News: Scrubber economics weaken as marine fuel premiums narrow
9th July 2020 11:17 GMT

Demand for scrubbers systems -- designed to clean the exhaust gases from a vessel’s main and auxiliary engines and boilers to remove sulfur dioxide gas -- has fallen, according to ship-owners and scrubber manufacturing companies.

Back in 2019, when the shipping industry was facing the imminent application of the so-called IMO 2020 sulfur regulations in bunker fuel, many shipowners opted to install scrubbers, seen at the time as among the most cost-saving solutions.

However, the global pandemic and a subsequent narrowing of the spread between high sulfur and low sulfur fuel oils has prompted a rethink, with shipowners now delaying the installation of scrubbers to minimize the financial impact.

“Despite the lower spread, the investment payback period for a scrubber is between half a year to one and a half years, depending on the cost of the scrubber and daily consumption, which allows for substantial fuel oil cost savings for scrubber-fitted ships,” Peter Sand said in a report by the Baltic and International Maritime Council.

When S&P Global Platts launched its VLSFO assessment in July 2019, the spread between the product and HSFO was $98/mt, before widening by 12% month on month to $110/mt in August. Since September, the spread has been narrowing again, dropping to just $49/mt as of May (see table).

Shipping services provider Clarkson stated that just under 30% of the VLCC fleet currently has a scrubber fitted, compared with around 14% of the Aframax fleet, with the larger ship sizes seeing the greatest number of scrubber installations. Overall, 14.2% of of all vessels, when measured in deadweight tonnage, has a scrubber installed.

It also stated the coronavirus crisis and resulting low crude prices, have led to “700 scrubbers which can be cancelled or postponed."

Several shipping companies have said they are postponing installations and Wartsila has announced a decline in new marine orders, largely due to a lack of scrubber investments.

In the current price environment I can't imagine many scrubber owners will be particularly pleased on their return on investment. But these things are surely temporary and that investment will make sense again one day. The post-IMO2020 expectation was that middle distillates values would explode as a result of increased demand but the Covid-19 pandemic has dampened all predictions. As a result, 0.5% and MGO are good value for money.

Nobody thought that hidden virus will produce a huge damage in the economies, since we had to care and to take firm rules to control the death worldwide. Indead, many lives we have lost in many countries, and the cost was a collapse in the activities in all countries due to restricted allowances in borders, and the cities. Marine Fuels demand falled down with the dropped in trips, and consequently the fuels prices too, following the surplus inventories anywhere in ports markets. This meant a narrowed value for the gap's prices between HSFO with LSFO, then the scrubbers units lost any advantage in the short time. Rodrigo Leiva - CHILE

2020 will be remembered as a historical landmark in the petroleum industry as a disruptive innovative technology will be launched on the market. Infinitive Petroleum has developed and patented the Dispersive Passive Hydrodynamic Cavitation technology whose breakthrough results from the combination of water micronisation and water and fuel homogenisation processes. The invented technology can add micronised water to any hydrocarbon fuel obtained from distilled petroleum, and the obtained water-in-fuel emulsions are capable of reducing carbon and greenhouse gases, toxic emissions (e.g. sulphur dioxide) and fuel consumption dramatically. The largest source of SO2 in the atmosphere is the burning of fossil fuels which is generated by power plants, locomotives, ships, other vehicles and heavy equipment. Infinitive Petroleum’s Dispersive Passive Hydrodynamic Cavitation technology can eliminate SO2 emissions! Over the past few years, the world industry has been put under severe pressure due to a delicate trade-off between development and sustainability. Time has finally come to take advantage of this remarkable scientific breakthrough and reconcile the protection of natural habitats and the Planet’s natural resources with human activities.
