MV Theben

The RoRo vessel MV Theben is one of the two recently delivered ships with Wärtsilä EGC (Exhaust Gas Cleaning) systems, owned by a Japanese shipowner and currently being operated by Wallenius Wilhelmsen. The vessels are almost 200 metres long, 36.5 metres wide, and feature five liftable car decks, allowing for multiple configurations and a wide variety of customer cargo. The vessels can transport up to 8000 car equivalent units.

Wärtsilä’s scrubber system for MV Theben is one of the world’s largest multi-stream scrubber systems installed, and removes sulphur and particulates from the exhaust gases of the vessel’s main and auxiliary engines. The Singapore flag state authorities have recently approved Wärtsilä’s exhaust gas cleaning (EGC) systems onboard MV Theben and MV Themis, making it the first EGC to be approved by an Asian flag authority.

“Scrubbers are our preferred choice to meet the new emission regulations in ECAs and to meet the IMO-announced global cap for SOx in 2020/2025. After a thorough evaluation, we selected Wärtsilä to be our preferred scrubber supplier for the pilot retrofit installation on our Ro-Ro vessel, the MV Tarago in 2013, which was a success. This cooperation continued with four more Wärtsilä scrubbers on our recent newbuilding ships, built in Korea. Since our fleet now voluntarily operates on MGO in ports worldwide, we see scrubbers as an even more environmental friendly solution because they also reduce particle emissions when operating in ports around the world.”

The International Maritime Organization’s (IMO) Marpol Annex VI regulations are aimed at reducing air pollution levels from ships by reducing the sulphur oxide (SOx) content of the vessel’s engine emissions. The limits came into effect for ships operating inside Emission Control Areas with effect from January 2015. A global cap becomes effective from 1 January 2020, subject to a feasibility review to be completed no later than 2018.

Wärtsilä exhaust gas cleaning technology represents an economical and environmentally friendly solution that meets the highest standards of emission compliance. Wärtsilä’s SOx scrubber system solutions are suitable for both newbuildings and the retrofitting of existing vessels having either 2-stroke or 4-stroke engines, and are designed to provide flexibility and reliable operations.
