SSS has a reputation for completing highly complex projects requiring extremely difficult mobilizations. The project examples below highlight our capabilities:
Vibracoring, Salem, Oregon
Work Scope:
SSS mobilized personnel and equipment to collect samples in a landlocked agricultural pond. SSS mobilized floating platforms and sampling gear into the pond with a 50 ton hydraulic crane. Even with challenging bottom conditions (clay and gravel liner that had to be repaired post-collection) the work was performed on time and under budget. The work site including the crane pad was restored to original condition by NUC workers.
# of Samples:
8
Vessel:
24' aluminum sampling platform
Water Depth:
20'
Sample Depth:
15'
Vibracoring, Impact Core, Surface Grab Sampling, Strait of Juan de Fuca
Work Scope:
SSS mobilized personnel and equipment to collect samples in an open water near coastal area. SSS successfully collected samples during high wind and cross current conditions. Three-point anchoring was utilized to insure the vessel stayed on position while samples were taken. A custom buoyancy package was used to collect deepwater cores up to 225'. Other services included ultrashort baseline acoustic positioning of the vibracore head, assisted environmental
engineering firm with decon and processing.
Vessel:
45' Aluminum research vessel with knuckleboom
Water Depth:
15' to 225'
Sample Depth:
Up to 22'
Vibracoring, Portland, Oregon
Work Scope:
SSS mobilized personnel and equipment to a very shallow and narrow location along the Columbia River Slough. This project required personnel to navigate our custom pontoon barge, equipped with a collapsible 25' a-frame, under low bridges (44” clearance) and through shallow water to reach the sampling location. Samples were processed on site.
Vessel:
25' Pontoon work vessel with 25' a-frame and moonpool
Water Depth:
2' to 8'
Sample Depth:
8'
Power Grab Sampling, Hanford Nuclear Reservation, Washington
Work Scope:
SSS mobilized personnel and custom equipment for bottom grab sampling of 130 samples along a 150 mile stretch of the Columbia River using a pneumatically assisted “clam shell” style sampler. Current up to 8 knots and water depths as shallow as 1 foot with 20 knot winds and sub-zero wind chill were just a few of the challenges for this job. Using a combination of DGPS and navigation software SSS operators stayed on position live boating. Live boating
was the safest and most efficient means to stay on position and collect samples. All processing was performed on the vessel. The job was completed on time and stayed on budget. Interaction with multiple federal and tribal agencies was required during this project.
