A process for drilling a well into the seafloor at an offshore drilling location, in particular in arctic regions, the process comprising: drilling a top hole part of the well during a winter season where the water at the drilling location is at least partly covered by ice; and initiating drilling a lower part of the well extending into a hydrocarbon-bearing formation during a subsequent off-winter season where the water is less ice infested than during the winter season.
