Case Study: an offshore platform operator restores full operations with HMS Professional Services and Anybus ProfiTrace

a offshore platform operator restores North Sea drilling operations in 2 weeks with HMS

An offshore platform operator in the North Sea faced a critical production halt when a PROFIBUS network failure stopped a key valve, forcing a nearly two-week shutdown costing an estimated €500,000 daily. Their redundant architecture failed to prevent the issue, and internal diagnostics could not identify the root cause. They engaged HMS Networks' Professional Services team for expert support.

HMS Networks dispatched a Support Engineer who diagnosed a defective valve controller as the immediate fault and revealed a deeper risk that the network's redundancy was flawed. After replacing the controller, HMS restored full platform operation. This not only stopped the massive daily losses but also provided the customer with a clear understanding of system weaknesses to reduce future downtime risks.
