Qualification of the Deepwater Subsea Well Intervention System 'AX-S' for 10,000 ft Operations

摘要

This paper presents a detailed description of the technology qualification for the novel deepwater subsea well intervention equipment, the “AX-S? system” developed by Expro AX-S Technology Ltd, and how the statement of feasibility of the project was developed and successfully achieved. Using the framework for technology qualification - Det Norske Veritas’ recommended practice “RP-A203: Qualification Procedures for New Technology”, DNV and Expro AX-S overcame a series of challenges to deliver the first project milestone (statement of feasibility) while ensuring that the project timeframe was not impeded. The Expro AX-S subsea well intervention system can operate in depths of up to 10,000 feet and negates the need for a drilling rig and riser systems, instead using remote intervention from a dedicated monohull vessel.
