Full title and description

St ISO 15749-5:2004 — Ships and marine technology — Drainage systems on ships and marine structures — Part 5: Drainage of decks, cargo spaces and swimming pools. This part addresses the planning and design of gravity-operated drain lines to convey grey water from weather decks and non-weathertight spaces (including ro-ro decks, cargo spaces and swimming pools) on ships and marine structures.

Abstract

ISO 15749-5:2004 specifies principles for designing drain lines for gravity drainage of grey water from exposed decks and non-weathertight spaces on ships and marine structures. It focuses on hydraulic conveyance, routing, sizing and arrangement of drains for decks, ro-ro and cargo spaces and swimming pools, and indicates the relationship to other parts of the ISO 15749 series for sanitary and blackwater systems.

General information

• Status: Published — International Standard (confirmed in periodic review, most recently confirmed in 2024).
• Publication date: 2004-05 (Edition 1, 2004).
• Publisher: International Organization for Standardization (ISO).
• ICS / categories: 47.020.30 (Piping systems / Ships and marine technology).
• Edition / version: Edition 1 (2004).
• Number of pages: ISO lists 7 pages for the ISO-published version; national/adopted versions (EN/BS/DIN/… adaptations) may show different page counts depending on national front matter.

Scope

Applies to planning and design of drain lines for gravity-operated conveyance of grey water from weather decks and non-weathertight spaces on ships and marine structures, including ro-ro decks, cargo spaces and shipboard swimming pools. It does not cover blackwater (sewage) disposal, which is addressed in other parts of ISO 15749. The part gives design guidance for routing, capacities and interfacing with the shipboard sanitary/drainage arrangement.

Key topics and requirements

• Design principles for gravity-operated deck and space drainage systems (sizing and hydraulic capacity).
• Routing and arrangement of drains and drain lines on weather decks, ro-ro decks and cargo spaces.
• Special considerations for swimming-pool drainage on ships (overflow and emergency draining).
• Definition and handling of grey water vs. blackwater; reference to other ISO 15749 parts for sanitary and sewage systems.
• Interface and coordination requirements with overall ship sanitary and drainage-system design (see ISO 15749-1 for general design principles).

Typical use and users

Primary users include naval architects, marine and piping engineers, ship designers, shipyards, equipment suppliers, classification societies, maritime regulatory bodies and consultants involved in shipboard drainage and sanitary system design. The standard is used when specifying or reviewing drainage layouts and capacities for newbuildings, conversions and retrofits.

Related standards

ISO 15749-5 is part of the ISO 15749 series on drainage systems for ships and marine structures. Closely related parts include ISO 15749-1 (sanitary drainage-system design) and ISO 15749-2 (sanitary drainage, drain piping for gravity systems); other parts of the series address blackwater and additional topics. National/adopted versions exist as EN/BS/DIN/ÖNORM etc.

FAQ

Q: What is this standard?

A: ISO 15749-5:2004 is an international standard that provides guidance for the planning and design of gravity-operated drain lines to convey grey water from decks, cargo spaces and swimming pools on ships and marine structures.

Q: What does it cover?

A: It covers hydraulic and layout considerations for deck and non-weathertight-space drainage (sizing, routing, interfaces with sanitary systems) specifically for grey water; it does not set out provisions for blackwater/sewage disposal (see other parts of ISO 15749).

Q: Who typically uses it?

A: Naval architects, marine engineers, shipyards, equipment suppliers, classification societies and maritime regulators use this standard when designing or reviewing shipboard drainage arrangements.

Q: Is it current or superseded?

A: The ISO bibliographic record shows ISO 15749-5:2004 as published in 2004 and last confirmed during ISO’s systematic review process (confirmed in 2024), so this edition remains current as of the most recent ISO confirmation. Users should check with their national standards body or ISO for the very latest status before procurement or compliance work.

Q: Is it part of a series?

A: Yes — it is Part 5 of the ISO 15749 series (drainage systems on ships and marine structures). Related parts (for example ISO 15749-1 and ISO 15749-2) cover general sanitary drainage-system design and gravity drain piping for sanitary systems.

Q: What are the key keywords?

A: Ship drainage, deck drains, grey water, gravity drainage, cargo-space drainage, ro-ro deck drainage, swim-pool drainage, sanitary drainage design, ISO 15749.
