The Cajun Express is a 5th generation deepwater ‘semi submersible’ dynamically positioned rig with capabilities of drilling up to 35,000 feet in 8500 feet of water.
Among preparations and refitting of several systems on board the Cajun Express for its new deployment period in Brazil, a HERNIS HE400 system was selected to replace an existing CCTV system. Initially, in phase 1, HERNIS will deliver the ‘expandable’ HE400 system with 19 Pan Tilt Zoom Camera stations (EX286W and PT9W) for drilling, deck and supply boat operations. The HE400 is replacing an existing system but will continue to utilize the balance of almost 50 cameras from the old system until phase 2 and 3 are complete.
The following features highlight this HE400 system:
1. The system will integrate with the existing “Hotel TV and Entertainment” system, allowing for CCTV viewing throughout the rig.
2. The driller’s cabin is being outfitted with 2 special configurations for the port and starboard assistant driller’s stations. Each station is comprised of a custom joystick control for 4 cameras specific to the assistant driller operations and includes a 10” monitor.
3. A single unique junction box utilizing the new OK150 remote node, replaces existing multiple junction boxes. This solution saves Transocean from having to run hundreds of meters of cable in difficult areas.
Michael Weston, from HERNIS’ Houston office, performed a site survey on the “Cajun Express” with Transocean’s Leighton Collins, IT Supervisor, in October 2009. Michael, working in conjunction with HERNIS and Transocean engineers, completed the design for the new system and the order was received in December with first equipment delivered in February. The balance of phase I is to be delivered in April and installation is due to be completed shortly afterwards. HERNIS Technical Team made innovative contributions that saved the customer cost in labour and materials. HERNIS is proud of the relationship we have established with Transocean that goes back to the 1980’s. We are honoured and appreciate the continuing opportunities to work with Transocean’s personnel to develop an optimum solution for any given project.
