THE LANG MULTI-PURPOSE SEMI-SUBMERSIBLE
REAL ESTATE.
IN THE OCEAN.
A standardized offshore infrastructure platform designed to be leased, configured and redeployed across multiple industries.
01 / WHY
Every offshore project starts by reinventing the platform.
That means years of engineering, complex fabrication, expensive one-off construction and an asset designed around a single mission. Craig Lang took a different view: simplify the foundation, standardize what can be standardized, and let the mission change without rebuilding the host.
They worked. Just.
02 / THE PLATFORM
Keep it simple.
Four large square columns. A continuous submerged ring pontoon. A large, uninterrupted deck. Flat-panel, box-girder construction. No unnecessary structural forest.

Own the platform. Lease the deck. Redeploy the asset.
MILC — the MPSS Infrastructure Leasing Company — is designed to own standardized hulls and dry-lease them to operators. The lessee controls the topsides and operations. MILC provides the floating asset.
Lease first→Finance the hull→Build→Redeploy
The commercial edge is capital efficiency: a simpler hull architecture designed for repeatable fabrication, not a premium day-rate justified by excessive build cost.
04 / MULTIPLE MISSIONS
The platform is the product. Applications are the tenants.
Deepwater production
Heavy topsides and riser integration on a low-motion host.
Floating power
HVDC, grid support and offshore power-island applications.
Floating wind
Large-turbine support, shared infrastructure and cable-risk reduction.
Water & utilities
Desalination, treatment, resilience and remote utility capacity.
Data infrastructure
Stable offshore space for power-dense compute and cooling systems.
Future industries
Hydrogen, CCS, aquaculture, logistics and missions not yet defined.
05 / THE PROOF
Evidence before marketing.
MPSS was examined through independent engineering, model testing, classification review and commercial studies. The design is not being introduced from a blank page.
All supporting evidence is available upon request.
06 / THE ASK
Fund the work that gets MPSS-1 to contract.
Seaways is seeking development capital and strategic partners to complete the next bankable milestones:
- Current class-society engagement
- Updated FEED and design-basis confirmation
- Independent fabrication pricing and schedule
- Anchor-lessee development and lease documentation
- Project-finance preparation for the first hull
