🇸🇪 Sweden
Baltic Sea · Multi-Purpose Port
In the last 180 days, ArcNautical recorded 70 vessel arrivals at Stockholm, with Passenger accounting for 32% of port calls — higher than the Baltic Sea regional average of 13%. Stockholm in Sweden operates in a semi-enclosed shallow basin with seasonal ice and the strictest environmental regime in commercial shipping. December–April ice coverage requires vessels to meet Finnish-Swedish Ice Class for independent navigation or rely on icebreaker escort, and ice-edge position varies enough between years that conventional deterministic routing models fail. Since 2022, Russia's invasion of Ukraine has transformed the security architecture: NATO maritime presence has increased substantially, and sanctions against Russian energy exports have disrupted traditional traffic patterns. The Baltic is also a designated Particularly Sensitive Sea Area (PSSA) and Sulphur Emission Control Area (SECA), requiring low-sulphur fuel or exhaust gas cleaning systems.
Across 70 distinct vessel arrivals, 68 carry a confirmed AIS ship-type code. The most common categories at Stockholm:
Stockholm falls under the Paris MoU. The Paris Memorandum of Understanding does not publish a bulk per-vessel detention CSV. ArcNautical evaluates per-vessel detention probability using flag-state performance (3-year rolling rate from the 2024 Paris MoU annual report), vessel age, deficiency history, and ownership transparency. Paris MoU PSC inspections remain among the most rigorous globally.
