METHOD FOR UNLOADING OF HYDROCARBONS BY MEANS OF COMPLEX FOR THEIR UNLOADING AND TRANSPORTATION AND COMPLEX FOR UNLOADING AND TRANSPORTATION OF HYDROCARBONS Russian patent published in 2009 - IPC B63B35/44 B63B27/24 

FIELD: construction.

SUBSTANCE: invention is related to field of construction and operation of marine shipment piers intended for provision of contact-less mooring of tankers in sea and transshipment of hydrocarbons onto them. Method for unloading of hydrocarbons consists in the fact in process of performance of operation of hydrocarbons unloading, operative control is carried out by turn of unloading boom (5), which is realised depending on value of tanker (2) motion relative to boom (5) point with continuous measurement of tanker (2) displacement value relative to boom point (5), and value of torque on rotary support device (4) to provide for boom point (5) location, directly above tanker (2), and also depending on value of torque on rotary support device (4), created by tension of mooring rope (11) by tanker (2), with displacement of the latter in horizontal plane. Complex for unloading and transportation of hydrocarbons is equipped with station of mooring-loading operations (13) control, located on shipment pier (1), system of automatic control of mooring-loading operations (16) in process of tanker approaching, mooring and holding in process of hydrocarbons unloading, and also facilities for control (17) of tanker position relative to mentioned pier and its unloading boom; facilities for force control (25) in mooring rope, facilities for control of tension force (26) in hose (6) of hydrocarbons unloading; facilities for control of load torque (27) on rotary support device (4), and also facilities (28) for provision of automatic emergency shutdown of hydrocarbons, moreover, elements of automatic control system facilities (16) are installed both on shipment pier (1) and on tanker.

EFFECT: improved reliability and safety of operation of "pier-tanker" complex.
