Flame Arrester Replacement on a Deep-Water FPSO
Enhancing Safety & Uptime
Background
A leading offshore energy producer operating a deep-water FPSO faced growing challenges with its existing flame arresters Flame Arresters A flame arrester, deflagration arrester, or flame trap is a device or form of construction that will allow free passage of a gas or gaseous mixture but will interrupt or prevent the passage of flame. . According to project documentation, the units were generating excessive pressure losses, were difficult to clean, and required crane assistance during every maintenance Maintenance Combination of all technical and administrative actions, including supervision actions, intended to maintain or restore a unit in working order. cycle.
Cleaning inefficiencies forced monthly production stoppages, and the extended cleaning time often required work to be moved to an onshore workshop. The operator needed a solution that would reduce downtime, improve safety conditions, and minimise maintenance burden, without altering the existing piping layout.
Solution
PROTEGO® supplied a set of advanced Detonation Detonation Explosion propagating at supersonic velocity and characterized by a shock wave (EN 1127-1: 1997). Flame Arresters designed specifically to enable easy offshore maintenance. Based on the technical material in the report, the devices featured:
- Individual stabilized FLAMEFILTER® discs for easier handling and improved cleaning efficiency
- Tap-drain features to control condensation build-up and maintain stable performance
- Custom-matched dimensions to fit the existing equipment Equipment Machines, appliances, fixed or mobile devices, control parts and accessories, and warning and prevention systems, whether separate or combined, intended for the generation, transfer, storage, measurement, control, and conversion of energy, and for the processing of materials, which have their own potential source of ignition and may cause an explosion. footprint, eliminating the need for piping modifications
- On-site commissioning, ensuring seamless transition from the legacy system to the new units
These design improvements directly addressed the operator’s constraints around space, safety, and offshore accessibility.
Result
The FPSO achieved significant operational gains after the replacement. Internal performance summaries note improvements such as:
- Higher cleaning efficiency and improved handling
- Marked reduction in cleaning frequency
- Shorter maintenance duration, allowing work to remain offshore rather than shifting to onshore facilities
- Lower manpower requirements and reduced safety risks during servicing
Collectively, these enhancements contributed to better production continuity and improved safety conditions for offshore personnel.
The upgraded flame arresters have delivered a major improvement in both performance and maintenance safety. The solution has supported our goal of maintaining system integrity while reducing operational burden.
