AJC has two separate agreements for the provision of marine maintenance services. As part of these agreements, the AJC has access to cable ships, expertise and associated depots in which spare cables, consumables and submarines are stored. Operating costs paid by the cable owner who requests repair to the cable carrier. ACMA is the sole purpose for cable repair and maintenance in the Atlantic, there are 61 members of the telecommunications industry, electrical cables and oil and gas. In the maintenance of the Yokohama area, KCS cooperates with KT Submarine in Korea and SBSS in China, with which KCS maintains Yokohama Zone. Similarly, if not all area vessels are available, there is a framework for mutual assistance between areas on the basis of the Pacific and Indian Ocean Cable Maintenance Agreement (PIOCMA). Table 17.1 shows a comparison between the two types of maintenance contracts. When the original coaxial cable systems were introduced more than 40 years ago, each cable owner entrusted a cable operator with the individual maintenance of their own cable. The cost of YZ ships and rovs is based on a fixed fee. These supplements are allocated to an accounting unit calculated according to a formula agreed by the AD. This method is a very fair and reasonable method of allocating costs and reduces the unit price when new cables enter the agreement.
Note that software providers sometimes make the difference between maintenance and support. Maintenance may be limited to your ability to get upgrades for the product. However, support usually refers to your ability to get support (phone, web-based, etc.) if you have a problem or a question regarding the use of the software. Make sure you understand what your provider means through maintenance and support. In addition, for some vendors, maintenance only covers intermediate versions and patches, while larger upgrades must be paid separately. Much of the submarine systems are in addition to private or unionized maintenance contracts for the sea, where they have access to strategically located repair vessels in the area, for a quarterly fee called parking fees. Because cable defects are rare, these vessels are shared by many cable systems, and the likelihood of more simultaneous errors than available vessels is relatively low. Pacific Cable Maintenance Agreement divided into several regional areas (Yokohama, North America…) (PIOCMA) Since 1967, submarine cables have been buried as a means of eliminating cable breaks caused by fishing activities on continental plateaus and in some parts of the world to signal water depths of 1,500 metres.
The first commercial use of a “sea flight” was made with AT-Tes Sea Plow 3, which equipped TAT 3 and 4 off New Jersey along the length of the continental shelf. Sea Plow 3 was first operated in 1967 by CS John Cabot and has been operated by CS Vercors since 1975. TAT 3 and TAT4 were renovated in 1967 and TAT 5 was the first cable buried in the two continental plateaus of Spain and the United States in 1969. Then the funeral was generalized everywhere possible; As a result, funerals reduced overall error time when fishing activity increased sharply. Since the inauguration of the world`s first Trans-Pacific Submarine Cable (TPC-1) in 1964, Kokusai Cable Ship Co., Ltd. (KCS) has maintained almost all international submarine cables in the Asia-Pacific region. As the wiring operator, KDDI OCEAN LINK, dedicated to the maintenance of the Yokohama area for the Asia-Pacific region, KCS has been helping to maintain the stability of international communications in the region since the initial phase.
