Semi-submersible platform Semi-submersible platform is a kind of movable building suitable for various projects, which is mainly used for various deep-water operations, such as offshore oil and gas drilling and lifting, or as other offshore production devices. The semi-submersible platform connects the underwater floating body and the superstructure through columns, which ensures the stability of the platform in bad sea conditions. This kind of free-floating platform relies on mooring system, dynamic positioning system or a combination of both to ensure a fixed working position. Semi-submersible platform ensures strength through sufficient weight and buoyancy through sufficient floating body volume. She can move between any two places and adjust the draft up and down through the ballast system. The working water depth of semi-submersible platform can range from 600 feet to 12000 feet (180 meters to 3600 meters). Jack-up platform is a movable platform, which can be fixed on the seabed through legs. The most popular design is to use three independent legs. Legs are driven up and down by hydraulic or electric power. During transportation, the platform floats through the hull and is towed to a new designated position by an ocean tugboat. Some barge jack-up platforms are self-propelled After the legs sit on the seabed (usually each leg is inserted into the seabed for tens of feet), the whole platform will be lifted to the safe "air gap" height allowed by the design wave height. Jack-ups provide more stable platforms than semi-submersible platforms, but they can only be placed in relatively shallow waters, usually less than 450 feet (136 meters). Special ships Special ships are ships used for special operations all over the world. It is usually designed and manufactured according to the special requirements of customers. Such as floating production storage tankers, pipe-laying vessels and self-dumping vessels.
