Umbilical Industry Experience and Trends

Many offshore projects require the consideration of greater depths, longer umbilicals and more control functions than those common in the past. Further, most oil companies are striving to reduce the time required to complete such developments. As a result, the selection of umbilicals has become more critical as many factors such as performance, fluid compatibility, impact on interfaces, ease of deployment, etc. must be considered during the selection process.

There are two continuing trends in the offshore umbilical industry:

(1) Oil production in deeper and deeper waters;

(2) The desire to perform subsea Processing; Subsea field development moves to deeper and deeper water depths. This requires higher and higher demands on the umbilical systems to ensure operational integrity throughout the lifetime of the fields.

The need for feeding of electrical power to subsea equipment, such as subsea pumps, is also increasing because subsea processing technology is considered more and more these years. Both these trends affect the umbilical design that the weaker cross-section components must be able to withstand the larger forces and elongations. Besides, the cross-section must include high voltage power elements.
