    • Alternative manoeuvres to reduce ship scour 

      Castells Sanabra, Marcel·la; Mujal Colilles, Anna; Llull Marroig, Antoni Ignaci; Moncunill Marimon, Jorge; Gironella Cobos, Xavier; Martínez de Osés, Francesc Xavier (Cambridge University Press, 2020-08-03)
      Article
      Open Access
      Scouring and sedimentation effects on the seabed induced by ship propellers during ship manoeuvring near harbour structures affect both structure stability and ship manoeuvring capabilities. This contribution proposes ...
    • Anàlisi del port de Palma com a port comercial

    • Composite methodology to prevent ship propeller erosion 

      Llull Marroig, Antoni Ignaci; Mujal Colilles, Anna; Castells Sanabra, Marcel·la; Gironella Cobos, Xavier (2020-01)
      Article
      Restricted access - publisher's policy
      The jet flow generated by manoeuvring ships nearby vertical structures is known to erode the seabed sediment but is still difficult to predict the effects of a particular ship operating in a harbour basin. This paper ...
    • Hybrid tool to prevent ship propeller erosion 

      Llull Marroig, Antoni Ignaci; Mujal Colilles, Anna; Castells Sanabra, Marcel·la; Gironella Cobos, Xavier; Martínez de Osés, Francesc Xavier; Martín Mallofré, Agustí; Sánchez-Arcilla Conejo, Agustín (American Society of Mechanical Engineers (ASME), 2018)
      Conference report
      Open Access
      The present contribution aims to implement a new methodology to prevent Roll on-Roll off vessels (RO-RO) from causing severe scouring actions. The methodology combines field, experimental, theoretical and numerical tools ...
    • Manoeuvre analysis and simulation to prevent seabed scour due to ship propellers 

      Mujal Colilles, Anna; Castells Sanabra, Marcel·la; Gironella Cobos, Xavier; Llull Marroig, Antoni Ignaci (Universitat Politècnica de Catalunya. Departament de Ciència i Enginyeria Nàutiques, 2020-09)
      Conference report
      Open Access
      Erosion of the seabed is produced by cargo and passenger vessels when manoeuvring in a harbour basin due to the high-speed jet flow generated by the main propellers. In case of twin propeller vessels, the ability to perform ...
    • Ship manoeuvre analysis and simulation to obtain scouring related propeller variables 

      Llull Marroig, Antoni Ignaci; Mujal Colilles, Anna; Gironella Cobos, Xavier; Castells Sanabra, Marcel·la; Martínez de Osés, Francesc Xavier; Martín Mallofré, Agustí; Sánchez-Arcilla Conejo, Agustín (International Centre for Numerical Methods in Engineering (CIMNE), 2018)
      Conference lecture
      Open Access
      The evolution of shipping industry in terms of bigger and more powerful ships, is causing several issues in existing ports and marinas designed, initially, to host smaller vessels with smaller propulsion systems and lower ...
    • Ship manoeuvre patterns to prevent propeller scouring effects 

      Castells Sanabra, Marcel·la; Mujal Colilles, Anna; Llull Marroig, Antoni Ignaci; Gironella Cobos, Xavier; Martínez de Osés, Francesc Xavier; Martín Mallofré, Agustí; Sánchez-Arcilla Conejo, Agustín (World Association for Waterborne Transport Infrastructure (PIANC), 2018)

    • Ship manoeuvring effects on propeller induced erosion 

      Mujal Colilles, Anna; Llull Marroig, Antoni Ignaci; Castells Sanabra, Marcel·la; Gironella Cobos, Xavier; Martínez de Osés, Francesc Xavier; Sánchez-Arcilla Conejo, Agustín (2018)
      Conference report
      Restricted access - publisher's policy
      The shipping industry evolution over the last decades has led to growing structural and operational problems, in particular, for old marinas with lower depths to hosts present ships and with higher drafts and power of ...
    • Ship propeller effects on harbours 

      Llull Marroig, Antoni Ignaci; Mujal Colilles, Anna; Castells Sanabra, Marcel·la; Gironella Cobos, Xavier (Texas Digital Library, 2020)
      Conference report
      Open Access
      The increase in marine traffic during the last decades has led to important changes in ship designs. These changes have been directly affecting harbor structures designed to host smaller and less powerful ships. One of the ...
    • Stern twin-propeller effects on harbor infrastructures. Experimental analysis 

      Mujal Colilles, Anna; Castells Sanabra, Marcel·la; Llull Marroig, Antoni Ignaci; Gironella Cobos, Xavier; Martínez de Osés, Francesc Xavier (2018-11-02)
      Article
      Open Access
      The growth of marine traffic in harbors, and the subsequent increase in vessel and propulsion system sizes, produces three linked problems at the harbor basin area: (i) higher erosion rates damaging docking structures; ...
