Winter’s tight weather windows are quietly rewriting chartering math. When you only have a few hours between sea state spikes, the real constraint isn’t day rate—it’s certainty. That shifts selection toward vessels that can start work immediately, hold position precisely, and complete the task within a single window.

Operationally, this is why DP2 is showing up on more nearshore scopes. Cable pull-ins, jacket lifts from multicats, and mooring touch-ups now favor DP-capable tugs/multicats to avoid anchors on sensitive seabeds and shave setup time. With a six-hour window, the difference between a DP2 tug and a conventional tug can be the whole job: less gear to wet, faster approach, fewer aborts. For anchor-handlers, DP2 reduces anchor work cycles and accelerates short, surgical interventions between squalls.

On the chartering side, proximity is beating price. Vessels already within 100–150 nm of the coordinates get the call, because a long reposition risks burning the entire window. Owners who can flex crew and arrive warm get paid for readiness; charterers win by being specific. Include LAT/LON, draft limits, DP class, bollard pull, crane/winch specs, freeboard, and a target weather window. For CTVs, double-crewing and tighter 12/12 rotations are back to front-load uptime around short access periods—especially where quayside charging or quick turnarounds are available.

Takeaway: in winter, the closest DP-capable vessel beats the cheapest one every time.
