HOUSTON – Diamond Offshore Drilling Inc. has launched its Stack-View service, a solution that applies 24/7 real-time monitoring, data visualization, and analytics to identify trends and detect anomalies in BOP performance across its rig fleet.
The leading indicators derived from the service are said to enable predictive maintenance and subsea downtime prevention, increasing drilling productivity and lowering the total cost of the well.
The real-time data gathered and analyzed by the underlying technology in Stack-View is continuously overlaid or “stacked” with historical data, then data visualization, trending, and advanced analytics is applied to predict when BOP components will fail or when maintenance is required, the company said.
This shift to predictive maintenance from time-based maintenance mitigates stack pulls and maintenance-induced issues, with the ability to reduce non-productive time by up to 50% depending on the water depth and well complexity.
Developed in partnership with Deepwater Subsea LLC, the customized Stack-View platform and dashboards are expected to accessible from any mobile device or computer and any location by early 2020.
Marc Edwards, president and CEO of Diamond Offshore, said: “Subsea equipment repairs and maintenance continues to be a major contributor to a rig's non-productive time, resulting in great expense to both drillers and operators. We continue to look for ways to improve operational efficiencies and reduce operators’ total cost of ownership to make the economics of offshore drilling more competitive.
“With our Stack-View service, we will be able to monitor and analyze the health of each BOP across our fleet in real time to make more data-driven decisions that create further cost-savings and performance improvement."
The company said the new platform is fully configurable and has the future capability to integrate with its Sim-Stack service and BOP failure reporting database. Combined, these systems will provide a holistic view of a BOP’s health as well as past and future performance, allowing the company to transition to conditioned-based maintenance to further reduce costs while increasing subsea equipment reliability.
In addition, the company said the combined solutions will support operators in meeting BSEE’s requirements for 21-day BOP pressure testing frequency.
