Trifold solar panel

A method of producing an umbilical includes providing an elongate flat metal strip, providing an elongate service carrier, encasing the service carrier in an insulation that is strain tolerant and high temperature tolerant, forming the metal strip into a tube shape around the insulated service carrier, and thereafter welding the edges of the metal strip to form a tube surrounding the insulated service carrier. The method may further comprise coiling the umbilical onto a spool. Such an umbilical may be useful for carrying fluids, power, control signals, or the like into a well.

Coiled umbilical tubing

Systems and methods for the prevention or dissolution of hydrates in an undersea well. One example system includes a submersible isolation bell for capturing effluent being exhausted from the well, and an umbilical. A power cable supplies electric power to the submersible isolation bell, for example for heating of the interior of the submersible isolation bell to prevent or discourage the formation of methane hydrates and the precipitation of other byproducts. Diluents may be supplied to the submersible isolation bell to further discourage the formation of hydrates and precipitation of other byproducts. The diluents may be heated locally at the submersible isolation bell, using electric power supplied by the power cable. A conformable seal may substantially seal the submersible isolation bell to a riser or other structure at the wellhead.

Thermal hydrate preventer

Methods are provided of producing a heater cable. An electrical conductor is coated with a preceramic resin. At least a portion of the coated electrical conductor is deployed into a operational location. The preceramic resin is pyrolyzed while the portion of the coated electrical conductor is in the operational location to convert the preceramic resin into a ceramic insulator disposed to electrically insulate the electrical conductor from the sheath.
