Weight of Freight: TMX spurs new Aframax, VLCC trade in Pacific basin
The first three months of Canada's Trans Mountain Expansion (TMX) have sent a surge of crude to refiners in California and China, shifting tanker demand in the Pacific basin.
The 590,000 b/d TMX project nearly tripled the capacity of Trans Mountain’s pipeline system to 890,000 b/d when it opened on 1 May, linking Alberta's oil sands to Canada's west coast for direct access to lucrative Pacific Rim markets, where buyers are eager for heavy sour crude.
Between 20 May, when the first TMX cargo began loading, and 20 August, about 165,000 b/d of Vancouver crude exports landed at ports on the US west coast, primarily in California, up from about 30,000 b/d in that same span last year, according to data from analytics firm Kpler.
The freight rate for a Vancouver-US west coast Aframax shipment averaged $1.98/bl for Cold Lake between 1 May and 20 August. This ranged from a low of $1.50/bl from 1-3 May when shipowners repositioned to the region in anticipation of TMX to a high of $2.32/bl from 13-14 June, according to Argus data.
The new oil flow into the US west coast has displaced shipments from farther afield in Ecuador and Saudi Arabia. Crude exports from those countries into the US west coast averaged 110,000 b/d and 25,000 b/d, respectively, between 20 May and 20 August, down from 155,000 b/d and 135,000 b/d over the same stretch in 2023, according to Kpler.
The growth of the Vancouver market, which benefits from its proximity to California, has reduced tonne-miles, a proxy for tanker demand, into the US west coast. This has outpaced slightly lower crude demand, which fell in part due to Phillips 66 halting crude runs at its 115,000 b/d refinery in Rodeo, California, in February to produce renewable fuels, as well as weaker-than-expected road fuel demand this summer.
Tonne-miles for US west coast crude imports fell by 14pc to 106bn between 20 May and 20 August 2024 compared with the same period a year earlier, Vortexa data show, while overall crude imports declined just 8.6pc to 1.37mn b/d, according to Kpler.
PAL-ing around with VLCCs
Though much of Vancouver’s exports have been shipped to the US west coast, Canadian producers have found ready buyers in Asia-Pacific as well, where about 160,000 b/d of Vancouver exports went between 20 May and 20 August, compared with none a year prior, Kpler data show.Buyers and sellers have displayed a preference for using ship-to-ship transfers onto very large crude carriers (VLCCs) at the Pacific Area Lightering zone (PAL) off the coast of southern California, rather than sending Aframaxes directly to refineries in east Asia. Of the 30 Vancouver-origin Aframax cargoes that have landed in China, South Korea and India, 19 were transferred onto VLCCs at PAL, Kpler data show. Seven cargoes were sent directly to east Asia on time-chartered Aframaxes — the majority by Suncor — and just four were sent using spot tonnage, likely due to the expensive economics of trans-Pacific Aframax shipments.
The Vancouver-China Aframax rate between 1 May and 20 August averaged $5.90/bl, with a low of $4.94/bl from 19-20 August and a high of $6.41/bl from 1-10 May and again from 4-12 June, according to Argus data.
Over the same time, the cost to reverse lighter, or transfer, three 550,000 bl shipments of Cold Lake crude from Vancouver onto a VLCC at PAL averaged about $8.055mn lumpsum, or $4.92/bl, with a low of $4.35/bl from 8-13 August and a high of $5.45/bl on 22 May, according to Argus data. This includes $150,000 ship-to-ship transfer costs at PAL, 15 days of VLCC demurrage and three days of Aframax demurrage for each reverse lightering.
VLCC costs could change preferences
Though it may have been cheaper to load TMX crude on VLCCs at PAL since May, volatility in the VLCC market — which often falls to yearly lows in summer before climbing to seasonal highs in the winter — could entice traders to opt for direct Aframax shipments if VLCCs hit their expected peak in the winter.
VLCC costs for shipments from the US west coast to China are influenced by the VLCC markets in the Mideast Gulf and Brazil, where ships look for their next voyage after discharging on the US west coast.
For now, Vancouver-loading Aframax rates are under pressure from the reemergence of VLCCs in what had become an Aframax trade in Thailand, boosting Aframax supply in the Pacific and pulling the class’s rate to ship crude from Vancouver to the US west coast to its lowest level in more than three months on 19 August.
In mid-July, VLCCs resumed discharging via single point mooring (SPM) at Thailand's port of Map Ta Phut for the first time since January 2022, ship-tracking data from Vortexa show. Prior to the SPM's return to service, VLCCs could discharge cargoes only by lightering onto smaller Aframaxes, which would then unload at a different berth in the port.
This created demand for about eight Aframax lighterings each month, but with VLCCs in Thailand again able to discharge directly, that demand is effectively halted, putting downward pressure in the broader southeast Asia Aframax market.
Since July, two Aframaxes have left the southeast Asia market for Vancouver, according to ship tracking data from Kpler: the Eagle Brisbane, which previously was used in lightering operations at Map Ta Phut, and the Blue Sea, which recently hauled fuel oil from nearby Singapore to China.

Iraq advises foreign firms to curb output
Iraq advises foreign firms to curb output
Washington, 20 March (Argus) — Iraq on Friday advised international oil companies to curb output at the fields they operate, declaring force majeure because of the disruption to exports from the country's south. Iraq has effectively lost access to the 3.4mn b/d of export capacity through Basrah as a result of the near-halt of transit through the strait of Hormuz. The oil ministry cited crude oil storage reaching its maximum capacity, which it said required a scaleback of production in the oil fields operated by international companies. "We will make every effort to resume exports as soon as possible; however, the situation is unpredictable," the oil ministry told the foreign firms. Invoking force majeure, retroactively to 3 March, allows Baghdad to pause revenue and production sharing contractual arrangements with foreign companies. Baghdad said it has cut its own crude production to 1.5mn-1.6mn b/d to prioritize domestic refining and electricity generation. Argus estimates production at around 1.2mn b/d. Iraq resumed crude exports from its northern Kirkuk fields to Turkey's Ceyhan port on 18 March at an initial rate of 250,000 b/d, according to the oil ministry. International oil companies operating in Iraq's Kurdistan region have already halted production, following repeated missile and drone attacks on energy infrastructure carried out by Iran-aligned Iraqi militia groups after the US and Israel attacked Iran on 28 February.

UK clears US to use bases for Hormuz defensive strikes
UK clears US to use bases for Hormuz defensive strikes
London, 20 March (Argus) — The UK has approved the use of British bases for the US to carry out "defensive operations to degrade the missile sites and capabilities" being used by Iran to attack ships in the strait of Hormuz, the government said today following a meeting of cabinet ministers. The UK had previously limited US use of its bases to counter threats directly risking UK lives or interests. Downing Street condemned Iran's widening of targets to international vessels and said the UK is co-ordinating a viable plan with partners to safeguard navigation through the strait. But it reiterated that the UK will not be drawn into the wider conflict. Around 20mn b/d of Middle East crude and refined products — roughly 25pc of global seaborne oil trade — was transported through the Hormuz strait last year. But since the US-Israeli war with Iran began on 28 February, tanker traffic has slumped in the wake of repeated Iranian missile and drone attacks on ships and energy sites in the region. Options to bypass the strait are limited, leading to a sharp spike in oil and gas prices. US president Donald Trump has castigated the UK and other Nato allies for not helping the US to reopen the waterway.

Australia mulls rise in oil, gas profits tax
Australia mulls rise in oil, gas profits tax
Sydney, 20 March (Argus) — Australia's upstream oil and gas lobby has warned Canberra against raising taxes on the sector, arguing it could lead to worsening supply and higher energy prices if it harms investment. Modelling has likely been commissioned to increase taxation on the gas industry ahead of the May federal budget, as global energy prices soar, a source with knowledge of the matter told Argus . The Petroleum Resource Rent Tax (PRRT) is designed to tax profits produced from offshore fields, which fall under federal jurisdiction. The state onshore producers pay state government royalties as well as federal business taxes. But this would only succeed in stopping investment in new supply, lead to gas shortfalls, higher prices and threaten Australian industries, Australian Energy Producers chief executive Samantha McCulloch said on 20 March. "While international gas prices have surged, Australian gas prices remain relatively low, and the market is well-supplied. We should not take this for granted," McCulloch said. Mild weather has resulted in Australia's gas demand remaining muted in recent weeks, with ample supply available and restocking of gas storages underway. But high international spot LNG prices due to the US-Iran war may eventually impact domestic markets, as replacement cargoes are sought by Asian buyers. The Argus -assessed AWX for month-ahead spot gas deliveries to Wallumbilla and the AVX for month-ahead spot gas to Victoria were both A$11.05/GJ today, both also rising A$0.015/GJ from a week ago — the third consecutive week the AWX has remained flat to the AVX. This compares to the Argus Gladstone fob price — an LNG netback indicator calculated by subtracting freight and costs associated with production from the delivered price of LNG to Asia-Pacific — which was A$31.74/GJ ($23.56/mn Btu) on 19 March, up from A$19.72/GJ a year earlier. Taxation calls The tax review comes three days after the influential Australian Council of Trade Unions, a key funder of the ruling Labor party, called for the PRRT to be replaced with a 25pc levy on revenue from LNG exports. Tax reform is on the government's agenda, federal energy minister Chris Bowen said today, praising treasurer Jim Chalmers for his changes to the PRRT brought in two years ago. But Bowen refused to offer more details, saying he does not comment on cabinet processes. Under those 2024 budget measures, changes to the PRRT cut the percentage of taxes able to be avoided through deductions for spending on project development to 90pc each year.

Kuwait's Mina al-Ahmadi plant attacked by drones
Kuwait's Mina al-Ahmadi plant attacked by drones
Dubai, 20 March (Argus) — Kuwait's 346,000 b/d Mina al-Ahmadi refinery came under new Iranian drone attacks in the early hours of 20 March, state-owned Kuwait Petroleum Corporation (KPC) said. The attacks caused a fire at several units of the refinery, but no injuries were reported, a KPC statement said. Emergency response teams are in the area and have been trying to contain the fire. "As a precautionary measure, a number of refinery units were shut down," KPC said. The new attack comes soon after Kuwaiti and Saudi Arabian energy complexes were damaged from drone hits on 19 March. Iran earlier warned that retaliatory attacks in response to the Israeli bombing of its gas processing facilities will continue. US president Donald Trump said Israel agreed to his request to stop targeting of Iran's energy facilities. Israel's prime minister Benjamin Netanyahu later confirmed his agreement to hold off attacks on Iranian gas fields.
