Propulsion & Emissions attracted a good audience including many ship owners

The 36th Motorship Propulsion & Emissions Conference, entitled ‘Ship energy efficiency today’, is now in progress at the Atlantic Kempinski Hotel in Hamburg, in the presence of some 160 people, including a good number of ship owners, operators and managers.

Following the welcome address and keynote speeches, conference chairman Lars Robert Pedersen of BIMCO introduced the first session, looking at the newbuild versus retrofit question as applied to eco-ships. One of the greatest barriers to introducing new energy saving technology is obtaining the finance, and two presentations, from the German HSH Nordbank and Clean Marine Energy of the US looked, respectively, at the market for eco-ships and innovative financial models to encourage take-up of energy saving measures. TecnoVeritas made a presentation on the economics of retrofitting, while Mr Pedersen himself examined the age-old charter question, looking at how BIMCO’s documents can accommodate energy saving in charter agreements and divide risks and benefits fairly.

The second session concentrated on future fuels, with a range of subjects including alternative fuels (DNV GL), low speed gas-fuelled engines (MAN Diesel), hybrid propulsion (Wärtsilä) and fuel emulsion (Green Energy). Following lunch, sponsored by ABB, the third session looked at the all-important lubrication issue, relating both to the current cold corrosion issue and the effect of low sulphur fuels in the near future. Total Lubmarine, Shell and ExxonMobil all gave their own view, all presenting 100BN cylinder oils for applications at risk from cold corrosion, and giving their views on oils for older engines operating at part load and likely outcomes of the 0.1% sulphur limit, the effects of which are still very uncertain, at least in marine applications. Parker Kittiwake rounded off the session with a presentation on onboard analysis methods, which the oil companies agreed was an important consideration.

Session four looked at energy efficient technology for ships, starting with Caterpillar’s twin fin propulsion system, and continuing with the ClassNK Napa software solutions. ABB looked at a system for optimising the diverse systems and sub-systems found on a ship to obtain the best overall efficiency, while Propulsion Dynamics of the US presented data from over 10 years of hull and propeller performance monitoring onboard some 400 ships.

Day One concluded with the conference dinner, sponsored by DNV GL, and held at the Parlament restaurant in Hamburg City Centre.
