The reason for all the changes in cranes :
1st : little capacity 12.5 mto SWL / Gemini aft = 25 mto
2nd : lifting height and stowage position of jib.
It was a real pita at times to work with that ships in our trade

Thanks to all friends for the informations.
It's most likely to be the Harwich Star.

By far the most noticeable feature is the very high pair at crane 3. KRISTIN STAR does not appear ever to have had these fitted - this photo taken just months before her demolition:

Also all the photos I have found of KRISTEN STAR have funnel with blue band.

On the other hand photos of HARWICH STAR show the very high cranes, including

Looks like a recent replacement boom on crane 2.

Not much help in identification of vessel in picture but I can add the following information:-
Harwich Star 7428952 ex Ibn Duraid BU Chittagong 17/12/2000
Kristin Star 7428988 ex Ibn Khaldoon BU Chittagong 20/12/2000

I don't think the cranes match the Harwich Star 100% , Crane 1 used to be a Gemini Set , Crane 2 looks different also, Crane 3 Gemini Sei is ok, but Crane 4 went missing.
So, if it was the Harwich Star they changed / replaced lots of cranes. The original cranes on the Korea builds came from O&K

I remember of the Harwich Star here but Kristin Star not.

Looking better, Harwich Star's cranes do match the mystery, they are quite different to Kristin Star's cranes. I stand corrected :)

I think the aft. cranes of Harwich Star do not match with the aft. cranes of the MYSTERY, but the cranes of Kristin Star do.

Or maybe Kristin Star - http://www.shipspotting.com/gallery/photo.php?lid=1686760

I think "Harwich Star". The length of the name lettering seems to match, as do the hull and funnel colours
