NAPA 2009 Release

NAPA for Contract Design

In the early design stages, it’s vital to obtain reliable and accurate information quickly. It’s also essential that extensive design changes to the geometry model can be made swiftly and easily, as needed. With NAPA you can quickly and easily model surfaces and compartments into 3D, perform relevant detailed analysis, make changes and re-evaluate the design to ensure that it is technically feasible and satisfies the requirements of the nature, the ship owner, the shipyard and the authorities.

The NAPA system contains all of the functions necessary for the contract design of ships so that the optimum design solution is obtained before the contract is signed. Some examples of the many functions included are:

• Hull form design
• Compartments and internal geometry
• General arrangement
• Speed and power prediction
• Hydrostatics and stability
• Damage stability
• Loading conditions and intact stability studies
• Longitudinal strength
• Weight and cost estimation
• Required freight rate studies
• Tank calibration and capacity tables
• Freeboard and tonnage calculation
• General purpose optimization tools
• Drawings and documentation

Contract Design Made Easy with the Contract Design Manager

The Contract Design Manager application is intended for quick and easy creation of the whole 3D product model with NAPA at an early design stage. The Manager provides a logical workflow for contract design. The 3D product model created serves as the primary source of precise design information at stages leading up to the contract.
The Manager works as a user-oriented, visual interface for NAPA and manages the extensive design processes. Changes, adjustments and updates can be carried out easily with the Manager. All tasks, their relative order, up-to-date status and dependencies can be seen at a glance. Relevant detailed analyses can be performed and the feasibility of the design can be re-evaluated effortlessly, making the application ideal for the early design stages.

Advantages

The key benefit of the NAPA system is the unequalled speed at which design variations can be investigated and the final design accomplished. NAPA offers an integrated package with the wide variety of applications needed in ship design. The outcome of the early design with NAPA can be further developed in the latter stages of design, including meeting the final challenges of delivery and operation.
