Perdido
The Perdido development is a milestone in subsea engineering. The spar is floating 200 miles off the Texas coast in a staggering 7800 feet of water. Some portions of the subsea field are located 9800 feet below the surface.
We worked closely with our client to develop 14 subsea sleds comprised of 12 unique structures. All of the sleds are now installed on the ocean floor. These structures control the flow of oil as well as injecting the wells with water.
Perdido Sleds
Once it was time to deliver the sleds, we developed barge load out diagrams. Since the crane on site was too small to simply lift the sleds onto the barge, we crafted an inexpensive solution to get the sleds in place using a combination of Hillman Rollers and lifting jacks.

Additionally, our engineers helped develop a unique solution to tie the Perdido oil field into the existing oil export line in the Gulf of Mexico. The structure is referred to as the Connection Foundation. This submersible structure was created to be slightly buoyant during the installation. This allows the Connection Foundation’s installation process to be tightly controlled. Below you can see the 3d design model as well as the finished product.
