While the review of the IMO Circular 645 – Guidelines for vessels with Dynamic Positioning systems – is expected to be reviewed in 2017 bringing important key elements in the design and operation of DP vessel (see our article dated on 9 Sep 2015), we continue on promulgating DP concepts and DP awareness to all our Customers and Followers. In this article we focus on the main non conformities to be avoided in the management of DP documentation. The following table gives some bad-habits to be avoided:
