Stena Bulk to install exhaust gas scrubbers on 16 tankers; $55M investment

Stena Bulk, one of the world’s leading tanker shipping companies, has href="https://www.stenabulk.com/press-and-news/press-releases/stena-bulk-install-exhaust-gas-scrubbers-16-tankers">made a major investment in scrubbers; 16 units will be installed before January 2020. Ten IMOIIMAXes, 5 Suezmaxes and one of standard MR will be equipped with the after-treatment system. The total investment is worth US$55 million, including equipment, installation and time out of service.

Payback time of investment is between 1.5 and 2.5 years which has already been secured by hedging the fuel spread.

By installing scrubbers on board, Stena Bulk will comply with the upcoming IMO Sulfur cap regulation, which limits the sulfur content in fuel oil used on board vessels globally to a maximum of 0.50% from today´s 3.50% limit. The regulation comes in effect in 1 January 2020. As a result of the new regulation, the global shipping fleet will be required to either install scrubbers on board or to use a compliant fuel with the maximum sulphur content of 0.50% (outside Emission Control Areas (ECAs)).

We evaluated the different options and came to the conclusion that for our business by installing scrubbers we will secure greater availability of fuel for our vessels and by so limit our exposure to not finding the right fuel around the world and by that stay flexible in our trading. Even doing so we know it will require some changes and probably massive challenges in the planning logistically. We will however prepare ourselves best possible so that we can secure at least the same level of support to our customers as today.Stena Bulk President & CEO Erik Hånell

The scrubber to be installed is an Open Loop Hybrid Ready with Water Cleaning, which not only removes the sulfur but also particles from the exhaust.

An open loop cleaning system takes seawater, uses it for scrubbing, treats it and discharges it back to the sea. A closed loop system uses freshwater treated with an alkaline chemical such as caustic soda for neutralization and scrubbing. The wash water is re-circulated and any losses are made up with additional freshwater.

Hybrid systems can operate in either open or closed loop mode and depending on design may operate with either freshwater or seawater when in closed loop mode.
