RR220 - Ship collision and capacity of brace members of fixed steel offshore platforms

Supply boat collision is one of the most critical accidents that can affect structural safety and integrity of fixed installations. In the splash zone the most likely impact scenarios are: broadside impact of one of the legs of the platform; and, bow or stern impact of one of the braces in the splash zone. This report deals with aspects related to the bow or stern vessel collision with one of the braces in the splash zone. In the industry there is a difference of opinion on how well these splash zone braces are able to resist vessel impact.
