Research of vessel construction is very helpfull during wreck identyfication. Accoriding to engineering knowledge we analyse construction and general view plans. It allows to compare wreck construction with building plans. Some particular construction solutions are very characteristic. They apper during vessel construction in specified periods of time and specified construcion bureaus. Used technology and bindings structure is priceless cue during identyfication.
