Automate Fleet Status with a workflow

A workflow runs your methods as one process, with nobody at the screen. A schedule or a call from your own system starts it, the steps run in order, and the result arrives in your inbox or in the systems you already use.

• Surveys and audits due within 30 days, every Monday

  Build this

  Starts

  Every Monday at 7:00

  Step 1

  Get the Survey Schedule for My Fleet with only soon overdue items.

  Step 2

  Group the surveys and audits by vessel.

  Step 3

  Email you the list with survey or audit, type and due date.

• New Conditions of Class and memoranda, posted to your system

  Build this

  Starts

  Every weekday at 8:00

  Step 1

  For each vessel you name, list the follow-up items on its Follow-up tab.

  Step 2

  Keep the CC and MO items that were not there on the last run.

  Step 3

  Post each one, with vessel, code, text and due date, to your webhook.

• Newly issued certificates, logged in your document system

  Build this

  Starts

  Every day at 18:00

  Step 1

  For each vessel you name, list the certificates and reports on its Documents tab.

  Step 2

  Keep the documents that were not there on the last run.

  Step 3

  Post vessel, document name, type and validity date to your webhook.

You can run a workflow by hand on every plan, Free included. Schedules and webhook triggers come with the paid plans, from $29 a month.

Once built, one call from your code

Once you have built a method, it is one POST to /v1/runs from your backend, or a tool an AI agent calls over MCP. This is what “Get the survey schedule” would look like.

curl https://api.fous.com/v1/runs \
  -H "Authorization: Bearer $FOUS_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "method": "maritime.dnv.com/get_survey_schedule",
    "input": {
      "vessel_group": "My Fleet",
      "only_soon_overdue": true
    }
  }'

{
  "status": "completed",
  "data": {
    "vessel_group": "My Fleet",
    "items": [
      {
        "vessel": "Acme Horizon",
        "name": "Annual survey, hull",
        "kind": "survey",
        "category": "Class",
        "type": "Annual",
        "due_date": "2026-12-03"
      }
    ],
    "count": 1
  }
}

An example with invented data, not a ready-made endpoint. The method exists in your organization once you build it, and its name, inputs and fields follow your request.

Fleet Status’s own options

DNV offers a Class Status API that returns class status information and certificate documents, as JSON or XML. It needs a separate API contract signed with DNV, after which DNV sets up the API user. Fleet Status itself is free for owners and managers of vessels with DNV class or management system services, and its survey and vessel tables export to Excel.

Signing in to Fleet Status

Fleet Status opens from My Services in Veracity or directly at maritime.dnv.com/fleet with your email address and password. Your company administrator grants Fleet Status and access to each vessel. With Fous you sign in once through that same sign-in with your own account: the login is sealed with AES-256, and an expired session is signed back in.

Worth knowing

Some due dates are only indicative

For vessels DNV cannot issue full-term certificates for, Fleet Status shows survey due dates as indicative, and they may be incorrect. A workflow passes on those same dates.

You see only the vessels you were given

Fleet Status needs an active service subscription and access to each vessel, set by your company administrator. A method sees the same vessels as the account it signs in with.

Class Status report comes in two versions

The Class Status report downloads either With Memorandum to Owner or Without Memorandum to Owner. Decide which one goes to charterers or vetting before automating the hand-over.

Set the PO number before Scheduled

When a PO number is Required, it can be updated until the survey request status is Scheduled. DNV notes that adjusting an invoice after it is issued may lead to a handling fee.
