System Introduction

Overview

Anti-Collision System Components

Key Benefits

The RigSense Anti-Collision System prevents contact between the top drive, racking board, derrick structure and all pipe handling equipment. Constant communication between the RigSense wireless components and display panel ensure that all equipment moves safely within precisely controlled working zones.

RigSense is dedicated to making rigs everywhere safer and more efficient by helping avoid equipment collisions and limit NPT.

System Components

Rotation Sensor:
The rotation sensor measures rotation of the elevator in both directions from a ‘zero’ point.

Bail Angle Sensor:
measures the angle of the bails.

Block Extend Sensor:
measures the distance between the top drive and the back of the derrick.

Rotation Sensor

Description
Uses RFID technology to detect the operational areas in a full 360° rotation.  This positional information is then displayed on the user panel. The rotation sensor is typically installed in approximately one hour and can be fit to any type of top drive with rotation capabilities. The accuracy of the sensor is well within 0.1° and provides real-time feedback to the panel.
Operating Temperature
-35° C - 65°C (-31°F-149°F)
Power Source
Powered by 12 or 24V DC, supplied by crane
Materials
Body material – Ultramid 8333G Hi-Polyamide 6 Seals – ROHS compliant silicon rubber,  60 durometer shore-A, compound # SIM40160
Hazardous locations
Class 1, Div 2, C&D T4 Ex nA IIB T4

Bail Angle Sensor

Description
A wireless component which mounts onto the bails and transmits positional information to the central display panel.The bail angle sensor is typically installed in approximately 30 mins and can be fit to any type of top drive bail arms. The accuracy of the sensor is well within 0.1° and provides real-time feedback to the panel.
Operating Temperature
-35° C - 65°C (-31°F-149°F)
Power Source
Powered by 12 or 24V DC, supplied by crane
Materials
Body material – Ultramid 8333G Hi-Polyamide 6 Seals – ROHS compliant silicon rubber,  60 durometer shore-A, compound # SIM40160
Hazardous locations
Class 1, Div 2, C&D T4 Ex nA IIB T4

Block Extend Sensor

Description
A wireless transducer that monitors the angle of extension between the back of the top drive and the inner face of the derrick.  This positional information is then displayed on the user panel. The block extension sensor is typically installed in approximately 20 mins and can be fit to any type of top drive with extension capability. The accuracy of the sensor is well within 0.1° with real-time feedback to the panel.
