Confidence in every cathodic protection inspection 

SentinelCP

Building on the proven performance of the STR SeaCP system, SentinelCP is STR’s next-generation cathodic protection (CP) inspection system. Featuring a more compact and lightweight design, enhanced software and greater mounting flexibility, it delivers dependable performance while simplifying subsea inspections. 
Cathodic protection inspections, made simple. 
Protecting the integrity of subsea assets starts with reliable cathodic protection inspections. SentinelCP enables operators to accurately assess cathodic protection performance, helping identify corrosion at an early stage so maintenance can be planned before issues become costly failures. 

Building on years of proven operational experience, SentinelCP has been redesigned to deliver greater flexibility, improved usability and a more compact solution for today’s subsea inspection requirements. Designed for deployment across both observation-class and work-class ROVs, SentinelCP combines dependable performance with straightforward operation, giving survey teams everything they need to carry out efficient CP inspections with confidence. 

Whether supporting offshore energy or marine infrastructure projects, SentinelCP delivers reliable results in even the most demanding subsea environments.
