van der Ree, Chris (author)There is a growing demand of various metals originating from the sustainable energy transition. The current supply and investments plans for these critical minerals are insufficient to enable this green energy transition. Other problems are the dependency of third countries and multiple drawbacks of land-mining. Deep-sea mining could be a great...master thesis 2024

Meijssen, Ries (author)The shift to sustainable energy sources has increased demand for Energy Transition Metals such as nickel, copper, cobalt, and manganese. To satisfy this need while reducing the negative social and environmental effects of conventional mining, Deep-sea Nodule Collection (DSNC) appears to be a feasible option. Despite its potential, DSNC...master thesis 2024

Alhaddad, S.M.S. (author), Elerian, M.F.A.I. (author)Turbidity currents have extensively been explored in quiescent environments. However, during several underwater activities (e.g., dredging and deep sea mining), generated turbidity currents could travel in opposite directions and interact with each other, which could largely influence their hydrodynamics and sediment transport capacity....journal article 2024

de Hoog, E. (author), van der Voort, Tjalie (author), Talmon, A.M. (author), van Rhee, C. (author)Hydraulic transport pipelines in the dredging, mining and deep sea mining are designed using steady-state methods. However, these methods cannot predict density wave formation. Density waves form a risk for pipeline blockages, therefore there is a need to understand and preferably be able to model the process. The density waves studied in...journal article 2024

Alhaddad, S.M.S. (author), Suleman, M. (author), Kirichek, Alex (author), Chassagne, C. (author)Coandă-effect-based collection stands out as the foremost technology in polymetallic-nodule mining due to the absence of direct contact between the collector and the ocean floor. Yet, this collection method disturbs the ocean floor, and minimizing such disturbance is crucial from an environmental viewpoint. To this end, a solid understanding of...journal article 2024

Liu, Xiangwei (author), Yang, Shuhao (author), Pang, Y. (author)Deep-sea mining activities have lately attracted growing interest. Recent research has led to the development of a hydraulic–mechanical hybrid vertical lifting system for deep-sea mining. Predicting the resistance of vertical plug flow in this system is critical for its engineering design. In this paper, an analytical model was developed to...journal article 2024

Elerian, M.F.A.I. (author)The depletion of terrestrial mineral deposits and the increasing demand for minerals are causing disruptions in the global supply chain. The shift towards renewable technologies requires significant quantities of metals used, for example, in the production of electric vehicles and wind turbines, putting additional strain on the supply chain. The...doctoral thesis 2023

Alhaddad, S.M.S. (author), Mehta, D. (author), Helmons, R.L.J. (author)We present an effective design of a hydraulic, polymetallic nodule collector, which fundamentally depends on the Coandă effect in harvesting nodules. The design was first developed based on 2D numerical simulations conducted using a computational fluid dynamics tool, ANSYS FLUENT. Following that, the design was tested in full-scale experiments,...journal article 2023

Alhaddad, S.M.S. (author), Helmons, R.L.J. (author)To date, hydraulic collection is the most widely considered technology in polymetallic-nodule mining, since there is no direct contact between hydraulic collectors and ocean floor. To construct a hydraulic collector that results in the least sediment disturbance, it is critical to develop an insightful understanding of the interaction between...journal article 2023

Elerian, M.F.A.I. (author), Huang, Ziyang (author), van Rhee, C. (author), Helmons, R.L.J. (author)We have developed and investigated a hydrodynamic model of Deep-Sea Mining (DSM) collector turbidity flows that captures sediment particle aggregation and breakup. Flocculation is expected to have a significant impact on determining the spread patterns of the turbidity flows and the resulting turbidity currents. The recently validated drift...journal article 2023

Ali, W. (author), Enthoven, D.H.B. (author), Kirichek, Alex (author), Helmons, R.L.J. (author), Chassagne, C. (author)For green energy transition, the industry seeks alternative resources for nickel and cobalt, the main ingredients for energy storage devices and other applications. Polymetallic nodules lying at the abyssal plain are rich in these mineral resources, which leads to an increased interest in deep-sea mining (DSM) of polymetallic nodules. During the...conference paper 2022

These nodules are rich in commercially precious metals, such as nickel, cobalt and copper, making them a target for potential future deep-sea exploitation. Generally, polymetallic nodules are partially buried in the seabed...conference paper 2022
