Overview
ISO 22120:2026 - Ships and Marine Technology - Specification for Bunkering of Methanol Fuelled Vessels is the leading international standard for methanol bunkering in the maritime sector. Published by the International Organization for Standardization (ISO), this standard defines essential requirements to ensure the safe and reliable transfer of methanol as marine fuel. The document addresses transfer systems, operational procedures, risk assessment, safety protection, and personnel training for both international and domestic shipping operations. Its adoption supports industry-wide best practices and regulatory compliance for methanol bunkering equipment and procedures.
Key Topics
ISO 22120:2026 covers five critical elements to ensure safe and efficient methanol bunkering operations:
-
Transfer Systems
Covers specifications for hoses, pipes, pumps, valves, and loading arms used in methanol transfer. Includes requirements for compatible materials, pressure ratings, and emergency release systems.
-
Operational Procedures
Outlines procedures before, during, and after methanol bunkering, including assessments of compatibility, system connections, safety checks, vapour management, and documentation.
-
Risk Assessment
Guides on performing quantitative and qualitative risk assessments, establishing safety distances, hazardous area classification, and defining safety and security zones.
-
Safety Protection
Details protective measures such as personal protective equipment (PPE), fire and explosion protection protocols, anti-static controls, and requirements for fire monitoring and emergency procedures.
-
Personnel Training
Specifies training requirements for crew and personnel involved in methanol bunkering, ensuring competency in safety, emergency response, and handling procedures.
Applications
The ISO 22120:2026 standard is designed for a broad range of maritime stakeholders who are involved in the transfer and use of methanol fuel:
-
Ship Owners and Operators
Ensures safe onboard methanol handling during bunkering, safeguarding crew, vessel, and environment.
-
Port Authorities and Bunker Suppliers
Provides clear requirements for shore-based and mobile methanol transfer facilities, helping them meet both regulatory and operational standards.
-
Shipbuilders and Equipment Manufacturers
Offers technical guidance on manufacturing and installing compliant transfer systems, hoses, safety equipment, and related components.
-
Regulators and Inspectors
Establishes a framework for auditing methanol bunkering operations and verifying compliance with industry best practices and international regulations.
-
Crew Training Centers
Delivers guidance for developing comprehensive training programs focused on methanol handling and bunkering safety.
By using this standard, maritime organizations can ensure that methanol bunkering is conducted safely and efficiently, reducing potential risks of fire, environmental contamination, personnel injury, and asset loss.
Related Standards
Implementation of ISO 22120:2026 should be integrated with other relevant international standards and codes, including:
-
IEC 60079-10-1: Explosive atmospheres - Classification of areas - Explosive gas atmospheres
Essential for hazardous area classification during methanol transfer.
-
IEC 60092-502: Electrical installations in ships - Tankers
Defines requirements for electrical systems in tanker vessels involved in methanol bunkering.
-
IMO IGF Code: International Code of Safety for Ships Using Gases or Other Low-flashpoint Fuels
Mandates provisions for ships using low-flashpoint fuels, supporting the safety objectives of ISO 22120.
-
