在imo的体系中，标准的定义如下：
"Void space" is the enclosed space in the cargo area external to a cargo containment system, not being a hold space, ballast space, fuel oil tank, cargo pump or compressor room, or any space in normal use by personnel.
"Cofferdam" is the isolating space between two adjacent steel bulkheads or decks. This space may be a void space or ballast space.
多个规范中引用这一定义，例如：Res. A.328(9)
而在某些特别的规范中有更具体的定义，如：MSC/Circ.1120
2 June 2004
UNIFIED INTERPRETATIONS OF SOLAS CHAPTER II-2, THE FSS CODE, THE FTP CODE AND RELATED FIRE TEST PROCEDURES
Regulation 4.5.1
Construction of "cofferdams" and prohibition of containment of cargo, wastes and goods
The expression "cofferdam" means, for the purpose of this regulation, an isolating space between two adjacent steel bulkhead or decks. The minimum distance between the two bulkheads or decks should be sufficient for safe access and inspection. In order to meet the single failure principle, in the particular case when a corner-to-corner situation occurs, this principle may be met by welding a diagonal plate across the corner (see figure of regulation 4.5.1 in the appendix). No cargo, wastes or other goods should be contained in cofferdams.
至于测深管/吸口、透气管/透气帽是否配备，请不要单从两者的定义来区分。这不是决定测深管/吸口、透气管/透气帽的依据。
要不要测深管/吸口，取决于是否有水或别的东西，如果可能性很大，就要配备。
要不要透气管/透气帽，取决于是否密闭，如果密闭就应该要。
是不是密闭，则主要取决于安全性，例如现在流行的燃油舱保护空仓就要求密闭，泵舱双层底以前是开式，现在规范要求密闭以防止破损进水，等等 |
