•The insertion tube is a five foot long steel pipe about four inches in diameter with specially designed rubber baffles. The tube will be inserted into the Horizon’s riser to provide a direct connection.
•The direct connection, combined with the injection of methanol, will minimize the formation of hydrates that could block the flow of hydrocarbons.
•The riser insertion tube will be installed about 600 feet from the wellhead.
•The insertion tube will be connected to a 5,000 foot riser that will convey the hydrocarbons to the Transocean Discoverer Enterprise drillship on the surface.
• Once in place, oil will flow up into the Enterprise’s riser to the surface.
• Once at the surface, the hydrocarbons will be processed and oil will be separated from water and gas. The oil will then be temporarily stored before being offloaded and shipped to a designated oil terminal onshore.
•The Enterprise is capable of processing 15,000 barrels of oil per day and storing 139,000 barrels.
• A support barge will also be deployed with a capacity to store 137,000 barrels of oil.
