Scope of work
- Express audit:
- Study of hydrodynamic improvements applicable to the vessel
- Statistical prediction of the impact of improvements
- Economic return on investment
- 3D model of the hull
- Hull analysis by CFD tools
- Nominal wake calculation
- Self-propulsion computation
- Propeller geometry design, adapted to vessel operational profile
- Supply of blades compatible with the CPP core
- Supply of adapted rudder designed in conjunction with the propeller
The study comprised a first stage Express engineering analysis including complete hydrodynamic analysis of the hull and a second phase for implementation of the solutions, including the retrofitting of the CPP blades.
The analysis carried out showed the ineffectiveness of a redesign of the bow body. The variation in the load condition during navigation penalizes the possible improvements obtained through a bulb in the bow.
However, in the propulsion, the joint design of the adapted propeller and rudder has provided an optimization of performance of approximately 4%, together with an improvement in the ship’s maneuverability.
For the mechanical design of the blades, a Vicusdt technician traveled to the shipyards in Perú. There he carried out the precise measurement of the bases of the blade that would allow to ensure a quick and without incident substitution.
