The design and building processes of new ships are increasingly becoming an exact science, whereas a refit requires more experience and often a degree of improvisation. All this is of course based on the solid foundation of professional knowledge at Vuyk Engineering Groningen (VEG).
The refit process itself generally starts with a feasibility study, a new General Arrangement and, if desired, outline sketches and renderings. A report is produced with the implications of the refit including an overview of all necessary activities (engineering and workshop). It provides a solid starting point for a quotation for the complete refit.
The next phase starts with fairing the new lines and determining the new (hull) shape, followed by production of detail and class approval drawings for construction, outfitting and technical systems. This phase includes conducting all the required class and strength calculations.
If required a complete set of cutting files can supplied, including nesting tables and product information for plates and profiles. To accelerate the refit process even more, the client can choose to have this ‘package’ translated into an actual metal building kit, a so-called 3D puzzle, so the yard can have the new section(s) manufactured before the ship arrives at the yard.
To guarantee a good, seamless connection to the existing shape and construction, VEG always survey the vessel first using their experience and state of the art 3D laser imaging techniques. After the refit an inclination test and sea trials are performed as input for producing all the required documents and approvals.
