This step establishes the context of a hypothetical decision problem of evaluating and selecting abatement measures to the fleet of Grieg Shipping Group.
Grieg Shipping Group operates a fleet of 27 ships in total . The standard ship is an open hatch bulk carrier of ca. 47.000 DWT. The company’s vessels are categorized in 9 groups of sister ships where the oldest (A-class) are from 1985 and the newest (K

Configuration of alternatives
Table 3: Overview of the actual decision problem context
Problem Identify a priority list of abatement measures for the reduction of carbon emissions from the Grieg ships People involved Operation managers, superintendent, project engineers, crew,
ship management, QA-department, purchase dept., board.
Context Project EMISOL, Project Low Carbon Shipping
Time Limited, project duration 6 months with possibility for email and
phone communication. One week at shipowner’s office
What is specified as Result goals
A ranking of preferred abatement measures and a presentation of barriers for implementation
What is specified as Benefit goals
Raising awareness and knowledge of abatement measures to reduce GHG-emissions both towards decision makers and participants in the study.
Identification of alternatives
Brainstorm, discussion, internet searches and finally limited by the cost data availability
Identification of criteria Identified by student and Senior Project Engineer together
Score performance Subjective scores, directly rated by participants, cost data estimation provided by DNV Weighting of criteria Swing rankings made by participants
