On June 28, 2012, the tugboat Sea Cap VII capsized upstream of the New West Rail Bridge in the Fraser River. The tugboat was assisting another tugboat when the incident occurred. Thankfully no crew members were badly injured.
As a result of the incident, Port Metro Vancouver contracted Public Works and Government Services Canada (PWGSC) to conduct a multibeam survey of the area surrounding where the vessel was last sighted. The multibeam data was processed in CARIS HIPS and SIPS and was used to help locate the vessel and determine its position.
