The IMO ship identification number is a unique ship identifier; the IMO company and registered owner identification number is used to identify uniquely each company and/or registered owner managing ships of at least 100 gross tons (gt).
There are three principal methods of conveying a new ship from building site to water, only two of which are called "launching". The oldest, most familiar, and most widely used is the end-on launch, in which the vessel slides down an inclined slipway, usually stern first.
Frame-first construction involves laying down the framework of the vessel before attaching the planks to the boat. This is normally done by erecting a "master frame" in the center of the keel, and deriving the shapes of the other frames using a curved piece of wood stretched between the frame and the end posts, or through a geometric curve.
