Bluewater builds 200 MW campuses inside proven offshore concrete towers —
cooled by the sea, powered from shore through rights that already exist —
and maintained by technicians who take an elevator, not a submarine.

The problem
The markets that need capacity most can no longer build it
Northern Virginia, Santa Clara, Phoenix, Atlanta — the grid queues run two to four years,
the land is gone, the water is contested, and the neighbors are organized.
Capital is available; buildable megawatts are not.
Twenty-five miles offshore sits a site nobody is fighting over — a 3-acre seabed lease,
50–54 °F cooling in every season, no neighbors within earshot, and no interconnection queue.
2–4 yr
Grid queues
Interconnection waits in the major metros now exceed typical build schedules — power, not capital, sets the pace.
100+ ac
Land per campus
A 200 MW campus needs contested metro land, rezoning, and years of hearings. Offshore, the footprint is a 3-acre seabed lease.
0.5–1B gal
Water per year
Evaporative cooling at this scale consumes a small city’s water. The ocean takes the same heat without losing a gallon.
85 dB
The noise fight
Cooling-plant noise is now a leading cause of data-center opposition. At sea, the nearest bedroom window is 25 miles away.
Reference project · first vessel
A 50 MW floating AI campus — the barge is the building, the ocean is the heat sink
The near-term product is a jetty-moored, non-propelled heavy barge: ten identical
5 MW infrastructure blocks, direct-to-chip liquid cooling, and seawater heat
rejection through isolated titanium exchangers. Bluewater delivers powered, cooled,
secure halls. Customers bring the servers and GPUs.
The 200 MW concrete tower remains the campus-scale platform; this vessel is how
we put megawatts in the water first.
Five decks, top to bottom: electrical topside, two 25 MW IT halls, mechanical plant, seawater and ballast. Heavy compute stays low in the hull.Base case is jetty-moored on existing high-capacity power and fiber — not a greenfield “anywhere” claim.Upper and lower IT halls share the same 5 MW module geometry. Direct-to-chip liquid cooling; no raised floor in the base design.Topside is electrical and service only. Primary heat rejection is below deck. No chiller farm, no cooling towers.

Four Gullfaks-class concrete shafts — 98 ft across at the base, 46 ft at the top —
carry the entire 200 MW from day one. Halls are sealed in dry nitrogen; a pressurized
core with passenger and 5-ton freight lifts keeps every rack an elevator ride away.

From the topsides lobby, a passenger lift and a 5-ton freight lift run the full height of

Step off at any deck: liquid-cooled racks ring the elevator core, denser as the shaft
widens toward the base — from roughly 2,600 sq ft per deck at the top to
4,800 sq ft at the bottom. Cold plates take the heat straight to the risers you
see running the height of the shaft.

Two doors between air and nitrogen
The halls beyond the core are sealed in dry nitrogen — no oxygen, so no fire, no corrosion,
no dust. On planned maintenance days a technician swings through the airlock with a
breathing set; the rest of the year the racks run untouched, and fail roughly eight times
less often for it.

At the bottom of the shaft, seawater pumps and hull heat exchangers move the tower’s
heat into 50–54 °F ocean — the machinery that replaces an entire chiller yard on land.
The freight lift serves this deck too: every pump is swappable without a marine operation.

Technology
Assembled, not invented
Every element of a Bluewater tower has decades of service history in another industry.
Our work — and our patent-pending system — is the integration.
01 / STRUCTURE
Condeep-class concrete tower
A 525 ft gravity-based structure descended from ~30 North Sea platforms — slip-formed
in a dry dock, towed to site floating, ballasted down in a season. Certified under existing
DNV offshore-concrete rules. 75–100 year design life.
02 / ATMOSPHERE
Sealed nitrogen halls
No oxygen means no fire, no corrosion, no dust — the regime Microsoft’s Project Natick
showed cuts hardware failures roughly eightfold. Technicians work from a one-atmosphere
core and enter halls through airlocks on planned maintenance days.
03 / ACCESS
An elevator, not a submarine
Passenger and 5-ton freight lifts connect the surface deck to every data deck at ordinary
atmospheric pressure. Any rack, in minutes, in street clothes — no divers, no decompression,
no marine operation to swap a server.
04 / POWER
800 VDC, megawatt racks
High-voltage DC distribution runs the halls at rack densities today’s grid-tied
buildings can’t reach — ready for 120 kW AI racks now and 1 MW-class racks
over the structure’s life. Power arrives from shore; the halls are
generation-agnostic if a future onsite source is ever added.
Heritage · Proof of scale
These shafts have been built before — more than twenty times
Gullfaks A’s four concrete shafts rising out of Gandsfjorden, Norway, in 1984–85 —
the same four-shaft, 98 ft-base configuration Bluewater outfits as data halls.
Slip-formed around the clock by 1,400 hydraulic jacks, the finished substructure was
towed to sea floating and set down on the seabed, where it has operated since 1986.
Nothing about the structure is new; only the payload is.
Four completed shafts under tow — the tugboats alongside give the scale. Each shaft is wide enough to hold the fifteen data decks of one Bluewater module.The slip-form deck from above — count the workers. Every data deck we outfit spans this circle.Inside one shaft during construction — the volume that becomes fifteen decks of server halls.

Cooling
The ocean is the chiller
Closed-loop liquid cooling carries heat from cold plate to hull heat exchanger; the sea
does the rest. At 100–300 ft the water holds 50–54 °F every hour of every
year — no heat waves, no derating, no evaporation.
Supply reaches the racks at ≈64 °F, returns at ≈95 °F, and leaves
through the hull with a thermal plume that disperses within yards. The result is a
1.05 PUE in any climate — and a data center that is quiet on both sides of the
waterline. No cooling towers or rooftop fans for neighbors who don’t exist; below
the surface, Microsoft’s undersea deployment measured its sealed hull as quieter
than the snapping shrimp around it.
Power
Shore power first — no interconnection queue
Day one runs on an existing shore interconnection. The structure, halls, and cooling
stay the same if a future onsite generation path is ever pursued — that decision waits
for FID, licensing, and real economics, not the Series A story.
Land on grid rights that already exist. The tower’s
220 kV corridor connects at a retired coastal plant — berths like San Pedro and
San Onofre — so day-one capital is ≈$2.3B and there is no multi-year interconnection
queue. Topsides hold the GIS and transformers; the architecture stays open to later
generation only if it clears licensing and cost.

Pile drives, hammer blows
The base floats out and ballasts down — none of the piling noise that stalls offshore wind. In service the sealed hull is quieter than the seafloor’s own snapping shrimp (Natick, measured), with hydrophones keeping watch.

Who we are
Nobody has built this project. Everyone on this bench has built its parts.
Bluewater is a first-of-a-kind combination of proven pieces — so the team is drawn from the
people who delivered each piece: North Sea concrete platforms, hyperscale data centers,
large-scale power, and multi-billion-dollar infrastructure financings.
Founder & Developer
20+ years founding and developing projects in the defense and energy sectors
The founder’s role: identify the convergence, control the sites and permits, hold the
capital plan together — and recruit the people who have each built their piece of it before.
Offshore structures
Senior alumni of the Condeep design-and-build lineage: gravity-base design, marine construction, DNV classification.
Hyperscale data centers
Former capacity-delivery executives from the largest cloud operators, with multiple campuses delivered end to end.
Power & transmission
Utility leadership and developers of large generation and transmission — the people who land interconnection and keep megawatts firm.
Project finance
Veterans of multi-billion-dollar infrastructure financings, including non-recourse debt raised from infrastructure lenders.
Permitting & government
Former federal offshore-permitting officials and environmental leads — the people who have run the reviews we will file.
First-option design partner: Dr.techn. Olav Olsen (Artelia) — the Norwegian firm behind the
original Condeep platforms — for front-end engineering. Advisory and executive seats are
announced as they sign; the full roster is disclosed in the investor data room.
Investors & partners
Buildable megawatts are the scarcest asset in computing.
Bluewater is raising development capital to de-risk the 50 MW reference vessel — naval
architecture, class, hull, interconnect, and an anchor customer — and to keep FEED moving
on the 200 MW concrete campus. A non-confidential teaser is available on request; the full
deck and data room follow for qualified investors.
