Hull war risk is an independent insurance separated from hull insurance, which posses some characteristics of hull insurance, the principles of the hull insurance therefore apply to it. On the other hand, the fact that the hull war risk become an independent insurance illustrates that it has some special natures such as the risks it covers are exclusive, the premiums categorize general and special one, the Notice of Termination Clause is so distinguished that not covered by the hull insurance. However, PICC hull war risk insurance is an additional insurance to its hull insurance, which is improper as an independent risk.

船舶战争险是从船壳险中分离出来的独立风险，它具有与船壳险相同的特征，保险法的基本原则同样适用于战争险；另一方面，船舶战争险能够成为独立的风险，说明它具有不同于船壳险的特征，它承保的风险具有专属性，它的保费分为一般保费和特殊保费，它的通知终止条款是船壳险所没有的……但是，中国人保船舶战争险却是船壳险的附加保险，与战争险作为独立风险的性质不相适应。
