Additionally, advanced plate bending was achieved using Line Heating Technology, ensuring precise and effective construction. This comprehensive approach resulted in a more capable and efficient vessel ready for demanding offshore operations.

 

  • CFD Analysis of an Offshore Supply Vessel for Duct Installation
    • Vedam conducted a comprehensive CFD analysis for a client, focusing on the installation of a nozzle over the CPP (Controllable Pitch Propellers) of their Offshore Supply Vessel. The scope included performing Self-Propulsion CFD analysis both with and without the propeller nozzle to optimize propulsion characteristics. The objectives were to increase bollard pull thrust, ensure uniform water flow to the propeller, reduce cavitation, and decrease loading on the propellers. This analysis aimed to enhance the vessel’s overall propulsion efficiency and performance in demanding offshore conditions.
