Subsea production system having arctic production tower

摘要

A subsea production system for conducting hydrocarbon recovery operations in a marine environment, including a trussed tower having a first end including a base residing proximate the seabed and a second end having a landing deck configured to receive and releasably attach to a floating drilling unit. The system also includes one or more hydrocarbon fluids storage cells. The storage cells reside at the seabed proximate the base of the trussed frame. The system further includes subsea production operational equipment that resides within the trussed frame near the water surface and is in fluid communication with the hydrocarbon fluids storage cells. A method for installing such components is also provided.

1. A subsea production system for conducting hydrocarbon recovery operations in a marine environment, the marine environment comprising a body of water having a surface and a seabed, and the production system comprising:
an elongated trussed frame having a first end and an opposing second end, the first end comprising a base residing proximate the seabed; a landing deck at the second end of the trussed frame, the landing deck being configured to receive and releasably attach to a floating drilling unit, and the landing deck residing below the water surface a sufficient distance to avoid contact with a floating ice sheet; one or more fluid storage cells residing at the seabed proximate the base of the trussed frame, at least one of the one or more fluid storage cells being a hydrocarbon fluids storage cell for receiving hydrocarbon fluids; and subsea production operational equipment residing above the seabed and proximate the second end of the trussed frame below the landing deck, the subsea production operational equipment being in fluid communication with the at least one hydrocarbon fluids storage cell.
