Subsea system for the installation, suspension and removal of production and processing equipment

A method of installing, suspending and removing underwater equipment comprising:

• positioning a landing base module for landing and positioning the underwater equipment thereupon, the landing base module comprising a base member and a first buoyancy system;
• connecting the underwater equipment to one or more flowlines and risers using a plurality of connectors on the landing base module, wherein the flowlines connect the underwater equipment to an operations vessel at a surface of a sea, and the risers connect the underwater equipment to subsea equipment located on a floor of the sea;
• affixing mooring lines to the landing base module to secure the landing base module between the surface of the sea and the floor of the sea;
• attaching a second buoyancy system to the underwater equipment, the second buoyancy system having sufficient buoyancy to float the underwater equipment toward the surface of the sea when detached from the landing base module;
• adding ballast to a ballast system of the underwater equipment to lower the underwater equipment having the second buoyancy system;
• and
• positioning the underwater equipment having the second buoyancy system attached thereto onto the landing base module.
