  1. 1. Controlling the Roll Responses of PCTC's

    Författare :Carl-Johan Söder; Jakob Kuttenkeuler; Dominic Hudson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; PCTC; parametric roll; roll response; roll damping; rudder control; roll mitigation; racking;

    Sammanfattning : Modern Panamax Pure Car and Truck Carriers (PCTC) have become more vulnerable to critical roll responses as built in margins have been traded against increased transport efficiency. The research presented in this licentiate thesis aims at enhancing the predictability and control of these critical roll responses. LÄS MER

  3. 2. Controlling the Roll Responses of Volume Carriers

    Författare :Carl-Johan Söder; Anders Rosén; Jan De Kat; KTH; []
    Nyckelord :PCTC; parametric roll; roll response; roll damping; rudder control; aerodynamic roll damping; roll mitigation; racking; Ikeda’s method; CFD; model tests; Full-scale tests; Vehicle and Maritime Engineering; Farkostteknik;

    Sammanfattning : Modern volume carriers such as container vessels, cruise ships and Pure Car and Truck Carriers (PCTC’s) have become more vulnerable to critical roll responses as built in margins have been traded against increased transport efficiency. The research presented in this doctoral thesis aims at enhancing the predictability and control of these critical roll responses. LÄS MER

  4. 3. Development of speed-power performance models for ship voyage optimization

    Författare :Xiao Lang; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; full-scale measurements; speed-power performance; added resistance due to waves; energy efficiency; machine learning; voyage optimization;

    Sammanfattning : Various measures, such as voyage optimization, performance monitoring and ship cleaning schedules, have been developed to help increase the energy efficiency of shipping operations. One of the most important elements needed for these measures is a reliable ship speed-power model. LÄS MER
