Jana Marine Services takes delivery of jackup trio from Chinese yard

Jana Marine Services of Saudi Arabia recently welcomed three new jackup vessels to its offshore support fleet.

Jana 505, Jana 508 and Jana 509 were built in China by CSSC Wuhan Marine Machinery Plant (WMMP). Jana 503 and Jana 504, two earlier jackups from the same series, were delivered by WMMP in 2024.

The jackups each have a displacement of 5,700 tonnes, and accommodation spaces for up to 150 personnel in the bow. The four pile legs, which each measure 95 metres long, can be extended via a 110-tonne electric rack and pinion lifting system to allow safe deployment in water depths of up to 55 metres.

Also fitted on each jackup are a helicopter deck and two pile winding cranes. Each crane has two dedicated 200kW motors and a safe working load of 100 tonnes.

A total deck area of 1,400 square metres will meanwhile help facilitate oilfield services or accommodate payloads totalling over 4,800 tonnes.
