Saipem has contracted BMT Scientific Marine Services (BMT) a subsidiary of BMT Group Ltd,  to provide riser monitoring systems for two Free Standing Risers (FSHRs) and four Steel Lazy Wave Risers (SLWRs) for the Sapinhoá Norte and Cernambi Sul pre-salt fields offshore Brazil.

These systems will monitor the integrity of these risers by measuring strains, motions, attitude, and position of submerged portions of the riser strings. Each FSHR system will include BMT’s patent pending ROV-Serviceable Strain Sensor Assembly which allows users to service or replace individual sensors by ROV. BMT’s patented polypropylene welded attachment scheme for attaching strain sensors to submerged, insulated pipes will be employed on the SLWRs.

BMT brings valuable experience to this project having supplied five Free Standing Riser Integrity Monitoring Systems since 2007 covering a total of twelve riser towers, and two SCR monitoring Systems.  The award complements BMT’s extensive order book that includes integrity monitoring systems for three riser towers in West Africa and two in Brazil as well as for eight SCR’s in Brazil. In addition, BMT has in various stages of delivery six Marine Integrity Monitoring Systems for Floating Production Units.
