Revenue model

1. Government Ship Management Contracts: Long-term, multi-year fixed-price contracts with U.S. federal agencies (U.S. Navy Military Sealift Command and U.S. Department of Transportation/MARAD) covering crewing, maintenance, repair, and operational management of government-owned vessels. Example contract value: Watson Class LMSR award with $220,275,409 total estimated amount over a 1-year firm + 4 one-year option structure. Five-year MARAD General Agency Agreement signed September 2020.
2. Leasing and Chartering Brokerage: Revenue from ship chartering and leasing services; OSI locates vessels via a worldwide network of brokers and owners, and operates bareboat-chartered ships on a turnkey basis.
3. Marine Project Management and Construction Services: Fee-based project management for vessel design, conversion, and shipbuilding — including design review, construction planning and supervision, schedule/cost management, and warranty performance management.
4. Repair, Dry-Docking and Maintenance Services: Revenue from vessel overhauls, scheduled regulatory drydockings, and worldwide maintenance performed by OSI engineers across shipyards in many countries.

• Bernhard Schulte Shipmanagement: Global third-party ship manager offering crew management, technical management, and newbuilding supervision comparable to OSI's ship management and project management service lines, though focused on commercial tonnage.
• Anglo-Eastern Ship Management: Major independent ship manager providing technical management and crewing services worldwide, comparable to OSI's core ship management offering for ocean-going vessels but at much larger fleet scale.
• Teekay Corporation: Publicly listed marine energy and tanker services company with shuttle tanker and offshore vessel operations; overlaps with OSI's petroleum vessel heritage and GoMAX 550 shuttle tanker design rights but at materially greater scale.
