Hull Form Parameterization Technique with Local and Global Optimization Algorithms
The paper is presented on the development of a designer friendly hull form parameterization and its coupling with a local and a global optimization algorithm: the well known Sequential Quadratic Programming (SQP) and the more recent evolutionary Particle Swarm Optimization (PSO). These two algorithms are representative of classes with rather opposite characteristics (derivative–based and deriva...
متن کاملCONSIDERATION OF DESIGN FOR PRODUCTION PRINCIPLES IN SHIP HULL DESIGN
In designing for ship production, the production method should be considered and it’s possible to reduce the manufacturing cost in designing procedure. A review of background of ship design that had minimized production costs, shows the principles and problems of these methods. Modern designing methods for manufacturing, considers hydrodynamic efficiency and less manufacturing cost. Quant...
متن کاملMargins of safety in FPSO hull strength
Recent studies were carried out to determine the variation in safety factors (between the applied loading and the capacity) of FPSOs currently operating in the UK Sector of the Central North Sea, and designed using either a class rule type approach or a more advanced hydrodynamic – FE type approach. Results from these studies seem to indicate that the safety factor in both cases is similar, sin...
متن کاملEfficient Parallel Convex Hull Algorithms
A bstract-In this paper, we present parallel algorithms to identifv (i.e., detect and enumerate) the extreme points of the convex hull of a set of planar points using a hypercube, pyramid, tree, mesh-of-trees, mesh with reconfigurable bus, EREW PRAM, and a modified AKS network. It is known that the problem of identifying the convex hull for a set of planar points given arbitrarily cannot be sol...
متن کاملPartial convex hull algorithms for efficient grasp quality evaluation
We present two algorithms to efficiently determine the value of two grasp quality metrics formerly proposed in literature. The first one is heavily used in practice but has some drawbacks, e.g., it is not scale invariant and it does not focus on the disturbance forces that will occur in practice when the robot grasps an object. The second one overcomes these limitations, but is rarely used beca...
