\n Jack-up Offshore Platform<\/span><\/p>\n

Drilling Platform Wire Rope Tensioner Cylinder<\/h2>\n

Wire ropes on a jack-up platform carry the full weight of the platform during jacking. This cylinder tensions them through a pulley system \u2014 8,500 KN of thrust force, a 93.5% rod-to-bore ratio, and the highest force output in the jack-up hydraulic system.<\/p>\n

How Wire Rope Tensioning Works on a Jack-up Platform<\/h2>\n
<\/div>\n

\"Jack-up<\/p>\n

Some jack-up platforms use a wire-rope-and-pulley jacking system instead of (or in combination with) a rack-and-pinion mechanism. Steel wire ropes run along each leg, pass over pulleys at the top, and are anchored to the platform hull. The tensioner cylinder pushes against the rope anchor point, applying thrust force that is transferred through the pulley system to tension the wire ropes \u2014 this tension is what holds the platform at elevation.<\/p>\n

The 93.5% rod-to-bore ratio (580 mm rod inside 620 mm bore) is the highest in the entire offshore hydraulic cylinder<\/a> range. This extreme ratio produces a very small annular area \u2014 meaning the cylinder is designed almost exclusively for high thrust force on the extension stroke, with minimal retraction force. The wire rope only needs tension in one direction.<\/p>\n<\/section>\n

\n

Multiple Tension Configurations<\/h2>\n
<\/div>\n

Different platforms require different wire rope tensions depending on platform weight, leg count, rope diameter, and pulley arrangement. Korea Ever-Power offers standard tension configurations and custom designs:<\/p>\n

\n
\n
889 KN<\/div>\n

Light-duty jack-up barges and maintenance platforms. Smaller wire rope diameter, lower platform weight.<\/p>\n<\/p><\/div>\n

\n
1,112 KN<\/div>\n

Mid-range drilling platforms. Standard offshore exploration and production installations.<\/p>\n<\/p><\/div>\n

\n
1,245 KN<\/div>\n

Heavy-duty platforms with large topside equipment loads or harsh weather operating environments.<\/p>\n<\/p><\/div>\n<\/p><\/div>\n<\/section>\n
