Excel wasn't built for this
Merged cells, broken date math, one wrong drag away from chaos. Spreadsheets don't understand Mob, Demob or weather windows — you're fighting the grid, not planning the campaign.

your campaign schedule
in PowerPoint.
VesselGantt builds your offshore campaign schedule in the language you already use — Mob, Demob, Transit, Standby, Weather Window — and exports the board-ready slide in minutes.

The Friday-night problem
Great planners,
hostage to bad tools.
PowerPoint eats your week
Every schedule change means redrawing boxes by hand. By the time the deck looks presentable, the plan it shows is already obsolete.
Replanning is punishment
A vessel slips three days and you lose three hours. In offshore, change is the only constant — small changes shouldn't cost entire afternoons.
From blank to board-ready
Three steps.
No design skills.
01
Import or start
Drop your existing Excel — columns auto-map in seconds. Or pick an offshore template: IMR, drilling support, subsea construction.
02
Drag until it's right
Bars snap to days. Milestones, baselines and weather windows live on the canvas. KPIs — utilization, NPT — recalculate as you move things.
03
Export in one click
Editable PowerPoint, landscape PDF or Excel — themed, branded, with an executive KPI summary. Ready for the COO without touch-ups.
Built for the job
Not another
generic Gantt.
FEATURE_01
A Gantt that speaks offshore
Ten native activity types with real operational meaning — not colored rectangles you have to explain in every meeting.
- Mob, Demob, Transit, Standby, Port Call, Weather Window
- Milestone categories: decision gates, deliveries, regulatory
- Drag, resize and snap with day-level precision
- Multi-vessel swimlanes with gap compression
FEATURE_02
Exports you don't have to fix
One click produces the deck you would have spent Friday building. Executive mode hides technical noise and leads with the numbers leadership asks for.
- Editable .PPTX — every bar is a real shape
- Executive KPI slide: utilization, NPT, campaign days
- Themes + your logo and brand colors
- Landscape PDF and Excel workbook included
FEATURE_03
Your Excel, upgraded
Don't start over — bring the schedule you already have. The import wizard maps your columns, validates every row, and offers a Rev.0 baseline on the spot.
- 4-step wizard: upload → map → preview → confirm
- Auto-detects and maps your columns
- Updates existing tasks without killing your formatting
- Live KPIs and baseline comparison from day one
Simple, honest pricing
Cheaper than
one wasted Friday.
