A Review on the Drag Reduction Methods of the Ship Hulls for Improving the Hydrodynamic Performance

Hydrodynamic performance of a marine vessel mainly depends on the frictional and pressure resistance. Pressure drag reduction could be achieved by improving the shape of the vessels with implementation of modern hull forms. Hull forms optimization techniques could also be used for this purpose. Other techniques are needed to deal with the viscous portion of the total resistance, which is mainly...

An Adjoint Method for Design Optimization of Ship Hulls

We present a design optimization method for reducing the wave resistance (drag) of surface piercing hulls. Since this component of the drag is directly related to the energy contained in the wave structure that extends behind the ship, a fully coupled calculation of the flow field and wave evolution equation is required. The method combines the authors’ efficient automatic shape optimization te...

A Robot for the Unsupervised Grit-Blasting of Ship Hulls

This paper describes the design and the control architecture of an unsupervised robot developed for grit blasting ship hulls in shipyards. Grit blasting is a very common and environmentally unfriendly operation, required for preparing metallic surfaces for painting operations. It also implies very unhealthy and hazardous working conditions for the operators that must ca...

CALCULATION OF NON LIFTING POTENTIAL FLOW USING DESINGULARIZED CAUCHY\'S FORMULA

This paper discusses the disturbance velocity and potential as well as the total velocity formulation for non lifting potential flow problem. The problem is derived based on the Cauchy method formulation. The adding and subtracting back technique is used to desingularize the integral equations. The desingularized boundary integral equations are then discretized. The discretized equations can be...
