Orcas Island ferry terminal

Typical ferry terminal structures (enlarge)

This project replaced a timber pile dolphin with a new steel pipe pile dolphin. A dolphin is a structure located in the water used as a landing aid for the ferries as they approach the terminal. The new steel pipe pile dolphin is the final component in the replacement of the landing aids at the Orcas ferry terminal. Two old concrete dolphins were previously replaced at Orcas in fall 2008.

How You Benefit
Cross GlyphImproves Safety
The replacement of this dolphin protects the adjacent marina and prevent the ferries from grounding in shallow water. It also protects the ferry dock structure from damage in the event that a vessel were to lose power, lose control of the steering system or be caught in weather that would cause the vessel to come off line during a landing.
Leaf Glyph Protects Environment
WSF has been removing creosote-treated wood from Puget Sound for years based on regulatory permit requirements. This wood is then properly disposed of rather than being reused.
