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.

Abstract: The invention concerns an integrity monitoring system for monitoring integrity of at least a part of a stationary structure. The system comprises 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, where the movable object comprises a transmitter, and 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 comprises the part of the stationary structure to be monitored and the vibration sensor is arranged to sense vibrations within the monitoring site. The computer comprises hardware and software for comparing the vibration data with the position as a function of time data.
