Abstract

The present invention relates to a latch monitoring system for use on a drilling platform adapted for creating active feedback for the active latches on at least one fingerboard, comprising a CCTV system for providing ‘eyes around the corner’ for the driller by positioning camera’s such that they have a full view on the latches and comprising advanced video analytics algorithms to analyze and report active latch position. comprising at least one HD camera. The at least one camera is mounted on a hydraracker, in particular on the upper and middle arm thereof and comprises redundant camera’s, and a dedicated display in driller cabin to display live footage from upper and lower fingerboards.

This patent has been granted regardless of the attached result of the research into the state of the art and written opinion. The patent corresponds to the documents originally submitted.

Latch Monitoring System

The present invention relates to a latch monitoring system for use on a drilling platform.

On drilling platforms, pipes to be drilled are stored and kept in place individually by so called fingerboards. These fingerboards comprise latches that define the individual positions of the pipes and release the pipes when needed.

For safety reasons, no pipes may be released unintended, and the position of the latches should therefore be monitored. However, in state of the art systems, a fundamental mechanical design is wrong due to lack of feedback, and there are too many latches to rely on sensors only.

A common industry solution is a human spotter on the drill floor, which is not only expensive and dangerous but also disadvantageous because humans are not good at repetitive tasks.

It is therefore a goal of the present invention to increase safety and reduce operational costs.

The invention does so by creating active feedback for the active latches on at least one, but preferably multiple - such as an upper and lower - fingerboards.

In an embodiment, a CCTV system provides eyes around the corner for the driller, which is currently available. The system does so by positioning the cameras such that they have a full view on the latches.

In a further embodiment the system comprises advanced video analytics algorithms for analysis and report active latch position.

The system may include at least one HD camera. The camera may be mounted on a hydraracker, in particular on the upper and middle arm. There may be redundant cameras, for instance up to 8.

The system may further include a dedicated display in driller cabin to display live footage from upper and lower fingerboards. Additionally, the system may include a recorder to record live operation. The system has a limited number of components or reduce potential failing or system significant.

The system may include a data processor, configured for applying Deep Learning methods and Machine Learning algorithms, and / or advanced temporal post processing methods for robustness and speed. It may further include virtual calibration to cope with the moving and rotating hydraracker.

Figure 1 shows a dedicated display in a driller cabin according to the invention.
