[QUOTE=tugsailor;189031]As I understand it, the AIVIQ/KULLUK tow in Alaska used a well know rig moving surveyor from the Gulf of Mexico. I do not know anything, and certainly didn’t say anything, about the surveyor for Winner.
Most of the tow surveyors I have seen came from Seattle. And most did a good job. Tow surveyors seem a lot less common now than they did years ago. Obviously, something has changed with the insurance for general coastwise towing that makes them less necessary.
A couple of times some years ago I saw Brits from the Salvage Association in Alaska. I was not overly impressed with the towing knowledge displayed by the British former master of a cable laying ship. Those guys were a complete waste of time and money.[/QUOTE]
Likewise, I also don’t know anything specific about how the Towage Approval for the two aforementioned towing operations were obtained, or who issued it.
My comment in Post # 20 about what likely went into the inspection before the CoA for sail away was issued, was purely based on how I conduct such survey, which I have done on and off for 40 years.
The requirement for Warranty Survey is largely up to the Underwriters, who also approve the company who appoint the Surveyor, by not necessarily the Surveyor.
In the Offshore Industry it is now more or less obligatory to appoint a Warranty Surveyor for every Towage and other Marine Operation, but for other type of towing, like regular cargo barges with commercial cargo and on regular run, it is less likely to be required.
The last Towage Approval I issued was for a small tug under Palau flag, but with all Ukrainian crew, towing a new Self-propelled but unmanned Hopper barge from the building yard in China to Dubai.
During the voyage they hit heavy weather in the South China Sea and the towline pulled out from the socket. They connected on the trailing emergency tow line and pulled in to the nearest shelter, where they connected the secondary towline and continued the tow to Singapore for repairs.
No drama and no news headlines, just one of the things that happen in the towing business.
If they had managed to re-connect to the T/O Winner, that would have been a non-event as well.
