Full title and description

STB BS ISO 23575-2022 — Ships and marine technology — Marine securing devices for ro-ro cargoes. This standard specifies types, dimensions and strength characteristics of devices used for securing roll-on/roll-off (ro-ro) cargoes in sea transportation and provides requirements and guidance for selection, testing, marking and installation of fixed and portable securing fittings used on ro-ro decks (also applicable as a reference for road vehicles secured on inland vessels).

Abstract

ISO 23575:2022 defines classes and dimensional tables for marine securing devices for ro-ro cargoes, sets load-rating requirements (MSL/PL/MBL), prescribes minimum testing and inspection procedures (type and production tests), and gives marking, material and installation guidance. The document is intended to ensure consistent, safe and auditable securing arrangements on ro-ro vessels and vehicle stowage areas.

Scope

This standard specifies the types, classification, key dimensions and strength characteristics (e.g., maximum securing load — MSL, proof loads and minimum breaking loads) of marine securing devices intended for the stowage and securing of ro-ro cargoes on board ships. It covers fixed and portable fittings, dimensional tolerances, material and fabrication considerations, requirements for type and production testing, marking and documentation, and provides informative guidance on layout, installation and maintenance. The scope also notes applicability as a reference for securing road vehicles on inland vessels.

Key topics and requirements

• Classification and terminology for fixed and portable securing fittings used on ro-ro decks.
• Dimensional tables for common fitting types and size designations (specific tables for DR, LC, CL, CB, LS types and similar).
• Strength ratings: specification of MSL, proof-test loads and minimum breaking loads (MBL) and typical MSL bands (examples include 40 kN, 75 kN, 100 kN, 160 kN, 180 kN depending on device type and size).
• Requirements for type testing (sample selection and procedures) and production testing to ensure consistent manufacturing quality and conformity.
• Material, welding and fabrication guidance including dimensional tolerances and corrosion/low-temperature performance considerations.
• Marking, traceability and documentation requirements for manufacturer identification, rated loads and test records.
• Layout and spacing guidance for fixed fittings on ro-ro lanes (example guidance: longitudinal and transverse spacing limits and minimum MSL for lane fittings) and recommendations for avoiding sharp edges or obstructions in vehicle runways.
• Installation, inspection and maintenance recommendations and guidance for inclusion in ship cargo securing manuals.

Typical use and users

ISO 23575:2022 is used to specify and procure compliant securing devices, to test and certify fittings, and to support shipboard securing arrangements and cargo securing manuals. Typical users include shipowners and operators of ro-ro and vehicle carriers, shipbuilders and naval architects, manufacturers of lashing and securing equipment, classification societies and marine surveyors, port authorities, cargo securing officers and deck crews, and insurers and regulatory bodies involved in cargo securing safety and audits.

Related standards

Closely related documents and references commonly used alongside ISO 23575 include: ISO 23577 (vocabulary for cargo securing systems), ISO 3874 (container handling and securing), and other ISO and industry standards dealing with welding, tolerances and corrosion protection. IMO cargo securing guidance and a vessel’s cargo securing manual are also used in combination with this standard when planning and auditing ro-ro stowage.

FAQ

Q: What is this standard?

A: ISO 23575:2022 (adopted as BS ISO 23575:2022) is an international standard that specifies types, dimensions and strength characteristics of marine securing devices used to secure ro-ro cargoes on ships. It defines load ratings, test requirements, marking and installation guidance for fixed and portable fittings.

Q: What does it cover?

A: It covers classification of securing device types, dimensional tables, MSL/proof/MBL requirements, type and production testing, material and fabrication considerations, marking and documentation, and practical guidance for layout, installation and maintenance of fittings used on ro-ro decks. It is also applicable as a reference for securing road vehicles on inland vessels.

Q: Who typically uses it?

A: Shipowners and operators of ro-ro vessels, shipbuilders, naval architects, manufacturers of lashing and securing equipment, classification societies, port authorities, marine surveyors, cargo securing officers, deck crews and insurers use the standard to specify, test, install and audit securing devices and stowage arrangements.

Q: Is it current or superseded?

A: ISO 23575 was published in 2022 (ISO edition March 2022; national adoption BS ISO 23575:2022 published April 6, 2022). As of 23 February 2026 this standard is published and in force. Users should check the issuing body (ISO or their national standards body, e.g. BSI for the BS edition) for any amendments, corrigenda or a newer revision after that date.

Q: Is it part of a series?

A: The standard sits within a family of cargo-securing publications (vocabulary and related standards). Relevant complementary documents include ISO 23577 (cargo securing systems vocabulary) and other ISO/IMO guidance on cargo securing; it aligns with broader cargo-securing practice rather than being a multi-part series itself.

Q: What are the key keywords?

A: Key keywords are ro-ro, marine securing device, lashing point, MSL (maximum securing load), proof test, minimum breaking load, fixed fitting, portable fitting, cargo securing, BS ISO 23575:2022.
