Objectives To perform a feasibility study and cost-benefit analysis that will demonstrate the applicability of the SubCTest NDT system (developed in the preceding SME RTD project SubCTest ) on a prescribed sub-sea structure. To set a baseline for assessing the overall performance of the SubCTest system relative to conventional approaches to NDT, with regards to installation and setting as well as in-service performance costs and benefits To establish the validation tools that will be used in the demonstration of the SubCTest NDT system. To provide industrial validation of the SubCTest System - a reliable NDT defect detection System for offshore sub-sea engineering structures where conventional NDT approaches are considered inappropriate. This industrial validation will be performed on real dock-side conditions, through a series of trials on prescribed structures and the system comprises hardware and software. To evaluate the performance of the SubCTest System for the purposes of reliability and robustness via characterisation of the data acquired through the technologies involved in the previous call. The system should work with no loss of functionality at any instance. In the event that a malfunction occurs, it must be clearly reported and the reason identified. A solution must then be forthcoming and implemented. To define procedures for installation of the ACFM and LRUT system. The procedures will be prepared as instructions manual. It should act as a guide for application on possible structure geometries, covered by the SubCTest System. To develop the exploitation strategy that will maximise the value of the project for the SMEs through the adoption of the SubCTest System as the state-of-the-art NDT solution for sub-sea structures, in oil/platforms sector. A complete market analysis – scope of application and potential sales volume - together with a detailed verification of the interest generated in the SubCTest System from various industry sectors. To enable economic objectives by way of improving the competitiveness of a group of European SMEs operating in the world-wide oil and gas industry by exploiting the technology developed within the project.
