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
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.
The team at Seahorse Energy® has experience in the development of critical dry tree production system components. These components range from high pressure drilling risers to tieback connectors. Also unique to Seahorse Energy®, the team has experience in the specification, design, and manufacturing of carbon-fiber production risers, drilling risers, and choke and kill lines. The team also has experience designing stress joints made of both steel and titanium.
Having the right people offshore makes all the difference in the world. Seahorse Energy® field service and engineering personnel have the experience to make it happen offshore — safely and reliably. Whether it is running new equipment or repeat equipment, our team is ready to support you. We have experience organizing and leading WOPs of many varieties which is key to safe and cost efficient offshore operations.
The Seahorse Energy® team has experience supporting many types of offshore operations including intervention. Subsea interventions require experienced people that can think quick on their feet, but remain disciplined in approach under all situations. The Seahorse Energy® team has this experience and is ready to assist you during the planning stage and on your next offshore intervention.
Drilling operations are key to successful subsea operations in the short and long term. The Seahorse Energy® team has decades of drilling and pressure containment experience. This experience ranges from both low and high pressure drilling riser systems (diverters, telescopic joints, choke and kill lines, aux lines, risers joints and connectors, etc.). This experience includes both conventional materials and carbon fiber composites.
Keeping a subsea system profitable usually requires an occasional intervention to improve productivity. Seahorse Energy® has a broad range of experience in engineering and manufacturing of intervention equipment. Recent experience led to the deepest riser-less intervention in the world. Some of this experience includes:
Having the proper ROV tooling and technology is essential for a successful subsea development. Seahorse Energy® has significant experience designing and building ROV tooling and equipment that do remarkable things subsea. We can also design and manufacture very quickly new solutions for those “unexpected” situations where innovation and speed is required to meet an unplanned challenge. A few examples are:
Subsea trees come in many forms, sizes, and capabilities. At Seahorse Energy®, we understand and have the experience to design, manufacture, and integrate subsea production components. We have experience in HPHT applications, as the engineers at Seahorse Energy® were involved in the implementation of the world’s first 15K horizontal tree systems years ago. Seahorse Energy® has critical metal-to-metal seal design, analysis, and testing experience for high-pressure and high-temperature applications. Seahorse Energy® personnel have pioneering developmental and implementation experience in some of the first 20KSI seal systems for subsea use. We have the ability to develop testing and SIT procedures and/or manage your entire SIT.
The team at Seahorse Energy® has a vast amount of experience in developing, manufacturing, and installing subsea jumper systems and the related connector systems. We can also manage your jumper metrology, SITs, and installations. We have experience in developing and manufacturing the following connection systems:
At the heart of a subsea production system is the ability to reliably and safely connect the various infrastructures as the field architecture progresses. The Seahorse team has the experience to design, manage, and manufacture subsea templates, manifolds, horizontal and vertical connection systems, manifold piping and valving. We also have experience developing FAT/SIT procedures and managing the testing.
