《GB/T 36213-2018船舶与海上技术 船舶系泊和拖带设备 系泊导缆孔》由TC129（全国船舶舾装标准化技术委员会）归口，主管部门为国家标准化管理委员会。
Introduction
GB/T 36213-2018/ISO 13713:2012 Standard Overview
GB/T 36213-2018 is a Chinese national standard equivalent to the international standard ISO 13713:2012, which mainly regulates the design, dimensions and technical requirements of mooring fairleads in ship mooring and towing equipment. This standard is applicable to all types of ships and their related offshore facilities.
Core Content Interpretation
1. Background of Standard Formulation
With the development of the global shipping industry, the safety and reliability of ships have become key areas of concern. As key components in ship operations, the performance of mooring and towing equipment directly affects navigation safety and operating efficiency. The formulation of GB/T 36213-2018 aims to unify domestic standards and ensure the high performance and safety of ship mooring and towing equipment.
2. Analysis of technological evolution
This standard inherits ISO 13713:2012 in terms of technology, and has been localized in accordance with the actual needs of China's shipbuilding industry. By introducing finite element model analysis and modern material science, the strength assessment method of the fairlead hole has been improved.
3. Comparison of standard frameworks
| Dimensions | ISO 13713:2012 | GB/T 36213-2018 |
|---|---|---|
| Scope of application | Global ship and offshore technology field | Chinese shipbuilding and shipping industry |
| Technical requirements | Unified international standard requirements | Adjusted in combination with domestic actual needs |
| Update cycle | Regular revision to maintain technological advancement | Synchronize with international standards and update in a timely manner |
4. Implementation Suggestions
(1) Design and Selection
- Size Selection:Select the nominal size (such as 250X200, 300X250, etc.) reasonably according to the ship type and mooring and towing requirements.
- Material Requirements:Preferably use cast steel or equivalent materials that meet the standards, and ensure that the weld leg length meets the calculated weight requirements.
(2) Installation and Maintenance
- Installation Location:Select a suitable location according to the mooring fairlead hole type (Type A deck installation, Type B navigation wall installation) to ensure structural stability.
- Marking Requirements:Clearly mark the safe working load (SWL) in accordance with IMO guidelines and classification society requirements to avoid obstruction.
(3) Inspection and Compliance
- Material Inspection:Mechanical property test of steel castings to ensure the yield strength is not less than 235 N/mm².
- Structural Inspection:Inspect the welding quality of the base to ensure there are no cracks or pores and meet the requirements of mooring and towing load.
