Stocks that Float: TANKERS & DRY BULK SHIPPERS

[xanadu90]

Deep Sea Supply concentrates on serving both deep sea and shallow offshore rigs and drilling platforms. As far as I know all their vessels are too big to handle ships in harbours.

There are of course other companies operating in offshore services - e.g. Bourbon and Norwegian Havila, I don't know them all, but DESSC is a "new generation" offshore server, and no doubt a very active and aggressive one.
