New jack-up design for severe seas
In designing a new generation jack-up to meet industry needs, Marathon Manufacturing drew heavily on experience gained in building and designing 40 percent of the self-elevating platforms currently operating world wide. The results in the Super 300 jack-up design, an extra large self-elevating jack-up drilling platform engineered to operate in harsh environments and suited to hazardous offshore areas such as the North Sea and the Far North Atlantic and Pacific where frequent storms can make re-supply of consumables impractical or impossible. The newly designed jack-up incorporates Marathon's combination slot and cantilever drilling pattern which allows full design storm capability for exploratory wells drilled through the slot. Conventional cantilever drilling may be carried out in lesser weather conditions. In the cantilevered position, the derrick can be extended 45-ft past the stern and 12-ft on either side of the centerline. This results in a total drilling pattern of 70*24 ft.
