IN-PIPE INSPECTION ROBOTS

SIMASRobot

The Challenge

Pipe leakage, cracks and internal defects in pipelines, structures, confined spaces and others assets are usual problems for the inspection area in the energy sector.

New non-destructive test technologies are applied to foresee and evaluate these problems.

Our Solution

This robotic system performs visual inspections and makes height measurements of root penetration welds and tubular structures between 6 “and 15”.

The robot features a high definition camera with pan/tilt movement and laser projection. With its own image processing technology (with a 0.03mm uncertainty in height measurement), SIMAS can be used for visual inspections on linear and curved pipelines, including inclines.

Like its larger version, it is modular and can be coupled to various modules such as: MFL, ultrasound, geometric, gamma-ray, among others.

DESENVOLVIMENTO DE UM ROBÔ PARA INSPEÇÃO INTERNA EM TUBULAÇÕES NÃO PIGÁVEIS

Abstract
Welding of submarine tubular structures is often a challenge for the company responsible for this task. This process must attend highly stringent standards and it is subject to various inspections to verify the compliance. Failure to comply with the standards results in reworking and, sometimes, the definitive loss of part of the structure, generating costs for the producing companies and to the executors. Once the root of the weld and the first filling layers are made, the robot is used for internal visual inspection and for measuring the height of penetration of the root of the weld. If the root of the weld presents excessive penetration (a failure to comply with the standard), the robot is able to analyze the penetration height and inform the inspector in real time. This paper presents the steps of developing a robotic vehicle to perform weld inspections of underwater tubular structures and non-piggable pipes, as well as their field tests and results.
