Meanwhile, the harsh underwater environment — including high pressure, corrosive saltwater, and ? uctuating tempera- tures — can cause wear and tear, increasing the likelihood of equipment failing. Additionally, umbilicals often lack the ? ex- ibility needed for dynamic or modular systems, limiting their suitability for autonomous, deeper, or more remote operations.

In oil? eld operations, umbilicals must deliver hydraulic ? u- ids, chemicals, and power to equipment stretched across vast underwater landscapes. During these projects, umbilicals can be vulnerable to clogs or conductor breaks and power limita- tions, particularly when handling signi? cant movement stress or peak electrical demands. Also, as umbilicals get longer for deeper or more remote locations, since electrical resistance increases proportional to the length of a conductor, the gauge thickness of the power conductors in the longer umbilicals must increase to compensate for the increased length and de- liver the same power to the endpoint of the longer umbilical.

This makes the entire umbilical thicker, heavier, more expen- sive, and harder for operations to handle.
