  • Dual-derrick ice-worthy jack-up drilling unit
    Patent number: 8911179
    Abstract: The invention relates to a jack-up rig. The inventive rig would work like a conventional jack-up rig while in open water with the hull jacked up out of the water. However, in the event of ice conditions, the hull is lowered into the water into an ice defensive configuration. The hull is specifically shaped with a lower portion that is an ice-bending surface to bend and break up ice that comes in contact with the hull while in the ice defensive configuration. Furthermore, the jack-up rig comprises at least two derricks.

  • Modular heavy lift system
    Patent number: 8888410
    Abstract: A single heavy lift system is made of modular units, each of which has a pair of supporting legs carrying a transverse beam therebetween. The beam is engaged to the supporting legs through jackup units that allow the transverse beams of several modular units move in unison and thus increase lifting capacity of the system. The modular units can be formed as modular, self-propelled units, transported to the site, where the lifting task is to be performed if necessary. The system can be positioned in a dry dock or offshore.

  • DUAL-DERRICK ICE-WORTHY JACK-UP DRILLING UNIT
    Publication number: 20130101357
    Abstract: The invention relates to an ice worthy jack-up rig that may extend the drilling season in shallow water off shore Arctic or ice prone locations. The inventive rig would work like a conventional jack-up rig while in open water with the hull jacked up out of the water. However, in the event of ice conditions, the hull is lowered into the water into an ice defensive configuration. The hull is specifically shaped with a lower portion that is an ice-bending surface to bend and break up ice that comes in contact with the hull while in the ice defensive configuration. Furthermore, the ice worthy jack-up rig that comprises at least two derricks so as to double the exploration efficiency and lower the relating costs.
