Sonardyne’s Marine Riser Angle Monitoring System (MRAMS) is a highly accurate, cable-free solution for measuring the differential angle of a marine riser, BOP assembly and vessel’s position relative to it.

Developed from field proven components, the system is based on the integration of Sonardyne’s USBL acoustic positioning technology and BOP-mounted transponders fitted with high resolution inclinometers. This provides clear and unambiguous data on the vessel’s position and riser angle status.
