Containerships overtake crude oil tankers as most scrubber-fitted sector

Containerships overtake crude oil tankers as most scrubber-fitted sector

Overview

Containerships with a collective cargo carrying capacity of 5.3m TEU are now fitted with an exhaust gas cleaning system (scrubber) to remove sulphur oxides (SOx) from the exhaust gasses generated by the combustion processes in marine engines and thereby comply with the IMO 2020 global sulphur regulation which came into force on 1 January 2020.

By the start of July, the share of the containership fleet with scrubbers installed exceeded that of the crude oil tanker fleet. At that time, the container shipping sector became the most scrubber-fitted amongst the main cargo carrying ship types.

“In order to cut the sulphur oxides emission, shipowners who can afford to buy a scrubber have done so to a substantial extent, with investments predominantly directed towards high consumption ship types,” says Peter Sand, BIMCO’s Chief Shipping Analyst and continues:

“Choosing the scrubber option to comply with the sulphur regulation was heavily debated as 1 January 2020 approached. But even with the low bunker fuel price spread between high and very-low sulphur fuels in the current market, it is safe to say that the investments are economically sound.

“However, the payback period on the investment is obviously extended at a price spread of USD 67 per MT, compared to an expectedly normalised price spread in the range of USD 100-USD 200 per MT,” Sand says.

While the scrubber-fitted fleet of main cargo carrying ship types now counts 2,600 ships, most of the fleet - 20,000 ships - are without a scrubber.

Size increasingly important

The bigger the ship, the more fuel it consumes. This explains why the uptake of SOx scrubbers is more popular for VLCCs, Capesizes and Ultra large containerships, than for their much smaller peers such as Aframax, Handymax/Handysize and feeders.

For VLCCs and Capesize sectors, scrubber-fitted ships as a share of the fleet (measured in DWT), currently amount to 30%. By year-end, the share is likely to have grown to 35%. For Post-Panamax (15,000+ TEU) the share has already exceeded 40% and is likely to reach 50% by the end of 2020.

Pending retrofits of 429 ships

56.3% of the current container shipping orderbook (1.2m TEU) will have a scrubber onboard when they are delivered, but more importantly, the pending retrofits of 1.5m TEU pushes up the total scrubber count.

Adding ongoing and pending scrubber retrofits to those that will be on board newbuilds brings the total scrubber capacity count to 8m TEU for containerships (31.6%),  141m DWT for crude oil tankers (30.9%) and 226m DWT of dry bulker capacity (23.5%) once all is installed.

Most time consuming to retrofit a containership

At any time since the start of 2019, yards have mostly been retrofitting dry bulkers and containerships, whereas crude oil tankers have seen the lion’s share of scrubber installations occur on board newbuildings.

In 2020 alone, the number of days spent on a containership retrofit has averaged 68 days ranging between 56 days in February and 79 days in July. This compares to an average number of days spent on a bulk carrier in 2020 of 46 days and 41 days on a crude oil tanker (source: Clarksons).

Bunker price spread peaked at USD 353 per MT on New Years’ Eve

The bunker price spread is currently just USD 67 per MT if the fuel is purchased in Singapore, the world’s largest bunkering port. Local market conditions mean that the comparable spread in other significant bunkering hubs, like Rotterdam and Fujairah, is USD 46 and USD 74 per MT respectively as per 11 August 2020.

The narrowing of the price gap between low- and high-sulphur fuels means that the spot market earnings differential (i.e. bunker cost savings) for a capesize bulker on 3 January compared to 7 August this year have declined from USD 7,626 per day to USD 1,095 per day.

Uncertainty evaporated fast

Choosing to comply to the new sulphur regulation without a scrubber installed requires a ship to run on a low-sulphur fuel oil. Since 1 January 2020, the global refinery industry has supplied the shipping sector with mainly low-sulphur fuel oil, with the more expensive distillate, marine gas oil, a distant second.

For the first six months of 2020, the share of total Singapore fuel sales amounted to 18% for heavy-sulphur fuel oil, 71% for low-sulphur fuel oil and 11% for marine gasoil.

“The debate on scrubber economics is all but gone now, as 2020 is in full swing and focus has turned towards COVID-19, and how that impacts the business. What remains are the economic realities and technical obstacles the industry is dealing with daily,” Sand says, adding:

“Cost savings are essential to all, but despite a considerable share of the fleets now being scrubber-fitted, the largest part of the fleet continues to operate without,” Sand.
