Integrity monitoring system and a method of monitoring integrity of a stationary structure
First Claim
1. An integrity monitoring system for monitoring integrity of at least a part of a stationary structure, the system comprising:
- at least one vibration sensor for sensing vibration as a function of time,a computer comprising a processor,transmitting means for transmitting vibration data from the vibration sensor to the computer,means for acquiring, via a transmitter of a movable object, and transmitting position as a function of time data of said movable object to said computer when said movable object is within a selected distance to a monitoring site,wherein the monitoring site comprises the part of the stationary structure and the vibration sensor is arranged to sense vibrations within said monitoring site, said processor being programmed to execute instructions to compare the vibration data from the vibration sensor with the position as a function of time data from the transmitter of the movable object, andwherein the means for acquiring and transmitting position as a function of time data is independent from the at least one vibration sensor.

Abstract
An integrity monitoring system for monitoring integrity of at least a part of a stationary structure includes a vibration sensor for sensing vibration as a function of time, a computer, transmitting means for transmitting vibration data from the vibration sensor to the computer, means for acquiring position as a function of time data of a movable object, such as a vessel, a vehicle or a digging tool. The movable object includes a transmitter transmitting the position as a function of time data to the computer when the movable object is within a selected distance to a monitoring site. The monitoring site includes the part of the stationary structure to be monitored and the vibration sensor is arranged to sense vibrations within the monitoring site. The computer includes hardware and software for comparing the vibration data with the position as a function of time data.
