Most frequent questions and answers
The CAN by Neodrill (suction anchor) is expected to fit about 80% of the NCS well location geotechnical conditions. As such, geotechnical data collection and detailed foundation design should be carried out early to confirm geotechnical feasibility
To conduct the detailed foundation design, NST typically require geotechnical data and applicable loads from well construction.
The IDS input sheet may be submitted to NST to start the detailed foundation design process.
The IDS may be delivered in 4-12 months lead time, dependent on IDS rental pool availability, SPS supplier selection and general manufacturing time. Early commitment is recommended to secure availability.
NST will be the system integrator and Neodrill will deliver the CAN. A complete overview of 3rd party suppliers and services will be prepared for each application.
Qualification of a new SPS suppliers HPWHH will typically add 2-3 months lead time to regular manufacturing lead time, and require a commitment from operator.
The fatigue life of the IDS is more than 500 days at worst case conditions, and will be evaluated for each application as part of the detailed design process. Contact NST for more information.
The IDS fatigue life is superior to conventional well foundations. Analysis has been conducted and results confirmed both for the IDS itself and for the H4 profile of the SPS supplied HPWHH. Contact NST for more information.
The IDS is designed for the maximum loads from Norsok with a significant safety factor. The vertical load capacity is significant and will be optimized for each application as part of the detailed design for each location.
The strength of the IDS has been confirmed through Finite Element Analysis conducted by IKM Tech Team, and confirmed by DNV GL according to the recommended practices and industry standards.
The installation and removal of the IDS is conducted by an IMR vessel, a subsea compensated crane and ROV (Remove Operated Vehicle). The IDS will self penetrate from own weight, before the ROV will apply vacuum and differential pressure inside the suction anchor will force the CAN to its resting position. The removal process will include the same activities in reverse order.
Any subsea supplier may deliver the IDS HPWHH after completing the detailed design and qualification with support from NST.
Currently BHGE is qualified to deliver the IDS HPWHH, while DrilQuip, Cameron, FMC and Aker Solutions require qualification.
The SPS supplier will provide the standard well construction material and services, accept material and services related to the conventional conductor and surface casing installations, which are omitted with the IDS well design
The Compact Flange technology is a high strength static connection used for dynamic applications, historically used in riser systems and pipelines. The concave geometry of the flange will be forced together by the pre-tension of the bolts, causing the bolts never to see any dynamic loads.
The high strength and fatigue life is achieved by fully re-designing well construction material required to establish the well foundation. The critical welds are removed, specially qualified forged material is used to obtain the necessary quality, and the detailed geometry to transfer the loads to the CAN and formation is optimized through FEA analysis.
NST has worked closely together with IKM tech Team and DNV GL to conduct the design and quality assure the results.
