J Tube Pull Tension Monitoring System JT-TMS

The DLM J-Tube Pull Tension Monitoring System is a unique set of Load Monitoring equipment designed specifically for use in offshore cable installations on Wind Farm platforms.

The system monitors the Load using a Tensile Load Link or Load Pin mounted on/in a sheave block connected to the pull-in Winch cable.

A local rugged display enclosed in a Peli case is used to display the load on the offshore platform, which has a wireless link to a slave display designed to be mounted on the
cable laying vessel.

The system comes complete with an audible alarm on the Peli display, RS232/RS485 retransmission options on the slave display and also a “bolt-on” Data logger option offering the ability to log data over time and view load trends in graphical format.

Key Features

  • Robust Offshore design with display mounted in peli cases
  • Wireless transmission of signals to Load cell and then back to remote display on vessel
  • Data Logging
  • RS232 retransmission on vessel display for connection to survey
  • Long battery life with removable battery packs
  • Use of multiple hand held displays to one Load cell if required
  • Wireless connection to multiple vessel displays

Applications

  • Offshore windfarm power cable installations
  • cable laying operations
