I worked there myself. The vessel is realy nice. The vessel crew was not your typical construction vessel crew but they were making progress. The ROV is limited, beyond what it was designed for, rebuilt one too many times, basic centurion junk. And yes, it has a TMS. The ROV crew was ready, willing, and able but limited by equipment. As far as the client rep., it depends on which one you are referring to?
TAXES, big reason for not going back myself. But that can be resolved upfront as long as you know about it. Get all the details before you agree to go. And make sure they(SS7) supply you with malaria pills, Hess doesn’t supply them but expects us to take them. One other thing, E.G. has changed a few requirements for entry. You now have to have a police back ground check before they will issue you a visa.
