The large bore hot stab system provides a fluid connection method for high-flow, low-pressure applications.

The system is currently available can be used for transferring typical subsea fluids, including hydraulic oil and corrosion inhibitors. The female receptacle is attached to a subsea structure prior to deployment, connected by a standard API flange, Oceaneering Grayloc® hub, or welded directly to the host pipe work.

The female receptacle can be configured for access from both ends to improve functionality. If required, a dummy plug can be installed in the receptacle to protect the sealing surfaces and limit contamination of the system when not mated with the male hot stab.

The male hot stab is ROV-installable and is typically connected to an ROV mounted injection or pumping skid or a subsea or surface fluid supply. The male hot stab locks into the female receptacle for positive engagement.
