An arrestor for reducing the velocity of moving icebergs and the like or large drifting objects relative to an off-shore fixed structure is disclosed. In use, the device extends outwardly from a fixed structure in at least one direction. A frame is adapted to be mounted to the structure in a manner which will allow an extending end thereof to move toward the structure. Nylon ropes or any other suitable elastic members are attached to the frame and to the structure and are utilized to provide an increasingly greater resistive force on the frame as the extending end of the frame is pushed toward the structure by an iceberg. Various embodiments of the general concept are disclosed.

Arrestor for large drifting objects

An ice-breaking structure having a platform member adapted to be flexibly connected to an off-shore fixed well shaft in a manner which allows the platform to lift and/or tilt relative to the shaft is disclosed. The platform member has at least one lower surface which slopes upwardly toward an outer edge thereof and is adapted to be positioned on the shaft so that the sloping surface extends both above and below sea level. As oncoming ice approaches and contacts the structure, the sloping surface lifts a portion of the platform upwardly onto the ice so that part of the weight of the platform is carried by the ice. This weight on the ice aids in breaking-up the same. Various embodiments of the general concept are disclosed.

Ice-breaking off-shore drilling and production structure

The specification discloses a single point mooring and fender suitable for large ocean going vessels. A dolphin is surrounded by a ring which is connected to the dolphin by a plurality of extensible resilient members adapted to absorb the kinetic energy of a hull moving against the fender.

Single point mooring and fender

The specification discloses a single point mooring for vessels comprising a base member adapted to rest on the ocean bottom, a cross member joined to the base member at one end thereof and a mooring post member joined to the base member at the opposite end and perpendicular to a plane intersecting the base member and cross member. Placing the single point mooring by floating, towing and sequential flooding is also disclosed.

Single point mooring

The specification discloses a single point mooring and fender suitable for large ocean going vessels. A dolphin is embraced by two fender bars in crossing relationship and having at least one resilient yielding member to resist spreading.
