RIDING MILL, U.K. — Osbit has delivered a new well intervention tower system to FTAI Ocean.
The 40-m tall system, comprising 1,300 metric tons of equipment, will enable riser-based and riserless well interventions in water depths up to 1,500 m.
Osbit adapted the tower’s vertical racking system to reduce the need for well center access, with a further focus on maximizing deck space (due to the relatively small footprint). An active and passive heave-compensated platform supports coil tubing, slickline and e-line operations, with personnel access via an integrated walk-to-work system.
For riserless operations, the system provides four guide wires and two pod wires. These are integrated with the existing vessel crane, which offers up to 250-metric ton safe working load active heave compensation.
The system’s deck skidding system is said to minimize the need for crane lifts, widening the operating window and allowing equipment to be directly loaded into the well center.
Wilton Engineering Services in Teesside, northeast England, fabricated and assembled the tower, supported by Osbit’s mainly local supply chain.
