TDI-Brooks Adds to Africa Project List with Nigerian Survey
working in Nigeria until the third quarter of this year on various analogue and 2D HR survey projects.TDI-Brooks is presently operating three vessels in West and Southwest Africa, engaged in various projects for leading international oil companies. The company’s 75-meter DP-II vessel, R/V Nautilus, is currently involved in a deepwater geotechnical project off the coast of Namibia, which includes 20-meter JPCs and 40-meter CPT-Stingers.Following this, the company will undertake a shallow water deep push CPT project with its Manta-200. These projects are expected to conclude by early March
Ocean Exploration taps Leeway Marine to Manage Ship
The Ocean Exploration Trust (OET) has selected LeeWay Marine to step into the vital role of vessel manager.LeeWay will be responsible for crewing the vessel and overseeing the technical support and operational planning required to complete the critical missions scheduled for their Exploration Vessel Nautilus (E/V Nautilus).Established by American oceanographer Dr. Robert Ballard, best known for discovering “black smoker” hydrothermal vents and the final resting place of R.M.S. Titanic, OET makes ocean exploration possible, providing hands-on and remote learning opportunities for scientists
UK Approves Five Subsea Power Cable Projects
into both British and European grids, and are both planned by National Grid.The LionLink project, co-owned by Dutch grid operator Tennet, will connect Dutch offshore wind farms to both the Dutch and the British grids and provide up to 1.8 GW of low-carbon electricity to each country.In the same way, the Nautilus project, co-owned with Belgian grid operator Elia, will connect Belgian offshore wind and provide up to 1.4 GW of capacity to each country.The new projects are all expected to be complete and operational by the end of 2032, Ofgem said.National Grid's participation in the OHA projects is conditional
TDI-Brooks Concludes Geotechnical Campaign Off Turkey
TDI-Brooks, a U.S.-based marine services company specializing in geotechnical and offshore survey projects, has completed its fifth geotechnical investigation for DenAr Ocean Engineering in Black SeaThe RV NAUTILUS was dispatched to the Black Sea from the US East Coast to facilitate this operation. The geotechnical aspect of the investigation included 49 gCPTs, 50 JPCs, 48 CPTs, and 41 BCs.Additionally, an environmental component was incorporated, which comprised 27 Environmental BCs, 28 CTDs, 19 water samples, and 180 kilometers of marine fauna transects.TDI-Brooks provides a comprehensive range of
All Set for Cable Installation at US' First Utility-Scale Wave Energy Test Site
, were transported via freighter to Louisiana and transferred to Offshore Support Vessel (OSV) HOS Innovator, which will be used to lay the cables, to make their way to Oregon.Nexans' Cables for US' First Grid-connected Wave Energy Test FacilityOnce the work begins, a second vessel, the OSV Nautilus, will follow behind to bury the cable using a remotely operated vehicle (ROV). Those two vessels are expected to work around the clock for the duration of the installation and their lights may be visible at night when they are close to shore, Hellin said.A third vessel, the M/V Liberty, will support

TDI-Brooks' Retrofitted Vessel Arrives to US for Offshore Wind Work
TDI-Brooks' latest dynamic positioning vessel, the RV Nautilus, has reached the shores of the East Coast of the United States ahead of work for offshore wind sector.After undergoing a six-month retrofit in Las Palmas, the 2000-built vessel will be put to work to provide support for offshore wind projects and various other subsea needs.With the length of 75-meters, the DP2 vessel is equipped with advanced technology, including a Geomil Manta-200 CPT that can be deployed through the mid-ship moonpool.The system can penetrate the soil up to 40-50 meters, depending on its composition, to determine the
TDI-Brooks' New Vessel Ready for Work
TDI-Brooks' newest vessel R/V Nautilus (formerly known as Nautical Geo) is ready to go to work following a 6-month retrofit period in Las Palmas.The DP2 vessel is currently enroute to the U.S. East Coast to provide support for offshore wind operations. It is expected to be fully prepared for the first offshore wind program by early March.Built in 2000, the 75-meter-long vessel is equipped with the newly-acquired Geomiil Manta-200 CPT, which can be deployed through the mid-ship moonpool. The system has the capability to penetrate the soil up to 40-50 meters, depending on its composition.Nautilus
