Subsea Trees, Valves and Actuators

OPT TreeOPT’s extensive background in oil field equipment allows for specialized design and analysis of various items; some to solve unique problems. One such example is design of a subsea tree and analysis of its subsequent components. OPT was approached by an equipment supplier to design a wellhead connector, tubing hanger with running tool, and gate valve operator. The resulting wellhead connector interfaces with the popular 18-3/4-inch wellhead systems. The tubing hanger and its running tool are non-orientation with an electrical connection and can land and lock within any of the popular 18-3/4 wellhead systems. The gate valve operator is a fail-safe closed type with ROV override and visual indicator. All components have been integrated into a new subsea tree package. Such design capabilities gives an operator added equipment supply flexibility when completing an existing well.
