As offshore exploration and production of oil and gas moves into water depths up to 10,000 ft and beyond, the demand for buoyancy on deep water production and drilling risers is increasing at near exponential rates. This demand is generally driven by the need to reduce riser top tensile stresses and floating vessel connection loads. However, buoyancy also significantly increases the riser drag-to-weight ratio, and this in turn greatly affects riser dynamic response. In many cases, the benefits to be gained by using buoyancy to reduce static top tensions can largely be wiped out by detrimental dynamic response effects. It is clear that the exact role of buoyancy in deep water riser configuration design needs to be established and this paper explores some important issues on this matter.
