SPS recently completed the order with Bibby Offshore for the Cygnus Field.
70no. Wedged Concrete fleximats, with attached Artifical Fronds were supplied from the SPS Great Yarmouth manufacturing facility. The use of Artifical fronds allows for sediment to be built up over time, and protect & stabilise the Cygnus subsea assests.
To save on mobilisation time the use of concrete mattress Speedloaders were applied, this allowed for reduced vessel lifts, and port times. See more information on SPS Speedloaders here.
The Cygnus project sanctioned in August 2012 is expected to contrubute 5% of the UK gas production at its peak in 2016, the equivilant to powering 1.5 million UK homes.
