Abstract: A small and light weight microconical interface fitting may be attached to the surface of a space vehicle or equipment to provide an attachment device for an astronaut or robot to capture the space vehicle or equipment. The microconical interface fitting of the present invention has an axisymmetrical conical body having a base portion with a torque reaction surface for preventing rotation of the interface grasping tool; a cavitated, sunken or hollowed out intermediate locking portion which has a cavity shaped for receiving the latches of the grasping tool and an upper guiding portion for guiding the grasping tool into axial alignment with the microconical interface fitting. The capture is accomplished with an interface grasping tool. The grasping tool comprises an outer sleeve with a handle attached, an inner sleeve which may be raised and lowered within the outer sleeve with a plurality of latches supported at the lower end and a cam to raise and lower the inner sleeve.

Abstract: An apparatus is disclosed for inspecting, cleaning and/or performing other tasks in connection with a welded joint between intersecting tubular members of an offshore platform a substantial distance beneath the water surface. The apparatus includes a support body adapted to be moved onto and removed from one of the tubular members, and a carrier rotatable about the body, when clasped about the one tubular member, and having the task performing devices thereon for traversing the joint as the carrier is so rotated.
