Welaptega Chain Angle Tool (CAT)

The Chain Angle Tool (CAT) is an ROV-deployed digital inclinometer, ideal for inclination measurement operations of mooring chains or other subsea infrastructure. The CAT is used to verify chain tension and load sharing between lines; an essential element of in-service integrity management and Class UWILD surveys.
