3. Deployment Procedure
3.1. Mechanical and Electrical Interfaces
The junction box end plate has 10 SeaCon connectors, numbered J1 through J10. The steps
below outline the installation of cables on the JB SeaCon connectors:
- Check that the JB output ports are disabled.
- Check that the connectors are clean and free of dust or debris.
- Install o-ring in the face of the SeaCon connector. Ensure that the o-ring is
properly lubed, that there is no dust or debris on it and that it is seated properly in
the connector.
- Align the key slots of the cable connector with that of the JB SeaCon.
- Keeping the key slots aligned, push the cable connector onto the JB SeaCon. If
the key slots are not properly aligned, slowly rotate the cable connector until it
slides onto the JB SeaCon.
- Turn the threaded portion of the cable connector until it is hand tight.
The steps below outline the installation of cables to the ODI Remote Operated underwater
Vehicle (ROV) connector:
- Check that the power supply to the JB is not live.
- Check that the connector faces are clean and free of dust or debris.
- Align the key slots of the connectors.
- Push the cable into the ODI ROV receptacle.
- Ensure that no yellow is visible on the side of the ODI ROV connector. If yellow is
visible a proper mate was not made. In this case remove the connectors and
restart the process.
Precautions must be taken so that the weight of the cables is not born by the connectors and
suitable strain relief techniques must be employed to prevent damage to the connectors.
Care must also be taken to prevent kinking of the cables.
3.2. Pre-deployment Testing
Prior to deploying the JB confirm the following:
- JB powers up.
- All internal JB network devices can be pinged via the primary and secondary
uplinks.
- JB ports can be controlled via Telnet and expected voltage outputs are seen at
the ports.
- Communication links can be established on serial ports (if applicable).
- Communication links can be established on 100BaseT ethernet ports.
During this testing, the JB must be secured in a manner that prevents it from rolling on the
surface that it is placed upon. The NEPTUNE Lifting Frame Assembly is an option for this.
