In this study, a wireline riser tensioner (WRT) system was dynamically simulated to analyze the dynamic response of the riser string in a mobile offshore drilling unit (MODU) such as a drilling rig or a drillship.
The main function of the WRT system is to sustain the tension to avoid buckling, regardless of the MODU motion. The Phantom Tollbooth is a book full of interesting characters. Read this lesson to meet Milo, the book's main character, and find out how he changes over the course of the story.

Borehole heat exchangers are a growing technology in the area of house/building air conditioning, most of all in northern Europe. In order to have a good project, we need to have a reliable value of ground thermal conductivity, which is normally obtained by interpreting the data retrieved by running a thermal response test.
Different are the ways of interpreting the data. These responses are correlated with the physical tyre response that are measured using a kinematic and compliance (K&C) test rig in the laboratory. A Design of Experiments (DoE) study, followed by an optimization process, is performed by sampling the material properties of the rubbers to simulate the FE model and match the tyre responses.
