Vroon Offshore Services has enlarged its global reach with a deal in Saudi Arabia for three anchor-handling tug supply (AHTS) vessels.

It said the Saudi National Center for Environmental Compliance (NCEC) has fixed the trio on a "multi-year" contract for oil pollution response work in the Red Sea.

The 5,150-hp VOS Athos and VOS Thalassa (both built 2012) and the 5,221-hp VOS Hestia (built 2009) recently started operations there.
