Full title and description

ISO/TS 16901:2022 — Guidance on performing risk assessment in the design of onshore LNG installations including the ship/shore interface. This technical specification gives a common, risk-based approach to identifying and assessing major safety hazards during the planning, design and operation of onshore liquefied natural gas (LNG) facilities and shoreline interfaces with ships; environmental consequences of an LNG release are excluded from scope.

Abstract

This Technical Specification (edition 2, 2022) provides guidance and a decision-support framework for safety risk management specific to onshore LNG terminals and related facilities (including satellite and peak-shaving plants). It addresses hazards inside the terminal perimeter and hazards at the ship/shore link, recognises but does not treat ship navigation and intrinsic tanker operation risks, and references general risk-assessment standards such as IEC 31010 and ISO 17776.

Scope

The standard applies to the assessment of major safety hazards in the design of onshore LNG installations and the ship/shore interface. It is intended for export and import terminals and may be applied to satellite and peak-shaving facilities. It covers hazardous materials handled within the terminal (LNG, LPG, pressurised natural gas, odorisers and other flammable or hazardous products) but does not set acceptable risk levels or address environmental impacts or intrinsic tanker navigation risks. The ship/shore link is identified as the interface where port operation and terminal responsibilities meet.

Key topics and requirements

• Decision-support framework for safety risk management tailored to LNG facilities.
• Guidance on performing risk assessments during planning, design and operation phases.
• Identification and assessment of major safety hazards within terminal perimeters and at ship/shore interfaces.
• Application to export/import terminals, satellite and peak-shaving plants; coverage of LNG and associated hazardous products.
• Exclusion of environmental consequence assessment for LNG releases and of intrinsic tanker navigation risks; references to relevant maritime codes (IGC/IGF) for vessel design assumptions.
• Cross-references to general risk assessment methods and standards (for example IEC 31010 and ISO 17776) and to other normative references used in the LNG sector.

Typical use and users

This Technical Specification is used by process safety and risk engineers, terminal designers, project managers, operating companies, safety specialists, consultants, port authorities and regulators involved in LNG terminal design and shore-to-ship interface projects. It supports risk assessments during concept, detailed design and early operation stages and is used to inform safety management and design decisions.

Related standards

Commonly referenced documents and codes include IEC 31010 (risk management — risk assessment techniques), ISO 17776 (general offshore risk assessment guidance), the IGC and IGF Codes for LNG/IGF-fuelled vessels, and other ISO/TC 67 publications relevant to petroleum and natural gas industries; the previous edition ISO/TS 16901:2015 was withdrawn and replaced by the 2022 edition.

A: ISO/TS 16901:2022 is a technical specification that provides guidance for performing safety risk assessments in the design and operation of onshore LNG installations and at the ship/shore interface.

Q: What does it cover?

A: It covers methods and a decision-support framework for identifying and assessing major safety hazards in LNG terminals (including satellite and peak‑shaving plants) and hazards arising at the ship/shore link; it excludes environmental consequence assessment and intrinsic tanker navigation risks.

Q: Who typically uses it?

A: Users include LNG terminal designers, process safety and risk engineers, operators, consultants, project managers and regulators concerned with terminal and shore-to-ship interface safety.

Q: Is it current or superseded?
