More than 300 participants from 64 IMO member-state delegations and 22 observer organizations participated in the session.
As part of discussions on the strategy for reduction of GHG emissions from ships, the Russian delegation presented a unique method to estimate atmospheric emissions from shipboard power generation. The approach was developed by the Central Marine Research and Design Institute (CNIIMF) at the request of SUEK and the Murmansk Commercial Seaport.
The CNIIMF scientists analysed the dynamics of vessels calling at Russia’s largest Arctic port, where for the last seven years a programme to replace small vessels by dry cargo vessels of the largest sizes, such as Panamax and Capesize, for coal exports has been consistently implemented.
In 2010, out of 488 vessels to call at the port, only 54 were of Panamax size and none of Capesize class. By 2016, while the total number of calls declined to 271, the port welcomed 101 Panamax vessels and 20 giant dry cargo Capesize ships. At the same time, the annual cargo turnover at the largest stevedoring company in the Arctic Basin remained stable at around 15 million tonnes.
According to the CNIIMF scientists, the combination of less total ship calls at the Murmansk Seaport and a higher proportion of calls from modern and larger dry cargo vessels led to a two-fold reduction in emissions from shipboard power generators over 7 years. As well, the use of bulk carriers less than 20 years old equipped with more advanced power generation systems combined with low-sulphur fuel and shorter times at berth on the back of faster and more intensive loading operations further supported a reduction in emissions.The Murmansk Commercial Seaport will continue implementing its policy of environmental footprint reduction. Measures are being developed to cut berthing time, as well as to reduce the utilisation of shipboard power generators during mooring by supplying electricity from shore.
