Full title and description

ISO 15096:2020 — Ships and marine technology — Design and construction of cryogenic liquid tanker cargo containment systems for seagoing ships and barges: Requirements for design, construction, testing and inspection of cargo containment systems for the carriage of refrigerated liquefied gases (cryogenic liquids) in bulk.

Abstract

ISO 15096:2020 specifies principles, requirements and verification procedures for the design, manufacture, installation, testing and inspection of cargo containment systems used to carry refrigerated liquefied gases (cryogenic liquids) in bulk on seagoing ships and barges. The standard addresses structural design, materials, thermal insulation, secondary barriers, instrumentation and safety features to minimize risk of leakage, excessive boil‑off, structural failure or loss of containment during normal and specified abnormal conditions.

General information

Scope

This standard applies to cargo containment systems intended for the carriage of refrigerated liquefied gases (cryogenic liquids) in bulk on seagoing ships and barges. It covers the design, materials, construction, insulation, secondary containment arrangements, structural supports, testing, inspection and documentation necessary to ensure safe transport and to limit loss of containment and thermal hazards. It is intended to complement statutory and classification society requirements and does not replace national or international legislation.

Key topics and requirements

• Design principles for primary and secondary cargo containment systems suitable for cryogenic temperatures.
• Material selection and properties at low temperatures, including toughness and corrosion resistance.
• Thermal insulation requirements and design to control heat ingress and boil‑off rates.
• Structural strength and support arrangements to withstand sloshing, hydrostatic loads and ship motions.
• Leak detection, monitoring instrumentation and safe venting arrangements.
• Testing, non‑destructive examination and pressure testing procedures for new and repaired systems.
• Inspection regimes, maintenance and documentation requirements over the service life.
• Requirements for secondary barriers and drainage to minimize environmental and safety risks from leakage.

Typical use and users

Used by naval architects, ship designers, shipyards, classification societies, marine engineers, owners and operators of gas carriers and barges, equipment manufacturers (tanks, insulation, valves and instrumentation), surveyors and regulatory authorities. It supports the development and verification of cargo containment systems for liquefied gases such as LNG, refrigerated ethylene, liquefied natural gas or other cryogenic cargoes.

Related standards

Relevant standards and guidance typically used alongside ISO 15096:2020 include IMO/IGC and other maritime codes, classification society rules for gas carriers, ISO standards on cryogenic vessels and materials, and national regulations addressing the transport of liquefied gases. Related ISO documents may cover terminology, testing methods, instrumentation and material properties at low temperature.
