JIP ROLL

FPSO ROLL JIP

Dynamic effects

Hydrostatic effect

Frozen

WHY ?

• Large roll experienced on several FPSO’s in various areas

resulting in delay and production loss

• Prediction methods use empirical data for ships not valid

for FPSO’s

WHAT?

• Reduction of roll motion’s of FPSO’s:

In-situ behaviour

Prediction by model tests and numerically

Control of roll motion in design and operation
