ROSEN Group Pipeline and Tank Inspection
The ROSEN Group provides a full range of inspection services for complex and sensitive engineering structures such as oil and gas pipeline systems and above-ground storage facilities.
Operating in more than 100 countries worldwide ROSEN’s products and services to the oil and gas industry cover pipe diameters from 3in up to 64in for any length or configuration (e.g. 1.5D bends, dual diameter pipelines, multi-diameter pipelines).

EMAT crack detection and coating disbondment tool (ROCD²)
Electro Magnetic Acoustic Transducer (EMAT) technology is based on electro-mechanical conversion produced when an eddy current is applied within a static magnetic field. The resulting Lorentz forces and magnetostriction result in an interaction between the EMAT and the metal surface generating an acoustic wave within the material, eliminating the need for liquid couplant.
The acoustic wave that propagates within the pipe wall is dependent on the dimensions and properties of the pipe material. Therefore, the presence of SSC and other crack features will disturb the guided-wave in such a way as to produce a reflection resulting in an echo. This echo can be detected and measured.
ROSEN’s high-resolution tool RoCD2 provides the above mentioned approach. The tools service is based on a unique and highly effective implementation of an EMAT to induce guided acoustic waves within the pipe wall regardless of the pipeline contents.
The result is a high quality and reliable signal precisely controlled in wave length and frequency limiting detection to cracks and crack colonies and minimizing detection of other intrinsic anomalies of the pipeline. In addition, the technique is used to collect coating disbondment information.
Pipeline dent detection
Based on 25 years of experience in ILI technology, ROSEN has developed a unique tool for characterizing and sizing dents. RoGeo•Xt incorporates high-resolution technology combining a touch-less electronic measuring system with the conventional calliper arm tools. This dynamic compensation technology provides highly accurate results both under dynamic and static conditions.
The tool is based on an innovative concept: it combines a traditional mechanical caliper arm with an electronic distance measurement system, thereby optimizing measurement accuracy and providing 100% circumferential coverage. Traditional mechanical caliper tool designs generate position signals on the basis of the movements of a mechanical arm.
Since increased tool speeds mean that the mechanical arm can lose contact with the inner pipe wall while abrupt changes in the internal surface may lead to inaccurate measurements, this puts severe limitations on inspection speed. RoGeo•Xt overcomes these difficulties thanks to its ‘mechatronic’ design.
Combined MFL / ultrasonic corrosion detection
ROSEN’s inspection tool RoCorr•MFL/UT employs twin inspection technologies to achieve enhanced performance in defect detection and sizing. RoCorr•MFL/UT tools combine the latest generation of MFL technology and state-of-the-art ultrasound technology (UT). This advanced range of high resolution tools is based on a unique modular concept which allows the tools to be used in a variety of specialized configurations.
Advanced software solution
The primary objective of an integrity program is to maintain the pipeline in a fitness-for-purpose condition and in a safe and cost-effective manner. Standards and codes of practice are available which provide clear guidance for the practical implementation of pipeline integrity management in a logical and consistent manner.
ROSEN has developed a suite of software tools which meets the technical and functional demands. The ROSEN Asset Integrity Management Software (ROAIMS) is made up of a number of functional modules that can be combined to configure different integrity management applications.
Following an initial audit of an operator’s specific requirement the system can be customized as needed, ranging from a simple data storage / repository to a comprehensive integrated integrity management software solution.
