Current Collaborative Projects:

RISERTEST
Development of a guided long-range ultrasonic inspection system for the examination of offshore subsea risers, steel catenary risers (SCRs) and flowlines.

PIPESCAN
Development of systems for the inspection of metal pipelines buried underground, in concrete, in water or covered with coatings.

OPCOM
Development of ultrasonic guided wave inspection technology for the condition monitoring of offshore structures.

LRUCM
Long range ultrasonic condition monitoring of engineering assets. Visit website: www.lrucm.eu.com

TankInspect
Condition monitoring of large oil and chemical storage tanks using ultrasonic guided wave tomography without the need to empty and clean the tanks.

Development of phased array and swept frequency guided wave long range ultrasonic techniques for fitness for service assessment of pipe corrosion.

A key technology for direct assessment of buried pipelines - validation and enhancement of long range guided wave ultrasonic testing.

Core Research Projects

0401-7 Guided wave phased array technology for assessing corrosion in pipelines

Objectives

  • To find the most effective techniques for focussing guided waves into one region of the pipe.

  • To determine the scope of the focussing technique for a range of pipe geometries.

  • To assess the potential for sizing corrosion defects using modelling techniques for focussing of guided waves.

0401-15 Validation of theoretical models for focussed/phased array ultrasonic inspection of clad pipes

Objectives

  • To validate theoretical models for focussed and/or phased array ultrasonic techniques for the inspection of clad pipes.

  • To demonstrate detection performance of focussed and/or phased array ultrasonic techniques for clad pipe.

0401-18 Piezodiagnostics - smart structural diagnostics using piezo-generated elastic waves

Objectives

  • To develop a smart piezo-diagnostics technology with the potential of long distance operation (wave propagation for distances greater than 1km) thereby overcoming the requirement for close proximity between the wave-generator, sensors and potential defects.

  • To develop an associated data processing methodology enabling real-time monitoring, multi-damage detection and it s precise identification (dispersed locations and intensities).

  • To develop a prototype installation for remote monitoring.

  • To evaluate the developed monitoring system, in laboratory and industrial conditions.
