Abstract
A subsea connector system for connecting the lower end of a structural core of a marine riser to a base which has been preset on the marine bottom. The box member of the connector system forms an integral part of a tapered section which, in turn, forms the lower end of the riser. The connector system, in a preferred embodiment, incudes a self-contained source of hydraulic fluid under pressure which actuates the connector to a locked position upon command. The connector also includes a back-up means for remotely locking the connector and three separate means for remotely unlocking the connector.
