What will a poorly-maintained valve cost you?

In 2010, BP’s shareholder value dropped 50 per cent within three months as a consequence of one environmental disaster that happened at BP, the oil and gas company. A failing safety valve cost BP 6.1 billion US dollars to repair the oil spill. As you would expect, BP risked the license to operate because of the SHE (safety, health and environment) matter. The authority questioned BP’s overall safety procedure at the problem site and all of the BP operating platforms. Twelve years have gone by. BP has spent on cleanup efforts to compensate victims, civil and criminal penalties, payments to state and local governments, and other expenses, paid out more than $70 billion since 2010.

The disastrous oil spilling case mirrored the reactive maintenance approach of the company. Would a proactive maintenance approach mark the distinction?

Emergency and contingency plans are critical for acting quickly to the incident. But this is only one part of the story of crisis management. Under the valued-driven maintenance concept and practice, the business owner would wish to maximise asset utilisation for productivity with the lowest possible maintenance cost. The maintenance period is also part of the consideration. Once the asset is under maintenance, it will stop operation. The pause in production is equivalent to a loss of value generation. The laws and regulations covering safety, health, and the environment are inherent in the maintenance management plan, though it sounds like the SHE department’s job.

Therefore, it is significant to solve the manual scheduled inspection and maintenance problems by identifying potential flaws without interrupting regular operations. If maintenance happens in the industrial area, a common challenge is to identify the defect. And in some cases, the assets deteriorate little by little until breaking down one day. A proactive, well-scheduled, even value-added maintenance management plan and practice are encouraged to preserve the SHE culture.

How can we pick out the faulty point without manual inspection, without disrupting the operation? It will be as tricky as accomplishing a picture-hunting. The noise emitting from the assets may give the maintenance manager a hint.

An acoustic camera is an imaging device to locate and characterise sound sources. It consists of a group of microphones – called a microphone array. They are simultaneously acquired acoustic and video signals to form a representation of the location of the sound sources when coupled with a high-performance optical video camera. An acoustic camera provides clear evidence and instant documentation of noise reduction by letting you listen with your eyes. The acoustic camera’s sound analysis localises and identifies the sound emission, empowering the quality control with finding faults resulting in variations in the soundscape.

The acoustic camera has successfully achieved the following. Find out more with us about what is for your project.

  • Filming sound leakages in a highly reflective office environment, 
  • Filming breakout noise from cafes and concert venues, 
  • Measuring the impact of traffic noise in apartment living room, 
  • using the acoustic camera inside a caravan car to find squeak and rattle noise, 
  • Filming low-frequency structure-borne noise with an acoustic camera, pinpointing low-level sanitary noise in an apartment building, 
  • Identifying short time high, pitched squeak noise from an electric window in the car door, 
  • Finding a weak acoustical point in room diving modular walls,
  • Identifying low-frequency tonal noise in windy and noisy conditions.
