Plan and progress

Sub Project 1 - Fuels

Alternative fuels and technologies to meet IMO Tier III, focus on HFO, MGO and LNG

Objective:

The main objective of this study is to perform a full economic, technical and environmental due diligence of the alternative fuels and abatements technologies. This also includes assessment of technology trends and future legislation development.

Background and motivation

Requirement of 0.1% sulphur in the SECA's were put into force 1st of January 2015 and requirement of stricter limits on NOx emission for new built ships will come (1st of January 2016 in USA and Canada and later in European waters)

The known emission limits can be met by alternative fuels like LNG, low sulphur fuel oil with SCR or by HFO applying scrubbing technology and means to reduce NOx. There is a focus of Green House Gas (GHG) emission from ships even though there are no limits for the shipping industry. To make an objective comparison between different fuels and machinery systems, energy consumption analysis form well to propeller should be included.

This study will perform a full economic and environmental due diligence of the different alterative solutions. The study will be supported with data and experience form ships in operation

Tasks and activities


1. Perform energy analysis for the different fuels (from well to propeller)
2. Perform cost and energy analysis for abatement technologies
3. Feedback for ships in operation in different market segments: a) Short sea b) Deep sea
4. A case study on a ship operating in SECA area on HFO with scrubbing system for shulphur reduction and combined with EGR to meet NOx Tier III will be performed (Clipper Harald)
5. Comparison between ships with different technology level for stating the validity of the case results
6. A case study on a ship in short sea operation on Gas Only and Dual Fuel with LNG as the main fuel. A complete measurement program of exhaust emissions and fuel efficiency will be performed (With Marine, Irland)

Clipper Harald, Scrubber and EGR

Initial exhaust gas measurement performed
Need upgrading, delayed measurement fase 2 to Q3
Increase of EGR capacity
Adjustment of scrubber
Change of air cooler

With Marine, pure gas operation

Initial exhaust gas measurement performed
Fase 2 planned in Q3

Irland, Dual fuel operation

Initial exhaust gas measurement planned in Q3

LCA analyses are initiated

Deliverables:

1. Well to Propeller analysis
2. Measurement report from ship case study
3. Journal papers
4. Conference presentations
5. Main report summarizing the project
