Subsea processing is rapidly evolving; new technologies are routinely proposed for field application. Introduction of these new technologies, with limited or no previous operating history in the proposed environment, necessitates systematic design verification and validation. Generally, these technologies are not covered by existing rules, regulations, codes or procedures. Therefore, a different approach is required to help qualify their intended function. This paper describes a new qualification process ABS recently published. It also illustrates using the new technology qualification (NTQ) process for subsea compressors, as an example. The NTQ process can be used for qualifying other industry applications, from data analytics engines to new inspection technologies.
The NTQ process is divided into five stages: Feasibility Stage, Concept Verification Stage, Prototype Validation Stage, System Integration Stage and Operational Stage. These stages are aligned with the typical engineering product development phases of to-be-qualified equipment; and are compatible with industry Technology Readiness Levels Approaches (e.g., API RP 17N, ISO 16290). The main activities in each stage include risk assessments and engineering evaluations. These activities build, each upon the next, to determine qualification criteria and means to determine compliance with them. Results of risk assessments and engineering evaluations may lead to design improvements, or modifications to system requirements.
The proposed methodology affords industry a systems engineering-based approach for new technology qualification. The methodology is derived from many years of experience in design verification and validation of new/novel concepts for the offshore industry. The NTQ process has been successfully implemented for Independent Third-Party Review of High Pressure High Temperature designs. Lessons learned from these projects have been incorporated into the ABS Guidance Notes on Qualifying New Technologies. Upon completing the necessary requirements for each NTQ stage, a Statement of Maturity letter is awarded to the technology owner for demonstrating technology readiness for that stage. The Statement of Maturity can assist vendors in demonstrating feasibility and level of maturity for funding – as well as providing confidence to project partners, potential clients and regulatory bodies.
A differentiating feature of the new methodology is the iterative process within each qualification stage to assess the ability of the new technology to perform intended functions in accordance with defined performance requirements. Using systems engineering principles that are easily incorporated into the existing engineering process – and recognizing technology maturity at various development phases – is unique and valuable. Another key benefit of the method is the seamless transition from technology qualification, for equipment manufacturers, to class approval of an asset for owners/operators incorporating the new technology.
