US-based marine technology firm Pacific Green Technologies is scaling back its exhaust scrubber business because of a narrowing spread between high- and very-low sulphur fuel oil and the effects of the Covid-19 pandemic.
The firm will close its office in Norway, which it said has not generated any revenue, and focus on on existing customers.
"As a result of Covid-19 and the narrowing of the oil price spread, we have been forced to rethink the sales strategy in our marine division," said chief executive Scott Poulter.
Pacific Green is the world's 11th biggest scrubber supplier, according to shipping classification society DNV GL, and has fitted 158 of the systems. They allow ships to continue to run on cheaper 3.5pc sulphur marine fuel oil beyond the International Maritime Organisation (IMO) global 0.5pc sulphur cap, which came into effect on 1 January.
The wider the spread between 3.5pc fuel oil and the IMO-compliant 0.5pc fuel oil, the shorter the payback time for shipowners after investing in a scrubber, which cost millions of dollars. The average weekly spread between 0.5pc fuel oil and 3.5pc fuel oil in Rotterdam was $305/t in the first week of 2020, but just $54.75/t last week. It has not been above $100/t since the beginning of March.
Prices for both grades began to fall in March, when the crude price dropped. The price of 3.5pc fuel oil held up better than 0.5pc fuel oil in Rotterdam, in part because of tighter supply and in part because of demand for 3.5pc fuel oil for use in US refinery cokers.
In the first week of this year 0.5pc fuel oil in Rotterdam averaged $598/t. It fell to $171/t by early May, and recovered to $299/t last week. For 3.5pc fuel oil, the weekly average was $293/t at the start of the year and $244.25/t last week, though it did near $100/t in early May.
The world's two biggest scrubber makers, Finland's Wartsila and Sweden's Alfa Laval, reported a drop in scrubber orders in the first quarter, blaming in part the narrowed spread. Oslo-listed shipowner Stolt-Nielsen had said it plans to cancel scrubber installations where possible.
Around 3,100 ships of a global fleet of 60,000 had scrubbers as of the start of 2020, according to DNV GL, and 1,100 installations were scheduled for this year. but only 150 fittings are scheduled for 2021-23.
