| 81 | A brake for a hoisting apparatus | EP95850173.6 | 1995-10-03 | EP0708226A3 | 1998-01-07 | Sokalski, Marek; Zachariassen, Erik |
The present invention relates to a brake (4) for a hoisting apparatus (1). The hoisting apparatus comprises a hoisting line, a drum for the hoisting line, a hoisting motor and a brake system (4) for braking of the hoisting cable, the brake system (4) consisting of a hydraulic brake (8) and a mechanical brake (9). The invention consists of the fact that the mechanical (8) and the hydraulic brake (9) are connected to a common transmission (30) which is driven by the drum when this rotate freely, and the fact that the mechanical (8) and the hydraulic brake (9) are controlled by a common control means (5) for controlling the distribution of braking power between the two brakes. The control system distributes the braking power automatically between the brake systems. The transmission (30) can also be connected to an autodriller (10) for controlling the weight on the bit. |

The smart load pin may also include circuitry to convert the measured load to a digital value representative of the measured load, wherein the digital value represents the value of the measured load in engineering units and to transfer the digital value representative of the measured load to a control system located at a derrick. The data from the smart load pin may be used in adjusting, with a control system, operation of the draw-works system based, at least in part, on the received digital value representative of the measured load. | ||||||

| 88 | TOOL FOR CLOSED WELL OPERATION | EP16752712.6 | 2016-02-17 | EP3259440A1 | 2017-12-27 | CARLSEN, Tor-Øystein; LØKKA, Trond |
| The invention relates to a tool and associated method for making closed operation in subsea wells possible, without the use of cable or coiled tubing up to the rig or ship. The object of this solution is to move such operations to lighter and more cost efficient vessels or ships which are not necessarily required to handle hydrocarbons up to the deck of the vessel. The basis of maintaining two independent well barrier envelopes is met even if the tool and the method for operation does not require cutting functions for isolating the well from the environment. The tool comprises a hoist arrangement, a seal element and connection points. The localization and arrangement of these are essential for the invention. The invention also adapts for use of traditional workover systems as alternative, independent operation, if the new technique should not complete the operation as planned. | ||||||
| 89 | DYNAMICALLY AUTOMATED ADJUSTABLE DOWNHOLE CONVEYANCE TECHNIQUE FOR AN INTERVENTIONAL APPLICATION | EP14895956 | 2014-06-27 | EP3161242A4 | 2017-12-13 | POYET JEAN-PIERRE; SHEIRETOV TODOR K; CHATELET VINCENT; FOUCHER PIERRE-ARNAUD; CECCONI FABIO; HERMES AMIR |
| A method for conveying an interventional tool downhole in a substantially self-piloting fashion. The method includes moving the tool in the well while using a communicative conveyance line coupled to a winch at the oilfield surface. Thus, real-time readings regarding downhole tool speed, line tension, etc. may be analyzed at surface and utilized to adjust the moving of the tool in an ongoing feedback loop. As a result, the adjustments are made based on true circumstances downhole as opposed to surface-based readings which may otherwise be less accurate. Therefore, efficiency of the operations may be maximized, operator time freed and the likelihood of catastrophic line based failures reduced. | ||||||
