countries, it has the capacity to respond to a major oil spill of up to 30,000tonnes in the Gulf of Finland, 20,000tonnes in the Archipelago Sea and 5000tonnes in the Gulf of Bothnia, in open water conditions and within three days of the incident occurring. In icy conditions, the target is to achieve the same result within 10 days of an incident. In order to meet these ambitious
targets, Finland, Estonia and Russia still need six more response vessels such as Louhi, each with a storage capacity of in excess of 1000m3
. Louhi is designed to remain on station In peacetime, Louhi is operated by the Finnish navy on behalf of SYKE.
the Baltic Sea and Baltic Sea Policy, which was published in 2009, and an earlier report on the development of oil spill response preparedness in the period 2009-18. Overall the improvement of response preparedness required by the documents
is estimated to require a total investment of €200 million (US$290 million) by the state and €100 million (US$145 million) by the rescue authorities. By 2015 the Finnish Government wants to ensure that, working in collaboration with neighbouring
without replenishments for 20 days if required and has a range of in excess of 11,000km. Te vessel is fitted with a suit of oil spill equipment from Lamor in Finland. Lamor’s sales director for Finland and the
Baltic, Juha Muhonen, said: “Louhi has been fitted with our newest technology. None of the other 14 Finnish oil spill response ships have the same kind of equipment, although they are also equipped with our technology. “Louhi’s oil recovery technology is
based on Lamor’s brush-type skimming equipment. The vessel has four different types of brush skimmers, including built-in brush conveyor belt skimmers, bucket skimmers mounted on cranes, free-floating offshore skimmers with umbilical hose reels and so-called ice brushes mounted on the aſt deck of the vessel,” Mr Muhonen explained. “Te ship has also been equipped with
new ice brushes developed by Lamor to operate in Arctic conditions. Another new innovation is a passive stabilisation system tank, which enables oil to be recovered even in a 2m swell.” Fitting all of the equipment in a 71m-long
vessel was a challenge. “The general arrangement and equipment layout of the vessel was crucial,” Mr Muhonen said. “Te ship designer accomplished this task very well whilst working together with the various government agencies involved and with Lamor. Te general arrangement of the vessel includes a 300m2
working deck at
the stern, with storage space for containers and various items of equipment.” WT
In war time, Louhi would be able to lay mines.
