Over the first four months of 2026, the Signal Ocean Platform recorded 787 crude voyages lifted from Russian ports, totalling approximately 593 million barrels. This insight goes a layer deeper than the dashboard view above: using the underlying voyage records, it examines who is commercially operating the tonnage. It isolates the share of voyages that carry Kazakhstan-origin CPC Blend rather than true Russian-origin crude.
Three findings stand out. First, Western (G7-coalition) commercial operators are involved in 38% of Russian-port liftings, but only 26% once CPC Blend is stripped. Second, the sanctioned share of total flow rises from 47% on the headline (including CPC) to 57% on a true-Russian-crude basis. Third, the Western fleet active in this trade is mainly old: 53% of the 162 Western vessels involved are over ten years old, rising to 58% of the 110 vessels that touched true-Russian cargo at any point in the period.
Commercial Operators — Western Share Falls Sharply Once CPC Is Removed
The Western market share, initially recorded at 38%, decreases to 25.7% upon the exclusion of CPC Blend voyages. This represents the most significant variance identified in the study: specifically, of the 299 Western voyages, 134—representingapproximately50%—constituteCPCBlendoperationsattheNovorossiysk-CPCterminal, involving the transport of Kazakhstan-origin crude as opposed to Russian-origin petroleum.
Conversely, the Unknown / Unattributed category remains largely unchanged across both analytical perspectives, adjusting from 290 to 287 voyages. Consequently, the activity within this group is almost entirely composed of true-Russian-origin exports. This segment exhibits the highest concentration of sanctions risk, as 90.3% of Unknown voyages involve vessels designated by the EU, OFAC, or OFSI.
Western (G7-coalition) - Higher exposure to True Russian Crude per Vessel Size
CPC Blend: 134 voyages (44.8% of Western total).
True Russian-origin: 165 voyages (55.2% of Western total).
Unlike Suezmax vessels, which primarily carry CPC Blend (Kazakh-origin), Aframax vessels are the workhorses for true Russian-origin crude.
72.5% of Aframax voyages (58 out of 80) carry true Russian crude.
In contrast, only 46% of Suezmax voyages (96 out of 208) carry true Russian crude, with the majority being the exempt CPC Blend.
Lower Overall Volume than Suezmax: While Aframax is the second most used vessel size, its total volume (80 voyages) is significantly lower than that of Suezmax (208 voyages), representing about 27% of the total Western-operated fleet in this dataset.
CPC Blend is loaded at the Novorossiysk-CPC marine terminal but originates from Kazakhstan, shipped via the Caspian Pipeline Consortium across southern Russia. Within the Russian-port system captured on the platform, the CPC complex (terminal plus SBM) is the single largest loading point of the period. The table below shows what happens when this Kazakhstan-origin flow is isolated:
Source: Voyage records — Western (G7-coalition) operators only. Yellow = CPC Blend; green = true-Russian-origin.
The distribution of voyages across vessel classes reveals a distinct operational preference based on the origin of the cargo. Suezmax vessels are split nearly evenly between CPC Blend and true-Russian crude, with 112 voyages (53.8%) dedicated to the Kazakhstan-origin CPC Blend and 96 voyages (46.2%) carrying true-Russian petroleum. In contrast, Aframaxes demonstrate a significant lean toward true-Russian exports, with 58 out of 80 total voyages (72.5%) transporting Russian-origin cargo, while only 22 voyages are attributed to CPC operations. Participation from the MR2 class is uniquely specialized, as all 11 recorded voyages were exclusively utilized for true-Russian trades.
This trend aligns with the logistical requirements of the underlying trades. The long-haul routes originating from the Novorossiysk-CPC terminal favor the economies of scale provided by larger Suezmax tonnage. Conversely, the shorter maritime corridors, such as Baltic-to-Europe and Baltic-to-Mediterranean routes, are more efficiently served by Aframaxes and, for the smallest parcel sizes, MR2s.
Monthly Trend - Western Activity Built Through the Period
Significant Growth in Activity: Total voyages by Western operators grew from 65 in January to 87 in April, representing a 33.8% increase over the four months.
Dominance of Suezmax Vessels: Suezmax vessels are the primary vessel class used by Western operators, accounting for the majority of voyages each month. Their activity peaked in March with 61 voyages.
Rising Aframax Usage: There has been a steady increase in the use of Aframax vessels, which rose from 16 voyages in both January and February to 27 voyages in April.
Voyage activity within the Western group demonstrated a clear upward trajectory over the four months. Following relatively stable levels in January and February, with 65 and 63 voyages respectively, activity accelerated markedly in March to 84 voyages before reaching a four-month peak of 87 voyages in April (+38%). From a fleet composition perspective, Suezmax vessels consistently dominated the trading pattern, maintaining a stable and significant contribution throughout the period with monthly voyages ranging from 45 to 61. Aframax participation displayed greater month-to-month volatility, fluctuating between 16 and 27 voyages. Meanwhile, MR2 vessels accounted for only a limited share of total activity; however, their participation remained steady across all four months.

Sanctions Exposure
The increase in the sanctioned share from 46.9% to 56.9% is primarily the result of removing predominantly non-sanctioned CPC Blend voyages from the dataset, which concentrates sanctioned activity within a smaller total pool of voyages. After excluding Kazakhstan-origin CPC Blend cargoes, the remaining 643 true Russian-origin voyages exhibit significantly higher sanctions exposure. Western-operated activity remained almost entirely compliant, with 99.4% of voyages classified as non-sanctioned. In contrast, the Unknown / Unattributed segment accounted for 44.6% of ex-CPC voyages and represented the main concentration of sanctioned activity, with 262 out of 287 voyages (90.2%) conducted by vessels sanctioned by the EU, OFAC, or OFSI. The findings highlight a clear distinction between the G7-compliant infrastructure supporting Kazakhstan-origin CPC Blend exports and the shipping networks transporting true Russian-origin crude.

Western Fleet Age - Structurally Old, Particularly on True-Russian Cargo
The 162 Western-operated vessels active in this trade are weighted to older tonnage. Suezmaxes dominate the count (114 of 162 vessels) and are the oldest sub-fleet — only 19 of 114 are under five years old, while 56 are over ten. Aframaxes (45 vessels) show a similar skew: 7 modern, 29 over ten.
Source: Voyage records — Western (G7-coalition) operators. Age calculated as (2026 − Year Built).
Looking at the 110 Western vessels that touched true-Russian-origin cargo specifically (the ex-CPC view): 64 of 110 are over ten years old (58%), and only 16 are under five years old (15%). The implication is that the Western fleet that remains active in true-Russian-crude movement after CPC is stripped out is meaningfully older than the headline Western fleet figure suggests, and is dominated by Suezmax tonnage approaching the end of conventional trading life.
Key Takeaway: Two Views Tell Different Stories
The headline platform view describes a 593-million-barrel Russian-port export trade, dominated by Aframax and Suezmax tonnage and split principally between Chinese, Indian, Mediterranean, and Continental destinations. That picture is correct as far as it goes, but it conflates two functionally different cargo flows: true-Russian-origin crude (subject to the G7 price cap) and CPC Blend (Kazakhstan-origin, outside the cap, but loaded at a Russian port).
Pulling those two flows apart materially changes the operator and compliance picture. The Western (G7-coalition) operator share drops by twelve percentage points (38.0% → 25.7%) when CPC is removed. The total sanctioned share rises by ten percentage points (46.9% → 56.9%) for the same reason. And the Western fleet that remains involved in true-Russian-origin movement, after CPC liftings are excluded, is older than the headline Western fleet figure indicates.
Discover the Data That Drives These Stories
This insight was produced by combining the Signal Ocean Platform Oil Flows dashboard (shown above). The platform supports interactive filtering by cargo group, origin area, destination, vessel DWT, and date grouping; the Voyage Details dashboard and Signal Ocean Data Warehouse APIs expose the underlying records that power the operator-level analysis presented here.
Methodology
• Source: Signal Ocean Platform voyage records, crude liftings ex Russian Federation load ports, 1 January – 30 April 2026.
• The underlying voyage feed contains the commercial-operator name only — no country, jurisdiction, parent-company, or beneficial-owner field.
• CPC classification: any voyage with origin port containing "CPC" tagged as CPC Blend. All other Russian-port liftings (Primorsk, Ust-Luga, Murmansk, Kozmino, Nakhodka, Sabetta, Prigorodnoye, non-CPC Novorossiysk) are classified as true-Russian-origin.
• Sanctioned = vessel appears on at least one of the EU, OFAC, or OFSI designation lists in the source dataset.
• Counts are voyage counts, not market-share by tonnage.

Increased Use of Renewable Energy:
Shipping companies are embracing renewable energy sources to power onboard systems and reduce emissions during port operations. Solar panels and wind turbines are being installed on vessels to generate clean energy, reducing reliance on auxiliary engines, and cutting down emissions. Shore power facilities in ports allow ships to connect to the electrical grid, eliminating the need for onboard generators while docked.
Collaboration and Industry Partnerships:
Recognizing that addressing emissions requires collective action, shipping companies, governments, and organizations have formed partnerships and collaborations. These initiatives focus on research and development, sharing best practices, and promoting knowledge transfer. Joint projects aim to develop and deploy innovative technologies, improve infrastructure, and create a supportive regulatory framework to accelerate the industry's transition towards a greener future. The Zero Emission Shipping - Mission Innovation.
To pave the way for a greener future in shipping, the availability of alternative fuels plays a vital role in their widespread adoption. However, this availability is influenced by factors such as port infrastructure, local regulations, and government policies. As the demand for cleaner fuels in shipping rises and environmental regulations become more stringent, efforts are underway to improve the accessibility of these fuels through infrastructure development, collaborations, and investments in production facilities.
Liquefied Natural Gas (LNG) infrastructure has seen significant growth in recent years, resulting in more LNG bunkering facilities and LNG-powered vessels. Nonetheless, the availability of LNG as a marine fuel can still vary depending on the region. To ensure consistent availability worldwide, there is a need for further development of LNG supply chains and infrastructure. For biofuels, their availability hinges on production capacity and the availability of feedstock. Although biofuels are being produced and utilized in various sectors, their availability as a marine fuel remains limited. Scaling up biofuel production and establishing robust supply chains are imperative to ensure wider availability within the shipping industry.Hydrogen, as a fuel for maritime applications, is still in the early stages of infrastructure development. While some hydrogen vessels have been tested or introduced in the first quarter of last year, the infrastructure required for hydrogen production and distribution needs further advancement.
Ammonia, as a marine fuel, currently faces limitations in availability. The production, storage, and handling infrastructure for ammonia need further development to support its widespread use in the shipping industry.Methanol, on the other hand, is already a commercially available fuel and has been used as a blend with conventional fuels in some ships. However, its availability as a standalone marine fuel can still be limited in certain regions. Bureau Veritas in October 2022 published a White Paper for the Alternative Fuels Outlook. This white paper provides a comprehensive overview of alternative fuels for the shipping industry, taking into account key factors such as technological maturity, availability, safety, emissions, and regulations.
