This paper outlines the overall project for development and installation of a low profile caisson-installed subsea Xmas tree. The system is designed to have all critical pressure containing components sub-mudline; with the reduced profile (height) above seabed, it provides for improved safety of satellite underwater wells from damage by anchors, trawl boards and even icebergs. The completion includes improved 3./one-half/ inch through flowline pump down completion equipment with deep set safety valves and a dual detachable packer head for simplified workover capability. The all-hydraulic control system incorporates a new design of sequencing valve for both Xmas tree control and remote flowline connection.
