Ferry Service Impacts and Schedule Adjustments

We work with the U.S. Coast Guard to schedule vessel dry-docking that meets safety and licensing requirements and minimizes impacts to our customers. We sometimes have to assign a smaller vessel on some routes to allow larger vessels to go in for maintenance and repairs.

You can download the following document for detailed information about vessel maintenance, dry dock, and inspection needs projections, along with anticipated service impacts.

Please note that these service scenarios are subject to change at any time based on dry dock availability and emerging maintenance and repair needs. To see the location of in-service ferries in real time, please visit our VesselWatch page.

Emergency Service Plans

Washington State Ferries Vessel Maintenance and Preservation

Washington State Ferries completes more than 99 percent of its trips. This is the actual number of scheduled trips that are completed, not including weather or tidal cancelations; and includes those trips that WSF is able to complete by replacing one vessel with another.

The Life Cycle Cost Model

To keep our service so dependable, WSF's Vessels Department plans vessel maintenance and preservation work years in advance. This advanced scheduling system helps us stay ahead of problems and is one reason for WSF's high trip completion rate.

The Life Cycle Cost Model (LCCM) involves scheduling equipment and parts for preservation according to their useful lifespan, and the potential impact on service should they fail.

Every piece of equipment on the vessel has its own defined life cycle, which is closely tracked and scheduled in advance to either be replaced or preserved according to each part's life cycle schedule. By doing this in conjunction with regular vessel inspections and annual maintenance, the ferry system can allocate its resources in a way that makes sense for the entire system and keeps our operation running smoothly.
