Are Your Offshore Assets Hurricane Ready?

11 March 2021

Energy and Resources

Over recent years the number of tropical storms and their intensity has steadily increased [1], posing real challenges to companies whose assets sit in their path. The devastation unleashed by hurricanes can severely disrupt operations and be costly in both lost revenues and repairing damage. To minimize disruption and to quickly recover from hurricanes, organizations are implementing strategies to become more resilient to this growing threat.

Resilient companies succeed.

There is increasing evidence [2] that organizations that plan for disruption, have the tools in place to respond quickly and adapt to events are ultimately more successful and profitable. For companies operating offshore in the Gulf of Mexico, who face the annual risk of hurricane season, they need to put in place the plans, procedures, and technology to ready their offshore assets for the disruption caused by tropical storms.

Jeffrey Lewis, Technical Advisor at BMT, has been helping organizations with offshore assets improve their resilience to hurricanes for almost 20 years. He said,

“Operators of assets will have a Hurricane Plan to follow when a tropical storm is nearing their offshore platform, this will involve scaling back operations and evacuating all personnel to safety. However, being ‘Hurricane Ready’, begins months before the start of the season. It involves readying and preparing critical systems used by remote engineers and asset managers to monitor the ‘health’ and structural integrity of the offshore assets during a hurricane. With all personnel evacuated, it is important to have a monitoring system that is working, and this requires regular maintenance. Otherwise, with no eyes on the platform, operators are effectively ‘blind’ and you really don't know what's happening as the storm passes overhead. Having a remote view of what's happening with the platform is critical to being able to respond to events quickly and resume operations safely.”

Inspecting your asset monitoring system

Hurricane season begins at the start of June and lasts through to the end of November. Offshore operators have a window of opportunity ahead of the season to proactively prepare their asset monitoring systems by updating their system or conducting maintenance. Routine maintenance involves calibrating sensors to ensure they are making accurate measurements as well as ensuring the system is in a good state of repair. This validation of sensor data involves both analyzing historic data readings but also visual inspection of the sensors.

Gerardo Uribe, Service Manager at BMT has been visiting and inspecting asset monitoring systems on offshore assets for over a decade. “There are a number of key things to consider when inspecting monitoring systems to ensure they are ready for hurricane season”, said Gerardo. He continues, “Some of the systems that we provide have a built-in power supply as well as communication systems. Either, because of the planned evacuation or the Hurricane itself, power to the monitoring system can be disrupted. So, as part of the maintenance we ensure that all the power systems are working correctly and continue to operate and communicate with shoreside operations throughout the storm.”

“We also look at the data and see that the sensors are making readings and they are giving a reasonable answer, but once we go offshore, we can do physical inspections of the sensors’ locations.  I have had wind sensors producing data that looked reasonable, however, when we went offshore, we discovered that the sensors were being shielded from the wind by the addition of new modules to the platform. Those types of things are very difficult to identify when we are only looking at the data, so being on the platform with independent sensors to verify the wind speeds and directions is important. This also applies to communication systems, antennas, or satellite receivers of the remote monitoring system. Equipment and devices installed after the initial installation of the monitoring system can interfere with the transmission system, downgrade the quality of measurements and can also interfere with GPS.”

Gerardo concludes, “A poorly maintained system, or one that fails to deliver information when it is needed, can often give false confidence by its presence, but delivers little when it’s needed in the critical moment.”

Ensuring offshore assets are hurricane ready involves both a resilience strategy as well as plans and procedures. However, without a well-maintained monitoring system that gives you sight of your asset, an offshore operator won’t be able to respond effectively to disruptive events.
