Some very excellent analysis in this podcast. The only weak point was the attribution of the Coast Guard’s reluctance to accept Aiviq solely to institutional intransigence. The Coast Guard has some experience with Aiviq, having investigated its pivotal role in the grounding of the drill rig Kuluk in 2012. That accident resulted directly in Shell’s termination of Arctic work offshore Alaska and consequently, delegation of Aiviq to the status of ship without a contract and the motivation of its owners to unload it. That has now occurred, at the tail end of some very significant and targeted political contributions. I went to sea commercially under the US flag for over 40 years, 31 of that in command, some of that in the ice. The Master of the Aiviq at the time of the Kuluk tow was a colleague of mine. Since he’d been placed in command of the vessel he’d reported the unsuitability of the ship for the high latitude conditions it was built for and offered mitigations. The deficiencies included trim and stability issues, the fuel system, and retention of hundreds of tons of seawater on the aft deck during even moderately heavy weather. The Coast Guard knows this as well. Over the course of my career I was a plank owner on several vessels and spent most of my time on ships younger than 10 years of age. At least part of the problem with shipbuilding in the US is that the modern design process seems to take into consideration customer requirements for overall capabilities, capacities, and work space desires first, then fit that into an often high-windage, ungainly and slab-sides platform that will meet regulatory requirements. Those regulatory requirements generally preclude structural failure if scantlings and loading guidance are maintained and certainly address intact and damage stability. What they don’t do in a systematic way is address the sea-kindliness of the ship, or even it’s real seaworthiness. There’s more to it than adequate metacentric height. Aiviq suffered from this as much or more than most of her contemporaries coming out of commercial yards. An anecdote may illustrate the broad problem more succinctly: I once took delivery of a new vessel and, standing at the aft control station with the shipyard representative, asked why there were no wipers on the windows directly in front of the controls. I was told the inboard angle would keep the rain off, and spray would never get that high.
