Anti-Collision Assessment and Prediction Considering Material Corrosion on an Offshore Protective Device

Corrosion Assessment of Offshore Oil Pipeline Based on Ultrasonic Technique

In this paper, an intelligent ultrasonic inspection device for offshore pipeline inspection and a corrosion assessment of offshore pipeline software are developed to inspect the damage state of Chinese pipelines. The main function of the inspection system is ultrasonic signal pre-processing, data acquisition, de-noising and data compression in real time. The system includes a micro-computer, tr...

Probabilistic Pitting Corrosion Risk Assessment of Welded Offshore Steel Pipelines

Steel structures continuously exposed to offshore marine environments are prone to corrosion. This can be of major economic and perhaps of environmental significance. The risk of these scenarios occurring can be assessed using good quality data, good quality corrosion and pitting models and structural reliability assessment. Recently, improved models for the prediction of longer term corrosion ...

Anti-Collision Issue Analysis in Gen2 Protocol Anti-collision issue analysis considering capture effect

Avian collision risk at an offshore wind farm.

We have been the first to investigate whether long-lived geese and ducks can detect and avoid a large offshore wind farm by tracking their diurnal migration patterns with radar. We found that the percentage of flocks entering the wind farm area decreased significantly (by a factor 4.5) from pre-construction to initial operation. At night, migrating flocks were more prone to enter the wind farm ...

IX. INHIBITOR EFFECTIVENESS ON CO2 CORROSION WITH SAND Introduction Erosion, corrosion, and erosion-corrosion are common problems in offshore

Erosion, corrosion, and erosion-corrosion are common problems in offshore pipelines, tubing and pipe fittings. Corrosion has an important impact on the total cost of oil and gas production. Considering the diversity of corrosion related problems, CO2 corrosion (sweet corrosion) is probably the material degradation mechanism most extensively assessed in this industry over the last 30 years. In t...
