CFD STUDIES

Ventilation system performance improvement procedure, regarding additional reefer containers carriage.

• 3D laser scanning and 3D modelling of each cargo hold of the containership.
• CFD analyses for calculating temperature distribution and air flow velocity inside the cargo hold for the new operating condition (additional reefer containers), utilizing the existing ventilation capacity.
• Hot spots check.
• Additional ventilation capacity evaluation.
• Required ventilation capacity calculation according to Class rules.
• Identification of ventilation ducts proper placement.
• Modified duct arrangement design.
• Selection of appropriate fans.
• Preparation of technical documentation / drawings (e.g. revised duct arrangement, structural drawings, electrical drawings).

Overhauling / upgrading ventilation system for improved performance.

• Attendance / supervision of installation / repair of existing ducting systems.
• Attendance / supervision of fan installation / verification of proper operation.
• Assessment of the new ventilation condition of the vessel by detailed measurements of duct mass flow rates and temperature distribution within the cargo holds.
