A MAJOR marine operation is to be carried out in the River Forth this weekend.
Allseas’ Pioneering Spirit, the largest construction vessel in the world, is scheduled to transfer its cargo of a topside drilling platform to the 200-metre long cargo barge, Iron Lady, on Saturday evening.
The Pioneering Spirit is 382 metres long and 124 metres wide and was specifically designed for the single-lift installation and removal of large offshore platforms. The vessel has a lift capacity of 48,000 tonnes.
The following morning, the Iron Lady and its cargo will disengage from the Pioneering Spirit and will be towed by Forth Ports’ tugs, the Craigleith, Inchcolm and Fidra, under all three Forth crossings to the Port of Rosyth.
