Abstract: A grabber accessory for attachment to a prime mover is described, and may include a stanchion, pivotable arm having a proximate end attached to the stanchion to form a pivot point of the arm and a distal end extending generally transverse to the stanchion and terminating in at least one downward tine, and hydraulic cylinder attached between an upper end of the stanchion and a surface of the arm between the proximate and distal ends. The hydraulic cylinder may be configured to raise and lower the arm under hydraulic control from a main hydraulic feed of the prime mover. The accessory further includes a pair of vertically spaced clamping assemblies attaching a lower portion of the stanchion to frame member surfaces of the prime mover so as to secure the accessory in an upright position.

Abstract: A gravity base offshore production platform structure and, more particularly, a production platform for use in an arctic environment, including an encircling structure having a predetermined configuration the protection of the offshore structure in iceberg-infested waters which are capable of resisting the destructive forces of an impact produced by a large iceberg. The gravity base offshore production platform structure consists of a monolithic, massive concrete structure of a configuration providing a plurality or horizontal array of upright, mostly cylindrical compartments, which is supported on a concrete or slab foundation nesting on the marine floor. Generally, although not necessarily, the compartmented structure rises above the marine surface and is covered by a concrete slab or similar covering structure to thereby form closed compartments within the monolithic structure.
