20140251633 | Subsea Well Intervention System and Methods - A system for performing an intervention on a subsea wellhead, the system including a production tree having a central axis, a first end, a second end, and a first flow bore extending axially from the first end to the second end. The production tree includes a master valve disposed along the first flow bore, a swab valve disposed along the first flow bore between the master valve and the first end, and a shearing device disposed along the first flow bore between the master valve and the second end. The second end of the production tree comprises a connector configured to releasably couple to the subsea wellhead, and the shearing device is configured to shear a component extending through the first flow bore. | 09-11-2014 |

20110088481 | ATTACHMENT DISPLACEMENT SENSOR FOR MEASURING THE CHANGE IN LENGTH OF A SAMPLE AND MEASURING METHOD WHICH USES SUCH A SENSOR - The present invention relates to a contact displacement sensor for use in the mechanical measurement of the elongation of a sample by stretching. It further relates to a method for the measurement of the elongation of a sample using such a contact displacement sensor, a system for the measurement of the elongation of a sample using such a contact displacement sensor as well as the use of such a contact displacement sensor. The contact displacement sensor comprises an element with which the sample is contacted. According to the present invention the element is mounted rotatably and disposed in such a way that the tearing of the sample will rotate the element. Due to the element being rotated by the torn sample, only a small amount of energy will be transferred to the contact displacement sensor, which therefore will not be overloaded or damaged. | 04-21-2011 |
