Offshore survey player carried out the site survey work off its owned and operated research vessel the R/V Proteus.

The goal was to assess seabed conditions prior to the emplacement of a drilling rig at three proposed locations together with reconnaissance survey work at two additional platforms and along a number of proposed cable/pipeline routes.

TDI-Brooks survey objectives included:

Debris Clearance Survey (DCS) at each of the locations;

Identification as well as areal nature establishment of the previous spud can footprints;

Establishment of the nature of the shallow soils; within the top 5 metres and to a depth of approximately 20 – 25 metres;

Acquisition of deep CPT data 20 metres at two locations;

Acquisition of representative data at nominal proposed Relief Well Locations (RWL);

Reconnaissance of existing platforms and along proposed routes (single lines).

In addition to a site survey, TDI-Brooks completed gCPT measurements at two proposed drill sites.

Specifically, the purpose of the TDI-Brooks Gravity CPT (gCPT) tool is to transport a precisely calibrated memory cone penetrometer down to the seabed to gather dynamic PCPT cone data from the mud line to 10+ m BML.

In addition to its 800 kilograms driving head with lifting bale and trigger, the rig comprises a self contained PCPT cone penetrometer that measures tip resistance (qc), sleeve friction (fs), and pore pressure (u2) using standard ASTM dimensions and protocols for its 15-cm2 cone.
