A jack-up barge also known as a jack up rig is a work platform which is used so that the offshore works of construction can be carried out rather easily and safely. They are used as a stable base for servicing and construction of several overwater structures including bridges, drilling platforms and wind turbines. It consists of a buoyant hull that is fitted with several movable legs which is capable of raising the hull over the sea. The hull enables the easy transportation of the unit as well as all the attached machinery to the location that you desire. The legs of such units are often designed so as to penetrate the seabed. You can hire a jack up barge easily these days by contacting the related company.
How Will The Jack-Up Barge Be Secured?
The jack up barge works efficiently by being able to operate in the most complex marine environments including heavy seas, huge tidal ranges and strong currents.
The barge has four self-elevating legs that can easily be lowered or raised. The barge would then be transported with legs up. The barge is then kept at the port where the tug boats and the support vessels tow the barge into the correct position. It is here that the legs of the barge would be jacked down and then secured with anchors. It is made sure that the barge is secured well above the water level taking into account the tidal activity and the local wave. The task of preloading then takes place.
After preloading is done, the jacking that has been set up is then used to elevate the barge above water to a predetermined height. This is done so as to ensure that the construction work can be carried out rather safely. The advanced jacking system uses pinion gear and rack. The pinion gears get driven by hydraulic or electric motors and the rack is then attached to the legs.
The jack-up rigs are also known as specialized barges which are quite similar to a gas or oil platform. However, they are used as a base so as to service other structures like long bridges, drilling platforms and offshore wind turbines. A barge in general terms is a flat-bottomed boat which is built for the transportation of heavy goods on the river and the canal.
Jack-Up Barges in Shallow Waters
The jack-up barges or rigs are mostly placed in shallow waters. Now these are generally less than 120 metres of water. But, there is a particular class of jack-up barges which is known as the premium or the ultra-premium one which are known for possessing the operational capability in certain water depths which range anywhere between 150 to 190 metres.
The jack up barges having a high payload that have a rich range of standard monohull and self-elevating platforms can easily be found these days. To diminish the mobilization effort and price, all of the hire a jack up barges are constructed and equipped in such a way that it would ensure a rather easy beginning of any kind of foundation or marine projects.
