System and method for deploying subsea and downhole equipment

A system for deploying well equipment to a subsea well, comprising:

• a vessel;
• a deployment frame disposed on the vessel, wherein the deployment frame comprises a protruding section extending as a cantilever beyond an external edge of the vessel;
• wherein the protruding section comprises an aperture formed therein to facilitate construction of the well equipment through the protruding section;
• and
• an actuation assembly coupled to the protruding section to selectively transition the protruding section to a collapsed, split, or retracted orientation out of a deployment path of the well equipment while the well equipment is suspended through the protruding section and/or in the deployment path;
• wherein the protruding section comprises two separate halves disposed adjacent each other and the actuation assembly comprises a latching mechanism that, when activated, enables the two halves to rotate away from each other and in opposite directions away from the deployment path.

• wherein the protruding section comprises an aperture formed therein to facilitate construction of the well equipment through the protruding section while the well equipment is supported over the external edge of the vessel via the protruding section;
• and
• an actuation assembly coupled to the protruding section to selectively transition the protruding section to a collapsed, split, or retracted orientation out of a deployment path of the well equipment while the well equipment is suspended through the protruding section and/or in the deployment path;
• wherein the protruding section comprises a slot extending from the aperture to an external edge of the protruding section.

• wherein the actuation assembly is operable to transition the protruding section while the well equipment is suspended through the protruding section and/or in the deployment path.

A method, comprising:

• constructing a well equipment system comprising at least a downhole tubular or tool string over an external edge of a vessel, wherein the well equipment system is supported over the external edge via a protruding section of a deployment frame disposed on the vessel, wherein the protruding section comprises an aperture through which at least a portion of the well equipment system is disposed;
• suspending the well equipment system from a deployment cable;
• splitting, retracting, or collapsing the protruding section of the deployment frame out of a path of the well equipment system while the well equipment is suspended through the protruding section and/or in the deployment path;
• and
• with the frame out of the path, lowering the well equipment system toward a subsea wellhead in a single trip.
