Lloyd’s Register (LR) has delivered a fleet-wide energy transition roadmap for TMS Tankers, providing vessel-level analysis of compliance risks associated with CII, EU ETS and FuelEU Maritime regulations. The strategy identifies cost-effective decarbonisation pathways across TMS’s Aframax, Suezmax and VLCC fleets through emissions benchmarking, fuel readiness assessments and techno-economic modelling.
London | June 8, 2026 – Lloyd’s Register (LR) has completed a comprehensive fleet-wide energy transition strategy for Greek tanker owner TMS Tankers, providing the company with a detailed roadmap to navigate increasingly stringent emissions regulations while identifying the most cost-effective pathways toward compliance and long-term competitiveness.
The advisory project, which was first announced during Posidonia 2024, focused on TMS Tankers’ fleet of Aframax, Suezmax and Very Large Crude Carriers (VLCCs). The initiative was designed to assess the impact of evolving environmental regulations on vessel operations, fuel choices and future investment decisions as the maritime industry accelerates its decarbonisation efforts.
The study comes at a critical time for tanker owners facing mounting regulatory pressure from the International Maritime Organization’s Carbon Intensity Indicator (CII), the European Union Emissions Trading System (EU ETS), and FuelEU Maritime regulations, all of which are reshaping operational and commercial strategies across global shipping markets.

Vessel-Level Insight into Regulatory Exposure
According to Lloyd’s Register, the strategy provides TMS with detailed vessel-level visibility of current and future compliance risks by linking fuel consumption, trading patterns and operational performance directly to future regulatory costs.
LR Advisory established carbon intensity baselines across the fleet and assessed compliance risks under multiple emissions reduction scenarios. The analysis benchmarked TMS vessels against more than 300 comparable tankers, providing a detailed understanding of how individual vessels compare with industry peers and where future compliance challenges are likely to emerge.
The assessment examined operational factors including voyage distance, waiting times, fuel consumption profiles and trading routes to determine how each vessel’s performance could be affected as emissions regulations become progressively stricter.
By integrating operational data with regulatory forecasts, LR was able to quantify potential cost exposure associated with EU ETS carbon pricing, FuelEU penalties and future greenhouse gas reduction requirements.
Evaluating Decarbonisation Pathways
Beyond compliance analysis, LR conducted a detailed assessment of available decarbonisation measures that could improve vessel performance while minimizing operational disruption. The study evaluated a broad range of options, including speed optimization, energy-saving technologies, onboard carbon capture systems, biofuel adoption and alternative-fuel retrofits.
A structured gap assessment identified vessel-specific improvement opportunities and determined which emissions reduction measures would deliver the greatest benefits under different operational scenarios. The analysis also examined the practical challenges associated with implementing new technologies, including fuel availability, infrastructure readiness and commercial viability.
Future Fuel Readiness Assessment
A key component of the project involved assessing the suitability of alternative fuels for TMS’s tanker fleet. LR evaluated biofuels, liquefied natural gas (LNG), methanol and ammonia against the company’s existing trading routes and bunkering infrastructure to determine where realistic fuel transition opportunities exist and where supply constraints remain a challenge.
The assessment mapped alternative fuel availability across TMS’s key ports and bunkering locations, providing the company with a clearer understanding of which fuels could be adopted in the near term and which would require significant infrastructure development before becoming commercially viable.
The findings highlighted that while several low-carbon fuel options continue to gain momentum, fuel availability, regulatory uncertainty and infrastructure development remain critical considerations for shipowners planning long-term fleet investments.
Techno-Economic Modelling Identifies Optimal Compliance Strategies
The final phase of the project involved extensive techno-economic modelling designed to translate regulatory requirements into practical investment and operational decisions. LR analyzed each vessel individually to determine the most effective combination of operational improvements, fuel strategies and technology investments needed to achieve compliance while preserving commercial performance.
The modelling considered both existing European regulations and proposed greenhouse gas fuel intensity targets under the IMO’s emerging Net Zero Framework. This approach enabled the development of vessel-specific compliance pathways aimed at extending asset life, minimizing regulatory costs and maximizing revenue generation throughout each vessel’s remaining economic lifespan.
The roadmap also includes actionable recommendations such as targeted installation of energy-saving devices aligned with scheduled drydockings and gradual integration of biofuels where economically viable.
Strategic Response to Growing Regulatory Pressure
Jack Spyros Pringle, Global Head of Energy Transition Advisory at LR Advisory, said shipowners are increasingly confronted by overlapping regulatory requirements that require a more detailed understanding of financial and operational implications.
“Shipowners are now facing a convergence of regulatory pressure from CII, EU ETS and FuelEU, and the real challenge is understanding what that means commercially at vessel level,” Pringle said. “This work gives TMS a clear view of how each ship is exposed to future costs and which actions deliver the strongest return.”
He added that benchmarking against comparable vessels and analysing actual trading patterns allowed LR to move beyond broad industry recommendations and develop practical compliance pathways tailored to individual vessels.
Building Long-Term Resilience
Theo Kourmpelis, Global Business Director for Tankers at Lloyd’s Register, described the project as an important step in helping TMS prepare for a rapidly changing regulatory environment.
“TMS Tankers is taking a strategic, fleet-wide view of the energy transition, looking beyond near-term compliance to long-term resilience and competitiveness,” Kourmpelis said. “This roadmap gives TMS a practical basis to sequence investment, preserve commercial flexibility and make informed decisions across its tanker fleet.”
TMS Focuses on Data-Driven Decision Making
A spokesperson for TMS Tankers said the roadmap provides critical visibility into the relationship between current vessel operations and future regulatory costs.
“The strategy gives us a clear line of sight between how our vessels operate today and the cost of compliance under future regulation,” the spokesperson said. “That is critical for how we optimise deployment and prioritise investment across the fleet.”
The company noted that the analysis also clarifies which decarbonisation solutions are realistically available based on its operational profile and existing bunkering network.
“It also brings clarity to which decarbonisation options are realistically available to us based on our trading profile and bunkering infrastructure, allowing us to take a more structured approach to energy transition rather than reacting to regulation as it develops.”
Positioning for the Energy Transition
The completed strategy provides TMS with a comprehensive framework for managing the evolving challenges of maritime decarbonisation. By combining emissions benchmarking, regulatory cost modelling, fuel readiness assessments and vessel-specific techno-economic analysis, the project offers a data-driven foundation for future fleet planning and investment decisions.
As tanker owners face increasing pressure from regulators, charterers, financiers and cargo owners to reduce emissions, strategies such as the one developed by Lloyd’s Register are becoming an increasingly important tool for balancing compliance requirements with commercial performance.
For TMS Tankers, the roadmap represents a shift from reactive compliance planning toward a more proactive and strategic approach to navigating the maritime industry’s transition to a lower-carbon future.
Case Study: Creating a Tanker Fleet Energy Transition Strategy
Challenge
TMS Tankers required a clearer understanding of how its Aframax, Suezmax, and Very Large Crude Carrier (VLCC) fleets would perform as maritime emissions regulations continue to tighten. While the Carbon Intensity Indicator (CII) was already placing pressure on fleet performance, concerns were increasing around exposure to the European Union Emissions Trading System (EU ETS) and FuelEU Maritime regulations, particularly for vessels trading in and out of European waters.
At the same time, growing charterer decarbonisation expectations, an ageing fleet profile, and uncertainty around future fuel availability and compatibility were creating additional commercial and operational complexity. These factors highlighted the need for structured, long-term compliance planning and clearer fleet transition decision-making.
Approach Taken
LR Advisory developed a structured, data-driven assessment framework beginning with CII baselining across the fleet and scenario-based compliance forecasting under both moderate and aggressive emissions reduction pathways.
TMS vessels were benchmarked against approximately 300 comparable vessels using LR Advisory’s emissions and performance models. This analysis incorporated trading patterns, voyage distances, waiting times, and fuel consumption profiles to assess how operational behaviour directly influences compliance risk and future regulatory costs.
A detailed gap assessment was then conducted to identify vessel-specific improvement requirements and evaluate available decarbonisation levers, including speed optimisation, energy-saving devices (ESDs), onboard carbon capture technologies, biofuel adoption, and alternative fuel retrofit options.
A parallel risk assessment evaluated external factors influencing the transition strategy, including regulatory developments, commercial pressures, and fuel supply constraints. A future fuel readiness study assessed the applicability of biofuels, LNG, methanol, and ammonia against TMS’s trading routes and bunkering infrastructure.
Finally, LR Advisory applied vessel-level techno-economic modelling to determine optimal compliance pathways, balancing regulatory requirements with revenue performance and asset longevity. This included actionable recommendations such as ESD installations aligned with drydocking schedules and phased biofuel integration strategies.
Solution
Lloyd’s Register (LR) Advisory supported TMS Tankers in developing a comprehensive fleet-wide Energy Transition Strategy, combining regulatory benchmarking, gap analysis, decarbonisation pathway assessment, and fuel readiness evaluation.
The strategy was designed to provide a structured foundation for long-term decision-making under increasingly complex emissions regulation.
