Thread: Cook Strait Ferry

It's much easier to drive from Picton to Christchurch in a 50 knot Southerly than try get there via sea.

The ship would roll over slowly then flick back upright - quite nasty.

as an ex grunt i could take umbrage ,but reading between the lines an ex blanket folder or corp of trucks.

B) being a marine engineer, I think I know the difference between a ship and a haul truck.... the truck will not float, hence the barge.

HAHAHA yeah well, I've seen a haul truck float - you'd be surprised how much bouyancy there is in the bloody great tub on the back. Probably be a different story with the tub loaded of course.

I've been around surveyed vessels for a long time as well, and come in after a few plans have been put together, class survey reviewed and signed off. That's about when you discover how many cockups there were in the plans. One of them had the fuel system to the auxiliary systems on that vessel completely wrong, I'm not sure how many people missed the error in the developed operational procedures and maintenance process documentation but what they had done was set the valves in the auxiliary operating procedure to run the main engine effectively off the auxiliary quarantine 'day tank' and returning the fuel from the main engine to the keel main storage tanks. Not ideal, and as I said not too sure how that many people looked at the system including developing CAD drawings of the fuel plumbing systems and still miss that. It does show that stuff can be missed and not picked up until the inevitable failure occurs.
