description An apparatus and a method for extending subsea hydrocarbon flowlines from an initial installation on a template/manifold system to later drilled subsea wells. The extension utilizes a pigging valve assembly which completes a flow path to allow for line cleaning or pigging and is modified by adding a curved flowline connector adaptor to extend the subsea flowlines. The apparatus and method minimizes the amount of equipment that must be pre-installed to provide such flexibility, thus facilitating the ability to defer incremental development decisions.
