Abstract

The usage of the multi-anchor positioning systems on the floating objects of ocean technology, operating in the deep waters of World Ocean, is discussed. The research aim is to define the development trends of the modern passive positioning systems of the deep water drilling platforms and development of the analytical dependences of the anchor mooring systems parameters on the drilling riser size and the water depth in their operation area. The statistical analysis of the technical characteristics of the passive positioning systems of the deep water drilling units is carried out. The analytical dependences of the drilling units parameters on the sea depth in the area of their installation are obtained. The research results can be applied in the design of ships and marine offshore structures, held in the operation area by the multi-anchor systems. The obtained analytical equations allow determining the approximate values of the passive positioning systems parameters, depending on the given sea depth in the location area of marine floating object.
