Optimal Transit Reveals Floating Clean Energy Vessel Designed to Power Coastal Communities
Optimal Transit, a U.S.-based company, has introduced an ambitious floating platform that could reshape how coastal regions access electricity, clean water, and high-performance computing. Known as the Blue Economy VITAL 100 MW Kraaken, the vessel is designed to operate offshore without relying on fuel, land-based infrastructure, or permanent coastal construction.
The Kraaken uses a small waterplane area twin hull design, commonly known as SWATH, which helps improve stability in open water. Combined with a flexible mooring system, the vessel can remain positioned offshore while delivering essential services to land through a quick-disconnect umbilical connection. That system allows power, water, and data to be transferred to shore while also giving the platform the ability to disconnect and relocate within hours if severe weather approaches.
According to Optimal Transit, the 100 MW Kraaken could generate enough clean electricity to support around 32,000 homes. It is also designed to produce nearly 8 million gallons of fresh water per day using vacuum-flash desalination, enough to serve approximately 150,000 people. In addition, the vessel could dedicate about 60 MW of power to AI and data-processing workloads, making it a floating hub for both utilities and computing.
At the center of the platform is Optimal Transit’s proprietary Digital Ocean Thermal system, or DOT. This technology is designed to combine ocean heat with waste heat from computing operations to create continuous electricity. Cold seawater is also used to help regulate temperatures, improving efficiency while reducing the need for conventional cooling systems.
One of the most compelling features of the Kraaken is its mobility. Unlike land-based power plants, desalination facilities, or data centers, the vessel does not require years of permitting, zoning, and construction before it can begin operating. If a coastal area is struck by a hurricane, flood, or other disaster, the platform could potentially be moved into position and help restore electricity, fresh water, and data services within days.
Optimal Transit also envisions multiple Kraaken units working together as an offshore “Sovereign Power Park.” In this arrangement, several vessels could be clustered near a coastline to provide large-scale power and water capacity for an entire city or metropolitan region.
The company estimates that building equivalent infrastructure on land could cost between $750 million and $1.33 billion and take six to ten years to complete. By comparison, a 100 MW Kraaken vessel is projected to cost under $500 million to build, excluding computing hardware. Annual operating expenses are estimated at $10 million to $20 million.
This cost structure could make the floating platform especially attractive for regions where electricity is expensive, unreliable, or heavily dependent on diesel generators. Coastal areas in sub-Saharan Africa, the Pacific Islands, and parts of Asia could be strong candidates for the technology, particularly where demand for clean water and stable power continues to grow.
Optimal Transit is planning several versions of the platform to serve different needs. Smaller 10 MW and 20 MW models would be aimed at lighter workloads and regional use cases, while larger 50 MW and 100 MW vessels would target hyperscale computing, utility-scale power generation, and major desalination needs. The biggest versions are expected to measure around 90 meters long, while smaller variants would be approximately 76 meters.
The company is currently working on engineering designs and plans to move toward larger-scale production once additional financing is secured. If successful, the Kraaken could become a new model for offshore clean energy infrastructure, combining renewable power generation, fresh water production, and AI-ready computing in a single mobile platform.
