Objective
The DNV EMERGENCY RESPONSE SERVICES (ERS) and the Class Notation CLEAN will be developed to include necessary requirements and features for operation in arctic areas.

Background
The DNV Emergency Response Service covers calculation of damage stability and longitudinal strength in an Emergency Response Situation. An Emergency Response Situation is defined to exist if the vessel has suffered damage caused by collision, grounding, structural breakdown, fire, explosion or other similar situation, such that the vessel's stability, strength and sea worthiness is impaired, or where serious oil spills may be expected.

The voluntary class notation CLEAN includes measures to reduce environmental consequences. Design and construction alone will not ensure best environmental practice. The thinking needs to be incorporated in crew's attitudes and practices. For this reason CLEAN and CLEAN DESIGN notations include requirements for operational procedures, such as log-books etc., in addition to technical design and built-in features.

Goal
The first phase will be to identify the need for additional content and specify how they can be adapted to use in arctic areas. The second phase will be to develop the notations and service including use of information made available trough the other work packages. Demonstrate (pilot) an Arctic Emergency Response service (AERS), using monitored data, cold climate data and new models.
