Foreword

GB/T 21481 "Ships and marine technology on ships and marine structures - domestic water supply" is divided into two parts.

--- Part 1. Planning and design;

--- Part 2. Calculation Method.

This section GB/T 21481 Part 1, identical with ISO 15748-1:2002 "Ships and marine technology ships and marine knot the structures for domestic water supply - Part 1. Planning and Design "(in English).

For ease of use, this section made the following editorial changes.

--- "This International Standard" be replaced by "this section";

"." --- With a decimal point instead of a comma as the decimal point, "";
