'fix')

'object found in sea' is the wordplay.
'object' becomes 'end' (both can mean a goal or purpose).
'found in' is an insertion indicator.
'sea' becomes 'med' (short for Mediterranean).
'end' going inside 'med' is 'MENDED'.

(Another definition for mended that I've seen is " Repaired, fixed".)

I've seen this clue in The Daily Express.
