Design applications. In this way a pre- liminary steel structure for a ship can be generated from parameter values in a matter of few hours and several different alternative design and dimensioning approaches can be analyzed for steel weights, surface areas, section modulus etc. In continuing its trends towards sys- tem integration and improvement, last

December AVEVA presented a range of major new features to VANTAGE

Marine 11.6 and Tribon M3, with the aim to improve the integration of basic design and detailed design, contributing to new and more flexible ways of organ- izing shipbuilding design activities.

For example, there is often a require- ment to start cutting steel at an early stage of a shipbuilding project, some- times even before the final approval has been obtained from the classification societies. The structural engineers work with the overall classification view of the ship while the detailed designers usually are responsible for certain indi- vidual hull blocks. This presents a dilemma in creating and maintaining two versions of the design simultane- ously, one for basic structural design and one for the detailed design that supports the parts manufacturing tasks.

VANTAGE Marine 11.6 and Tribon

M3 now present a potential solution.

The systems maintain two parallel views of the design in the Ship Model data- base: a design view for the structural engineers and a production view for the detailed designers. The structural engi- neers create and maintain the design panels while the detail designers work with the production panels. The produc- tion panels are created from the design panels using the automatic block split- ting facilities. After block splitting, the two views of the steel structural model are kept synchronized so that any change to a design panel will automati- cally impact the corresponding produc- tion panel. A late change from the clas- sification society or the ship owner will become available not only in the basic design model but also immediately influence the parts definition work.

Likewise a change to an individual part becomes known to the designers.

Many shipyards develop the basic design within their own organization while they often subcontract all or part of the detailed design work. The new features of VANTAGE Marine and

Tribon support this work process by synchronizing the design and production panels when the production panel data is being delivered from the subcontractor to the shipyard. In practice, this means that classification drawings can easily be updated with changes made by the subcontractors. In the same way, data for parts manufacture and assembly is updated with any changes made by the subcontractor during detailed design.

With the new features in VANTAGE

Marine 11.6 and Tribon M3 it is possible to create alternative block and assembly definitions from the same design using the block splitting function. The alterna- tives can be analyzed and the choice of production facility can be postponed until late in the process. In this way the work involved in creating the manufac- turing information is minimized.

Confirmation

While company proclamation and technical detail are, of course, relevant, nothing speaks to a system's success quite like orders, and AVEVA has enjoyed increasing success in this regard. Last May, prior to the launch of

VANTAGE Marine 11.6, Hyundai

Heavy Industries (HHI) selected

AVEVA's marine products for the design and production of ships and offshore projects at their shipyard in Ulsan,

Korea. The contract, worth more than $12.5 million, includes implementation of the current AVEVA marine products with licenses for more than 1,000 designers. In addition to Korea, AVEVA considers penetration in to the China market as a major plank in its platform to dominate the world of vessel design. "As a country, they are determined to buy their way in" to the shipbuilding market, Longdon said. The company announced several recent contracts that illustrate its move to this end, in late 2005 signing a contract with Dalian

New Shipbuilding Heavy Industry (DNS) to extend its application of

AVEVA's Marine solutions for both its shipbuilding and offshore businesses.

Additionally, AVEVA will provide pro- fessional training and onsite consulting services to DNS to ensure efficient and
