UNDER UNUSUAL CONDITIONS
INITIAL SETUP:
Materials:
Teflon Tape
Reference:
Refer to this TM, WP 0007 Set-Up - Operation Under Usual Conditions
Personnel Required
Three Operator/Crew
Equipment Condition
TWPS skid removed from transport vehicle and set on level ground.
Loose items unpacked (off-loaded) from the TWPS skid and placed in their general operational position.
GENERAL
The OISS is used for water intake from sandy beach locations when surf conditions or tide extremes
make it difficult or impossible to use the floating inlet strainer. This work package contains the
procedures to set up the OISS (Ocean Intake Structure System). The procedures covered in this work
package include:
Planning
Establishing a Water Source to Jet the Wellpoints
Jetting the First Wellpoint
Jetting the Second Wellpoint
Jetting the Third Wellpoint
Jetting the Fourth Wellpoint
Checking for Hydrogen Sulfide
PLANNING
Assess the tidal and surf conditions to determine the best location for the OISS using the following
guidelines:
When there is a large horizontal tidal variation and/or water surface conditions are rough, install
the OISS above the high tide position with two 5 ft. risers attached to each of the four wellpoints.
When water surface conditions are calm or if hydrogen sulfide or iron is known to be present in
the groundwater, install the OISS at a low tide position with 2 ft. risers attached to each of the four
wellpoints.
The best time to install the OISS is at low tide when the wellpoints can be installed at an optimum
configuration.
