Loss Prevention, Through Improved Inspections No one wants a failure, especially into our waterways or surrounding areas. With offshore and marine oil terminals being the lifeline to many refineries, this poses a great dilemma. Many of these piping systems are situated in non-cost-effective locations or are simply inaccessible using standard methods.
It doesn’t matter who you are – external corrosion is an ever-growing concern due to the aging of our systems. In the past, piping over water has been inspected using boats or walkways with little success, or using floating or fixed staging at a serious expense. With the advancement of technology, techniques such as long range ultrasonic testing have tried to cover the gap.
Today, companies are addressing the accessibility, inspection and corrosion mitigation needs of these piping systems by using rope access. Rope access provides a hands-on, safe and cost-effective alternative.
Skilled technicians, certified in the required disciplines, can safely remove and clean corroded areas, and then measure and record accurate remaining wall thicknesses.
They can also coat the required areas per the manufacturer’s guidelines.
In addition to performing the inspection between supports, rope access teams can safely lift the piping at each of the supports.
This enables the technician access to each contact point for a thorough inspection of the entire line.
Recently, six out of six wharfs whose piping systems were inspected using this hands-on rope access method required immediate attention to some extent, with as high as 42 percent of the areas recorded requiring repairs.
