they gota website Seb which will tell you the exhibitors, You wont find any body flogging a Medline or an Adventurer there. But the normal commercial manufacturers are normally represented Avon, Delta, Halmatic. Ocean Dynamics
The exhibition covers a lot of the work aspects so you'll have crane manufacturers and Hawser companies, coupling and transmission companies,
It is open to the public and I got some free tickets from mermaid once!
I notice that Ocean Safety are exhibiting (they are next door to us in Saxon Wharf) I'll nip over an see if I can scrounge you a couple of tickets
