Method for the formation of algorithm elements for designing a vessel for the subsea technical operations support using a database of similar vessels

Abstract

The elements of the algorithm for designing vessels for underwater technical work such as formation of the power station of the designed vessel are considered in the paper. These are formation of the power station of the designed vessel, selection and installation of crane and diving equipment, hardware intended for use on a vessel of manned submersibles and determining the dimensions of mobile operation equipment intended for future installation on a vessel being designed to perform appropriate technological operations on the sea shelf, based on the data of a group of the same type vessels. The algorithm is intended for definition of the main dimensions of the designed vessel, namely, a number of the installed diesel generators and ratios of total power of the power station with a width, loading capacity of the crane and power of a propulsive complex of the designed vessel. Systematization of the used crane equipment as for performance of cargo and underwater and technical works, and for hardware service is performed. Systematization of a diving complex, hardware and the manned submersibles assumed to use on the vessel is also performed. The relation between the dimensions of the main deck and ship structures necessary for the installation of mobile technological equipment and complexes using databases of the same type of vessels is systematized. Using the existing design experience and a database of ships of similar purpose, a formula that allows, as a first approximation, to estimate the sizes of the power plant, load-lifting devices and diving equipment planned for installation on the designed vessel that provides service to submersibles of any type has been compiled.
