Üsküdar Engineering provides high-end design and consultancy services for any kind of marine vehicles with the support of state of the art software technology. From military vehicles to sailing multihulls we can solve your problems and design structures / vehicles for exact fitting to your needs.

Üsküdar Engineering mainly works on; Military surface combatants and submarines, stealth technology, oceanographic research vessels, single and multihulled motoryachts, single and multihulled sailing yachts.

Hull design works cover wide range of activities. Naturally the first stage is drawing the lines plan of the hull effectively. Traditionally this can be done with some paper, a pen, a batten and some weights. That's the way I love and learned many years ago for creating my first designs. But today computer technology can give us a little different approach. Drawing and nearly automatic fairing of the hull lines is available by working directly on the 3 dimensional geometry.

One of the main advantages of this type work over the traditional methods is that the designers now can focus on other important design works to improve their designs rather then drawing on paper by hand which requires more and more time around the drawing board.

The second can be the virtual reality supplied by computer which is very precious for today's marketing arena.

But for my point of view the biggest advantage of CAD in marine design appears by using this 3D CAD geometry when combined with CAE (Computer Aided Engineering) and CAM (Computer Aided Manufacturing) technologies.

Today analysis of any complex marine vehicles and structures can be done by using finite element analysis (FEA) and computational fluid dynamics (CFD) which yet available for desktop computers.

Our geometry modeling services are based on hybrid surface and solid modeling and covers; hull lines plan, offset table, deck plan, general arrangements plan, engine room arrangement plan, transverse and longitudinal cut drawings, construction plan, shell expansion, sail plan, structural modeling, mold design and some rendering and virtual reality.

The keel is one of the most critical elements for the single hull sailing vessels. Therefore the keel design is required special attention when high performance desired.

On the other hand offshore sailors need better course keeping capabilities for their vessels. Once again the keel characteristics play very important role.

The rudder is another example of marine vessel elements which have to be carefully designed to get low drag and high lift without being exposed to ventilation and cavitation.

The structural design of keel and rudders are vital because you can not cruise without them in most cases and when they are lost this means you are in a trouble.

To get a successful design for both elements the combined usage of solid modeling, finite element analysis and computational fluid dynamics technologies and experience are required.

For solving some of engineering problems, it is unavoidable to work on hydrodynamics and aerodynamics area. After the fast developments in the both hardware and software industries these high-end, very expensive, hard to use technology begin to enter on many designers desktop. So Üsküdar Engineering can give some of this type support for:

A marine structure can be exposed to extremely high and variable loads during it's service life. Winds and waves, engines and propellers, slamming, vibrations and pressure whatever the source is, the effects of the possible loads over the structure has to be carefully examined for maximum possible security and performance.

With today's finite element analysis technology it is available to simulate real life conditions effectively and testing the vessel before building it and in most situations there is no need to build expensive prototypes.

Our structural analysis support covers; steel, aluminum alloys, titanium and modern composites for;

Stability is the most important aspect of a ship design if it is not sufficient all other aspects of a design is unsuccessful. Our stability services covers;

• Stability analysis of any hull form including submarines.
• Hydrostatic curves.
• KN-GZ curves.
• Tank analysis.
• Comparmentation and damaged condition analysis.
• Longitudinal strength analysis for static and wave conditions.

It is possible to predict power requirements and performance of a marine vehicle when in early design stages.

There are many methods developed for power prediction of ships and boats. These methods mainly differs and categorized according to the hull types. When some methods have been developed for cargo ships others for sailing monohulls, for power catamarans, planing vessels etc.

But all of these methods are based on testing and experiences in the past so they just predicts the performance and can not give exact results for most of design works. To achieve more realistic and sensitive result there are two possible approaches:
