original hull surface that was initially inside the box is deformed. Te parts that were originally outside the box are kept as they were and the continuity is maintained at the box boundary region. NAPA’s Box Transformation Manager
Application (BTMA), based on the box transformation function, gives the user experience in hull form development. It provides a way of working in the hull form developing environment. NAPA highlights that the Manager is intuitive and easy-to- use providing a convenient way of creating and editing transformation boxes and comparing the original and transformed hull surfaces. Te user is able to produce a transformed hull form the fairness of which is kept as equivalent as that of the original’s in a short amount of time. NAPA Release 2012.1 includes the first
implementation of this tool. In this first phase, the method can only be applied to surfaces with Non-uniform rational basis spline (NURBS) representation. Prepared
Naval, Commercial & Offshore
NAPA patch surfaces, which include a NURBS representation can be transformed, but the curve network that was used in the preparation cannot yet be modified. Te modification of the curves and other objects will be handled in future releases. In addition, ClassNK and NAPA have
announced that they will collaborate to provide a comprehensive solution for Ship Energy Efficiency Management Plans (SEEMP) for ship operators. By sharing
their expertise, this
co-operation will provide a service for ship owners, operators and shipbuilders to aide them in reducing energy consumption and emissions, fuel costs and find an effective solution for SEEMP, for which regulation will come into force on 1 January 2013. In order to ensure that the collaborative
SEEMP solution will be both effective and practical for use on actual vessels, ClassNK and NAPA are working closely with Japanese shipbuilder, Imabari Shipbuilding Co. Ltd.
A trial version of the new solution is
expected to be completed within the year, and upon completion it will undergo extensive real world testing on vessels owned and operated by an Imabari Group shipping company. Feedback from this verification testing will be used to further develop and refine the system prior to final release. Imabari Shipbuilding will also make use of the system and the results from its verification tests to further improve the performance of new vessels built at its shipyards. Te SEEMP solution from ClassNK and
NAPA will combine modules to optimise trim, route and speed optimisation and weather routing with an analytics service to offer operational efficiency and decision support. Te system will allow owners and operators to respond quickly and adapt operations in real-time to capitalise on latent efficiencies within operations in order to increase eco-efficiency and reduce fuel consumption as a solution for SEEMP, says NAPA.

THE MAJOR CHALLENGE FOR THE SHIPBUILDING SUCCESS IS TO ACHIEVE MORE RELIABLE, PROFITABLE AND SOPHISTICATED VESSELS WITH VERY TIGHT COSTS IN LESS TIME
