Intelligence

The Bosporus fleet and the Gibraltar fleet operate in the same Paris MoU region. They are subject to the same inspection regime. They are not the same fleet.

Over the past four weeks, DataGalley observed inbound vessel traffic across the principal approach corridors into European waters. The fleet profiles at each corridor tell a clear story, and one that any vessel risk assessment should account for.

The Bosporus

The inbound fleet is older and smaller. Comoros and Togo-flagged vessels average build years in the late 1970s. Palau-flagged tonnage averages 1995. Turkish-flagged vessels dominate in volume but average 4,200 GT and a 2003 build year. The classification societies certifying this fleet include Turkish Lloyd, Dromon Bureau of Shipping, and the Indian Shipping Register. These names appear at the Bosporus and at no other European approach corridor.

The Strait of Gibraltar

Gibraltar is a different world. Liberia-flagged vessels average 70,261 GT and a 2011 build year. Danish and German tonnage entering through the strait averages above 200,000 GT. These are mega container ships on intercontinental rotations, classed by DNV, Bureau Veritas, and Lloyd's Register. The deep-sea fleet concentrates here.

The Skagerrak

Between these two extremes, the northern approaches carry their own character. The Skagerrak is a Nordic corridor. Norway contributes 33 vessels, more than any other flag at any gate, with Sweden adding another 15. These flags barely register at Gibraltar or the Bosporus. The fleet is smaller, heavily weighted toward general cargo and chemical tankers, and classed almost entirely by DNV. It operates as a regional trade corridor with its own distinct fleet.

The English Channel

The English Channel carries the most diverse traffic. 42 Dutch-flagged vessels, 39 Portuguese, 37 Maltese, 29 Liberian. Build years spanning from the 1970s to 2026. Tonnage from 497 GT coastal cargo to 229,376 GT ultra-large container ships. Everything passes through the Channel, which makes it the corridor where averaging is most misleading. A vessel profile that fits the Channel average describes almost no individual vessel actually passing through it.

What this means

The corridor matters. A vessel entering through one gate carries a structurally different risk profile than a vessel entering through another. Any assessment that does not account for this is averaging across populations that have very little in common.
