INTECSEA and Innospection Ltd announced today the launch of FlexIQ, a complete offering in the arena of flexible riser integrity management from the strategic alliance between INTECSEA and Innospection.
This partnership redefines the approach to flexible riser integrity management by offering clients best in class inspection and computational simulation techniques as part of an overall Integrity Management Framework. In turn, this leads
to a significant improvement in understanding of operational risk and enables a fully integrated service for inspection, analysis, and data management.
Central to the value and distinctiveness of FlexIQ are the state-of-the-art and proprietary inspection capabilities of MEC-FIT? and numerical simulation capabilities of FLEXAS?. MEC-FIT? inspection combines DC magnetic and Eddy Current
fields to detect damage in up to three metallic layers, including cracking, pitting, and general corrosion, as well as wire misalignment and gaps, all without requiring the riser annulus to be flooded. This unparalleled level of
inspection data is then incorporated into high fidelity 3D finite element models for simulation with FLEXAS?, a multi-body nonlinear dynamic substructuring solver. FLEXAS? conquers the computational limitations of other industry
simulation software, resulting in high resolution fatigue spectra and accurate fatigue life predictions.
By combining these capabilities with industry-leading annulus testing and a formal risk-based approach to flexible riser risk assessment and life extension, FlexIQ delivers all aspects of flexible integrity management through a single
provider.
Commenting on the partnership with Innospection and the FlexIQ offering, INTECSEA president Neil Mackintosh said, ’Innospection is a perfect partner for INTECSEA in the offshore inspection space. We feel the alliance is a natural
extension of our mission to provide innovative, independent solutions across the project lifecycle. We are confident our advanced FLEXAS? technology, combined with the unparalleled inspection capability of Innospection, will provide
increased understanding, and reduced uncertainty and cost for clients in the arena of flexible risers. The bottom line is that FlexIQ delivers insight, not just data.’
Andreas Boenisch, Managing Director of Innospection said, ’In decades of industry experience, with the majority in offshore asset inspection and integrity assessment, I have found the complexity of flexible risers to be unique. Reliable
integrity assessment and remaining life evaluations of flexibles require focused and advanced technology and innovation, combined with expertise.’
At both Innospection and INTECSEA, these attributes are present. The resulting combination of capabilities is FlexIQ, which provides operators of flexible risers the unique opportunity to work with a partner capable of providing the
absolute best possible data and analysis.
FlexIQ offers clients a complete flexible riser integrity management program. FlexIQ is available as discrete packages or as a full service offering, dependent on clients’ needs.

MEC-FIT INSPECTION
The MEC-FITTM (Magnetic Eddy Current Flexible Riser Inspection Tool) inspection technique was developed in response to market demand for general riser and flexible riser inspections operated from offshore installations. At the same time,
Innospection has also gathered experience in applying this technology to subsea inspection of mooring lines and umbilicals.
MEC-FITTM offers rapid external scanning with the ability to penetrate into multiple armour layers. It features a patented inspection technique which combines the direct magnetic field lines with eddy current field lines, allowing for
deeper penetration into the ferritic steel material.
The key capability of the electromagnetic MEC-FITTM technique is the detection of localized material defects such as wire cracks, wire ruptures and corrosion / wall loss beneath the coating.
This technology has been proven in different verification trials with a number of major operators, and has been used successfully on flexible riser as well as horizontal pipe sections.
Various tool types based on the MEC- FITTM technique are available to allow deployment directly from the installation platform or floating structure, via ROV or diver support.
Combined DC magnetic and eddy current fields to detect single or multiple wire damage in up to3 metallic layers.
Detects cracking, pitting, general corrosion, and wire misalignment and gaps.
Mapping of wire layers and identifying details of individual findings.
No requirement for annulus to be flooded.
Deployment from topside or ROV.
FLEXAS SIMULATION
Flexible risers are complex multi-layered structures with contra-wound tensile armour wire layers. Accurate computation of wire stresses and fatigue life requires capturing the local layer nonlinear kinematics within the global dynamic
simulation of the flexible riser. This necessitates inclusion of high fidelity 3D finite element models of the flexible in a large scale nonlinear dynamic simulation with long duration irregular wave inputs. Current industry approaches
lead to over-conservative and unreliable service- life predictions; and their inability to implement damage data in a meaningful way leads to reactive maintenance and high-cost untimely replacements.
FLEXASTM overcomes current computational constraints through advanced computational methodologies. The computational efficiencies provided by FLEXASTM solver enable the direct inclusion of high fidelity 3D finite element models into the
large scale, nonlinear dynamic simulations with long duration irregular wave inputs. This results in a high resolution fatigue spectra and accurate fatigue life predictions. Furthermore, this framework allows detailed inspection
data (damage, flooding, and corrosion)to be captured in the 3D models and incorporated into the simulations, enabling a comprehensive risk-based strategy to be developed for integrity management.
FLEXASTM has been qualified by DeepStar and ExxonMobil in independent validations against numerical and experimental benchmarks and is considered the leading flexible riser simulation capability by Subject Matter Experts (SMEs) at
multiple major operators.
