Abstract
Disclosed are compliant variable tension risers () to connect deep-water subsea wellheads () to a single floating platform () in wet tree or dry try systems. The variable tension risers () allow several subsea wellheads (), in water depths from 1220 to 3050 meters, at lateral offsets from one-tenth to twice the depth or more, to tie back to a single floating platform (). Also disclosed are methods to counter buoyancy and install variable tension risers using a weighted chain ballast line ().
