Capital Product Partners plans to install 14 of its ships with scrubbers, including its entire containership fleet and lone bulker.
The Greek shipowner said the work, which includes three crude tankers, would be completed "throughout 2019 and 2020."
Part of the plan is an agreement with Huyndai Merchant Marine which will bring a $4,900 per day rate rise on five 5,000 teu containerships once the equipment is fitted.
The project was announced as the Evangelos Marinakis-backed company reported a loss of $22.6m for the third quarter.
The figure included a $28.8m impairment charge following the $11.2m sale of the 160,000 dwt Amore Mio II (built 2001).
Excluding the impairment, the Partnership’s net income was $6.2m compared with $9.7m for the third quarter of 2017.
Capital's results were in line with Wall Street forecasts.
Distributable cash flow of $0.09 per unit was exactly as Wall Street has forecast, according to Wells Fargo.
