Esa Henttinen is Executive Vice President, NAPA for Operations, in the NAPA Group, a world leading software house supplying safe and eco-efficient solutions for ship design and operation.
Henttinen holds a Master's degree in Naval Architecture from the Helsinki University of Technology (Aalto University). He has worked with NAPA since 1999.
Henttinen has gained extensive experience in the marine industry by developing safe and sustainable solutions for ship owners, operators and seafarers.
The recent article in SustainableShipping 'IMO focuses on fuel consumption data collection' highlighted the continued political debate of how best to "measure, report and verify" emissions from international shipping.
Submissions on this subject to MEPC 66 were, to a large extent, responses to a US submission to MEPC 65 for a phased approach to tackling GHG emissions, starting with a data collection period to obtain information on typical ship energy consumption, with a view to longer-term efficiency standards.
The article said: "With regards to data collection, MEPC 66 agreed to establish a correspondence group to consider the development of a data collection system for ships, including identification of the core elements of such a system. The group will report to MEPC 67, scheduled for mid-October this year."
This is indeed welcome news to companies like NAPA, which have developed sophisticated technology that can accurately measure energy efficiency, and therefore greenhouse gases. We hope and anticipate that the correspondence group includes software houses and the technological knowledge they bring, in their considerations.
Accurate, real time monitoring for combined and customisable display data from ship systems already exists and is increasingly being utilised by shipowners and operators, who are able to instruct their crew to report ‘real time’ data ashore.
The benefits of real time date collection software for ships extend far beyond the important issue of transparency and information for measurement, reporting and verification. The latest software provides a solution in the shape of an accurate dynamic performance model that tunes the ship performance model on a continuous basis. This takes into account factors such as wave and wind resistance, propeller efficiency and effect or different drafts – to give up to 99.6% accuracy in voyage optimisation, trim optimisation and performance reporting.
Countering concerns that monitoring software is a costly option versus more traditional measurements of fuel consumption and emissions, such as noon reports and bunker delivery notes (BDN), we would say that such software not only monitors, but saves fuel. Moreover, some companies offer flexible payment options to spread the cost.
Comments made in plenary at MEPC 66 suggested that progress on the data collection phase could be held back by countries that are suspicious that it will form part of a drive to adopt further regulations on GHG emissions from international shipping, the article said.
Amid a boom in maritime software development, delays would only serve to work against the IMO's mission to oversee the transition of the industry to a more efficient and sustainable sector.
When it is governed by MEPC 65 + 66 with a concept to reduce greenhouse gas emissions , by starting with the collection of data to obtain information on typical ship energy consumption, then I say that is " carrying coals to Newcastle " because:
A shipowner ordered a ship with contractual guarantees , also to fuel consumption. And the known combustion equations yield the amounts of exhaust gas and exhaust gas contents - depending on the types of oil and oil -source localities .
So why should there still be measured for years ? To get time for a longer use of heavy oil ?
Your measurement technology can indeed discover additional "black sheep " among the suppliers of oil , but more ?.
And actually, the problem of global ship exhaust gases is described and our error therefore , which consists in the ignorance of modern cargo sailing ships .
The DynaRig of Prölss was presented in the 60-ies of the last millennium .
Lost time for a clean air and clean oceans.
