Jabarkan Ngaran dari Jackup Rig dalam bahasa sunda

Jack-up rigs are so named because they are self-elevating—with three or four movable legs that can be extended (“jacked”) above or below the hull. Jack-ups are towed to the site with the hull, which is actually a water-tight barge that floats on the water’s surface, lowered to the water level, and the legs extended above the hull. When the rig réaches the drill site, the crew jacks the legs downward through the water and into the séa floor (or onto the séa floor with mat supported jack-ups). This anchors the rig and holds the hull well above the waves.
