Free hull shape expertise.
Unfortunately, there is still no single standard for the formation of the surface of the hull. Everyone involved in surface modeling uses their own methods and representations. An erroneous opinion was rooted in the shipbuilding community that the hull surface made in any CAD system is smooth by definition and can be immediately transferred to production. This is a very dangerous misconception.
On average, 80% of the hull parts are adjacent to the hull surface. The curved shell plates are also very dependent on the quality of the shape of the hull. The designer modeling the details of the hull works in local areas of the hull and cannot evaluate the quality of the entire surface. It is not so dangerous, when surface smoothing errors are detected at the stage of modeling parts of the hull, otherwise all this problems goes to the production stage. In this case, it is no longer possible to avoid the high cost of man-hours to correct these errors and extra material usage. I think that everyone, who dealt with the construction of the ship's hull, faced similar situations.
According to our statistics, a very large percentage of the surfaces of the hulls provided to us for verification have certain errors made during smoothing. Using the Shape Maker, it’s not difficult for us to detect these errors and give them some recommendations for their elimination. This is a completely free of charge service.

5 年Very interesting! ..but in the end, when the ship is build, how is its real form? I mean, there would be also some resistance due to welding, due to human errors, due to aximmetry, etc..etc.. Lots of time we think at the hull geometry as in the CAD software, in the end, the real geometry would be different. How can on take in account this difformity? Thanks!
