Abstract A ship hull design from the given offset points is one of the ways to create a new ship hull surface. The offset points are the rows of points obtained from the basis ship hull using the plane-surface intersection. A designer can create a hull surface for a new ship using the variation methods such as dimensional variation method and CP variation method. The created hull surface is presented using NURBS. The NURBS surface is a standard format in current CAD system but it has some drawbacks, for example, tensor product property, difficulty in local refinement, and not allowing T-junction, etc. Fore and after body shape of a ship hull is very complicated and it causes many control points of NURBS surface because of the tensor product property. In addition, more control points are required to create watertight hull surface among the NURBS surfaces of hull. T-spline is proposed by T. Sederberg to overcome these drawbacks of the tensor product property and it is extended to the computational analysis area recently. A number of control points can be reduced with the required continuity between the surfaces because the T-junction is allowed using T-spline. In this paper, the T-spline surface generation method is suggested to design the ship hull form from the given offset points. The result is compared with the NURBS surface and the benefit of the T-spline will be discussed.
