(WO) — TDI-Brooks has accomplished a geophysical and geotechnical survey for a marine cable route in Alaska’s Valdez Arm, deploying its Gravity CPT Stinger (gCPT) system on behalf of Woolpert.
The challenge used the gCPT system to gather in-situ soil knowledge alongside the proposed cable route. Designed for deployment in distant offshore environments, the system transports a piezocone penetrometer (PCPT) to the seabed and may accumulate knowledge from the mudline to depths of 5 m and, underneath appropriate situations, greater than 10 m beneath the mudline.
Piezocone testing gives steady measurements of tip resistance, sleeve friction and pore stress, permitting soil power and stratigraphy to be evaluated in actual time with out typical drilling.
For marine cable set up, the ensuing knowledge can be utilized to evaluate soil variability alongside the route, decide burial and trenching situations and establish potential geohazards that would have an effect on set up.
TDI-Brooks mentioned the transportable system is designed to help offshore web site investigations in distant and logistically difficult environments comparable to Alaska.
The corporate gives seabed investigation providers for offshore power, telecommunications and infrastructure tasks worldwide.
