The OPC Foundation Takes Ownership of the MDIS Sub-Sea Standard

Source: 12/8/2021, Location: North America

The OPC Foundation (OPCF) is proud to announce that it consolidated and took over the MCS-DCS Interface Standardization (MDIS) specification ownership. Effective immediately, as with all OPCF Companion Specifications, MDIS is freely available for adoption by all interested parties at no additional cost. The OPCF MDIS working group, co-chaired by Markus Koenig from SubSea, Tim Fortin from Honeywell, and Paul Hunkar from DS Interoperability, now oversees the ongoing maintenance and expansion of the standard. Original MDIS network group members will continue working in the OPCF working group. The OPC Foundation invites all members interested in helping shape the future of the MDIS specification to join the MDIS working group.

MDIS was formed with a vision to optimize and standardize communications between subsea Master Control Stations (MCSs) and topside Distributed Control Systems (DCSs). A standardized MCS-DCS interface simplifies the implementation of data communications and increases data quality. Companies that adopt the MDIS standard, whether they are the operators or automation vendors, benefit from simplified integration and commissioning of the MCS–DCS interface, reduced maintenance efforts, and minimized risk of interface failures that lead to downtime and expensive subsea equipment repairs.

Shreekant Mehta, Senior Vice President, Energy at Sagentia Innovation (which incorporated OTM Consulting) commented, “MDIS was started as an OTM network in 2009 with support from operators and vendors. The collaboration seen within MDIS is unique, and we have seen some great technology development leading to three interoperability testing meetings where interfaces were proven. We are delighted to see the MDIS specification reach maturity and have a new home with OPC who will maintain and update this specification as needed. We’d like to thank the operators, integrators, vendors and OPC who have worked together to create this industry standard.”

The OPC Foundation wishes to acknowledge the international network of companies for their work over the past twelve years to make MDIS a reality and OTM Consulting for hosting.

The original MDIS network companies include:
• Aker Solutions
• Baker Hughes GE
• BP
• Chevron
• ConocoPhillips
• Dril-Quip
• Emerson
• ENGlobal
• ExxonMobil
• Honeywell
• Kongsberg
• OneSubsea
• Petrobras
• Prediktor
• ProServ
• Rockwell Automation
• Shell
• Siemens
• Softing
• Equinor
• TechnipFMC
• TotalEnergies
• W-Industries
• Woodside
• Yokogawa

Stefan Hoppe, President and Executive Director of the OPC Foundation, observed, “MDIS is an important offshore Oil and Gas production standard that serves as an example of the vital role OPC UA companion specifications increasingly play in the industry.”

Mr. Hoppe continued, “The success of OPC UA-based standards like MDIS comes from more than the universal information modeling OPC UA offers. OPC UA also addresses underlying infrastructure issues associated with data connectivity security and future-proofing, which translates to saved time and effort for standards bodies, easier to implement products for vendors, and more complete end-to-end solutions for end-users.”
