As with gas leaks, large oil leaks or product leaks from operating lines are very easily detected, even more so because they create ever-growing sheens or slicks on the water surface. Barring some external influence, such as an anchor drag or jack-up deployment, these leaks start out as very small leaks and are typically caused by corrosion or material defects or may have been overlooked in initial construction. Identification of very small leaks in the initial pre-commissioning phase of any subsea system is the first step towards system integrity.
Ariosh, through its relationship with Come Monday, can identify such small leaks early on and will greatly lend to prevention or avoidance of possible catastrophic events typically accompanied by environmental damage and associated cleanup costs, expensive repair spread costs, loss of revenue and the ever present public relations / public image issues.
Our suite of leak detection systems provides us with means of detecting very small leaks in both newly constructed pipeline systems during hydro-testing and in systems already in service. Typical system selections are as follows:
New Construction
- Dye detectors (3 types)
- Passive acoustics
In-service Systems
- Passive acoustics
- Programmable Mass Spectrometer (PMS)
- Active acoustics
We offer multiple, independently operated systems that can be effectively utilized in locating small leaks in systems already in operation and/or during the hydro-testing of new construction.
- Didson Acoustic Package: this system can detect the presence of tiny bubbles or streams of tiny bubbles in the water column, regardless of water column clarity.
- Big Ears Hydrophone: this system can detect the sound a liquid or gas makes as it seeps through whatever defect or leak path that might exist.
- Programmable Mass Spectrometer: this system is capable of taking samples along a pipeline route or near a subsea assembly and determine, very specifically, the presence of any compounds in the inspection area having an atomic mass unit from 1 to 150 amu
- Dye detection systems; capable of identifying traces of fluoresce in dye as small as 1 ppm in the water column. All systems are capable of optimal performance regardless of water column clarity.
