Norwegian domestic regulations
The Environmental Agreement (NOx Fund in Norway when trading domestic).
The Environmental Agreement on NOx 2011-2017 was signed on the 14th of December 2010
by 15 business organisations and the Ministry of the Environment.
The agreement is an extension of the the Environmental Agreement on NOx for the period
2008-2010. The Environmental Agreement - and the Participant Agreement - constitutes the
framework for the efforts of the Business Sector’s NOx Fund.
Through this Agreement, the Business Organisations shall facilitate concrete reductions
of the nitrogen oxide gases harmful to the environment. Undertakings which sign the
Agreement will be exempt from paying NOx tax in return for their commitment to the
obligations laid down by the Business Sector’s NOx Fund whose primary task is to
provide funding for NOx reducing measures.
The Agreements are important contributions to meet Norway’s commitments in the
Gothenburg Protocol for 2010 and the future NOx commitments Norway will receive in 2020.
In addition, the work ensures improved calculations on NOx emissions.
The Environmental Agreement 2011-2017
In total, the Business organisations shall facilitate emission reductions stipulated in the Agreement 2011-2017 to
16,000 tonnes of NOx, as well as maintain the effect of the obtained emission reductions for the entire period.
The Agreement has for this period both yearly and two-year goals to fulfil.

Gas fuel bunkering process
Liquefied Natural Gas (LNG) is bunkered by pressure from :
1) land based stations or
2) tanker trucks or
3) coastal tankers or
4) future bunker barges

Main gas supply
1. Double walled Gas Supply pipes from LNG tank to combustion chamber
2. Gas detection in outer pipe system (ventilated 30 times per hour)
3. “Block and bleed” valves stops all gas supply to the engine, if unexpected stop occurs
4. Gas detection system above the engine according to class requirement.

Summary
Summary
•
•
•
•
Marine Gas engines represents well proven technology.
LNG is available – increased demand will ensure even better
distribution network.
Dual fuel engines are the choice when enough LNG cannot be
carried to complete the voyage.
Where the application allows single fuel marine gas engines:
• More efficient
• Less expensive in terms of operating and life cycle cost.
• Lower emissions,
• Less complex engine supporting systems.
• Green profile for the ship owner – marketing tool.
• Lower lube comsumption
• Lesser or no sludge
• No oil spil during bunker operation
• Better working environment for engine crew
