Raises Shadow Fleet Safety Concerns Also for Norway’s Coast

The fallout from the Arctic Metagaz explosion is being felt far beyond the Mediterranean, with knock-on effects now constraining Russia’s Arctic liquefied natural gas (LNG) export logistics and exposing vulnerabilities in the system Moscow has relied on to bypass Western sanctions.

Since early March, shipments from the Arctic LNG 2 project have slowed noticeably. Before the incident, Russia maintained a relatively steady export pattern despite restrictions, using a network of ice-class carriers and intermediary storage to move cargoes out of the Arctic.

Under that system, LNG produced at the Utrenniy terminal was loaded onto specialized carriers and transported to the Saam floating storage unit (FSU) near Murmansk. There, ship-to-ship transfers enabled further delivery by a separate fleet of vessels, many of them operating with limited transparency over ownership and insurance.

Industry data indicates that prior to March 3, the project managed roughly two cargo liftings every 10 days, reflecting a stable – if constrained – operational rhythm.

Exports slow down

That pattern has since been disrupted.

Shipping activity linked to Arctic LNG 2 has slowed in recent weeks, with fewer pickups and delayed onward transfers. Market participants attribute the slowdown in part to changes in routing decisions following the Mediterranean explosion.

Russian-linked LNG carriers appear to be avoiding the Mediterranean, instead taking longer routes around the Cape of Good Hope. The detours add significant transit time, reducing the frequency with which vessels can return to load new cargoes.

The delays are creating a bottleneck further upstream.

Two ice-class LNG carriers, Christophe de Margerie and Alexey Kosygin, have been idling in the eastern Barents Sea in recent days, according to ship-tracking data. Both vessels are reported to be loaded with LNG from Arctic LNG 2 but have been unable to discharge, as storage capacity at the Saam FSU remains constrained.

The floating storage unit is understood to be near capacity, holding earlier cargoes that are awaiting pickup by outbound vessels. However, those vessels are still en route, with extended transit times limiting their availability.

Shipping data suggests that two shadow fleet LNG carriers, Arctic Vostok and Zarya, are not expected to arrive at Saam FSU until around April 8. Additional vessels, including Arctic Mulan and La Perouse, are projected to arrive much later in April.

The resulting congestion is forcing Novatek, the project’s majority owner, to slow loading activity at Arctic LNG 2 and idle vessels that would otherwise be cycling between production and storage points.

Novatek has not publicly commented on the operational impact, but the slowdown underscores the challenges facing Russia’s LNG sector under sanctions, particularly for projects reliant on complex logistics and limited shipping capacity.

Libya takes action

Beyond commercial effects, the Arctic Metagaz incident has also drawn attention to safety risks associated with vessels operating in the shadow fleet.

Following the explosion, the damaged tanker drifted for more than three weeks in the central Mediterranean, carrying an estimated 800 tonnes of oil products as well as an unspecified quantity of LNG. Authorities in Malta and Italy monitored the vessel, conducting aerial surveillance, and establishing safety zones of several nautical miles.

Officials from both countries raised concerns about the potential environmental impact and risks to maritime traffic, and called for coordinated action at the European level.

However, no joint intervention was immediately undertaken. The vessel continued to drift across different maritime zones, moving from Libyan waters toward Malta and Italy.

A response came only this week when Libyan authorities moved to take the vessel under tow, aiming to prevent it from approaching offshore oil infrastructure and coastal areas. The tanker’s final destination and status remain unclear.

Shadow fleet vessels

The episode has highlighted uncertainties over how coastal states should respond to distressed vessels linked to sanctioned entities, particularly when ownership structures are opaque and standard insurance arrangements may not apply.

Maritime analysts say such cases can complicate decision-making, as authorities weigh environmental risks against legal and financial considerations tied to intervention.

The issue may be of particular relevance to countries along northern shipping routes, including Norway, where sanctioned Russian vessels transporting oil and LNG regularly transit close to the coastline. Norway has said it does not intend to board Russian shadow fleet vessels like France and Sweden have recently begun to do. 

At the same time, recent developments suggest that Russia’s Arctic infrastructure is drawing increased attention in the broader conflict with Ukraine. Reports this week indicated that an attack on the port of Vyborg damaged a new Arctic patrol icebreaker, Purga, under construction.

While the full implications remain unclear, both the Arctic Metagaz and Purga incidents point to a widening geographic scope of risks affecting Russia’s energy and maritime assets.

Together, these developments illustrate how disruptions outside the Arctic can have cascading effects for the region, while also raising broader questions about maritime safety, regulatory coordination, and the resilience of sanctioned export systems.
