指南规范的第二版是为了吸收从1991年原始船舶碰撞指南规范的使用中吸取的经验教训而制定的；结合当前LRFD桥梁设计方法；阐明一些风险程序要素；进行小的修改和修正；并讨论并在必要时纳入自原始船舶碰撞出版物发布以来进行的驳船和船舶碰撞研究的结果。本修订版强调了使用指南规范程序评估现有桥梁，并提供了一个新的示例，说明了船舶碰撞风险评估程序。本版采用美国惯用单位编制。

This 2nd Edition of the Guide Specification was developed to incorporate lessons learned from the use of the original 1991 Vessel Collision Guide Specification; incorporate the current LRFD Bridge Design methodology; clarify some of the risk procedure elements; make minor modifications and corrections; and to discuss, and incorporate where deemed necessary, results from barge and ship collision research conducted since the original vessel collision publication. The use of the Guide Specification procedures to evaluate existing bridges has been highlighted in this revised edition, and a new worked example illustrating the vessel collision risk assessment procedures has been provided. This edition developed in U.S. Customary Units.
