TYNESIDE, UK -- IHC Engineering Business (EB) has designed and built two next-generation deepwater pipeline ploughs. The ploughs have left EB's Hadrian Riverside workshops on Tyneside, UK en route for extensive offshore commissioning and installation on the owner's vessels.
The newbuild PL3 and BPL3 ploughs are the largest subsea ploughs EB has developed. Designed to handle pipeline diameters of up to 1.55 m (5 ft), in water depths of
1,000 m (3,281 ft), the vessels will be used for the burial of main pipeline trunk.
The new PL3 plough weighs 200 tons (181 metric tons), is 22-m (72-ft) long, has 100 tons (91 metric tons) capacity pipe handling equipment front and back, and can create a 2.5-m (8-ft) deep trench after mulitpass, and a 2.3-m (7.5-ft) maximum single pass trench. The control system will be built into the ship bridge module.
