Fleet Development & Technology

Innovative Technology

Evergas successfully continues to modernize its fleet with an average fleet age below 4 years. With its focus on modern efficient solutions, including clean LNG dual-fuel technology, Evergas is at the forefront of the industry with environmentally friendly vessels meeting all known current and future regulations.

Hull Design


Due to sharpened regulation, a period of high energy prices and heavy competition, a lot of development has been made in the field of hull optimization and design. Evergas puts high emphasis on minimizing energy and fuel consumption requirements, and has therefore gone through extensive design processes for all its hulls. Every hull is carefully designed and thoroughly tested in a reputed ship model basin. Apart from the hull itself, Evergas also performs rudder and propeller tests in this basin, to make sure that we achieve the most efficient overall ship design.

Dual Fuel Engines


Dual fuel capability allows us to comply with all existing emissions regulations when running the engines on gas. Still we have the flexibility to comply with these regulations by using MDO if gas isn’t available, and in areas where there are no emission regulations, the ships can use HFO. Depending on the availability and price of the various fuels, we are able to optimize our operations and offer the best solution to our clients.

Trilobe Cargo Tanks

Shaft Generators

trilobe 2

A recent improvement of the more classic bi-lobe design, the tri-lobe tanks offer higher containment capacity of around 30% for the same ship length. The vessel has the largest Type-C tank ever made and Evergas has pushed the limit from 36000 CBM to 85000 CBM with a newly constructed Trilobe tank.

Shaft Generator

Whether running alone or in combination with our dedicated diesel generators, the shaft generator allows for efficient, reliable and flexible power production for the high energy demands that exists on our gas carriers because of the re-liquefaction plants.

It takes 68 Mini Coopers to produce the same power as the Dragons is able to on its auxiliary system for cooling, operation and hotel.

Dragon VS - The Power at a Mini Cooper

If the Cargo tanks was removed from the Dragon we could carry around 5.750 mini coopers in the void space.

See below key features of our different classes.
  • Available with single or twin engines for high efficiency and full redundancy
  • First proven ethane fuel capability
  • Offering further exceptional flexibility in fuel choice, with capability to burn LNG, HFO & MDO
  • Designed to be compliant with Tier III
  • Shaft generators offering optimal power generation
  • Optimal cooling efficiency
  • Unique heat recovery system
  • Design also available with 32000 cbm cargo tank capacity. This is achieved by using dish head design of tanks, which makes carriage of NH3 possible but LNG not possible, due to nickel content.
  • Designed to fulfill requirements of EP class notation and Green Passport
  • Reduced NOx & SOx emissions
  • Low consumption and low CO2 emissions
  • Considerable fuel savings compared to similar standard desgins
  • Improved hull lines & high maneuverability
  • CP propeller, bow thruster & reduced length
  • Bi-lobe cargo tanks for increased cargo capacity
  • Increased operational efficiency and crew safety
  • Fully automated systems & one man bridge control
