Ulsan: seafarer FAQ

Is shore leave allowed at Ulsan?
Shore leave at Ulsan is governed by South Korea immigration rules, the flag administration's policy, and the port authority's local rules. Seafarers normally need their seaman's book + a shore-leave permit issued by the agent. Confirm with your agent before going ashore — local policy changes frequently.
What visa or shore-pass do I need for Ulsan?
Seafarers calling at Ulsan on a vessel are generally exempt from regular tourist visas under Convention 108 / 185 (Seafarers' Identity Documents) if their flag administration has ratified the convention and they hold an SID. The standard document is the seaman's book + ship's crew list. South Korea may also require a shore pass issued by the agent. Confirm before you board the vessel — visa rules vary by nationality and by recent immigration-policy changes.
Is there a seafarer welfare centre at Ulsan?
Yes — 1 seafarer welfare centre is listed for Ulsan in our directory. The centres are typically run by the Mission to Seafarers, Stella Maris (Apostleship of the Sea), or a regional ministry, and offer wifi, transport, shop, chaplaincy, and advocacy. Walk-in is normal; no appointment needed.
Is there a crisis or welfare helpline I can call from Ulsan?
Yes — 6 helplines are listed for South Korea in our directory, plus ISWAN's 24-hour multilingual SeafarerHelp (+44 20 7323 2737) and the ITF Helpline. Helplines handle crisis support, abandonment, wage theft, mental health, and bereavement.
What's the nearest hospital to Ulsan?
Most major ports have a port-area hospital with seafarer-accustomed admissions; the welfare centre and the ship's agent can both advise. For serious cases, the nearest international hospital is normally in the same city or the next major city. The nearest major airport is Ulsan Airport (USN), about 7 km away — useful for medevac planning.
