The NG-3500X is the latest design in GustoMSC’s series of self-propelled jack-up designs – the NG series. Based on the NG-2500X and NG-1800X designs, the NG-3500X comes in two distinct versions for accommodation, services and well intervention. The NG-3500X can operate in a water depth of up to 80m (262ft) and bridges the gap between the successful service units and the full-fledged drilling rigs for the Middle Eastern and Southeast Asian markets.
The NG-3500X is a solution for maintaining and making interventions in the large number of mature fields and infrastructure in the Middle East and Southeast Asia. The conditions of these fields are characterized by deeper water and larger expected penetrations. Until now this was the domain of classic drilling jackups and work barges.
The NG-3500X has a transit speed of up to 8 knots, an optional DP system, and comes in two distinct setups. The first set up is a multipurpose platform with various crane options for services which include simple maintenance jobs, accommodation and support to light well intervention. The large free main deck, approximately 1200sq m (12916sq ft), allows for flexible use, transporting equipment and materials to and from offshore locations, placing an additional accommodation block on it, accommodating a modular well intervention spread, etc.
The second set up is a dedicated unit for heavy well intervention and light drilling. The X-Y skidding system provides a large drilling envelope of 15.2m x 7.3m (50ft x 24ft) and additional deck space as it raises the entire cantilever and drill floor structure above the main deck by approximately 3.5m (12ft).
