Subsea Dispersant System
In the event of a deepwater blowout multiple problems must be assessed and solved in a short period of time. One important effort is to inject dispersant fluid at the source of the leak. Seahorse Energy® was contracted to design, manufacture and deliver 1,500’ long hose dispersant systems. In the event of a blowout, a hose skid is set on the seabed such that the dispersant fluid vessel can be kept at a safe distance. ROV’s are used to connect the dispersant hose to a coiled tubing manifold hung from the vessel. ROV’s are then used to deploy the dispersant hose from the “figure 8” skid to the leak where dispersant fluid can be injected.
Vertical Hydraulic Stab Tool
On the Yukon project, there was a desire to unlock the tubing head with the tree still installed (vertical tree system with the tree installed on a tubing head). The original design of the tubing head requires a guidebase-type running tool to interface with a vertical hydraulic mandrel in the “corner” of the tubing head frame. With the tree in place, this was not possible with the existing running tool. Seahorse designed a short, light-weight ROV tool that could be flown onto the vertical mandrel, locked in place, and able to mechanically establish communication with the hydraulic controls. The Vertical Hydraulic Stab Tool was designed, manufactured and delivered in 9 weeks.
ROV panels are a critical aspect of any intervention. They are the interface between the subsea equipment and the ROV, providing a means of functioning valves, pressure testing, establishing hydraulic access, and more. Seahorse Energy® designs, manufactures, plumbs and tests all of the ROV panels for our intervention equipment.
