A New Safety and Stability Enhanced Riser Control System: An Integrated Hybrid Riser Tensioning System
Volume 1: Offshore Technology, 2012Co-Authors: Yin Wu, Edward Peter Kenneth Bourgeau, Ross BaldickAbstract:This paper presents the framework for a novel riser tensioning system using a hybrid arrangement for energy management. This hybrid tensioning system, which integrates electrical tensioners and energy storage elements with existing hydro-pneumatic tensioners, is designed to enhance the safety of a deepwater riser system by improving stability and dynamic performance. Four control modes are investigated for the framework implementation: 1. Normal operation mode for active heave compensation. 2. Riser-recoil mode to control recoil on sudden release and minimize unwanted riser upward movement. 3. VIV suppression mode to reduce disturbances induced by ocean currents in the riser string and to extend riser fatigue life. 4. Reconnection mode provides control to allow reconnecting the LMRP to the BOP without using the Drawworks, freeing the Drawworks from the time consuming procedure of landing the LMRP and tensioning the riser. A replacement strategy is proposed so that one can update any existing system to the hybrid riser tensioning system by replacing certain pairs of hydro-pneumatic tensioners with the novel electrical riser tensioners to achieve smooth system upgrade and better system reliability.Copyright © 2012 by ASME

Finite Element Calculation and Analysis of Model HXJ158C Offshore Workover Rig
China Petroleum Machinery, 2013Co-Authors: Rg Petro-machineryAbstract:Referring to the practical engineering design example of offshore workover rig,applying the ANSYS software to conduct the simulation calculation and simplifying the real rig structure,the finite element model of the whole rig'upright operating condition and the derrick's lifting condition was established adopting the overall modeling analysis method.The slenderness ratio was judged and it was found that the natural frequency of the first ten orders falls within 12 Hz and the vibrating amplitude of the derrick is greater than that of the drill floor base.The rotation speed of Drawworks is between 0 and 415 r/min;the corresponding disturbance frequency is between 0 and 7 Hz;the maximum rotary table-driven rotation speed is 221 r/min;its disturbance frequency falls within 4 Hz.Therefore,the disturbance excitation caused by the Drawworks will easily excite the resonance of the derrick's first six orders.The disturbance excitation caused by rotary table driving will easily excite the base's lateral movement.In light of this condition,the resonance should be avoided in order to make the frequency of Drawworks and rotary table go far away from the resonance zone frequency.The present study can offer the basis for the design and use of workover rig.

Electric Control Gas Control System of the High Speed Drum Clutch and Low Speed Drum Clutch in Drawworks
Mechanical Engineer, 2015Co-Authors: Tian JianxiAbstract:The clutch on off of domestic traditional mechanical drilling rig adopts pneumatic control. Because the Drawworks is mounted on the lower rear floor, the control of clutch is realized in the driller's console of high drilling-floor,which resulted in the control gas pipeline of high speed drum clutch and low speed drum clutch is longer, reaction time is prolonged, the clutch can not be timely hanging and releasing. To solve this problem, control system of the high speed drum clutch and low speed drum clutch has been improved, the pneumatic control instead of electric control gas. The control reaction is accurate and sensitive, clutch overcomes lag phenomenon of clutch remote control; at the same time system affected little by temperature is small, suitable for working in cold area, it accords with the characteristics and requirements of rig automation.
