摘要： 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.

摘要： 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.

摘要： A bottom-supported jack-up rig has a hollow ring mat with a central opening for accommodating a lower portion of a hull nested therein when the rig is in transit. The ring mat has a predetermined surface footprint sufficient to provide stability to the rig when embedded in the sea bottom. The mat buoyancy helps support the hull and the legs in a floating position when the rig is in transit, while allowing lowering of the mat to the sea bottom without assistance of a ballasting/de-ballasting means.
摘要翻译： 底部支撑的自升式钻机具有中空的环垫，中空开口用于在钻机运输时嵌入其中的船体的下部。 环垫具有足以在嵌入海底时为钻机提供稳定性的预定表面足迹。 垫子浮力有助于在钻机进入运输过程中将船体和腿部支撑在浮动位置，同时允许将垫子降低到海底，而无需通过压载/卸载手段。
