TDI-Brooks Completes Large Survey Campaign Off New York And New Jersey

The projects involved surveying in excess of 20,000 line-kms of analogue and either single or multi-channel seismic in lease blocks and cable routes along the coasts of New York and New Jersey. Various tasks were carried out at different stages, such as offshore geophysical surveys, UHRS detailed surveys, archaeological identification surveys, light geotechnical coring, and benthic sampling.

TDI-Brooks utilized three survey vessels, namely the R/V BROOKS McCALL, R/V MISS EMMA McCALL, and M/V MARCELLE BORDELON. The geotechnical survey involved over one-hundred and fifty (150) pneumatic vibracores (pVCs) and over one-hundred and fifty (150) Neptune 5K cone penetration tests (CPTs) gathered from both lease areas and along the offshore cable route (OCR). Along with multiple export cable route surveys, a reconnaissance survey covering the entirety of the lease area with 150-meter spaced survey lines was conducted, followed by a more detailed archaeological survey with 30-meter spaced lines. Survey sensors including dual head multibeam sonar, side scan sonar, sub bottom profiler, UHRS seismic, single-channel seismic, and Transverse Gradiometer (TVG) was utilized, all meeting BOEM specifications for archaeological surveys.
