Maritime Supply Chain Management: Shipping Routes, Ship Types, and Dimensions

  • Shipping Routes: Platforms like shipmap.org and MarineTraffic offer visual representations of major shipping routes. MarineTraffic, in particular, provides live maps, exploration tools, community features, and pricing options for monitoring fleets.

  • Core Shipping Routes: Key routes include the Yucatan Channel, Mona Passage, Windward Passage, Panama Canal, Magellan Passage, Oresund, Dover Strait, Gibraltar, Bosporus, Dardanelles, Suez Canal, Tsugaru Strait, Strait of Hormuz, Taiwan Strait, Luzon Strait, Bab el-Mandab, Cape of Good Hope, Strait of Malacca, Makassar Strait, Sunda Strait, Lombok Strait, and Torres Strait. These routes are critical for global trade and navigation.

  • Maritime Bottlenecks:

    • Panama Canal: This canal has size restrictions:

      • Old Panamax: Length 965 ft, Width 106 ft, Draft 39.5 ft, and Deadweight Tonnage (DWT) of 60-80.

      • New Panamax: Length 1200 ft, Width 161 ft, Draft 49.9 ft, and DWT of 60-100.

    • Suez Canal: Key specification is Width 164 ft, Draft 66 ft, accommodating Suezmax vessels.

    • Strait of Malacca: Key specification is Length 1312 ft, Width 193 ft, Draft 82 ft, allowing Very Large Crude Carriers (VLCC) with 130-200 DWT.
