Nickel Alloys, Titanium and Stainless Steel Subsea Connections

For the other three types of subsea connections, the primary purpose of the connection method is to create a pressure-tightseal that resists the loads associated with subsea environments. The connection between the sealine and the connection point is generally made after sealine end alignment is complete. The mechanical connectors use either a mandrel or hub style interface, an the actuating tools are hydraulically or mechanically actuated. For deep water all seals experiencing hydrostatic pressure should have bidirectional capability. In the following subsections we discussed several types of sealine connectors that typify the numerous options available.
