The play in six steps

1. 01

   Measure time at anchor

   MA MarineCadastre AIS

   What you pull

   AIS positions at the port's anchorage over the last year: vessel, arrival, departure and days at anchor.

   Why it matters

   Long waits in warm water are when fouling builds. The history shows which vessels wait the most.

   Example

   Long Beach anchorage · 6 vessels from one operator · average 9 days per call

2. 02

   Find the operator

   USCG PSIX

   What you pull

   Vessel records: name, type, size, owner and operator.

   Why it matters

   The operator decides on hull cleaning and pays the fuel bill.

   Example

   6 bulk carriers · same operator · built 2011 to 2016

3. 03

   Build the cleaning schedule

   Your artifact

   What you build

   Each vessel's anchorage history and a cleaning slot during its typical wait, with the fuel cost of a fouled hull as context.

   Why it works

   It fits the work into time that is already lost, which is the easiest yes.

   Example

   6 vessels · next expected calls · cleaning during the wait · no off-hire

4. 04

   Check before you send

   Check the port's rules on in-water cleaning and capture of debris; some ports restrict it. Confirm current operators, since vessels change hands.

5. 05

   Find the vessel operator's technical manager in Glider

   Glider

   Search for

   Technical superintendentTechnical managerFleet managerMarine superintendent

   Why them

   The technical superintendent owns hull condition and fuel performance.

   What you get

   A work email and a direct phone, with the email verified before it goes into a sequence.

6. 06

   Send the evidence, then run the first test

   Your six bulk carriers² averaged nine days at anchor per Long Beach call over the last year.¹ Fouling builds fast in warm water at anchor and costs fuel on the next leg, so I put together the per-vessel history and a cleaning schedule we can run during the wait, with no off-hire.³ Want to see it?

   • Facts from the data (the number is the step)
   • What you built for them
   • One small ask

   Why it works

   It turns lost waiting time into something useful, using data about their own ships.

   First test

   Five operators with long average anchorage at one port.

   Success looks like

   One cleaning contract out of ten operators.

The sample message is hypothetical and its numbers are illustrative. Verify every claim, date and rule before sending.
