## Abstract

A method for capturing a tensile force exerted during the pulling of a pipe or line during installation, includes capturing a strain on the pipe or line via one or more sensors arranged on the pipe or line. Multiple strain sensors may be arranged such that they are offset at various angles across the circumference of the element being installed. One or more sensors may be mounted to a towing head for pulling the pipe or the line during installation.

## Claims

### Claim 1

A method for detecting a tensile force exerted while pulling a pipe or a line during installation, characterized in that the strain on the pipe or the line is detected via one or more sensors arranged on the pipe or the line.

### Claim 2 (depends on 1)

The method according to claim 1, characterized in that one or more sensors are mounted to the pipe or the line.

### Claim 3 (depends on 1)

The method according to claim 1, characterized in that one or more sensors are mounted to a towing head, which is used to pull the pipe or the line during installation.

### Claim 4 (depends on 1)

The method according to claim 1, characterized in that the temperature in the area of the sensor is detected.

### Claim 5 (depends on 1)

The method according to claim 1, characterized in that the strain on the pipe or the line is detected by circumferentially distributed sensors.

### Claim 6

A device for detecting a tensile force exerted while pulling a pipe or a line during installation, wherein the device includes a sensor for detecting the strain, characterized in that the sensor is connected to a towing head of a pulling device, the strain sensor is connected to a recording device, and/or the sensor is connected to allow for the wireless communication of signals.

### Claim 7 (depends on 6)

The device according to claim 6, characterized in that the sensor is at least partially mounted to the towing head.

### Claim 8 (depends on 6)

The device according to claim 6, characterized in that a temperature sensor is arranged at the towing head adjacent to the sensor.

### Claim 9 (depends on 6)

The device according to claim 6, characterized in that the sensor includes a bar at one of its ends, which is designed such that it can be connected to the pipe or the line.
