Frequently Asked Questions - Cayman Islands


What is OTI’s plan for an OTEC platform in Grand Cayman?
OTI Floating Power PlatformOTI seeks to provide up to 25-MW of renewable wholesale electricity to Caribbean Utilities Company from a set of Floating Power Platforms (FPP) moored off the North Side. The first phase of the project would be the generation of 6.25-MW from a platform that would be permanently moored a little under a mile from shore. Power generated at the facility would be carried to an onshore substation and connected to the island’s CUC grid.

Why did OTEC International choose Grand Cayman?
OTEC International chose the Cayman Islands because it found open and willing partners in a utility (CUC) and a government that want to move away from relying on expensive, imported fossil fuels. Investors have confidence in the Cayman Islands, its stable government and its known legal framework. The Cayman Islands has documented its storm history with precision, making it easier to identify locations where floating platforms can be securely sited and appropriately designed to survive strong storms conditions. And, of course, the geography includes deep water near the shoreline and excellent water temperatures for an OTEC facility.

What is the visual impact of the FPP along the north coast of Grand Cayman?
GCI Offshore ViewVisual impact of the Floating Power Platform (FPP) will be very minimal because the platform will sit just 16 feet above the water line except for a small portion extending 24 feet above water. Its visual impact will be further minimized by a paint scheme that will help it blend in with the surrounding environment.

What are the advantages of using OTEC in the Cayman Islands?
By taking advantage of a renewable resource—the infinite amount of solar energy stored in the ocean’s top layer—the Cayman Islands receives several benefits from adding OTEC to a diverse energy portfolio. Wholesale power will be supplied at a high operating capacity and at prices that are competitive, reliable and much more consistent than what’s found on the volatile fossil fuels market. During the summer when the surface temperature is warmer, OTEC produces more power, just as it’s needed during peak demand for air conditioning. An OTEC floating power platform has a low profile, cabling that is primarily buried underground, and no emissions.

How will the ingestion of marine life into the intake pipes be prevented in the FPP?
The Floating Power Platform (FPP) has been designed with a series of mesh screens over the opening and length of the warm- and cold-water intake pipes to prevent ingestion of small or large marine life.

What impact would natural disasters such as hurricanes have on OTI’s Floating Power Platform?
Because storm history in and around the Cayman Islands has been documented so thoroughly over the years, OTI has thoroughly analyzed the optimal locations for a Floating Power Platform (FPP) and ensure its flexible moorings can help the platform ride out a severe storm. In the event of such a forecast, operations would be shut down and personnel would be moved off the FPP. Operations would resume when the weather improves.

Would an earthquake affect the Floating Power Platforms’s moorings?

The Float Power Platform's mooring spread was designed by a world-renowned mooring systems expert; each of the four corners of the barge platform will be connected to a spread of three mooring lines. The installation method of the permanent mooring system has been designed to survive earthquakes and geological stresses.
