Scorpio Group has added a further 23 scrubber units for $33.3m from Pacific Green Technologies to be installed on its bulker and tanker fleets.

Taiwan’s state-owned shipbuilder CSBC Corp has completed an installation of a scrubber into a 13,000-teu containership owned by Hong Kong’s Orient Overseas Container Line (OOCL).

Cosco Shipping Heavy Industry (CSHI) and Wartsila have penned a memorandum of understanding to cooperate in the production and growth of the exhaust has cleaning market in China.

An estimated 4,000 ships will be fitted with scrubbers by 1 January 2020 when IMO’s global bunker fuel sulphur cap rule is enforced, according to the Exhaust Gas Cleaning Systems Association (EGCSA).

The hype around the use of open-loop scrubbers is risking the loss of focus on key issues of human health and the environment, the Exhaust Gas Cleaning Systems Association (EGCSA) has said.

Scorpio Group has provided details of $122m of scrubber installations for its tanker and bulker fleets.

VLCC owner DHT Holdings say its scrubber fitted vessels will be configured in such a way where it can burn 0.5% or less sulphur fuel where exhaust gas cleaning units are banned.

The popularity of scrubbers as a way to comply with the IMO’s 2020 sulphur cap has grown rapidly over the last six months with over 1,000 systems ordered in that period, according to classification society DNV GL.

The number of ships fitting scrubbers to meet the requirements of the 2020 sulphur cap continues to grow rapidly, but it is not an option available or suitable to all.

Despite Maersk Line's stance that sulphur should be removed from marine fuel at the refining stage, the Danish shipping giant is going to install scrubbers on a limited number of vessels.
