Try to get intouch,with harbours around the world,by example antwerp.Try www.portofantwerp.be
maybe that can help
for real technical issue,i cant realy help you out,and i dont think port autority's allow info on specific things.
Remember 9/11,since that all the harbour area's are now close for public.
So to find some info,will be a hard job,for you

Marc
