26 Proceedings Winter 2015–2016 www.uscg.mil/proceedings Considered a marine casualty, such incidents must always be reported to Coast Guard personnel, who will follow up on the report and determine the appropriate level of inves- tigative effort necessary based on various factors, such as: • property damage value, • extent of personal injuries, • resulting damage to the environment. Intended Groundings The second type, an intended grounding, is considered as such when it's a controlled, deliberate maneuver to place the vessel or barge in contact with the riverbed. Among other reasons, one might choose to attempt an intended ground- ing to offoad passengers, hold position to adjust cargo, or hold position to allow safe navigation and passage of other traffc in the area. Because these groundings are designated "intentional," they're not required to be reported unless the vessel can't free herself as intended or the intentional grounding causes damage to any people, property, or the environment. In any of those circumstances, the casualty must be reported to the Coast Guard using USCG form 2692. The Coast Guard would then evaluate the report to determine the appropriate level of investigative effort, as they would with an unin- tended grounding. Bump and Go The fnal type of grounding is commonly known as the "bump and go," where the involved vessel master or licensed mate on watch attests that: • the grounding (including grounded barges under the control of a towing vessel) was only momentary (e.g., reversing engines freed the grounded vessel on the frst attempt); • no assist vessel was needed to free the vessel and all towing connections remained intact; Grounding incidents occurring on the U.S. western rivers can differ greatly from typical groundings due to the unique factors of these waterways. 1 There are three basic types of groundings, explained in depth below. Unintended Groundings The first such type of incident is called an unintended grounding. This involves any situation in which the vessel is inadvertently or accidentally brought into contact with or placed on the ground, or riverbed. When Things Go Bump Western rivers groundings. by MR.
