RIO DE JANEIRO, Brazil –Fugro introduced its Optima riser operations planning and management system today at the IADC International Deepwater Drilling Conference in Rio de Janeiro.
The system collects data in real time to predict riser behavior under existing metocean and drilling conditions. Optima can acquire data on vessel position, tensioner activity, water current, sea state, BOP pressure, mud weight, and hookload. Using finite element and other analyses, the system can indicate the operating envelope relative to flex joint angles or other selected parameters and sound alarms if pre-set limits are exceeded.
In particular, Optima can monitor selectively the riser joints experiencing the most fatigue, said Paul Stevenson, regional manager, Global Environmental & Ocean Services, for Fugro. It accommodates scenarios and planning for drilling and standby operations, drift-off, riser deployment and retrieval, dual-activity operations, and more
