Alternative fuels and technologies

DNV GL offers a range of services related to alternative fuels and technologies in shipping which includes the Alternative Fuels Insight platform, class services, advisory services and the Maritime Academy.

Class services

Based on our experience, DNV GL has developed several class rules and notations to support the switch to alternative fuels, preparing ship owners for lower sulphur limits and more. Our rules cover liquefied, compressed gases and low-flashpoint liquid fuels. Based on our class rules and notations, we provide class services for low-flashpoint fuels covered by the IMO’s IGF Code as well as for fuels which are not yet covered by IMO rules.

Rules and notations:

  • Mandatory Class Notation "Gas fulled" for gas fuelled ships (also for gases not yet covered by the IMO IGF-Code)
  • Voluntary Class Notation "Gas ready" for ships prepared for gas as fuel.
  • Mandatory Class Notation "LFL fuelled" for ships using low flashpoint liquid fuels (e.g. methanol)
  • Mandatory Class Notation "FC(Power)" or "FC(Safety)" for fuel cell systems
  • Mandatory Class Notation(s) "Battery(Safety)", "Battery(Power)": DNV GL rules for lithium-ion battery installations on board ships
  • Voluntary Class Notation for Exhaust Gas Cleaning Systems. DNV GL recently introduced a new class notation for exhaust gas cleaning systems (EGCS)

For further information regarding applicable rules for the alternative fuels and technologies please compare DNV GL paper "Assessment of Selected Alternative Fuels and Technology" and the AFI platform or contact our experts.

Advisory services

DNV GL Maritime Advisory is separate from class activities and supports customers with a variety of services to make the right technological and financial decisions.

Advisory can support customers in a variety of services. As marine and industrial engineers, economists and environmental specialists, DNV GL has the deep knowledge across multiple disciplines needed to offer reliable solutions. We advise the maritime sector on environmental regulations and compliance options, we measure and benchmark your environmental performance, and support you in making the best business decisions on environmental technology.

Our services in environmental technology and alternative fuels include:

  • Fuel decision support
  • Emission analyses and assessments
  • Alternative Fuels Insights portal (AFI)
  • Feasibility studies
  • Technology qualification
  • Triple-E: environmental and energy efficiency rating scheme for ships
  • Control system software testing

AFI – Alternative Fuels Insight platform

The digital map to a low emission future: comprehensive insights into worldwide bunkering availability and market data on alternative fuels for ships. Following the success of LNGi and the increasing interest in alternative fuels in shipping, DNV GL has developed a new platform that provides reliable and comprehensive market and bunkering insight for alternative fuels. The AFI platform makes the information currently in LNGi, and equivalent information on other alternative fuels, available to the public for free. AFI is a web-based platform which provides a reliable overview of the uptake of alternative fuels, with worldwide and continuously updated information. The platform gives detailed and visual insight into existing and planned bunkering opportunities, complemented by thorough statistics and fleet status for alternative fuels.

Initial features on Alternative Fuels Insight:

  • Interactive map of bunkering infrastructure for LNG, LPG and methanol, with detailed project data
  • Statistics on ship uptake for LNG, LPG, scrubber, batteries and methanol
  • Encyclopaedia with information on alternative fuels needed for well-informed decision-making
  • Interactive fuel finder, for fuel request and contact between ship owners and fuel suppliers

Maritime academy

The maritime academy offers training courses designed to help our clients overcome the challenges related to conventional and alternative ship fuels. We offer courses on, among others:

  • Air pollution from ships in practice: The course’s objective is to gain advanced knowledge about exhaust emission legislation, abatement technology and alternative fuels.
  • Low-sulphur fuel – basics and experience: Participants will gain detailed knowledge for managing the international requirements regarding sulphur reduction for ship newbuildings and ships in service.
  • Gas as ship fuel: The course gives participants an overview of the current developments in the field of gas as ship fuel.
  • SOX Exhaust Gas Cleaning (EGCS) – in practice: Become familiar with different SOX EGC technologies available on the market, and understand applicable requirements regarding SOX EGC according to MARPOL Annex VI and MEPC.259(68).
