Compliance overview
Scope and applicability
This standard is mandatory and applies to the safety operations of oil tankers within all ports situated in China's jurisdictional waters. It comprehensively covers general safety requirements, loading and unloading operations, and other related procedures such as inerting and tank cleaning. It is essential for shipowners, terminal operators, and maritime safety compliance engineers managing oil tankers in Chinese ports. The standard specifically targets vessels carrying bulk liquid oil cargoes, excluding petrochemicals.
Technical requirements
The standard outlines comprehensive safety protocols across several operational phases. For general safety, it mandates strict hydrological and meteorological assessments before operations and requires continuous, reliable communication channels between the ship and shore. Operations must cease immediately if communication fails without an effective backup. It also sets rigorous fire and explosion prevention measures, including designated smoking areas, restrictions on naked lights, and the mandatory use of explosion-proof electrical equipment in dangerous zones. Regarding cargo transfer, the standard specifies requirements for loading and unloading operations, including the critical verification of initial and maximum transfer rates. It enforces the use of a closed operational method for gauging and venting to minimize vapor release. Ship and shore personnel must jointly agree on and confirm transfer rates, pressure limits, and emergency shutdown procedures prior to commencement. The standard also details specific safety checks for pre-berthing, mooring, and departure. For other related operations, the standard sets parameters for inerting operations, requiring oxygen content in cargo tanks to be maintained below a specific threshold with a positive pressure. It also references GB 41730 for tank cleaning and GB 16993 for enclosed space entry. Thermal work is strictly prohibited during cargo, ballast, or inerting operations. Additionally, it mandates the use of insulating flanges or non-conductive hoses to prevent stray currents.
Testing methods
Compliance verification primarily involves the mandatory completion of the Ship/Shore Safety Checklist (Annex A) before and during cargo transfer. This checklist serves as the primary evaluation tool, requiring verification of mooring arrangements, communication systems, emergency readiness, and electrical insulation. Both ship and terminal representatives must physically check and sign this checklist. Additionally, the standard requires regular testing of gas detection systems, oxygen analyzers, high-level alarms, and emergency shutdown devices to ensure operational integrity.
