System and vessel hydrocarbon production and method for intervention on subsea equipment

摘要

A system for operation and service of at least one hydrocarbon-producing well(24) and of equipment (27, 35), which is disposed under water, for further transportof the well stream, where the system comprises - at least one pipeline (32), - atleast one booster unit (27), - a vessel (10) comprising - an anchoring system aboutwhich the vessel can rotate or swivel, - means (60, 61, 62) for conducting an interventionon subsea equipment, - means for communication with and control of the at leastone well (24) and other equipment (35), - means for injecting chemicals into thewell streams (25, 32), - means (73) for transferring to and inserting pigs in thepipeline (32), - means (14, 15) for production of energy for operation of subseaequipment, - means (22) for transferring energy from the means (14, 15) for productionof energy to the booster unit (27) and any other subsea equipment.
