CB3164-83 was formulated on the basis of ISO/DP5572. During its implementation, it played an active and important role in unifying the engineering language of computer-aided design and construction procedures in my country's shipbuilding field and accurately transmitting calculation information. In order to complete the shipbuilding industry standard system and achieve integration with international standards, the revision of CB3164-83 based on the principle of equivalent and equivalent adoption of international standards is an effective way to achieve integration with international standards. The numbering method specified in ISO5572:19878 Shipbuilding and offshore structures, equipment and structural unit numbering, is an important technical basic standard for computer-aided ship design and construction. From the current situation in my country's shipbuilding industry, computers have been widely used to assist in ship design and construction. Therefore, the revision of CB3164-83 on the basis of equivalent adoption of ISO5572:1987 will play an active role in unifying the engineering language of computer-aided ship design in my country's shipbuilding industry and strengthening domestic and foreign scientific and technological exchanges. The main changes between this revision and the previous version are as follows: 1 CB 3164-83 stipulates that the establishment of stations in the vertical line length diagram is 10 or 20 stations. This revision is 10, 20 or 100 stations; 2 The "4-position", "5-rib" and "7-other transverse members" of CB 3164-83 are combined into "4-rib position", which is consistent with international standards.
This standard will be implemented from August 1, 1998. At the same time, it will replace CB 3164-83. This standard was proposed by the Ship Foundation Sub-Technical Committee of the National Technical Committee for Standardization of Marine Ships. This standard is under the jurisdiction of the Comprehensive Technical and Economic Research Institute of China State Shipbuilding Corporation. The drafting unit of this standard is: Comprehensive Technical and Economic Research Institute of China State Shipbuilding Corporation. The main drafter of this standard is Kang Yuan.
This standard was first issued in 1983.

ISO Foreword
ISO (International Organization for Standardization) is an international organization of national standards bodies (ISO member bodies). The development of international standards is carried out by ISO technical committees. Each member body has the right to participate in the committee if it is interested in the subject of a technical committee. International organizations, both governmental and non-governmental, that have relations with ISO may also participate in this work. Draft international standards adopted by technical committees are sent to member bodies for approval before being approved as international standards by the ISO Council. According to the ISO standard-setting procedure, a draft international standard must be approved by at least 75% of the member bodies to become an international standard. International Standard ISO5572 was prepared by ISO/TC8, Technical Committee for Superstructure and Offshore Control. Users should note that all international standards are subject to frequent revision. Unless otherwise specified, the other international standards referenced in this standard refer to the latest versions.

Numbering of equipment and structural elements in This standard specifies the numbering method for reference stations, waterlines, positions, transverse tanks, decks, tanks (cargo tanks, between-deck tanks, quilt tanks), hatches, coffins and cargo equipment required by computer programs in the field of shipbuilding. This standard is applicable to ordinary monohull merchant ships. Other types of tanks can also be used as a reference. Although this standard currently specifies the numbering method for the above-mentioned ship equipment and structural units, programmers can flexibly apply it according to specific circumstances and propose other specific numbering methods that are suitable for special circumstances. 2 station
Along the length of the ship, it can be equally divided into 10.20 or 1 design station intervals within the length of the vertical line. The design stations are numbered with decimal numbers, the ship's vertical is 0.0 station, the lying vertical is 10.0 station, 20.0 station or 100.0 station: the remaining design stations can be represented by decimal numbers with a decimal part of 0 (such as 5.0, 10.0 or 50.0). When an intermediate station is required between each design station, it can be numbered with a decimal number (such as 9.75, 19.50 or 07.5. The station number range can be extended beyond the vertical line, and the station number after the vertical line is a negative number. The station selection number mainly provides a reference method for identifying the station. It is best to make the number correspond to the actual position of the station according to the linear ratio relative to the vertical line. 3 Waterline
Waterline guides are identified by their height value (unit: m) from the baseline, and the spacing between each waterline depends on the needs. When the type value table is displayed with an infinite value, each waterline is represented by the ratio of its height to the design full-load waterline height in a decimal decimal. 4 Position
Position numbers are generally expressed as integers. The first position before the vertical line or the position with the same height as the vertical line is generally expressed as a decimal. The positions where the vertical loads overlap are numbered 0, and the remaining positions are numbered in sequence from vertical to horizontal. The positions in front of the vertical line are numbered positively, and the positions behind are numbered negatively. Transverse bulkheads, reinforcing frames and frames that do not extend throughout the entire cross section are to be included in the position numbering. In addition, the bulkheads are to be numbered in accordance with the requirements of Chapter 5.
5 Transverse bulkheads
Transverse bulkheads are numbered in integers, with the bulkhead closest to the top being numbered 1, and the remaining positions are numbered in sequence from vertical to horizontal. 6 Decks
The main deck is numbered Deck 1 (DECK1), and the decks below it are Deck 2 (DECK2), Deck 3 (DECK3), etc. Approved by China Shipbuilding Industry Corporation on March 20, 1998 and implemented on August 1, 1998
CB/T 3164-1998
For ships with double bottoms, the number of the lowest deck should be the number of the inner bottom or tank top plate. Decks that are not continuous within the entire length of the ship should also be assigned deck numbers if their length is equal to or greater than 50% of the length between perpendiculars. Discontinuous intermittent decks are considered to be the same deck if the change in deck height at the intermittent point is not greater than 30% of the height of the upper deck. Decks with a combined length less than 50% of the length between perpendiculars are not assigned deck numbers and can be individually identified using other numbering methods that comply with the design of the ship. Superstructure decks are also numbered sequentially with integers with a letter prefixed in front of the number. The letter S is generally used to represent the superstructure, and the letters P, B or F can also be used to represent the decks of the hip deck, bridge deck and collapse deck respectively. The first deck above the raw deck is designated as S1, and the rest are designated as S2 and S3 upwards. Etc., see Figure 1 for details.
7 Holds (cargo holds, deck tanks, liquid tanks)
The identification of a hold consists of the type code of the hold and the number code of the hold. The type codes of the hold are as follows: HOLD for cargo holds:
TANK for tanks:
TWDK for between-deck tanks.
The number of a hold is represented by a code of 4 segments with a maximum of 8 letters or numbers, such as: XX X XX×(XX)
Field 1: represented by integers 1 to 99, for example, the numbers of cargo holds, between-deck tanks, and liquid tanks are specified in 7.1 to 7.3 respectively. Field 2: represented by a single letter in the position of the hold on the ship. For example: C means in the middle of the ship; P means on the left side, and S means on the right side. Note: In a cross section, if there is only one type of hold (such as cargo hold, between-deck tank, pre-tank) and the hold is at the centerline of the hull, then Field 2 can be omitted.
Field 3: Use letters and numbers to provide further description. For example: UPR means above;
LWR means below;
IBD means inside;
OBD means outside;
FWD means front;
AFT means rear;
WNG means energy side
and 1, 2, 3.·Numbers, etc.
Note: When field 1 and field 2 can clearly describe the tank, field 3 can be omitted. Field 4: Use two letters to indicate the function or purpose of the tank. For example: RF indicates refrigerated tank;
FW indicates fresh water tank;
OF indicates fuel tank;
DT indicates deep tank; bZxz.net
BT indicates ballast tank;
OL indicates lubricating oil tank;
PO indicates dirty oil tank;
PW indicates sewage tank.
Note: Xueliang 4 can be marked as needed and can be omitted. Among them, BT, (OL, P), and PW are not listed in the international standard, which is added. When outputting text and graphics, empty fields should be omitted and not filled with spaces. The omitted fields should be deleted when outputting. Except for field 4, which is separated by a round insert, other fields are separated by a space. Example:
HOLD2 (DT) indicates the 2nd cargo hold (deep hold); 2
CB/T3164--1998
TANK15P (FW) indicates the 15th tank (fresh water tank) on the left; TWDK4LWR (RF) indicates the 4th lower deck tank (cold tank); TANK10S3 indicates the 10th tank on the right, 3rd row. Except for the field length and format, no specific regulations are made for the letters and alphanumeric strings used in fields 3 and 4. It is recommended that programmers use abbreviations related to the purpose and design structure of the tank. See Figure 1 for an example. 7.1 Cargo Holds
Cargo holds should be numbered in sequence from the ship's bottom, and the front cargo hold is numbered as Hold 1 (HOLDI). When the cargo holds are divided longitudinally, the sub-cargo holds are numbered opposite to each other in Section 1 and are distinguished by different characters in Field 3. When there are intermediate tanks, the order of the intermediate tanks shall be used as the basis for the numbering in field 1. As the structure of a specific ship may vary, no specific regulations are made on the identification method for distinguishing multiple wing tanks in field 3, but it is recommended that if numbers are used for distinction, the numerical numbering should be in the order from inside to outside and from ship to ship. 7.2 Between decks
The numbering method of between deck cargo holds shall be the same as the numbering method of the corresponding cargo holds in the school section. 7.3 Axilla
The numbering method of liquid tanks shall be the same as that of cargo holds, but a separate numbering sequence shall be used. For longitudinally extending side tanks that are not consistent with their inner tanks in longitudinal length, the numbering of the tank in field 1 shall be consistent with the numbering of the front inner tank that overlaps with it.
All tanks are numbered in the same order. Tanks of different purposes are distinguished by field 4. Deep tanks carrying dry cargo, liquid cargo or ballast water shall be regarded as cargo holds. The numbering format of
tanks also applies to hatches. For cargo hold openings, the numbering of field 1 shall be consistent with the corresponding cargo hold. 9 The numbering format of the gantry boom
compartment also applies to the gantry boom. Guns are numbered in order from the middle to the end. For guns located at the centerline of the ship, fields 2 and 3 may be omitted.
10 The numbering format of the cargo equipment
compartment also applies to the hoisting rod, cargo winch and deck crane. [0.1 The numbering of field 1 of the gantry boom shall be consistent with the numbering of the bracket connected to it. 10.2 Cargo winch
The numbering of field 1 of the cargo winch shall be consistent with the numbering of the stabiliser boom to which it is attached. 10.3 Deck hoists
Deck cranes are numbered in order from the end to the end. The foremost deck crane is numbered 1 in field 1. 3
