Fast Crew Supplier 2710 "HST Sofia" UK-based crew transfer specialist High Speed Transfers (HST) took delivery of the second Damen Fast Crew Supplier (FCS) 2710, the HST Sofia. The strength of the design is demonstrated by the fact that the HST Sofia is essentially identical to the HST Hudson, with just a few minor adjustments to the internal layout. HST has announced that its second vessel of Damen’s new FCS 2710 class will be contracted by Shell to support its exploration drilling programme in the Black Sea, in the Khan Kubrat block, around 70 miles south-east of the Bulgarian port of Varna.
