🇮🇩 Indonesia
Southeast Asia · Multi-Purpose Port
Voyages from Surabaya (Tanjung Perak) in Indonesia navigate the world's busiest shipping lanes, anchored by the Strait of Malacca — a 550-mile corridor through which roughly 100,000 vessels transit annually. The Malacca and Singapore Straits remain a persistent piracy hotspot, with ReCAAP recording dozens of incidents per year; most are low-level opportunistic theft at anchor, but the geographic concentration demands attention in any voyage risk model. Waters off eastern Sabah and the Sulu Sea present a more severe kidnap-for-ransom threat. PSC inspection regimes vary substantially across ASEAN members, and the Tokyo MOU detention data identifies which flags and vessel types face elevated scrutiny in the region.
Limited port-call data — fewer than 10 distinct vessels observed at Surabaya (Tanjung Perak) in the last 180 days. ArcNautical does not publish a vessel-type breakdown for low-traffic ports to avoid statistically misleading percentages.
Surabaya (Tanjung Perak) falls under the Tokyo MoU. The Tokyo Memorandum of Understanding (Asia-Pacific) maintains the most active publicly-available regional PSC programme. Across the last 24 months, the Tokyo MoU detention dataset records 5,331 distinct vessel detentions (sourced from OpenSanctions, as of 2026-06-14). Vessel-level detention probability is computed by ArcNautical using flag performance, vessel age, deficiency history, and ownership opacity.
