PRESS RELEASE 9 MARCH 2018 – After two years of work, HELCOM today releases a comprehensive assessment of maritime activities in the Baltic Sea. The report covers a wide range human activities at sea, from commercial maritime traffic to leisure boating and from fisheries to hazardous submerged objects.
HELCOM releases today the most comprehensive assessment of maritime activities in the Baltic Sea region currently available – covering distribution of activities at sea, developments over time, related environmental issues as well as future perspectives and scenarios. The vast number of activities addressed include operational and accidental pollution from maritime traffic, fisheries, aquaculture, offshore energy production, cables and pipelines, submerged hazardous objects, and leisure boating.

A large part of the report is dedicated to maritime traffic – still the most common maritime activity in the Baltic Sea – and to mapping it on a regional scale. In terms of environmental effects, the report highlights that some types of ship-based pollution have already been effectively dealt with in the Baltic Sea over the last decades, including 90% reductions in both operational oil spills and sulphur oxide (SOx) emissions from ships exhaust gases.
For other types of ship-based pollution, recent decisions will result in more reductions in the near future. Those decisions include banning of untreated sewage discharges by 2021 and a requirement of 80% reduction of nitrogen oxide (NOx) emissions for new ships built 2021 or later.
However, some types of ship-based pollution remain unquantified, including litter, chemical residuals, and anti-fouling paints, and others, such as underwater sound, are yet to be addressed. The concluding chapter of the report explores future scenarios of maritime traffic and related environmental regulations.
Ship accidents in the Baltic Sea occurred at a fairly stable level of 300 accidents per year during the period 2011–2015, 4 % of which led to loss of life, serious injuries, or environmental damages. The coastal countries have relatively well-developed systems in place to prevent accidents by increasing safety of navigation.
As an example, nearly 200 000 km2 of seabed, more than the combined surface area of Estonia, Latvia and Lithuania, have been resurveyed between 2001 and 2016 by national hydrographic agencies in the Baltic Sea, bringing the accuracy of nautical charts to a new level.
The coastal countries also have response resources in place. However, new developments, such as carriage of modern low-sulphur fuels, require updates and new solutions for response procedures.
In other chapters, the assessment informs on developments such as the recent and upcoming increases in sea based aquaculture, wind power, and offshore oil and gas production. The chapter on hazardous submerged objects draws attention to the environmental hazards in the legacy of dumped and lost military material, wrecks, and industrial waste.
The report makes unprecedented use of the regional HELCOM Automatic Identification System (AIS) data, including high-resolution information on vessel movements in the entire sea basin since 2005. The extensive data is especially visible in the chapters related to maritime traffic and fisheries.
Besides presenting a large number of maps and illustrations, the report includes a detailed description of the methodology used to extract and create the presented information from raw AIS data.
The assessment also synthesises a number of other regional datasets on maritime activities in the Baltic Sea area stemming from regular national reporting to HELCOM. These cover issues such as spills observed via aerial surveillance, maritime accidents, response operations, port reception facilities, progress in hydrographic re-surveys, and aquaculture activities.
The 250-page report is the result of a two-year collaborative effort between the editorial team in the HELCOM Secretariat as well as national experts, providing review and additional material, and regional projects.
The report is intended to support the update of the "State of the Baltic Sea – Holistic Assessment" as well as to benefit the work of the relevant HELCOM Working Groups. It also enables the HELCOM Contracting Parties (Denmark, Estonia, European Union, Finland, Germany, Latvia, Lithuania, Poland, Russian Federation and Sweden) to demonstrate achievements, and plan future regional work, on the regional objective "Environmentally friendly maritime activities", agreed as part of the Baltic Sea Action Plan in 2007.
In addition to this traditional publication, a large number of GIS datasets generated in the process, particularly AIS based maps on maritime activities, are released simultaneously for the general public via the HELCOM Map and Data Service (MADS). These maps are anticipated to be interesting and useful for various purposes beyond HELCOM cooperation, including national maritime spatial planning and research. The code used in producing these datasets is also made available for the same purpose via the GitHub platform, to help similar initiatives within and beyond the region.

HELCOM is an intergovernmental organization
made up of the nine Baltic Sea coastal countries and the European Union.
Originally established in 1974, its primary aims as a governing body of the
Helsinki Convention (1974/1992) are to protect the marine environment of the
Baltic Sea from all sources of pollution, as well as to ensure safe maritime
navigation. The official name of HELCOM is the Baltic Marine Environment
works to address environmental effects of human activities on land and at sea.
Its working groups consist of national delegates and observers (industry and
civil society representatives). Groups dealing with measures to address
activities at sea include the HELCOM Maritime, Response, Fish and Pressure
drafting of an assessment of maritime activities in the Baltic Sea was agreed
by the coastal countries and EU during the 2013 HELCOM
Ministerial Meeting in Copenhagen.
