Assessment of expected production of a deep-sea mining system: An integrated model-based systems engineering and discrete event simulation approach
Solheim, Astrid Vamråk; Rauzy, Antoine Bertrand; Brett, Per Olaf; Ellefmo, Steinar Løve; Hatling, Tonje; Helmons, Rudolfus Lambertus Jacobus; Asbjørnslett, Bjørn Egil (Peer reviewed; Journal article, 2023)In this paper, model-based systems engineering (MBSE) and discrete event simulation (DES) are combined to assess the performance of an offshore production system at an early stage. Various systems engineering tools are ... -
Dispersion of Benthic Plumes in Deep-Sea Mining: What Lessons Can Be Learned From Dredging?
Helmons, Rudolfus Lambertus Jacobus; de Wit, Lynyrd; de Stigter, Henko; Spearman, Jeremy (Journal article; Peer reviewed, 2022) -
Effect of flocculation on turbidity currents
Ali, W.; Enthoven, D.; Kirichek, A.; Chassagne, C.; Helmons, Rudolfus Lambertus Jacobus (Peer reviewed; Journal article, 2022)Flocculation between inorganic sediment, salt ions and microscopic organic matter present in the marine environment might play an important role in the dynamics of turbidity currents. The ability to predict, understand, ... -
Experimental and Numerical Modelling of Deep-Sea-Mining-Generated Turbidity Currents
Elerian, Mohamed; van Rhee, Cees; Helmons, Rudolfus Lambertus Jacobus (Journal article; Peer reviewed, 2022) -
The Influence of Particle Size on Sliding Wear of a Convex Pattern Surface
Yan, Yunpeng; Helmons, Rudolfus Lambertus Jacobus; Schott, Dingena (Peer reviewed; Journal article, 2022)Sliding wear of bulk handling equipment (e.g., shovel bucket, mill and transfer chute) can be dramatically reduced by using a convex pattern surface compared to a flat surface, by adjusting the flow behavior of particles ... -

Mining of deep-seabed nodules using a Coandă-effect-based collector
Alhaddad, Said; Mehta, Dhruv; Helmons, Rudolfus Lambertus Jacobus (Peer reviewed; Journal article, 2023)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 ... -
Pin-on-Disc Modelling with Mesh Deformation Using Discrete Element Method
Yan, Yunpeng; Helmons, Rudolfus Lambertus Jacobus; Schott, Dingena (Peer reviewed; Journal article, 2022)The pin-on-disc test is a standard sliding wear test used to analyse sliding properties, including wear contour and wear volume. In this study, long-term laboratory test performance is compared with a short-term numerical ...
