Pilgrim Eliminates Bolts From the Blue

Removing the tail shafting from Caledonian MacBraynes Isle of Lewis ferry, which runs from Ullapool to Stornaway, is a regular operation at overhaul and for survey. Recognising that the time consuming task would be necessary a number of times over the ships remaining 20 to 25 year operational life, the owners wanted a solution installed that would overcome the unpredictable characteristics of conventional coupling bolts.
