A Jack-Up Platform is a floating barge that has movable legs attached to the hull.

These legs can be retracted and extended vertically, meaning that once it makes contact with the sea bed, the platform begins to move upwards and out of the water.

The hull on which these legs are built is water-tight, buoyant, and similar to a ship. It has ballast tanks, living spaces (if required), a bridge for operators to work from, and machinery for lowering and raising the legs.

Jack Up refers to how the legs are jacked up or down.

The first thing to note is that Jack Up platforms are primarily used in shallow and intermediate water depths. They perform well in depths up to around 120 meters.

At deeper depths, they face issues in structural compliance (discussed later).

Jack Ups can be used for drilling and installation operations, and our mobile units as compared to other gravity-based structures.

They can be either towed like other barges or have propulsion units at the aft that move the structure under its own power. The self-propelled variants are less common due to the large power that such units consume.

Instead, tugs with higher-than-average bollard pull are used. We are specialists for Building Jack up Barges.
