The vessel was handed over to Vroon during a ceremony held at Cosco. The PX121 design, with 850 m2 deck space, is an X-BOW® design which ensures reduced and smoother vessel movements in harsher conditions. This provides better operational and fuel-efficiency advantages to the charterer, in combination with high crew-comfort standards. The vessels will be delivered during 2015 and 2016.
VOS Paradise delivered
On 4 August 2015, Vroon took delivery of ‘VOS Paradise’, an ULSTEIN designed platform supply vessel of the PX121 design. 'VOS Paradise' is the second of six in a series being built at Cosco Guangdong Shipyard, China.
