Ships and marine technology - Marine environment protection - Oil booms - Part 3: End connectors

This document specifies the requirements for the design of end connectors of oil booms used for the prevention of spreading of oil spills on water. These criteria are intended to define minimum mating characteristics and are not intended to be restricted to a specific configuration. It should be considered that different types of connectors are preferably used in different areas. This document does not define any priority. It remains the responsibility of manufacturers and users to select the right connector for the intended application. Stability features of boom connectors are the result of interaction between bodies of booms and connectors. This document does not purport to address all safety concerns, if any, associated with its use. However, it is the responsibility of the user of this document to establish the appropriate safety and health procedures, and to determine the applicability of regulatory limitations.

Overview - ISO 17325-3:2018 (Oil booms - End connectors)

ISO 17325-3:2018 specifies minimum design requirements for end connectors used on oil booms for marine environment protection. It defines mating characteristics and generic configurations (not a single prescriptive design) and addresses mechanical strength, sealing, stability and usability of connector types used to prevent oil spread on water. The standard emphasizes manufacturer and user responsibility for selecting appropriate connectors and establishing safety procedures.

Key topics and technical requirements

• Design characteristics: connectors shall provide adequate mechanical strength; minimize oil leakage; present no handedness (neither male nor female); maintain full boom height; not impair stability or reduce freeboard; and require no special tools for assembly.
• Desirable features: quick/easy connection in water, lightweight, debris immunity, and ease of installation or replacement.
• Connector types covered: zip connector, Z‑connector, slide connector, hinge connector, U‑bolt connector, and eyelet/loop/lace connectors - each with guidance on application limits and force transmission.
• Locking pins and positioning: locking pins (used in Z and slide connectors) must fit bore precisely to prevent loosening, be corrosion‑resistant and require minimal tools. Pin-hole positioning is referenced to the design waterline (DWL): for connectors < 609.6 mm a secondary hole at 152.4 mm ± 0.038 mm below DWL; for connectors ≥ 609.6 mm multiple holes spaced 304.8 mm ± 0.038 mm. Corner radii minimum 1.52 mm to reduce handler injury.
• Materials: corrosion‑resistant materials with sufficient mechanical strength; avoid galvanic corrosion when different alloys are used.
• Testing and records: tests and documentation follow ISO 17325‑2 (strength and performance requirements).

Practical applications and users

Who uses ISO 17325-3:2018:

• Oil boom designers and manufacturers selecting or developing end connectors
• Marine contractors and oil spill response teams selecting boom systems
• Procurement officers and port authorities specifying boom performance
• Regulatory bodies and maritime safety authorities assessing conformity

Practical use cases:

• Specifying connector type for containment, towing or storage (e.g., U‑bolts for long‑term, zip or slide for quick assembly)
• Ensuring connector design directs towing forces into boom tension members
• Selecting corrosion‑resistant materials and correct locking pin dimensions for field use
• Creating procurement specifications and maintenance records for oil spill response equipment

Related standards

• ISO 17325-2 (Strength and performance requirements)
• ISO 16165 (Terminology for oil spill response)
• ASTM F962, F2438, F1093 and F1523 (reference standards for connector types, tests and selection guidance)
• JIS F9900 (Japanese specification for booms and connectors)

Note: ISO 17325-3:2018 provides design minima and guidance; users remain responsible for safety procedures and regulatory applicability when deploying oil booms and connectors.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/directives).

Introduction
This document specifies the design of end connectors of oil booms. It has been developed after
considering the existing ASTM standards and national legislative requirements, and discussions
with individuals involved in the development of these standards. This document incorporates and
acknowledges the use of and refers to many of the elements provided in ASTM F962 and F2438.
This document gives some general guidelines for oil boom manufacturers as well as users with regard
to subjects dealing with producing and purchasing such types of equipment. This document does not
define any specific type and size of connector for a particular application, as so many variables have to
be taken into consideration.
The American Society for Testing and Materials (ASTM) Committee F-20 has published two standards
relating to boom connectors (ASTM F962 and F2438). ASTM F1093 specifies static laboratory tests of
the strength of an oil spill response boom under tensile loading. ASTM F1523 provides a guide on the
selection of a containment boom that may be used to control spills of oil and other substances that float
on the water.
The Japanese Industrial Standard JIS F9900 (Parts 1 and 2) provides the necessary conditions and
specifications for the design, manufacture, and other aspects of oil booms and connectors.
It is the responsibility of the user of this document to establish appropriate safety and health practices
prior to use.
