Ship and offshore technical protective coatings and inspection methods
Part 1. Dedicated seawater ballast tanks
1 Scope
GB/T 34430 provisions of this part of the ship dedicated seawater ballast tank coating protection and inspection methods.
This section applies to all types of ships not less than 500 gross tonnage seawater ballast tanks and bulk carriers not less than 150m in length double side
Side premises, and is a construction contract signed on or after July 1,.2008, or without a construction contract but laid on or after January 1,.2009
Keel or similar construction phase, or in July 1,.2012 and after delivery of the ship.
This section also applies to the construction contract signed on or after December 8,.2006, the length of not less than 150m double hull structure tanker
Dedicated seawater ballast tanks and bulkheads of not less than 90 m in length having double side skin spaces.
Note. Double side skin means a longitudinal bulkhead and side shell connected to the double bottom and deck by the side of the vessel. If possible, the hopper tank and topside tank may form double-sided
The complete part of the structure of the side. Therefore, a bulk carrier, empty tank or other designated tank with a single-side structure designed as part of a topside tank shall not be considered as a double
Side shelter (shown in Figure 1 and Figure 2).
Description.
1 --- topside cabin;
2 --- hopper tank;
3 --- Empty space or other designated space (not to be regarded as double side skin).
