Abstract
Techniques and systems to reduce deflection of a riser suspended from offshore platform. A guidance thrust delivery system (GTDS) includes a plurality of thrusters configured to be coupled to a riser of an offshore vessel. Each thruster of the plurality of thrusters is configured to generate a force on the riser of the offshore vessel to control a position of the riser in a subsea environment while the riser is suspended from the offshore vessel and decoupled from a seafloor.
