In high-stakes offshore drilling operations, split-second decisions can mean the difference between control and catastrophe. What if your rig could make one of those decisions for you—automatically?
The Hidden Risk in DP-Operated Rigs
In the world of dynamically positioned (DP) drilling rigs, maintaining position over the wellhead is mission-critical. But even with the most advanced and powerful DP systems, the risk of a drift-off or drive-off event, where the rig moves unintentionally due to system failure, environmental forces, or human error, is ever-present.
When this happens, the marine riser can be forced off its allowable deviation from its vertical axis, placing unacceptable mechanical stress on critical riser/BOP/wellhead components. If not handled swiftly, this stress can cause serious equipment damage or, worse, a loss of well control.
So, what can you do to ensure that emergency protocols are triggered in time, even when the rigcrew can’t act fast enough or are unable to act, and other safety systems fail?

A Smarter Failsafe: Future Production’s Automatic Disconnect System (ADS Trigger)
The Automatic Disconnect System (ADS) is a mechanical safety mechanism engineered to protect the well and riser infrastructure during unintended and uncontrolled rig movement, specifically drift-off or drive-off events on dynamically positioned (DP) rigs. When traditional response systems depend on human action or control system software (i.e. Emergency Shutdown Systems (EDS)), the ADS Trigger adds a mechanical and fully independent, automatic layer of protection.
Key Installation Point: Lower Flex Joint
The system is physically mounted onto the lower flex joint, directly above the LMRP/BOP. This is a critical stress point during riser deflection events, making it the optimal location for the ADS Trigger.
Pros with Implementing ADS
Independent of rig control systems
Because the ADS Trigger operates mechanically and autonomously, it remains effective even during power loss or system failure—providing a critical layer of redundancy.
Proven performance in harsh environments
Over the years, rigs in some of the world’s toughest drilling environments have adopted ADS Trigger technology and the technology has proven its worth on several occasions.
Cost-effective insurance
Compared to the financial and operational consequences of a failed emergency disconnect, the investment in an ADS Trigger is modest—and well worth it.
Meets regulatory requirements
On the Norwegian Continental Shelf (NCS) it is now a requirement to include an independent safety mechanism to ensure (emergency) riser disconnect in events where other systems fail.
The ADS Trigger fulfils this requirement.
