Pulse, an Acteon company, has designed, manufactured and installed a powerful motion and strain monitoring system to verify the design of the first lazy-wave steel riser system to be installed in the Gulf of Mexico.

The monitoring program at Anadarko’s Constitution spar in the Green Canyon area of the Gulf of Mexico started in 2012 and has enabled validation of the riser design against analytical models and verified riser system integrity during a hurricane event. Pulse was selected because of its understanding of the technical challenges and ability to meet a very tight deadline: the entire monitoring system was designed, manufactured and delivered in less than six weeks.

The system relies on Pulse’s proprietary INTEGRI™ sensors, which are located in clusters in the two most critical locations of the riser: the hang-off and touchdown zones. INTEGRIpod motion sensors record three-axis acceleration and two-plane angular rate. Data are recorded locally and downloaded for post-processing after sensor retrieval. INTEGRIstick stand-alone strain sensors measure the change in riser curvature in two planes.
