Thank you Denis for providing the accurate info about SWL of the heavy lift derrick on this ship ( and I also must apologize for not previously reading your below comment before post of mine previous comment) :-)

I well recall this ship being one time at shipyard Viktor Lenac, Rijeka (by end of 1970s) for drydocking & repairs ..... and at that time there, she was personally for me, an 'extremely impressive' ship in overall !

..... and Mike, I'm much sorry for not being able to help you,, I also don't know the SWL of the heavy lift mast/derrick that this ship had :-)

Not much, only 120t from this excellent GA plan - http://www.seeleute-rostock.de/content/moreships/3-Freighter-20/3d-Indik-I/maxi/slr-indik-gplan-gr.jpg

@Denis - yes a very impressive looking heavy lifter built to cater for the export demands of the heavy industry of the old DDR. I wonder what the capacity was of the Stulcken type crane?

Great!!!
