The Project:

During the 2016 and 2017 ice-free seasons, Foss completed a major sealift to an oilfield development project on remote Sakhalin Island off the coast of eastern Russia – including delivery of the largest land-based drill rig in the world. Traveling more than 240,000 nautical miles, the project included multiple tows from Texas and South Korea. Fifteen barges, 15 ocean-going tugs, and six shallow-draft tugs safely and successfully delivered 39 modules weighing as much as 2,600 tons.
