Serviced in daylight,
not at 400 metres.
The term
Negative-lift servicing
Servicing where the equipment returns to the surface and nothing is lifted.
Down there it works.
Up here it is serviced.

01
On the seabed
Plant & equipment do the work at depth.
02
It returns
When a module needs service, it returns to the surface on its own.
03
Serviced in daylight
Crews service at surface or on land, in daylight.
04
Towed in
A tug can tow modules to/from a land base. Spares take their place.
A tug, not a construction vessel.

One platform. Any seafloor equipment.
Modular
Plant & Equipment modules, one spare in rotation.
One at a time
Each module comes up on its own. The rest keep working.
Any seafloor equipment
Desalination first. Minerals, oil and gas, data centre cooling and marine diamonds next.
Removable by design.
Sited on bare sand.
At this depth the seafloor is largely featureless sand, away from the reefs and kelp where marine life concentrates.
Serviced on the surface or land.
Maintenance happens at the water’s surface or a land base.
Nothing is left behind.
Whatever goes on the seafloor can come off it, including the platform itself.
Patent-pending.
