Efficient solutions for LNG carriers

When you need to optimise fuel efficiency for your LNG carriers and meet strict environmental regulations, Wärtsilä’s solutions will help you. You can choose a standard LNG system or a tailored one for your ship type.

Integrating your LNG system with other equipment will bring efficiency advantages. Wärtsilä’s LNG engines combined with a hybrid system will save you fuel. Less fuel used means a decrease in emissions – and therefore, compliance with IMO and EU regulations. More savings are possible with energy-saving technologies, digital solutions and smart services.

Wärtsilä’s solutions for LNG carriers are designed to work optimally together. They are compliant, reliable, cost-effective to operate, and ready for sustainable fuels.

How to solve the top 4 problems that every LNG carrier has

As an owner or operator of a gas carrier, your main goal is to keep the cargo moving safely and smoothly. At the same time, you face a set of common challenges no matter where you operate. No matter where you operate, the challenges include:

  • the need for efficiency in unstable markets
  • financial unpredictability
  • the need to avoid downtime as vessels become more complex 
  • dealing with the cost of emissions

Did you know? You could solve those problems, and this white paper tells you how.

How to reduce methane slip

When your ship uses LNG as fuel, you must be smart about methane slip. Methane is an extremely powerful greenhouse gas, and cutting methane emissions is the strongest lever the shipping industry has to slow climate change.

The good news is that the technology you need is already available – and proven in the field. Dramatic improvements are possible with the right insights and technology. Discover seven helpful and unbiased facts that can bring results – fast.

Spark gas conversion to cut methane slip emissions  

The Spark Gas Conversion is an upgrade for Wärtsilä 50DF engines. It replaces pilot fuel ignition with spark-ignited pure gas operation. This configuration is optimised for LNG, and it is proven to deliver

  • higher energy output per unit of fuel
  • 75% reduction of methane slip at 50-percent load

In addition to emission reductions, the conversion improves fuel efficiency—achieving up to 4.6% fuel savings at 50% load. These results are verified and can translate into substantial cost savings over time.

How to improve operational efficiency

Maximizing efficiency is crucial in the competitive world of LNG carrier operations. Here are three great ways to address your immediate operational concerns: fleet optimisation, services, and energy-saving technology. And once the investment is made, you will keep saving money in the coming years.

Fleet optimisation

Use vessel data to your advantage: choose Fleet Optimisation Solutions, FOS. Monitor the fuel consumption and emissions and a variety of energy efficiency indicators for a single vessel or a whole fleet of vessels – just as easily, and in real time. Automatic reporting will greatly reduce the workload for your personnel.
