FIELD: transport.
SUBSTANCE: claimed plant makes the bottom-to-surface joint between common floating support and sea bottom. It comprises multiple flexible lines including flexible pipes between said floating support and sea bottom whereat they are jointed to wellheads, equipment components or the ends of underwater pipes located on sea bottom. Note here that said flexible lines support multiple bearing and guide elements shaped to troughs. Note here that every said trough is located between two pipe sections including first section composed by suspended dual chain line between said floating support and said trough and second section composed of single chain line between said trough and the point of contact between said flexible line and sea bottom. Besides, the plant comprises bearing structure for troughs with lower part, a bed, laid or secured at sea bottom or penetrated therein. Plant upper p supports at least two troughs, top and bottom, arranged at different height so that lower point of aforesaid suspended dual chain line extending through the bottom trough is located under said lower point. Note also that the point of contact between of said versatility extending through the bottom trough is located closer to said bed than the point of contact between flexible line sea bottom extending through the top trough.
EFFECT: application of multiple sea bottom-to-surface joints, decreased overall dimensions and simple deployment.
