There is a need at many remote oil and gas field sites for data typically collected by specialized sensors. To meet this need, a remote CP monitoring platform was developed that combines a dedicated two-channel CP rectifier/test station monitoring device and a dedicated two-channel sensor/transducer monitoring device into one unit.
Structures such as steel bulkheads, steel piles supporting piers or wharfs, offshore drilling platforms, and other similar structures may be cathodically protected with either sacrificial galvanic anode systems or impressed current systems.
As pipelines age, it is important to verify the effectiveness of the coating and cathodic protection systems that protect them against external corrosion, and implement remedial actions if necessary.
A major U.S. university is using funding from Phillips 66 to develop a new outdoor pipeline integrity lab, which will include buried pipe with an active rectifier to simulate real-life activities.
The principle of a close-interval potential survey is to record the pipe-to-soil potential profile of a pipeline over its entire length by measuring potentials at intervals that do not significantly exceed the depth of the pipe.
Cathodic protection (CP) is an important component for the sustainability of many metal structures. The most common impressed current voltage sources are rectifiers, which can break down. Well-maintained rectifiers can provide uninterrupted CP, which reduces repair costs and labor/technician time.
New probe technology developed from recent academic research can conduct safety-critical testing inside galvanizing kettles holding molten zinc at 450 °C.
The measurement and interpretation of cathodic protection (CP) data in plants or other complex facilities present inherent challenges where mixed metals are electrically continuous within the protected structures’ CP system.
A second generation of a polyaspartic urethane two-coat coating system with improved wet adhesion and corrosion resistance was developed in recent years for application in warm climates with high humidity.
A novel approach is presented regarding corrosion assessment and cathodic prevention of foundations for electric transmission towers in the Persian Gulf region.
Initial test results have shown higher corrosion resistance, increased mechanical strength, and better abrasion resistance when using epoxy resin-based coatings formulated with graphene.
Iridium is a hard, brittle member of the so-called platinum group of metals in the periodic table. As an alloying element, it increases the corrosion resistance of titanium and palladium. We know that corrosion is a reaction between a material and its environment, so why not have a look at the most corrosion resistant metal in the periodic table.
The third and final deadline for underground storage tank owners and operators to meet new federal requirements from the U.S. Environmental Protection Agency for spill, overfill, and corrosion protection is October 13, 2018.
Recent field experiments demonstrated that a cathodically protected perforated monopile structure could create an environment with more favorable corrosion mitigation, air quality, and water chemistry compared to a sealed structure. A newly designed perforated offshore monopile system could help mitigate corrosion within the often flooded interiors of offshore wind turbine support structures.
The pocket-sized cathodic protection (CP) interrupter records continuous waveforms during close interval surveys and provides accurate and defensible data. The technology includes both high-speed waveform datalogging and automated waveform analysis.
