Heave Compensation Cylinders
Whether your heave compensation system needs to be active or passive, the most important aspect relates to its ability to withstand the strong natural forces and harsh offshore conditions. Large hydraulic cylinders from Van Halteren Technologies are designed to resist heavy wear and tear that is caused by these harsh conditions. For example, riser tensioner cylinders and heave compensation cylinders operate efficiently because of their quality large hydraulic cylinders.
Riser Tensioner Cylinder
| Riser tensioner cylinder | Example |
|---|---|
| Piston diameter | 560 mm |
| Piston rod diameter | 230 mm |
| Stroke length | 16,300 mm |
| Function | Stabilizing drill string by compensating motion |
Jacking Cylinders
Depending on the requirements, and based on the type of work and the environmental conditions, the choice between various platform concepts may lead to jack up platforms. Rexroth develops drive and control systems for various jacking system types and sizes, which are used in numerous self elevating platforms (SEPs). Not only that, Rexroth can provide state of the art large hydraulic cylinders that are used in both rack & pinion installations and positive engagement systems for offshore and inland applications.
Jack-Up Cylinders
| Jack up cylinder | Example |
|---|---|
| Piston diameter | 600 mm |
| Piston rod diameter | 280 mm |
| Stroke length | 3,150 mm |
| Function | Lowering / lifiting the legs |
Skidding Cylinders
The process of skidding oil platforms involves having an excellent and reliable x-y skidding system. Part of having an excellent skidding system depends on the quality of the hydraulic cylinders. Large hydraulic cylinders from Van Halteren Technologies are reliable, accurate and of excellent quality.
Deck Mating Cylinders
Transporting and installing offshore platforms is all about force and precision. Knowledge of the procedures and experience with the often hostile maritime conditions is crucial. Like no one else, Van Halteren Technologies is capable of engineering state of the art technology for elevating, transporting, positioning and installing extreme heavy loads. Worldwide float-over barges, floating cranes and special vessels have been equipped with Van Halteren Technologies large hydraulic cylinders.
