... Abstract On top of the abyssal plains of the Clarion-Clipperton Zone (CCZ) in the Pacific Ocean lie trillions of polymetallic nodules that contain many of the metals needed for transitioning to a low carbon future. In 2021, the pre-protype seafloor nodule collector ‘Patania II’ performed...

.... Calibrations performed to estimate these cone factors are typically done independently from each other and render constant values for each cone factor, which are independent of vertical effective stress and depth below seafloor. This leads to constant cone factors which may be incompatible within...

... Abstract Offshore energy development requires a thorough understanding of the seafloor and benthic environments to inform the potential risks to infrastructure and assess the potential environmental impacts of the project. In this paper, we present a novel method for generating quantitative...

... practices. This will result in reduced costs for the design of the floating structures and anchoring and mooring. These anchors can be installed in almost any seafloor condition, including hard rock, boulders, etc. and in severe weather conditions beyond those of current anchoring practices. Introduction...

... seafloor massive sulfides (SMS) with regards to minimizing footprint of the operation in all aspects. SMS reservoirs are mostly found in water depths between 2000m and 4000m. To explore these deposits in the deep sea a concept study based on a vertical trench cutting system has been developed. The extreme...

The fluid will be stored in a safe manner on the seafloor, protecting both personnel and marine life. The next step...

... Abstract Geophysical seismic surveys have been applied to marine geo-site characterization to create images of the complex geological conditions under the seafloor. Accurate knowledge of the ground conditions is critical for geo-risk assessment purposes such as mapping shallow gas hydrate...

... geohazards such as seafloor/buried faults, gumbos, gas hydrates, shallow gas and shallow water flow are routinely investigated using seismic reflectors, seismic amplitude, extent of well-known problematic stratigraphic units, and offset wells drilling data. As a result, the understanding of the regional...
