An innovative marine engine efficiency solution

In April 2018, 170 countries, as part of the International Maritime Organisation (IMO), reached an agreement to cut carbon emissions from the global shipping industry to at least half by 2050. This is a considerable challenge, that requires collaboration between Governments, the marine industry, technology providers and beyond.

Bowman developed, prototyped and tested a new, marine-capable engine efficiency solution to meet this challenge head-on. This was thanks to a grant from Innovate UK, and a successful collaboration with Rolls-Royce Power Systems, Lloyds Register and University College London.

The Project

Using Bowman’s cutting-edge ETC 1000 system as the basis for development the companies worked together to achieve:

  • Market validation and reporting
  • Engine performance studies and modelling based on MTU Series 4000 M93
  • Prototyping of three marine turbo generators and four power electronics units
  • Testing in a specialist test facility and within a number of land-based applications
  • Mechanical and electrical marine compliance response documentation

As a result of their efforts, the group of companies created a clear roadmap and route to market, based on proven technology, and perfectly positioned to meet the IMO’s regulatory challenge.

Results

  • Demonstrated considerable fuel savings and a reduction in CO2 emissions for a number of ships currently in operation, at sea and in port
  • Achieved a positive benefit in specific fuel consumption savings up to 7.8% on MTU 4000 engines during the simulations
  • Predicted payback as early as 2.3 years
  • Achieved the project aims in demonstrating that the ETC system is suitable for marine certification
  • Discussions are underway with two large engine OEMs and a major ferry operator to bring this solution to market
