Apparatus and methods to operationally link (couple/decouple) a plurality of relatively massive, complimentary payload platforms (i.e., suspended machinery and ROV) at relatively deep working depths in an unstable marine environment (water column) while the payload platforms are in-transit. An apparatus includes a suspended machinery, an ROV, a capture collar, an extendable/retractable harpoon, and actuating machinery to controllably effect extension and retraction thereof. A method includes providing an in-transit suspended machinery having a capture collar, providing an in-transit ROV having an extendable/retractable harpoon, approaching the in-transit suspended machinery with the ROV, maneuvering the ROV so as to bring an end of the partially extended harpoon into aligned proximity with the capture collar, and further extending the harpoon so that it securely engages the capture collar.

1. An apparatus enabling the capture and release by an in-transit ROV in a water column of an in-transit suspended machinery in the water column that is suspended from a link from an in-transit marine surface vessel, platform, or other surface or sub-surface structure, comprising: a suspended machinery;an ROV;a capture/release mechanism disposed in one of the ROV and the suspended machinery;a linearly extendable/retractable harpoon respectively disposed in one of the suspended machinery and the ROV, wherein the harpoon has a geometrically-shaped, capture head and a capture groove, further characterized in that the harpoon has no moving parts, further wherein the capture/release mechanism is a bi-stable, push-to-capture and lock/push-to-release mechanism; andactuating machinery associated with the linearly extendable/retractable harpoon to controllably effect linear extension and retraction thereof. 2. The apparatus of 1, wherein the push-to-capture and lock/push-to-release mechanism includes a ratchet and pawl assembly. 3. The apparatus of 1, wherein the harpoon has a tapered leading edge on a distal end thereof. 4. A method for capturing an in-transit suspended machinery that is suspended in a water column from a link from an in-transit marine surface vessel, platform, or other surface or sub-surface structure by an in-transit ROV in the water column, comprising: providing an in-transit suspended machinery and an in-transit ROV, each, respectively, having one of either a capture/release mechanism and a linearly extendable/retractable harpoon, wherein the capture/release mechanism is a bi-stable, push-to-capture and lock/push-to-release mechanism and wherein the harpoon has a geometrically-shaped, capture head and a capture groove, further characterized in that the harpoon has no moving parts;approaching the in-transit suspended machinery with the ROV, wherein the linearly extendable/retractable harpoon is partially extended and is aligned with the capture/release mechanism;maneuvering the ROV so as to bring the distal end of the harpoon into alignment with the capture/release mechanism; andfurther extending the harpoon until the geometrically-shaped capture head and the capture groove engage the bi-stable capture/release mechanism in a locking engagement. 5. The method of 4, further comprising at least partially retracting the engaged harpoon so as to draw the ROV and the suspended machinery closer to one another into a securely coupled arrangement. 6. The method of 5, further comprising transferring a unit payload disposed within at least one of the ROV and the suspended machinery to the respective suspended machinery and the ROV. 7. The method of 4, further comprising: releasing the captured suspended machinery from the ROV by further extending the harpoon until the geometrically-shaped capture head engages the bi-stable capture/release mechanism in an un-locking engagement; andmaneuvering the ROV away from the suspended machinery.
