PARTIALLY PENETRATING WAVE BARRIERS
Partially Penetrating Wave Barriers Partially Penetrating Wave Barrier Schematic Blane Harbor, WA - Wave Barrier Vertical wave barrier that stops short of the seafloor. Typically applicable in moderate (5 to 10 ) wave environments Advantages: Reduced cost Reduced footprint Allows circulation and fish passage below barrier Can be combined with dock structures
Partially Penetrating Wave Barriers Skagway Harbor Skagway, AK With the wave barrier now in place we are able to protect our existing facility as well as all of the vessels the facility accommodates. The 5 wave action originally allowed through the entrance of the harbor has been reduced to barely a ripple Matt O Boyle Harbormaster 300 wave primary barrier with access trestle/promenade and 80 stem wall Designed for 5 significant wave height and transmitted wave height of less than 2 Construction Cost = $3.5MM
Partially Penetrating Wave Barriers Cape Disappointment Ilwaco, WA 250 wave barrier Designed to transmit < 1.0 wave under 50 year storm event Cantilever pipe piles with sheet pile wings
Partially Penetrating Wave Barriers Bell Street Pier, Seattle, WA Port of Astoria, OR - West Basin Breakwater
SPIN FIN PILES
SPIN FIN Pile Tips SPIN FIN piles are bearing piles that increase both compression and tensile capacity. Modified end bearing anchored with angled fins. Allows for pile installation in limited overburden, reduced pile lengths and within soft soils. Improved load-deformation characteristics
SPIN FIN Pile Testing
SPIN FIN Piles Construction Methods Driven using conventional impact and vibratory hammers, templates, and accessories. Driven in same manner as Non-SPIN FIN piles.

OPEN CELL DOCKS AND BULKHEADS
OPEN CELL Structural Stability OPEN CELL Patents: 6,715,964 B2 7,018,141 B2 7,488,140 B2 Patent Application No: 12/879,997 Comprised of vertically driven, interlocked flatweb sheet piles. Arc-shaped face acts as a horizontally tied tension membrane Face and tailwall sheets connect at a wye pile. Straight tailwalls serve as anchors. Similar to Mechanically Stabilized Embankment (MSE) and Closed Cellular Structures.
OPEN CELL System Components PND designs the OPEN CELL system using flat sheet pile and extruded connectors.
Design Flexibility Low sensitivity to scour Easy modifications Minimal embedment required Stable in large seismic events High load capacity Allows high wall heights Accommodates soft soil or shallow bedrock Fast-tracked design Speed/Ease of construction Decreased construction costs Cost savings Umm Qasr Pier, Umm Qasr Iraq
