ROSEN Group

Oil and Gas Pipeline Inspection Tools and Services

The ROSEN Group was created to meet the challenging need to inspect complex and sensitive engineering structures such as oil and gas pipeline systems and above-ground storage facilities.

ROSEN operates in more than 100 countries worldwide and offers a full range of products and services to the oil and gas industry covering pipe diameters from 3in up to 64in for any length or configuration (e.g. 1.5D bends, dual diameter pipelines, multi-diameter pipelines).

Pipeline shallow internal corrosion monitoring with eddy current technology

Corrosion affecting the inside of pipelines constitutes a major risk for pipeline integrity. To optimize the process of monitoring shallow internal corrosion (SIC), ROSEN has developed a SIC tool incorporating eddy current (EC) technology. Capable of accurately distinguishing and sizing even minor corrosion features, the tool makes it easy to survey and assess the asset degradation process resulting from corrosion - even in so-called unpiggable pipelines.

Since the EC sensor technology incorporated in ROSEN's SIC tool can be used in bi-directional and robotic inspection tools, it is a suitable inspection method even in the presence of challenges such as high wall thickness, high product flow rates, tight geometrical constraints and in cases where the gas product prohibits ultrasonic technology (UT) measurements. The SIC tool thus provides optimal corrosion growth monitoring in situations where inspection is difficult or impossible with conventional in-line inspection methods.

Detecting metal loss and pipeline wall features in a single inspection run

ROSEN's combined MFL / UT corrosion detection tool RoCorr-MFL / UT employs twin inspection technologies to achieve enhanced performance in defect detection and sizing. Ultrasonic technology (UT) can detect and accurately size defects where magnetic flux leakage (MFL) has limitations (such as large areas of uniformly-corroded metal loss and laminations).

Conversely, MFL can detect and size defects where UT has limitations (i.e. small corrosion pits and internal defects covered by wax or other deposits). With the combined MFL / UT tool, the strengths of both inspection methods provide the most comprehensive detection and sizing results in the market from a single run.

Modular software system for managing and assessing inspection data

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.

Pipeline crack detection and coating disbondment

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.

Smart-pig inspection of pipeline dents

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.
