Full title and description

ISO 4127-2:1980 — Shipbuilding — Inland vessels — Fairleads — Part 2: Roller fairleads. Specifies types, basic parameters and technical requirements for roller fairleads used on inland navigation vessels.

Abstract

Part 2 of ISO 4127 defines the classification, nominal sizes, principal dimensions and basic technical requirements for roller-type fairleads for inland vessels. The original international edition was published in 1980 and the document has since been withdrawn from the ISO catalogue.

General information

• Status: Withdrawn (International Standard withdrawn from ISO catalogue).
• Publication date: June 1980 (edition 1, 1980-06).
• Publisher: International Organization for Standardization (ISO).
• ICS / categories: 47.060 — Inland navigation vessels.
• Edition / version: Edition 1 (1979/1980 series — Part 2 published 1980).
• Number of pages: 3 pages (short technical specification).

Scope

The standard applies to roller fairleads intended for use on inland vessels and specifies types, dimensional parameters and essential technical requirements to ensure safe and consistent mooring and line-guiding performance on river and canal craft. It does not cover sea-going ship fairleads or other types covered in Part 1 (two‑lip fairleads).

Key topics and requirements

• Classification of roller fairleads by type and function (nominal types used for inland navigation).
• Principal dimensions and nominal sizes for rollers and bodies to ensure interchangeability and predictable performance.
• Basic material and construction requirements appropriate to inland-vessel service conditions.
• Requirements for mounting, securing and basic load-related properties to support mooring operations.
• Short normative references to related shipbuilding standards (e.g., wire rope characteristics) where applicable.

Typical use and users

Manufacturers of deck hardware and fairleads, shipyards building or repairing inland navigation vessels, classification societies, port and mooring equipment suppliers, and design offices involved in inland-ship outfitting use this standard (or its national adoptions) as a dimensional and technical reference.

Related standards

ISO 4127 is a multi‑part series — Part 1 (Two-lip fairleads, ISO 4127-1:1979) is directly related. National adoptions and translations exist: for Russia a national adoption exists as GOST R ISO 4127-2-2005 (ГОСТ Р ИСО 4127-2-2005), and in some countries the ISO parts were adopted under local standards catalogues (for example cross-references to DSTU listings).

FAQ

Q: What is this standard?

A: ISO 4127-2:1980 is the Part 2 specification in the ISO 4127 series covering roller fairleads for inland vessels — a brief technical specification of types, dimensions and basic requirements.

Q: What does it cover?

A: It covers roller-type fairleads used on inland navigation vessels: classifications, principal dimensions, nominal sizes and the basic technical and constructional requirements necessary for safe mooring and line guidance.

Q: Who typically uses it?

A: Shipbuilders, deck‑gear manufacturers, suppliers of mooring equipment, classification societies and vessel outfitters working on inland (river/canal) vessels. National standards bodies and technical libraries also reference it when preparing local adoptions.

Q: Is it current or superseded?

A: The ISO edition (ISO 4127-2:1980) is listed as withdrawn in the ISO catalogue. Some national adoptions (for example GOST R ISO 4127-2-2005) have been issued to provide a Russian-language national version of the content; users should check the current status of any national adoption before relying on it for regulatory or procurement decisions.

Q: Is it part of a series?

A: Yes — ISO 4127 is a series for fairleads on inland vessels; Part 1 covers two‑lip fairleads (ISO 4127-1:1979) and Part 2 covers roller fairleads (ISO 4127-2:1980).

Q: What are the key keywords?

A: Fairlead, roller fairlead, inland vessels, shipbuilding, mooring equipment, ISO 4127, GOST R ISO 4127-2-2005.
