LNG-Ready Vessels Paradox: All Geared Up But Not Fueled!



The maritime industry is undergoing a significant transformation. As environmental concerns rise, there’s a palpable shift towards cleaner fuels.

Among these, Liquefied Natural Gas (LNG) emerges as a promising contender, offering a blend of environmental and operational benefits.

Quick Summary

  • LNG is gaining traction as a cleaner marine fuel.
  • “LNG-Ready” vessels are designed for potential LNG use but face challenges.
  • Economic, technical, and regulatory factors influence the adoption of LNG.
  • The number of LNG-fueled ships is growing, but they still represent a small fraction of the global fleet.

What Does “LNG-Ready” Mean?

When we say a vessel is “LNG-Ready”, we’re referring to ships designed to accommodate LNG fuel systems in the future. These vessels might not use LNG from the outset but have the necessary design provisions to make a switch feasible.

The primary distinction between LNG-fueled and LNG-ready vessels centers on their fueling systems and engine configurations.

LNG-fueled vessels are equipped with systems that actively utilize LNG as a primary fuel source. These ships often employ dual-fuel engines, which can run on both LNG and traditional marine fuels, providing flexibility in fuel choice based on availability and cost.

On the other hand, LNG-ready vessels are designed with the necessary provisions to accommodate LNG fuel systems in the future.

While they might not be currently using LNG, their design ensures that they can be retrofitted to incorporate LNG fueling systems and, if needed, transition to dual-fuel engines to leverage the benefits of LNG.

The Rationale Behind LNG-Ready Vessels

LNG offers several advantages:

  • Environmental Benefits: LNG burns cleaner than traditional marine fuels, leading to significant reductions in emissions.
  • Economic Considerations: As regulations tighten, LNG presents a way for shipowners to future-proof their investments.
  • Operational Flexibility: Given the evolving marine fuel landscape, being LNG-ready offers shipowners the flexibility to adapt based on future fuel availability and economics.

Cost Considerations for LNG-Ready Vessels

The decision to adopt LNG as a marine fuel is heavily influenced by its economic viability. While environmental benefits are a significant driver, the bottom line remains a primary concern for many shipowners and operators. Here’s a more detailed look at the cost considerations:

Price Dynamics: Traditional Fuels vs. LNG

  • Traditional Marine Fuels: Historically, IFO380 and MGO have been the dominant marine fuels. Their prices have been influenced by global oil markets, geopolitical events, and refining capacities.
  • LNG Pricing: Unlike traditional marine fuels, LNG prices are often linked to natural gas benchmarks. This can lead to different price trajectories compared to oil-based fuels. Additionally, the emergence of spot markets for LNG has introduced more variability in pricing.

Energy-Equivalent Pricing: Understanding LNG-380e and LNG-MGOe

  • LNG-380e: This is the price for an amount of LNG that delivers the energy equivalent of one metric tonne of IFO380 bunker fuel. It provides a direct comparison between the cost of LNG and traditional heavy bunker fuel, allowing shipowners to make informed economic decisions.
  • LNG-MGOe: Similarly, LNG-MGOe offers a price comparison between LNG and Marine Gas Oil (MGO). Given that MGO is generally more expensive than IFO380 but offers cleaner burning properties, this comparison is crucial for operators considering a shift towards cleaner fuels without fully transitioning to LNG.

Conversion and Retrofitting Costs

Transitioning to LNG, even for LNG-ready vessels, involves costs:

  • Infrastructure: Installing cryogenic tanks and associated systems can be expensive. The vessel might also need modifications to accommodate the added weight and changed weight distribution.
  • Engine Modifications: While some LNG-ready vessels might have dual-fuel engines, others might require significant modifications or even replacements to use LNG.

Training and Operational Costs

LNG, due to its unique properties, requires specialized handling:

  • Crew Training: Crew members need training to handle LNG safely, understand its properties, and operate new fuel systems. This training represents an ongoing cost, especially as crew members rotate.
  • Operational Adjustments: LNG’s cryogenic nature means that it evaporates if not used. This “boil-off” gas can be used as fuel, but managing it requires operational adjustments that might have associated costs.

Potential Savings and ROI

Despite the upfront costs, LNG can offer savings:

  • Fuel Cost Savings: Depending on the price dynamics, especially the LNG-380e and LNG-MGOe benchmarks, LNG can offer cost savings over the operational life of the vessel.
  • Regulatory Compliance: As emission regulations tighten, non-compliance can lead to fines and operational restrictions. Using LNG can mitigate these risks, leading to indirect savings.
  • Operational Efficiency: Modern LNG-fueled engines can offer better fuel efficiency compared to older oil-fueled engines, leading to savings in the long run.

Challenges Faced by LNG-Ready Vessels

Despite their potential, LNG-ready vessels face several challenges:

  • Infrastructure: The global LNG bunkering infrastructure is still in its nascent stages.
  • Training: Crews need specialized training to handle LNG.
  • Market Dynamics: The maritime fuel market is evolving, with new alternatives emerging, adding to the uncertainty.

The Technical Aspects of LNG-Ready Design

LNG-ready vessels have specific design considerations:

  • Storage: They’re equipped with space provisions for cryogenic tanks.
  • Propulsion: Engine designs can accommodate LNG or are dual-fuel capable.
  • Safety: Enhanced ventilation, leak detection, and containment systems are crucial given LNG’s unique properties.
