DLM’s specialist design team are always ready to take on a new challenge, so when we were contacted by one of our Offshore cable laying clients to supply three of our new Running Line Monitors, combine the output signals and design a system to integrate this with the clients on board survey suite, we gladly rose to the challenge
The bespoke system comprised three of DLM’s Running Line Monitors along with a Siemens S7-1200 PLC which was installed to allow the client to accurately monitor the output of each RLM. The DLM Design team had to remove the standard RLM display and replace with a PLC that was programmed to accept the tension, speed and distance inputs from three RLMs and combine the inputs into two RS232 outputs. The RS232 output was then connected directly to the Survey Suite.
The PLC had a custom web display page which enabled calibration of the RLMs and configuration of the RS232 output. The S7-1200 was connected to a Siemens key panel with customised tare buttons. These could easily be mounted in a suitable location on the vessel, as it only required an Ethernet cable for communication, thus allowing the user to tare the tension and distance on all three RLMs.
However our service did not stop there and DLM’s offshore survival trained Engineers are now due to attend the vessel to assist in the integration and provide support.
Chris Scrutton, Technical Manager at Dynamic Load Monitoring explained ‘One of the main aims for the DLM design team is to understand customer requirements and build bespoke systems which meet their needs, this ensures the customer is getting the best value for money with a system which performs perfectly each project. We back this up with the ability to attend sites all over the world in order to support our valued clients‘
