Singapore MPA steps in to curb bunker fuel quality issues

The Maritime and Port Authority of Singapore has taken steps to ensure the fuel contamination issue, which has so far impacted dozens of ships that bunkered at the city-state, does not escalate further as it continues its probe.

MPA has contacted the relevant bunker suppliers to take necessary steps to stop supplying the particular batch of fuel, and also informed all ships that were supplied with the fuel to exercise caution, the regulator told S&P Global Commodity Insights April 7.

MPA had launched an investigation to determine the cause of the latest off-specification bunker fuel issue after several cases of chlorinated hydrocarbons were detected in marine fuel deliveries, mostly for high sulfur fuel oil, in the world's largest bunkering port.

"Further investigations are currently ongoing. MPA will not hesitate to take action should there be any non-compliance," it said.

The recent bunker fuel quality issue in Singapore is a reminder of the Houston fuel quality problem that arose in 2018, when many ships consumed contaminated fuel and suffered engine damage before it was discovered that the fuel was unsafe to use.

Valuations surge

The global fuel oil market has been in a turmoil with limited product availability, largely attributable to less-than-usual Russian oil flowing into the marine fuel oil pool. Amid this, the Asian HSFO market has been caught in the eye of a storm as tight availability is further compounded by fuel quality issues in Singapore.

This has meant that few suppliers were now in a position to offer product to the spot market. As such, offers have not only drawn down to a trickle, but even those with product were only able to commit delivery about 10 days out.

The premium for Singapore-delivered 380 CST bunker over the Mean of Platts Singapore 380 CST HSFO assessment has progressively ticked higher in the recent days to hit a near two-year high of $35.97/mt on April 7. The differential was last higher at $39.78/mt on April 23, 2020, S&P Global data showed.

Quality concerns

Global fuel testing and inspection companies Veritas Petroleum Services and Maritec were among those to highlight their recent findings related to HSFO bunker fuel quality issues in Singapore.

VPS said in a statement March 31 that through the course of February-March, it had identified 34 ships that received from two Singapore suppliers HSFO deliveries contaminated with up to 2,000 ppm of chlorinated hydrocarbons. The fuel even met the ISO8217 specifications upon each delivery, VPS said.

"These bunker fuel contaminations have affected 14 vessels so far and the impact has been failure of the fuel system to the auxiliary engine resulting in loss of power and propulsion creating a blackout," VPS said.

Fuel system failure arose from seizure of the fuel pumps and plunger and barrel corrosion, caused by the bunker fuel contaminants, it said, adding that these problems appear to be continuing to affect an increasing number of ships.

Maritec said March 17 it had tested several samples representing HSFO deliveries in Singapore from March 4-13 and detected chlorinated organic compounds by GCMS test methods.

Source of theses organic chlorides could be from chemical used in engine air coolers and cleaning agents used in the dry-cleaning industry, and should not be present in bunker fuels at this level, it added.

Interactive: Seaborne trade in Russian oil under G7 price cap

Russia, one of the world’s largest oil suppliers, has increasingly turned to non-Western firms to transport its crude to overseas buyers during its ongoing war with Ukraine . With a dual goal of undermining Russia’s war chest without creating significant disruptions to global supplies amid inflation pressure, G7 countries and their allies have banned tanker operators, insurers and other services firms from facilitating seaborne Russian crude exports unless the barrels are sold for no more than $60/b. The price cap regime, which came into force Dec. 5, 2022, does not directly cover tankers flagged, owned and operated by companies outside the G7, the EU, Australia, Switzerland and Norway, and not insured by Western protection and indemnity clubs. While such ships tend to be older and less maintained, their share in Russia’s crude exports market has been rising in recent months amid strengthening prices of Urals -- the OPEC+ member’s flagship crude grade -- and tightening sanctions enforcement by the West. Non-price-capped tankers have a larger market share in shipping Russia’s Pacific crude exports, according to analysis of S&P Global Commodities at Sea and Maritime Intelligence Risk Suite data. Crudes such as Sokol, Sakhalin Blend, and Eastern Siberia–Pacific Ocean grades are more often involved in these trades than Russian barrels from Baltic or Black Sea ports like Urals. Tanker operators in Greece, Europe’s top shipowning nation, managed to keep their traditionally strong market position in Russia in the first few months since the price cap took effect before giving ways to their peers in the UAE, Russia, China and Hong Kong.

Red Sea turmoil has so far spared oil supplies, but buyers have reasons to worry

A series of attacks on shipping routes in the Red Sea has so far spared oil supplies from witnessing major disruptions, but oil importing countries are spending sleepless nights amid concerns that any escalation could potentially alter the situation drastically. Although the attacks disrupted container shipping lines, oil shipments remain largely stable. However, concerns stem from the fact that supply chains will likely have to adjust very quickly should the disruption persist. As existing oil tanker contracts are often hard to change, some ongoing traffic will continue to move through Red Sea passages. Any new insurance issued for Red Sea routes could add about $1/b or more to voyage costs, according to S&P Global Commodity Insights. Re-routing will increase voyage length, in-transit times and fuel costs. In addition, it will result in higher vessel utilizations, which could lift global freight rates as well as widen inter-regional crude spreads. Surely, more ships are avoiding the Red Sea and Bab al-Mandab strait after a spate of attacks by Yemen's Houthi militants, threatening the strategic chokepoint for global seaborne trade. Many shippers, tanker owners and some oil companies have suspended voyages through the area. Russia's oil exports are particularly exposed to further Red Sea disruptions as Moscow ships some 80% of its crude to Asian markets. The attacks are expected to keep insurance costs high and prompt many tankers to take the longer route via the Cape of Good Hope, increasing ton miles and voyage durations, as well as tightening supplies and driving up freight rates. Even for the route via the Suez Canal, higher fees effective this year combined with a carbon tax for Europe-bound cargoes, will increase overall costs for charterers. Special report: Taking the long way around: Ships divert from the Panama Canal Although the rerouting of tankers away from the Red Sea, a major conduit for oil loaded in Russia, will surely raise shipping costs, the impact will be transitory. Roughly 7 million-8 million b/d of crude oil and products transited the Red Sea in recent months, according to S&P Global data. The market, for sure, will adjust to the changing flows, but the re-routing will lead to more oil on the water for a longer period of time. Russian crude shipments, should they avoid the Red Sea, are most affected due to a much longer haul to Asia around Africa. And amid tighter fleet capacity, lingering geopolitical conflicts are expected to boost tanker freight in 2024 despite ongoing OPEC+ supply cuts and a possible slowdown in oil demand growth. Implications for Asia As the biggest oil importing region, Asia may not witness dramatic changes to near-term oil supplies amid the ongoing Red Sea crisis, but refiners are chalking out alternative plans to ensure steady feedstock flows in the event of an escalation, a move that could inflate insurance costs and crimp refining margins. Although the region relies on imported oil for the bulk of its needs, the strategic push among Asia's top importers to massively diversify their import baskets over the years, as well as expand strategic storage, will come in handy to ensure smooth and uninterrupted flow of feedstocks. The Red Sea crisis has three aspects to it, as far as Asian oil flows are concerned. First, any escalation will create hurdles for Russian crude flowing to Asia, forcing buyers to look for substitutes from other origins. Secondly, for products moving from Asia to Europe, exporters are cautiously watching developments before taking the plunge. And lastly, longer routes have the potential to create incremental bunker fuel demand in Asia. Oil flows into China have not been impacted much by the Red Sea turbulence, as fewer cargoes are headed there on that route. In addition, the impact on Russian oil flows to India has been minimal, with no major diversions seen so far. Russia contributed over 35% of India's total crude imports in 2023, amounting to 1.7 million b/d, according to S&P Global data. Asian oil buyers are not necessarily concerned about Middle Eastern sour crude supplies for 2024, as major sellers, including Saudi Aramco and Abu Dhabi National Oil Co., fully respect Asian customers' demand regardless of their production cut commitments. However, the economics for cracking Middle Eastern sour crude have been deteriorating as the costs of bringing Persian Gulf barrels to the Far East have been rising with shippers demanding risk premiums, while tanker insurance costs are also trending higher. Asian refiners may even look at cutting Middle Eastern term contractual volumes and explore other options like African, US and South American crudes to maximize margins. US crudes, for one, is becoming increasingly more attractive for Asian refiners as the price of lighter and sweeter WTI crude is nearly on par with high-sulfur Persian Gulf grades on a delivered basis. Supply cushion The attacks in the Red Sea continued even after the US-led alliance took military action to establish deterrence. The risk of a wider escalation also increased with Pakistan's retaliatory strikes against Iran for alleged Iranian militant attacks in Pakistan. Overall, the geopolitical tensions in the Middle East have only increased over the weeks. However, oil markets have largely shrugged aside the risk due to a lack of physical disruption to oil shipments and weak macro fundamentals. But increased risk in the Middle East is probably putting a floor to oil prices amid weak demand. S&P Global expects fundamentals to improve in the second half of 2024 and prices to move up. Still, OPEC+ market management and the alignment between Saudi Arabia and Russia on OPEC+ policy will be critical for oil markets in 2024. S&P Global forecasts Platts Dated Brent to average $83/b in 2024 and $76/b in 2025. A sharper economic slowdown or disagreement within OPEC+ on production restrain remains the biggest risk for oil markets going into 2024.
