Title: The Innovative Contributions of Darrell Raymond Catte

Introduction

Darrell Raymond Catte is a notable inventor based in Dhahran, Saudi Arabia. He has made significant contributions to the field of cathodic protection technology, holding a total of 2 patents. His work focuses on developing advanced methods and apparatuses for monitoring and enhancing the protection of structures from corrosion.

Latest Patents

One of Catte's latest patents is the "Cathodic protection assessment probe." This innovative apparatus and method are designed for monitoring the cathodic protection of a protected object. The probe consists of five segments arranged in series, with a system that includes a power supply to impress current onto the protected object. An anode is also part of the system, connected to the power supply. The third and fifth segments are in electrical communication through a frangible connection that gradually corrodes to isolate them electrically. The second segment acts as a permanent isolator, positioned between the first and third segments. This design allows for accurate measurement of the potential difference between the third and first segments, yielding a value for object polarization that is free from IR error.

Another significant patent by Catte is the "Axial current meter for in-situ continuous monitoring of corrosion and cathodic protection current." This invention features first and second axial current meters (ACM) that are mechanically connected to a well casing above and below a corrosive zone. A master axial current meter (MACM) is connected to the casing at the earth's surface. The MACM periodically obtains measurements of axial current from the ACMs to determine the appropriate amount of cathodic protection current needed to prevent corrosion.
