pipe and pipeline failure and leak sensors, fiber optic sensors for detecting leaks or failures in surface or sub-surface pipelines, tubulars, pipe strings or pipes

engineering services, namely, field and remote investigation of surface and sub-surface pipe and pipeline failures and leaks to industry organizations

data acquisition system for use in connection with pipelines and wellbores only that relies on optical inteferometry to measure acoustic signals, vibrations, temperature and dynamic strain generally and consists of fiber optic sensors, optical fibers, optical interrogators that generate light pulses for transmission along optical fibers, clamps for clamping fiber onto tubulars, and software that analyzes the electrical signals output by the optical interrogators, and generates a report for the user on what the measurements taken by the system mean
