摘要： Provided is a method and apparatus for pulling a crown plug from a subsea horizontal Christmas tree, the method comprising: (a) providing a subsea lubricator having a longitudinal through bore and a jack attached to the subsea lubricator, the jack having a landing area, and the landing area having an opening which is fluidly connected to the lubricator's through bore; (b) providing a jacking string which includes a landing sub and a crown plug connector, the sub having a landing surface; (c) without the jacking string in step “b”, lowering the subsea lubricator of step “a”, to the horizontal Christmas tree and attaching the lubricator to the Christmas tree; (d) lowering the jacking string to the lubricator, and, while the landing surface of the landing sub is spaced above and not supported by the landing area of the jack, connecting the plug connector to the crown plug while the landing sub is above and not touching the landing area of the jack; (e) jacking up the jack such that the landing area of the jack contacts the landing surface of the landing sub, and pushes up on the jacking sub and jacking string causing tensile forces to be placed on the crown plug and releasing the crown plug from the profile of the Christmas tree; (f) while the lubricator remains attached to the Christmas tree, raising the jacking string and crown plug through and out of the lubricator and to the surface of the water to remove the tree; and (g) detaching the crown plug from the crown plug connector.
