3. 2. Modeling of planing craft in waves

   Författare :Karl Garme; Dan Zenkert; Richard Akers; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hydraulic engineering; marine; ocean; Planing craft; time-domain simulation; design loads; Vattenteknik; Water engineering; Vattenteknik;

   Sammanfattning : Simulation of the planing hull in waves has been addressed during the last 25 years and basically been approached by strip methods. This work follows that tradition and describes a time-domain strip model for simulation of the planing hull in waves. The actual fluid mechanical problem is simplified through the strip approach.

   Författare :Harsha Cheemakurthy; Karl Garme; Joakim Kalantari; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; waterborne public transportation; commuter ferry; modular design; operational requirements; ranking method; sustainable performance; ice operations; ice-hull Interaction; ice load; ice properties; kollektivtrafik på vatten; modulärt färjekoncept; modulär design; rankningsmetod; hållbarhetsparametrar; isbelastning; isförhållanden; isegenskaper; Vehicle and Maritime Engineering; Farkostteknik;

   Sammanfattning : There has been a recent surge in interest in waterborne public transportation (WPT). Publictransport providers (PTP) are seeing its potential in complementing the existing transportnetwork and alleviating urban traffic congestion and pollution. But the adoption of WPTtoday is challenging due to a series of technical and implementation challenges. LÄS MER

   Sammanfattning : Waterborne public transportation (WPT) is slowly increasing in importance as an active component of public transportation networks in cities. City planners are looking at WPT to overcome urban congestion and pollution. LÄS MER

7. 5. Towards consonance in working conditions, health and performance aboard high-performance marine craft

   Författare :Manudul Pahansen de Alwis; Karl Garme; Anders Rosén; Stephen Myers; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; high-speed craft; human factors; whole-body vibration; epidemiology; pain; fatigue; höghastighetsfartyg; mänskliga faktorn; helkroppsvibrationer; epidemiologi; smärta; trötthet; Vehicle and Maritime Engineering; Farkostteknik;

   Sammanfattning : The High-Performance Marine Craft (HPMC) is a complex man-machine system dealing with the stochastic nature of the sea. The occupants of these craft are challenged by the strenuous work environments resulting in various detrimental conditions and reducing the overall performance of the system. LÄS MER
