International Classification

0

Classification is an important method for assessment of ship’s technical conditions, by means of whether the ship is classed and what grade the class is, directly influencing the ship’s freight and insurance (i.e. the trust level the cargo owner and insurance company have in the ship), and also affecting the ship’s purchase price or rent at the time of dealing or chartering. Comparing with non-classed ships, a classed ship has considerable advantages in ship transactions, shipping cargo collections and insurance rates.After years of development, CCS succeeds in keeping pace with the international counterparts in ship survey business, obtaining recognition and authorization from the administrations of more and more countries or regions to carry out statutory surveys and issue corresponding certificates on their behalf. The classification surveys provided by CCS and the assigned class symbols and notations have been recognized by the insurers both at home and abroad and the ships classed with CCS can enjoy the same preferential insurance treatment for the cargo carried.CCS owns a team of well-experienced exclusive surveyors with high educational level. CCS has set up branches/offices at major ports along China’s coast and the Yangtze River and in countries/regions in Asia, Europe, America, Africa, Oceania etc., shaping up a global service network.CCS carries out classification surveys and issues corresponding certificates strictly according to the quality system requirements to ensure that the entire service process is performed under controlled conditions and the survey quality is guaranteed. CCS has become one of the best member societies of IACS in terms of good PSC quality record of CCS-classed ships.With the rapid development of the shipping and shipbuilding industry, the CCS classification fleet has expanded. A number of very large, high-tech, and high-value-added ships (LNG, VLCC, VLOC, 21,000-TEU very large container ships, 210,000-dwt bulk carriers, 400,000-dwt ore carriers, etc.) have joined the CCS fleet, making it more international and modern. By the end of 2019, in terms of international voyage fleet, 4,200 ships were classed with a gross tonnage of 1.12 and an average age of 9.5 years.CCS accelerates the technology research on high value-added ships, and completes the direct calculation and standard formulation of large-scale thin-film LNG carriers, the research and development of ship types such as LNG dual-fuel bulk ore ships, LNG bunkering ships, LNG-powered large tankers, and oil-electric hybrid bulk ore ships, and on-board verification of the applicability of the rules for large luxury cruise ships. CCS makes greater efforts to develop service products and provide customers with precise services. Also, CCS carries out structural optimization and energy efficiency upgrades for large ore carriers, bulk carriers, and product oil tankers, and provides ship emergency response services and ship condition assessment procedures (CAP). CCS has promulgated the “Guidelines for Ship Remote Surveys”, to promote remote survey technology, provide customers with efficient and flexible survey services, and effectively respond to the impact of the COVID-19 epidemic on the classification business.   (20,000-TEU very large container ships “COSCO SHIPPING SCORPIO”)   (308,000-dwt oil tanker “XIN HAI YUAN”)   (62,000-dwt multi-purpose pulp carrier “COSCO SHIPPING EXCELLENCE”)   CCS is committed to providing excellent services to all circles in the field of ship classification.

Class transfer and initial classification surveys

0

The class transfer survey of a ship in service refers to the inspection on compliance of a ship with an IACS class that has already been in service and applies for transfer to the CCS class, before the CCS class is assigned and the classification certificate is issued, in order to confirm that the documents, design of structure and equipment, configuration and technical status, and management conform to the CCS classification specifications, rules and other technical requirements recognized by CCS.The initial classification survey of a ship in service refers to the inspection on compliance of a ship without an IACS class that has already been in service and applies for the CCS class, before the CCS class is assigned and the classification certificate is issued, in order to confirm that the documents, design of structure and equipment, configuration and technical status, and management conform to the CCS classification specifications, rules and other technical requirements recognized by CCS. CCS will consider arranging pre-classification inspection and drawing approval for ships based on the actual technical status of the ship and the situation of the existing classification society.When transfer of class and initial classification are applied for, they can be carried out in conjunction with the normal survey cycle of the ship. It is recommended that the customer contact CCS in advance. CCS will fully consider the ship schedule and voyage plan to give advice to the ship owner/management company, so that the survey is conducted at a more suitable time, port or shipyard. For ships to apply for initial classification survey in CCS, the below procedure needs to be followed:   For more details, please contact us:Tel.: 0086-21-38103599E-mail: survey@ccs.org.cn More convenient services:EContact CCS offices/branches

The China Classification Society (CCS) is the only professional organization engaged in the ship classification survey business in China and a full member of the International Association of Classification Societies (IACS). CCS formulates classification rules for ships and offshore installations and is entrusted by China MSA to prepare technical regulations for ships and offshore installations. CCS has scientific research information institutions such as the Rules and Technology Center (CCS Shanghai Rules & Research Institute), CCS Wuhan Rules & Research Institute, Offshore Engineering Technology Center, Technology Research and Development Center, Science and Technology Innovation Test Center, and Information Center.Since its establishment, CCS has gradually formed a system of rules and regulations for sea-going vessels (including ocean-going fishing vessels), inland vessels, offshore mobile drilling vessels, fixed platforms, and container ships through the study of international advanced technical standards and the accumulation of experience in the process of plan approval and survey. The system of rules and guidelines for ships covers high-tech ship types such as very large crude carriers (VLCC), very large container ships, very large ore carriers, membrane liquefied natural gas (LNG) carriers, and large vehicle carriers, supporting the development of the shipbuilding industry in China, and promoting the safety of water transport.CCS concentrates its efforts on the research of key technologies for large and high-tech ship types and for offshore engineering, green smart technologies, and new energy application technologies, and has issued standards such as the Rules for Green Eco-ships, Rules for Intelligent Ships, and Rules for Cruise Ships. The rules for the structure of bulk carriers and oil tankers have passed the International Goal-based Ship Construction Standards for Bulk Carriers and Oil Tankers (IMO GBS) audit without defects, and the audit results are the best among the members of the International Association of Classification Societies. Fruitful results have been achieved in the research of key technologies such as intelligent ships/unmanned ships, application of LNG power on water, very large container ships, very large ore ships, LNG carriers, mobile platforms and floating units, reaching the international leading or advanced level. A large number of very large, high-performance, high-value-added ships and offshore mobile platforms have joined CCS. The system of CCS rules and standards and the technical service capabilities are widely accepted by international and domestic industries.CCS continues to increase its influence in the international maritime community, providing strong technical support for the Chinese government to participate in international maritime affairs, safeguard national maritime rights and interests, and support the development of related industries. CCS actively participates in the formulation of international maritime technical standards and submits more than half of the Chinese proposals to the International Maritime Organization on an annual average basis. CCS has played an important role in the formulation of international maritime technical standards including the Ballast Water Management Convention, Hong Kong Convention, Common Structural Rules for Oil Tankers and Bulk Carriers, Energy Efficiency Design Index for new ships, Code on Noise Levels on Board Ships, Polar Code, IGF Code, and asbestos-free thresholds, safeguarding the interests of the country and related industries, and making great contributions to the development of international maritime technology.In the future, CCS will continue to improve its capabilities in scientific and technological innovation and leading development, to comprehensively form a scientific and technological work system with the ability for strong independent innovation, high-level rules and standards, and scientific evaluation and experiment, and fulfil the mission of “safety, environmental protection, and creating value for clients and the society”. For more details, please contact us:Sea Ship: CCS Shanghai Rules & Research Institute, Tel: 021-61089200, E-mail: ccssr@ccs.org.cnRiver Ship: CCS Wuhan Rules & Research Institute, Tel: 027-85822350, E-mail: ccswra@ccs.org.cn Offshore Engineering: Offshore Engineering Technology Center, Tel: 022-62022888, E-mail: ot@ccs.org.cn
