Jackup Lubrication

When the rig reaches the work site, the crew jacks the legs downward through the water and into the sea. This anchors the rig and holds the hull well above the waves. Because the rig is a sea-going vessel, it is subject to the same rules and regulations as ships are. The legs are what give the jackup its name.

They can be raised and lowered on ratchets in a process known as jacking up or jacking down. During jacking up, the legs go down and the rig goes up. During jacking down, the legs go up and the rig goes down until it floats on the surface of the water, then the legs continue to travel up until they tower above it.

It may be clear that when lubrication on board of such platforms, this is preferably done with high-tech lubricants. The conditions under which the racks of a lifting platform must serve require a specific grease that is more environmentally friendly, withstands extreme high loads, is highly water-resistant and offers optimum protection against wear.

In collaboration with its specialist suppliers Van Meeuwen has developed a new generation biodegradable lubricating greases for these specific applications where biodegradability plays a very important role. Other applications where these lubricants can be used very well are open gears, wire ropes, bearings, bushes, cylinder and piston units and guideways.
