Four ice-strengthened LNG carriers from Mitsui O.S.K. Lines’ (MOL) North series—North Mountain, North Way, North Sky, and North Air—remain anchored off Singapore, idle since EU sanctions removal in July 2025. Originally built for Russia’s Yamal LNG and Arctic LNG 2 projects, the vessels face charterer disputes and market challenges.
Sanctions Background
The EU sanctioned the Arc4-class ships in 2024-2025 for STS transfers near Murmansk and Yamal cargoes to Asia. After MOL assurances against Russian Arctic gas use, the EU delisted North Moon, North Ocean, and North Light in July 2025; the remaining four were never relisted but lack employment.
Current Status
North Mountain and North Way, renamed and reflagged under Russia in 2025, sit with minimal AIS data. North Sky and North Air, still MOL-flagged, joined the idle fleet. Daily lay-up costs exceed $50,000 per vessel amid soft LNG spot rates.
Industry Ramifications
Sanctions disrupted Novatek charters, forcing MOL to lobby via Japan. EU’s 20th package eyes further tanker service bans. The idling highlights risks for non-Russian owners in Arctic LNG trades.
