Unsurpassed Dependability-KCS Cable Control Technology
The task of laying, burying, and repairing cables in the seabed is vital to the future and reliability of global communications, and must be performed with precision and safety. KCS cable control technology combines know-how accumulated over long years of practical experience with the latest cable handling equipment installed on KDD OCEAN LINK to realize the world's most advanced system. |

| 1) From offshore towards the cable landing station A, one end of the cable is paid out by the ship and "landed". During this phase, the cable is suspended by balloon buoys to prevent possible damage to the cable. Later the buoys are detached, allowing the cable to sink to the ocean floor. |
2) The ship lays cable as it novigates towards the opposite station or a designated point in mid-ocean. |
 |
 |
| 3) At the designated point, the ShiP connects its cable With the terminal of a cable previously laid from station B. |
4) Upon completion of the final connection; the cable is allowed to sink to the ocean floor. |

 |
| 1) Once in the immediate vicinity of the cable fault, KDD OCEAN LINK lowers the searching grapple, a special device that can both cut and seize cables |
2) After the cable is found by the grapple, it is cut in situ and one end is raised and brought onto the ship. |
 |
 |
| 3) A buoy is attached to the end of this recovered cable and then allowed to sink to the ocean floor. KDD OCEAN LINK then searches for the other end of the cable. |
4) After the other end of the cable is recovered onboard and the faulty cable section is removed, the ship connects a replacement cable to the end, and lays cable to the previous buoy. |
 |
|
| 5) Using the buoy, the cable end is recovered and connected to the replacement cable. After completion of testing between the two stations, the cable is released and allowed to sink to the ocean floor. |

Alcatel Submarine Networks, Global Marine Systems Ltd, Kokusai Cable Ship Co., Ltd., and Tyco Submarine Systems Ltd., have joined forces to create a forum to enhance the reliable and cost-effective use of submarine cables in the telecommunications industry by focusing on improved cable system reliability. The fourum, "The Submarine Cable Improvement Groupe(SCIG)" was formed in 1995.
To date the SCIG has developed and distributed guidelines for cable engineering, cable burial depths and for the burial of cable in deepwater. In addition the Group has produced a comprehensive 'Standard Definitions' for terms frequently used in the industry. Please see thae relevant sections within this Information Guide. SCIG intend to extend and update this Guide with future issues.
The Information Guide can be viewed on, and down loaded from, the SCIG web site at www.scig.net. |
