I had an occasion where I was contacted by the operations manager for a shipping company who saw a image of one of thier owned and operates ships on this site taken by me, he first questioned wether the name of the ship was correct, pointing out to me that the ships orders were to sail from Newcastle, Australia and was meant to be going to Port Pirie in South Australia to discharge and then sail for Indonesia, but instead the ship was at Risdon near Hobart. He was toataly confused, pointing out to me the ships orders had nothing about coming to Tassie. Secondly he asked if he could use the picture that he spoted of mine on this website of mine on their webpage. I said yes.
He never did find out why the ship had been sent to Risdon and who changed the orders as they all had to go through his office!
So some of the shipping companies from my experience use this site as a resource.
