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.
Routed sea distances from Surabaya (Tanjung Perak) to the principal global hubs, computed by ArcNautical's routing engine — around land and through the canals a ship actually uses, not great-circle.
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 5,454 distinct vessel detentions (sourced from OpenSanctions, as of 2026-08-02). Vessel-level detention probability is computed by ArcNautical using flag performance, vessel age, deficiency history, and ownership opacity.
