The second version of the SQUID generating unit was designed and built through the second half of 2012 and early 2013. The first of 3 SQUID units for testing were completed in November 2013 and shipped by road from Albatern’s workshop in Roslin to Kishorn Port for still water testing prior to open water deployment.
The extreme weather experienced in December 2013 and through to early February 2014 made conditions challenging, however, the dry dock at Kishorn provided an environment where testing could continue despite the weather making operations off the shore practically impossible.
Initial tests focused on lift and weight testing, with the first launch of the unit in early December 2013. By 20 December, the first deployment into operating mode was completed in challenging weather with short daylight hours and tidal restrictions.
In late February 2014 the second SQUID was shipped to Kishorn and the methods for coupling the units was practiced and refined in advance of having to use these processes in an offshore environment.
The 3 SQUIDs were then recovered in early April and cleaned prior to deployment in the Isle of Muck project.
