Denmark Ramps Up Environmental Inspections on Shadow Fleet Vessels

Denmark has announced a new round of tightened environmental inspections targeting aging ships in its waters. Particularly those associated with Russia’s so-called “shadow fleet.” The Danish Maritime Authority, together with the Environmental Protection Agency, will focus efforts around Skagen Red, a congested anchorage at the northern tip of Denmark, which it calls the gateway to the Baltic.

Environment Minister Magnus Heunicke said that many older vessels navigating Danish sea lanes pose elevated risks to the marine environment, and the government is now enforcing basic environmental regulations more aggressively. The inspections will include checks on waste disposal, ballast water compliance, scrubber water discharge, fuel standards, and scrapping certificates.

Shadow Fleet Under Scrutiny in Busy Anchorage Zone

According to the report, Denmark sees thousands of vessels passing through its waters annually, with a large number anchoring in Skagen Red. Many of these ships are old and under-insured, increasing environmental hazard if non-compliant with regulations. The country is now granting port-state control teams broader authority to board vessels in anchorage and demand documentation.

In parallel, Denmark will implement “sniffer” emissions monitoring across the Great Belt Bridge, measuring sulfur content in ship exhausts to enforce SOx and NOx limits within the Emission Control Area (ECA). The measure is expected to begin before year-end.

Political Messaging and Regional Momentum

Denmark frames the initiative in part as pushback against Russian maritime strategy. Industry Minister Morten Bødskov declared that Denmark must use “all tools” to protect its waters, particularly from dilapidated vessels operating under dubious legal structures, implicitly referencing Putin’s shadow fleet. Meanwhile, Russia has condemned the actions as tantamount to piracy and responded with naval escorts of its tankers in the Baltic.

The inspection increase builds on a broader EU trend toward stricter regulation of the shadow fleet. Last week, France detained a suspicious vessel suspected of false-flagging, holding it nearly a week before release. A signal that enforcement in Europe is intensifying.
