ShipTRASE 
Swedish project 
= To comprehensively 
quantify and evaluate the 
effects of a range of 
potential emission reduction 
solutions for shipping in 
Europe, and 
= to develop more effective 
strategies and measures to 
reduce the environmental 
impacts of shipping 
To reduce ship-based 
emissions through optimized 
and extended EGCS to 
protect the atmospheric and 
maritime environment. 
Specific goals related to 
zGCS discharge water: 
ı Compliance with 
environmental standards in 
:he field of water policy 
(2008/105/EC) and the WFD 
= Turbidity value < 25 NTU 
To analyse the ecological, 
economic and legal aspects 
of both short and long-term 
measures to reduce ship 
emissions and 
zorresponding control 
mechanisms. 
To draw conclusions about 
environmental and 
economic effects of EGCS 
discharge water based on 
recompilation of information 
and to review the “2015 
zGCS Guidelines”.. 
Activities 
Related to EGCS discharge 
water: 
= Chemical characterization 
= Ecotoxicological tests 
= Modelling of 
environmental 
concentrations 
Related to EGCS discharge 
water: 
ı Treatment of water on 
board 
ı Analysis of the particles for 
organic pollutants (e.g. 
DAHs), metal residues, 
elementary composition and 
ecotoxicological hazard 
ovotential 
The effects of EGCS 
discharge water and LNG on 
“he uppermost water layers 
'e.g. in the trace gas cycling) 
will be investigated in the 
aboratory and compared to 
:onventional ship propulsion 
amissions. 
=» Literature review on EGCS 
discharge water 
composition, 
ecotoxicological and 
economic effects 
» Ecotoxicological studies (if 
:ime and resources are 
enough) 
ı Review of the legal 
“ramework regarding EGCS 
discharge water and water 
discharges. 
The project addresses both 
air and water emissions, 
including other waste 
streams such as wastewater, 
oil leaks, antifouling paint 
residues, food waste 
nutrients).

ImpEx 
To support the international 
discussions on the regulation 
of discharge water from 
EGCS. Hereby the scientific 
results obtained in the 
framework of the project, 
which take the concerns of 
marine environmental 
protection into account, 
shall contribute to a factual 
discussion. 
= Review status quo (this 
‚eport) 
ı Sampling campaign on 
J0ard ships 
ı Chemical characterization 
» Ecotoxicological tests 
= Environmental risk 
assessment
