Marine Engineering

The advent of computer technology has significantly aided and excelled the introduction of new and innovative ways in which to design, build, out- fit and maintain ships and boats. The ensuing section is dedicated to the latest products and services geared toward making the life-cycle process more efficient and cost effective.

High-Tech AC Hits The High Seas

As both cruise operator and cruise passen- ger can attest, a cruise ship's air conditioning system is arguably one of the more critical comfort function systems. Thus, the securing of a high-value, high-profile newbuilding refer- ence is of particular importance in ensuring a product or system's long-term acceptance.

Following successful test installation of

Monovent onboard different cruise ships, ABB

Flakt Marine won a prestigious order for more than 2,000 Monovent units to be supplied to

Star Cruises for new cruise liners being built at

Meyer Werft in Germany.

The new Monovent single duct VAV air ter- minal unit features the latest in sensor and electronic technology. It has an integrated flow sensor that makes tedious adjustment work unnecessary, and ensures the correct air flow irrespective of varying supply air pressure.

A mini-flow function is designed to reduce the airflow when the balcony door is opened, helping to conserve huge amounts of energy that would otherwise be wasted. Up to four

Monovent units, connected to a common duct system or to separate ducts with different sup- ply air pressure, can be controlled by one con- trol panel, a useful function for larger areas in need of superior air distribution. Monovent is type-approved by DnV and LR.

BMT Employs State-Of-The-Art Earth

Observation Techniques In Product

Development

British Maritime Technology Limited (BMT) has identified for commercial development two new global information products for the mar- itime market, products that could potentially greatly aid the safety and efficiency of ships at sea.

The first product is an integrated wave cli- mate database, designed to provide more com- prehensive data on wave heights, frequency and swell than current systems. BMT believes that the data would be of particular value for naval architects in designing new vessels; for offshore engineers planning production sys- tems with the continued move towards produc- tion in deeper waters; and for coastal engineers planning coastal defenses with rising sea lev- els. The second product is a new and innova- tive operational procedure for the production of bathymetric charts, which measure depth, based directly on Earth Observation data for coastal waters. Bathymetric charts are essen- tial to all sectors of the maritime industry and currently can only be produced via hydro- graphic surveys. Due to cost and time involved in this method, it is estimated that approxi- mately 30 percent of existing global coastal

New Version Of Catia Offers Valuable New feels

An innovative CAD/CAM solution has added to its capabilities, with the recent release of Catia-CADAM Solutions Version 4,

Release 2.0. The system is utilized by top design and construction firms in a variety of industries — notably Finland's Deltamarin and Germany's Meyer Werft — and the new version offers three new and 37 enhanced products designed to make the system a greater efficiency enhancement tool.

The new Version 4, Release 2.0 supports customers from 2-D drawings to digital mock-up methodologies and notably, expands customer competitiveness and productivity in manufacturing, analysis and mock-up. "We use Catia to design internal areas, such as the bridge and the galley, along with the actual hull, deck structure and propul- sion systems," said Juhani Kivi, vice director of EDP with Raisio, Finland-based

Deltamarin. "With Catia's 4-D Navigator and the significant enhancements in the

Catia-CADAM Shipbuilding Solutions, more than ever we can present an easily visualized end-to-end solution to the ship owners."

While the Catia system is designed as a multi-industry support solution, the Release 2.0 of Catia-CADAM Shipbuilding Solution is designed to bring shipbuilders and suppliers an integrated "end-to-end" or "concept opera- tion" solution, with extended modeling fea- tures, industry standard support and new generative capabilities in the ship hull steel- work design product. The system disciplines are designed to cooperate through the product's life cycle, from initial hull design through out- fitting. It is designed as a common base for design, configuration management, manufacturing, commission, maintenance and operations.

Another of the new products offered in the upgraded package is the Lathe Machining

Programmer, which provides extensive turning designs for such operations as roughing, groov- ing, threading and finishing. The new release also offers full integration across all Catia manu- facturing product suites to enable mixing mill, drill and lathe operations in a seamless fashion.

The new release increases the productivity of drawing creation through 2-D view sketching with ease-of-use features for automatic drawing layout, automated view positioning and faster annotation.

Other system enhancements include: the capability to generate the 3-D solid representation of composite material parts and integrate the representation within a digital mock-up; and the extension of Catia 4-D Navigator, the tool for digital mock-up inspection and simulation, to become CAD independent to support access to any CAD system.

Peter Motikat, technical director at the well-respected Meyer Werft facility in Germany, a shipyard that is known for its adherence to the latest technological trends and systems, had this to say about the system: "Since 1989, we have been using Catia extensively in designing our ships, including one of the largest cruise liners in the world." "We go beyond such things as general arrangement, structural steel, HVAC, piping accommo- dation and electrical design, and use Catia for such crucial features as on-board shopping malls, swimming pools and entertainment centers."

Catia-CADAM is from Dassault Systems, and is marketed, distributed and supported by IBM worldwide.
