Abstract: Remotely operated underwater redirection plenum chamber for spill response. A method for operating an underwater redirection plenum chamber including aligning a first end of the redirection plenum chamber with a riser pipe having a fluid flow. A collar is lowered from the first end of the redirection plenum chamber, such that an inner diameter of the collar surrounds an outer diameter of the riser pipe. A plurality of barbs within the collar are activated to pierce and engage an inner surface of the riser pipe. A grip engages the outer diameter of the riser pipe. The grip has at least two counter rotating cylinders such that when rotated by the fluid flow the counter rotating cylinders create a seal allowing fluid to travel through the grip and into a first chamber of the redirection plenum chamber.
