Three signals are shaping the next chartering wave: compressed build windows, firmer HSE requirements, and rising scrutiny on CO2 per mile. For offshore wind, oil & gas, and subsea, that trifecta translates into earlier commitments on critical tonnage and tighter logistics. When weather or permitting pushes a campaign to the right, activity clusters — and the vessels that de-risk schedules get booked first.

Operational impact: DP2 AHTS and walk-to-work vessels with motion-comp gangways become the gating resources on condensed workscopes; DP1 units struggle to meet minimums on certain SIMOPS. CTV planning shifts from single-base to hub-and-spoke to smooth crew changes and fuel. Survey/ROV spreads favor vessels with proven station-keeping and low fuel curves at 3–4 knots. Barges still move steel, but anchor handlers that can double as construction support win on utilization. Hybrid-ready CTVs and PSVs that manage hotel loads efficiently — and can run HVO/MGO blends where supply exists — are moving to the top of shortlists. Owners who evidence emissions intensity per delivered tonne‑mile clear vendor risk gates faster.

What to change in your charter plan: lock options on DP2 and W2W early; build port-dualization into your scope; and price transit CO2, not just day rate. Data transparency matters — AIS-backed utilization, bollard-pull curves, and real consumption at operating modes beat brochure specs. Matching closer to site often delivers double‑digit cuts in steaming hours, which can offset the premium for higher-spec tonnage while reducing schedule and HSE risk.

Takeaway: secure schedule-critical DP2/W2W capacity early, plan CTVs like a network, and let data — not habit — drive your charter list.
