Pulse Structural Monitoring, an Acteon company, unveiled three new software modules developed to complement its DrillASSURE drilling riser monitoring system software during a launch event at the 2012 IADC/SPE Drilling Conference and Exhibition in San Diego, Calif., on 7 March. Developed in conjunction with 2H Offshore, the new modules are DrillJOINT, DrillWINDOW and DrillADVISE and add to the current modules DrillFATIGUE, DrillTRANSIT and DrillVIV. The new interfaces are designed to help operators and contractors optimize use of their drill joint inventory, identify optimum operating windows and conduct safe campaigns by constantly analyzing conditions in real time.

“Improvement in safety, productivity and efficiency are increased and lower operating costs are the major benefits we see for integrating the software into (a company’s) operations,” said Jeff Diestler, business development manager for Pulse.

The DrillJOINT module is a complete inventory detailing the location, availability, technical specification, previous use and maintenance history of the owner’s drill joint. It enables  operators and contractors to source riser joints and assemble a robust drilling stack on screen prior to drilling, saving time and enhancing safety and efficiency.

DrillWINDOW offers pre-drilling analysis of static and dynamic operating windows and hang-off envelopes. The user inputs known environmental data, such as wave height, current velocity and mud density, then the software evaluates these data points against approved safety margins to calculate the fatigue life of the drill stack.

Lastly, the DrillADVISE module calculates parameters such as vessel position, flex joint angles and environmental conditions, then presents easily interpretable data in real time to guide the user on proceeding safely and efficiently. Feedback is presented in colors: Green shows all parameters are within thresholds, amber indicated caution or corrective action are required, and red is an instruction to disconnect immediately.

The combination of hardware and software modules creates the DrillASSURE system, which provides information to support day-to-day drilling operation and longer-term integrity management. The system uses real-time software in conjunction with inputs from sensors on the topside vessel, lower marine riser package and along the length of the riser.

“With our DrillASSURE systems (we can) monitor fatigue accumulation on critical components,” Mr Diestler said.
