Underwater corrosion surveys

Underwater corrosion can have serious consequences for offshore structures, such as oil and gas platforms, pipelines, and ships. It can lead to structural damage, leaks, and other problems that can be costly to repair. That’s why it’s important to regularly conduct underwater corrosion surveys to assess the condition of these structures and identify any potential issues.

There are several methods for conducting underwater corrosion surveys, including visual inspections, ultrasonic thickness measurements, and corrosion coupon testing. Visual inspections involve using divers or remotely operated vehicles (ROVs) to inspect the structure visually, looking for signs of corrosion such as pitting, scaling, and discoloration. Ultrasonic thickness measurements involve using specialized equipment to measure the thickness of the structure’s metal, which can indicate the extent of corrosion. Corrosion coupon testing involves installing small metal coupons on the structure and later retrieving and analyzing them to determine the rate of corrosion.

Underwater corrosion surveys are typically conducted by specialized companies or contractors, using trained technicians and advanced equipment. The results of the survey are used to develop a corrosion management plan, which may include repairs, coatings, and other measures to prevent or mitigate further corrosion.

Overall, underwater corrosion surveys are an essential part of maintaining the integrity and safety of offshore structures. By regularly assessing the condition of these structures, we can ensure that they continue to operate safely and reliably for years to come.

We have extensive equipment for any underwater operation and have the qualified personnel to complete the work safely and efficiently.
