Stefano Beltrando to scrutinize VOR fleet with ultrasound tech
Every Volvo Open 70, except Groupama 4, is being scrutinised with ultrasound technology by the founding owner of Q.I Composites Stefano Beltrando, who pioneered the application of the science in the marine field 12 years ago. Groupama have their own in-house ultrasound solution.
Beltrando and a colleague are spending about two days per yacht checking the main problem areas including the hull, bow, keel, dagger boards, rudder and mast.
The pulse echo can detect defects as small as a two-centimetre delamination, which could prove race-ending during the 39,000 nautical mile offshore challenge.
‘The point of this race is being able to take the boat to the last leg,’’ he said. ‘To win a race you have to be able to sail as fast as you can without any failures, so to find the small defects and fix them so you can avoid really big disasters is critical to winning.’
Beltrando said that during the 2008-09 race, when he worked with teams including the winners Ericsson 4, defects were found on every boat at every stopover. He said that the constant push for the boats to become lighter and faster meant there was no extra protection.
‘On these boats, they are very light so there isn’t extra material, so the challenge is to find the small defects before they become a big problem.’’
Like most, Beltrando reckons that the line-up of the 2011-12 is more competitive than ever before. It is an opinion he has formed having worked intimately with the second generation yachts in 2008-09 and with teams including Team Telefónica, Puma Ocean Racing powered by Berg and Camper with Emirates Team New Zealand since their construction began for this edition.
Beltrando said there were some obvious changes and advancements in design and composition of the new-age fleet.
‘The main difference is that in this generation the quality of the building is very high and it has levelled out between the teams,’’ he said.
‘Last time Ericsson 3 and Ericsson 4 were at a higher level of construction. This time they’re all really nice boats.
‘They’ve used the best skilled guys in building, more of the same materials and more of the same processes. Compared to last time, this time is much better. That doesn’t mean they’re stronger, but if you have a perfectly built boat already, psychologically it’s a good thing for the crew.’
Beltrando and his colleague were spending Thursday finishing their examinations of Telefónica and Abu Dhabi Ocean Racing’s Azzam. By mid-afternoon in China the two were starting work on Camper and Sanya.
Groupama’s ultrasound work is done by Eric Beylot, a member of the shore team and a boat builder by trade. Team technical manager Ben Wright commented. ‘The great thing about having a member of our team who can do the ultrasound is the continuity. He knows us, he knows the boat and those factors combined create a very good outcome.’
The ultrasound is part of several major operations that shore crews are completing this week before their yachts are returned to the waters of Sanya Bay early next week.
The DHL Shore Crew award for Leg 3 will be announced next week.
