GB/T 34430.3-2017Ships and marine technology -- Protective coatings and inspection method -- Part 3: Cargo oil tanks of crude oil tankers (English PDF)

Foreword

GB/T 34430 "marine and marine protective coatings and inspection methods" is divided into five parts.

--- Part 1. Dedicated seawater ballast tanks;

--- Part 2. Empty bulk carriers and tanker;

--- Part 3. Crude oil tanker;

--- Part 4. Automatic measurement of water-soluble salts;

--- Part 5. Assessment of coating damage.

This section GB/T 34430 Part 3.

This section drafted in accordance with GB/T 1.1-2009 given rules.

This section uses the translation method identical with ISO 16145-3:2012 "Ship and marine protection coatings and inspection methods Part 3 Points. Crude cargo tank. " the documents of our country that are consistent with the corresponding international documents that are normative references in this section are as follows.
