Full title and description

St ISO 15749-2:2004 — Ships and marine technology — Drainage systems on ships and marine structures — Part 2: Sanitary drainage, drain piping for gravity systems. This part of ISO 15749 covers the design and basic technical requirements for sanitary drain lines that rely on gravity (gravity drainage) on ships and marine structures.

Abstract

ISO 15749-2:2004 specifies requirements and guidance for sanitary drainage piping laid out as gravity systems aboard ships and marine structures. It is intended to be used with ISO 15749-1 (planning and basic requirements) and complements other parts of the ISO 15749 series addressing drainage systems on ships and marine structures.

Scope

Specifies the design principles and requirements for sanitary drain lines operating by gravity on ships and marine structures. The standard addresses selection and arrangement of piping, functional requirements for gravity drainage of sanitary fixtures and associated piping, and interfaces to planning guidance given in ISO 15749-1. It applies to new designs and installations where gravity sanitary drainage is used aboard vessels and offshore/marine installations.

Key topics and requirements

• Design criteria for sanitary drain lines in gravity systems (pipe sizing, slope/gradient, venting considerations).
• Selection and arrangement of drain piping and fittings suitable for marine environments.
• Functional requirements for satisfactory gravity drainage of sanitary fixtures and collectors.
• Interface and coordination with planning and basic requirements in ISO 15749-1.
• Considerations for installation, routing and access consistent with shipboard safety and maintenance.

Typical use and users

Used by ship designers, naval architects, marine engineers, shipyards, classification societies, and project teams responsible for the piping and sanitary systems on new ships, conversions and marine structures. Also referenced by regulatory and certification authorities, equipment suppliers and consultants working on shipboard sanitation and drainage layouts.

Related standards

ISO 15749-1 (Ships and marine technology — Drainage systems — Part 1: Sanitary drainage-system design) — provides planning and basic requirements and should be used together with Part 2. Other parts of the ISO 15749 series (for example Parts addressing sewage disposal and other drainage types) and complementary standards for piping materials, marine installations and identification of piping contents are often used in conjunction.

FAQ

Q: What is this standard?

A: ISO 15749-2:2004 is an international standard that specifies requirements for sanitary drain piping designed as gravity systems on ships and marine structures.

Q: What does it cover?

A: It covers the design, selection and arrangement of sanitary drain lines that operate by gravity, including functional requirements for drainage of sanitary fixtures and connections to planning guidance in ISO 15749-1.

Q: Who typically uses it?

A: Ship designers, naval architects, marine engineers, shipyards, classification societies, suppliers of sanitary piping systems, and consultants involved in shipboard plumbing and drainage projects.

Q: Is it current or superseded?

A: The 2004 edition (ISO 15749-2:2004, Edition 1) remains a published international standard and was confirmed through ISO’s systematic review process (confirmation recorded in 2024). Users should check with their national standards body or ISO for any later amendments or reconfirmations before application.

Q: Is it part of a series?

A: Yes — ISO 15749 is a multipart standard on drainage systems for ships and marine structures; Part 1 covers planning and basic requirements and other parts address additional drainage and sewage disposal topics. ISO 15749-2 is explicitly linked to Part 1 for planning and basic requirements.

Q: What are the key keywords?

A: Ship drainage, sanitary drainage, gravity systems, drain piping, marine piping systems, ISO 15749, shipboard sanitation.
