Not long ago, a member’s vessel was detained at load port because the density of the solid bulk cargo being loaded exceeded the maximum allowable cargo density for that particular vessel. Recently, we were also approached by another member because the master of a capsize bulk carrier had refused charterer’s request for alternative hold loading due to serious concern about the ship’s safety.
The above instances appear to have come about due to a lack of knowledge of the CSR-BC Class Notations.
What are the CSR-BC Class Notations? CSR-BC means the Common Structural Rules for Bulk Carriers which were adopted by the International Association of Classification Societies (IACS) in December 2005 and came into effect on 1 April 2006. CSR-BC Class notations are assigned to bulk carriers of 150 meters or above in length based on the service features of dry bulk cargo densities and cargo hold loading patterns. There are three primary class notations for CSR bulk carrier: BC-A, BC-B and BC-C. These are stated on a vessel’s class certificate and loading manual.

散货船安全：注意船舶结构限制
不久前，一船舶因为装载的固体散货密度超过该船舶的最大允许货物密度，而在装货港遭到滞留。最近，一艘好望角型散货船的船长以严重威胁船舶安全为由，拒绝执行租船人提出的隔舱装货请求。
上述两起事件，都与对CSR-BC船级附加标志缺乏了解相关。
什么是CSR-BC船级附加标志？CSR-BC是指国际船级社协会(IACS)于2005年12月通过并于2006年4月1日生效的《散货船共同结构规范》。CSR-BC船级附加标志授予船长150米或以上的散货船，具体按照干散货密度和货舱装载模式的服务特点确定。CSR散货船有三种主要的船级附加标志：BC-A、BC-B和BC-C。这些标志在船舶的船级证书和装载手册上均有注明。
