Abstract
A compensator system includes an expandable frame assembly configured to compensate for motion of a floating platform or vessel in relation to a seafloor below. The expandable frame assembly includes a retainer for supporting a tubular member and a tubular string below. When the expandable frame assembly is in a first position, a first tool assembly, such as a coiled tubing assembly, may be connected to the tubular string. Thereafter, the first tool assembly may be disconnected from the tubular string. The expandable frame assembly may then be moved into a second position, and a second tool assembly may then be connected to the tubular string.
Claims16
A compensator system comprising:
- an extendable frame assembly having an upper portion and a lower portion, the upper portion being slidingly secured to the lower portion and configured for vertical movement relative to the lower portion via a compensation assembly comprising one or more compensating cylinders, wherein each of the one or more compensating cylinders is connected to both the upper and lower portions;
- a sliding platform disposed on the upper portion of the extendable frame assembly, the sliding platform configured to slide horizontally relative to the extendable frame assembly, the sliding platform configured to support and suspend a coiled tubing assembly, wherein the coiled tubing assembly is configured for connection to a tubular member of a tubular string when the sliding platform is slid into a first position over a central space and a window of the extendable frame assembly;
- a retainer disposed below the sliding platform and the window and within the central space of the extendable frame assembly, the retainer configured to be secured to the tubular member of the tubular string and to support and suspend the tubular member and the tubular string, the tubular string extending from a surface to a subsea wellbore;
- and
- two or more supports extending from the upper portion of the extendable frame assembly to the retainer to suspend the retainer, the tubular member, and the tubular string, the two or more supports being directly attached to the retainer;
- wherein the compensator system is configured so that the upper portion of the extendable frame assembly is vertically lifted relative to the lower portion of the extendable frame assembly by actuation of the one or more compensating cylinders to place the retainer in a tensioned position for disconnection of the coiled tubing assembly from the tubular member and so that the sliding platform is slid horizontally into a second position, and wherein in the second position, the coiled tubing assembly is out of line with the subsea wellbore and wherein the central space and the upper window of the extendable frame assembly above the tubular member are empty.

A method comprising the steps of:
- a) providing a compensator system on a vessel or a floating platform, the compensator system comprising:
- an extendable frame assembly having an upper portion and a lower portion, the upper portion being slidingly secured to the lower portion and configured for vertical movement relative to the lower portion via a compensation assembly comprising one or more compensating cylinders, wherein each of the one or more compensating cylinders is connected to both the upper and lower portions;
- a sliding platform disposed on the upper portion of the extendable frame assembly, the sliding platform configured to slide horizontally relative to the extendable frame assembly, the sliding platform configured to support and suspend a coiled tubing assembly, wherein the coiled tubing assembly is configured for connection to a tubular member of a tubular string when the sliding platform is slid into a first position over a central space and a window of the extendable frame assembly;
- a retainer disposed below the sliding platform and the window and within the central space of the extendable frame assembly, the retainer configured to be secured to the tubular member and the tubular string, the tubular string extending from a surface to a subsea wellbore;
- two or more supports extending from the upper portion of the extendable frame assembly to the retainer to suspend the retainer, the tubular member, and the tubular string, the two or more supports being directly attached to the retainer;
- wherein the compensator system is configured so that the upper portion of the extendable frame assembly is vertically lifted relative to the lower portion of the extendable frame assembly by actuation of the one or more compensating cylinders to place the retainer in a tensioned position for disconnection of the coiled tubing assembly from the tubular member and so that the sliding platform is slid horizontally into a second position, and wherein in the second position, the coiled tubing assembly is out of line with the subsea wellbore and wherein the central space and the upper window of the extendable frame assembly above the tubular member are empty;
- b) causing the sliding platform to slide horizontally so that the coiled tubing assembly is in the first position and connected to the tubular member, wherein the coiled tubing assembly supports and suspends the tubular member and the tubular string;
- c) extending and retracting the extendable frame assembly to compensate for a sea level change over time;
- d) securing the retainer to the tubular member;
- e) causing the upper portion of the extendable frame assembly to lift vertically relative to the lower portion of the extendable frame assembly by actuation of the one or more compensating cylinders to place the retainer in a tensioned position;
- f) disconnecting the coiled tubing assembly from the tubular member, wherein the two or more supports and the retainer support and suspend the tubular member and the tubular string;
- and
- g) causing the sliding platform to horizontally slide to the second position so that the coiled tubing assembly is out of line with the subsea wellbore.
