The short version

  • Each has a real cost: Danaos sales, implementation and support are concentrated in Greece and Cyprus, so an owner elsewhere gets a thinner local bench and has to rely on remote support across time zones.; Sea Machines requires hardware fitted to the vessel; the autonomy systems are retrofits or new build installations rather than a software purchase
  • They diverge on capability: Danaos covers Planned maintenance, Sea Machines covers Autonomous control.
  • Prices and features above were last checked on 30 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Danaos

  • Sales, implementation and support are concentrated in Greece and Cyprus, so an owner elsewhere gets a thinner local bench and has to rely on remote support across time zones.
  • The suite is configuration-heavy, and a superintendent generally cannot change a maintenance form or approval route without vendor involvement, which turns small changes into chargeable requests.
  • The architecture is traditional, with vessel-side installations replicating to shore, so the browser experience trails newer cloud entrants and IT carries software to maintain on every ship.
  • Public documentation and product information are sparse, so a buyer cannot evaluate the product independently and is dependent on vendor demonstrations and reference calls.
  • Because everything shares one database, partial adoption gives away most of the benefit and replacing a single module later means unpicking the whole suite rather than swapping a component.

Sea Machines

  • Requires hardware fitted to the vessel; the autonomy systems are retrofits or new build installations rather than a software purchase
  • Targeted at vessels from 10 to 300 ft, so it does not address the largest commercial tonnage
  • Pricing is not published and is arranged directly with the vendor
  • The SM300-NG is the class-approved unit, so the cheaper SM300-SP does not carry the same approval

Answered from the vendors’ own pages

Danaos: Is this the same company as the listed shipowner Danaos Corporation?

No. Danaos Management Consultants is the software business and a separate entity, although the names are shared and both are based in Piraeus.

Sea Machines: How much does Sea Machines cost?

Pricing is not published. Sea Machines requires customers to contact their sales team directly through the Contact Us link on their website for pricing quotes tailored to specific products and use cases.

Danaos: Does it run on board with poor connectivity?

Yes. Vessels run local installations that replicate to shore, which is a deliberate design choice for constrained satellite links.

Sea Machines: What is the pricing model for Sea Machines products?

Sea Machines offers autonomy systems and software solutions for maritime vessels. Pricing is determined on a per-product basis through direct sales consultation rather than published subscription tiers.

Source
Danaos: Can I license only the planned maintenance module?

Technically yes, but the value comes from the shared database linking maintenance, purchasing and budgets, so partial adoption is uncommon.

Danaos: Is pricing published?

No. Everything is quoted by fleet size and by the modules licensed.
