FIELD: hydrotechnical construction, running of self-lifting floating drilling rig in ice-covered water areas. SUBSTANCE: sea ice-resistant ice platform is used in the following way. During period of absence of ice self-lifting floating drilling rig sails from sea ice-resistant platform for 1-3 day passage which amounts to 260 to 800 km. Areas with such radii change from 0.25 up to 2.0 mln sq.km which means that prospecting operations can be conducted. With emergence of risk of appearance of ice fields in operational area drilling rig can be towed to sea ice-resistant platform, can be installed on it and operating holes can be drilled if necessary. EFFECT: expanded operational period of drilling rig. 1 dwg
