METHOD AND SYSTEM FOR CAPTURING HYDROCARBONS FROM A LEAKING OILWELL AT A PREDETERMINED SEABED LOCATION

摘要

Method and system for capturing hydrocarbons from a leaking oilwell at a predetermined seabed location, in which the steps are applied of: a. deploying a dome near the predetermined seabed location; b. moving the dome to the predetermined seabed location; c. capturing the hydrocarbons from the leaking oilwell into the dome; d. providing near the predetermined seabed location a predetermined number of anchor means around the leaking oilwell, which anchor means are equipped with pull wires, and e. attaching the pull wires to the dome for pulling the dome in position above the leaking oilwell. The dome is placed in position on top of a base plate which is placed on the predetermined seabed location prior to moving the dome to the predetermined seabed location.
