Abstract
The invention relates to systems for producing oil and hydrocarbons in general, in deep water, using subsea wells and apparatus which are interconnected in a drainage and production system. In this context, the invention relates to a mandrel multiplying device (1a, 1b, 1c, 1d, 1e, 1f) suitable for providing additional points between pieces of subsea apparatus, the device comprising a connector (2) for coupling to a mandrel of a subsea apparatus (8, 9), and at least two mandrels (3, 4, 5) suitable for providing points for connection to subsea lines (J1, J1′, J1″, J2, R1, R2, A1, A2, A3) which are connected to other pieces of subsea apparatus (8, 9) or to a production unit (13).
Claims16
A mandrel multiplying device for subsea oil production equipment, wherein the device comprises:
- a connector for removably coupling with one mandrel of a subsea equipment device;
- at least two mandrels to provide connection points between the subsea equipment device and subsea pipes interconnected to other subsea equipment or to a production unit;
- and
- a conduit connecting the connector and the at least two mandrels,
- wherein a first portion of the conduit is disposed substantially horizontal between the at least two mandrels, and
- wherein when the connector is coupled with the one mandrel of the subsea equipment device, the at least two mandrels of the mandrel multiplying device replace the one mandrel of the subsea equipment device thereby increasing a number of connection points associated with the subsea equipment device.
A mandrel multiplying device for a subsea oil production equipment, wherein the device comprises:
- a connector for coupling with a subsea equipment mandrel;
- at least two mandrels to provide connection points with subsea pipes interconnected to other subsea equipment or to a production unit;
- and
- a conduit connecting the connector and the at least two mandrels,
- wherein a first portion of the conduit is disposed substantially horizontal between the at least two mandrels, and
- wherein the mandrel multiplying device allows a pig to pass within the conduit between a first mandrel of the at least two mandrels and the connector, between a second mandrel of the at least two mandrels and the connector, and also between a third mandrel of the at least two mandrels and the connector.
