Just my uneducated opinion.
I can assure you the Orgeron boat was a fully ABS classed ocean tug boat. But she is not a tug/supply. Straight towing only. Should have been capable of handling the seas that day but for the engine room fire.
Tug/supply boats were built for oilfield use are characterized by long open aft decks so that once a drilling rig has been towed to its drilling location and anchored in, the support tug can function as a supply vessel to the rig, bringing fuel and drilling fluids in tanks below decks and pallets of supplies or stacks of pipe on deck. The long aft deck also functions as a work deck to attach long lengths of chain to rig anchors during the rig moving process.
The Bourbon Rhode should have been easily capable of handling 20í seas and works in much wilder conditions off Alaska, North Sea and Southern Ocean locations.
Letís hear what the surviving crew has to say before speculating.
