Analysis by BIMCO has found that scrubbers were installed on 399 ships in 2022, and although this represents a fall of 24% year on year, currently 13% of bulker, container, and tanker ships have a scrubber installed.
Despite the slowing rate of installations, BIMCO analysts believe taht the share of ships with a scrubber is set to increase in coming years as 17% of ships in the shipyards’ order books are expected to have a scrubber installed.
Since 1 January 2020, ships have had to use ultra or low sulphur fuel (eg ULSFO or VLSFO) to comply with limits for sulphur emissions. However, ships can continue to use the less expensive heavy fuel oil (HFO) if they install a scrubber. But the price premium for VLSFO has turned out to be less than initially estimated. On 31 December 2019, the day before the new IMO regulation was implemented, the price premium for VLSFO in six of the world’s largest bunkering ports averaged US$ 347/t. Since then, the premium has averaged US$ 149/t. It has been as low as US$ 50/t for an extended period during 2020 and as high as US$ 400/t during June/July 2022.
The higher the VLSFO premium, the more attractive the investment in a scrubber is because the payback period is shorter. The lower-than-expected VLSFO premium has likely discouraged owners from installing scrubbers, particularly on smaller ships with lower bunker consumption and lower savings as a result. In fact, the average dry bulk, container, and tanker ship with a scrubber has a capacity of 140,845 dwt whereas those without have an average of 51,743 dwt. Therefore, the 13% of the dry bulk, container, and tanker ships with scrubbers represents 29% of the deadweight capacity. The crude tanker fleet has the highest installation rate with 32% of the ships and 38% of the deadweight capacity having scrubbers installed.
The percentage of ships with scrubbers is set to increase in the coming years as 17% of the dry bulk, container, and tanker ships in the shipyards’ order books are expected to have scrubbers installed. However, those 17% only amount to 24% of the deadweight capacity in the order book and the scrubber deadweight percentage could therefore decrease.
BIMCO says that in the long term, the use of scrubbers to cut sulphur emissions may reduce as decarbonisation efforts will increase the use of alternative fuels that are sulphur compliant.
