Class 1-4 Rotary Docking (API 17D) Torque Tool

 

The leaders in subsea control

Zetechtics are world leaders in subsea control systems for ROV Intervention tooling to the oil and gas energy markets, providing field proven solutions many of which are continually working in high integrity applications.

 

Overview

  • In-house Motor design for improved performance
  • Planetary gearbox - sprung loaded to low torque
  • Nested, multiclass sockets - fixed class adaptors available
  • The tool also provides torque feedback, turns count, torque range sensing, and visual indication of motor turns

 

Description

The Jupiter Subsea Intelligent Torque Tool - Class 1 - 4 Rotary Docking interfaces with subsea production systems, including project specific interfaces where only the end effector socket is different, and is capable of producing torque up to 2,711N.m (2,000 lbf-ft)

The tool comprises a hydraulic motor, planetary gear box and sprung loaded, nested, multi-class sockets. The tool also provides torque feed-back, turns count, torque range sensing & visual indication of motor turns.

The tool is designed to allow seamless integration with Zetechtics manufactured Jupiter Subsea Control System, however the tool is capable of operating with other systems with suitable hydraulic and electrical interfaces.

When used with a Jupiter 2 Subsea Control System, with the correct software version and configuration, it is possible to determine direction of rotation from the internal quadrature sensors. This is encoded on the single turns count output using Zetechtics’ proprietary turns count electrical interface, together with gear box status.
