SOUND FAMILIAR?
Counting weeks on your fingers to figure out when you're home
Spreadsheets that break every time the crew change moves
Calendar apps that don't understand "14 on, 14 off"
Missing your kid's birthday because you miscalculated
That constant low-grade stress of never quite knowing your year
YOU SHOULDN'T NEED A SPREADSHEET
TO KNOW WHEN YOU'RE HOME.
THERE'S A BETTER WAY.
OffshoreMate builds your entire rotation year from two simple inputs:
THAT'S IT.
In about 30 seconds, you get a clean, color-coded calendar showing every work period and every off period for the whole year. You can see at a glance when you're offshore, when you're home, and exactly when each crew change happens.
Export it to your phone. Share it with your family. Print it out and stick it on the fridge. Update it whenever your schedule shifts.
No signup. No spreadsheet formulas. No guessing.
JUST CLARITY.
WHY OFFSHOREMATE?
HOW DO I CREATE MY
ROTATION CALENDAR?
PICK YOUR PATTERN
Choose from 14/14, 14/21, 21/21, 28/28 — or set a completely custom cycle if your rotation doesn't fit the standard options.
ENTER YOUR CREW CHANGE DATE
This anchors your entire calendar. Everything flows from here.
GENERATE YOUR YEAR
Instantly see every work period and off period, color-coded for clarity. Crew change dates are marked so you always know exactly when you're traveling.
EXPORT OR SHARE
Sync directly to Google Calendar, Apple Calendar, or Outlook. Or download as a PDF to print or share with family.
UPDATE ANYTIME
Crew change moved? Just update the date and regenerate. Takes about 10 seconds.
The whole process takes
LESS TIME THAN MAKING A COFFEE.
EVERYTHING YOU NEED.
NOTHING YOU DON'T.
SEE YOUR WHOLE YEAR AT ONCE
No more flipping through months or counting on your fingers. Your full rotation year is visible in one view — work periods, off periods, crew changes, all color-coded and crystal clear.
Want to know how many days you'll be offshore this year? It's right there.
WORKS WHERE YOU WORK
OffshoreMate runs offline. Once it's loaded, you don't need internet — which matters when you're on a rig with satellite WiFi that barely loads email.
It's lightweight, fast, and built mobile-first.
FITS YOUR ACTUAL SCHEDULE
We support all the common rotation patterns: 14/14, 14/21, 21/21, 28/28. Got a non-standard rotation? Set a fully custom pattern — any combination of on/off days.
Timezone-aware, so international crew changes are handled properly.
SHARE IT YOUR WAY
Export to iCal, Google Calendar, or Outlook with one click. Your rotation syncs to your phone and updates automatically.
Download a clean PDF to print, email to your family, or post on the fridge.
