TDI-Brooks' latest dynamic positioning (DP) vessel, the RV NAUTILUS, has reached the shores of the East Coast of the United States. The DP2 vessel RV NAUTILUS from TDI-Brooks, with a length of 75 meters and built in 2000, arrived at the US East Coast on March 3, 2024. After undergoing a 6-month retrofit in Las Palmas, the vessel will provide support for offshore wind projects and various other subsea needs. It is equipped with advanced technology, including a Geomil Manta-200 CPT that can be deployed through the mid-ship moonpool of NAUTILUS. This system can penetrate the soil up to 40-50 meters, depending on its composition, to determine the soil's exact makeup. This data is crucial for identifying the best location and design for offshore developments like wind farms. The offshore renewable energy sector is expanding rapidly, resulting in a high demand for TDI's services on both the US East and West Coasts.

TDI-Brooks remains dedicated to the expanding offshore wind sector in addition to various scientific survey initiatives. Despite the robust demand for subsea services and the increasing needs of clients, the company is well-equipped to provide a wide range of offshore support services, including subsea operations, construction assistance, exploration, and production support, ROV and diving services, as well as scientific marine research and survey mapping, and even military assistance.

The NAUTILUS is a versatile vessel with (1) North American MCK-1240 upper forecastle deck STBD side SWL 7.1-ton crane, large accommodation (46 berths) and deck capacity. The vessel is outfitted with TDI-Brooks’ complete geotechnical tool kit including a suite of innovative geotechnical tools for soil sampling and measurement. These include 0.5- and 1-meter box corers (BC), 6- and 9-meter piston corers (PC), 20-meter jumbo piston corers (JPC), cyclic t-bar instrument (TBAR), piezocone penetrometers including a 40-meter CPT-Stinger and 10 meter Gravity CPT tool (gCPT), newly acquired Geomil Manta-200 CPT, Neptune 3K & 5K vibracorers and TDI-Brooks’ designed pneumatic vibracorer. The Nautilus also has a Teledyne RESON full ocean depth multibeam echosounder (MBES) for performing hydrographic marine, surface geochemical “seep-hunting” (SGE) and seabed heatflow surveys (HF).

TDI’s mission is to “safely deliver high-quality oceanographic services, including acquisition, sampling, analysis and scientific interpretation, to the marine environmental, geochemical, geotechnical and survey marketplace.”
