Offshore schedules are compressing—and it’s changing vessel demand overnight. OEM resets, grid tie-in delays and tighter weather windows are bunching work into shorter bursts, forcing projects to stack campaigns and chase the same tonnage at the same time.

Operationally, three shifts stand out. First, DP2-capable AHTS and larger MPSVs tighten quickly during tow-outs, mooring spreads and cable lay; where a non-DP tug worked last year, clients now ask for station-keeping to keep spreads 24/7 inside short windows. Expect regional rate spikes and earlier options.

Second, CTV scheduling is becoming a routing problem, not a simple day-rate. Multi-farm hopping, sea-state caps and speed–fuel curves mean a 28–30-knot boat with reliable HVO supply and smart berth slots can deliver more transfers than a faster hull burning time in port. Contracts are shifting toward hybrid day-rate plus availability KPIs.

Third, carbon is entering the charter conversation as a line item. Owners who can evidence emissions, fuel flexibility (HVO/methanol-ready/hybrid) and credible mobilization plans are winning tenders. Cutting a few hundred nautical miles of transit by matching vessels closer to site can save tens of tonnes of CO₂ on an AHTS campaign—data that now moves decisions.

Takeaway: lock the critical DP2 pieces early, treat CTVs like a network optimization, and price carbon alongside day rate.
