Dataset

The dispersion of pollutants exhausted from a generic service offshore vessel are investigated in the closed-circuit atmospheric boundary layer wind tunnel (ABLWT) at Eindhoven University of Technology. The vessel is replicated at a geometric scaling ratio of 1:100 and exposed to maritime neutral atmospheric flow conditions. For most measurements, an approach flow velocity of 10 m/s (full-scale) is set at the exhaust height.

The majority of conducted measurements relate to 25% of maximum continuous rating (MCR) engine load, which results in a release velocity of Ue = 8.8 m/s (full-scale). Emissions are released from an exhaust with circular shaft of 0.76 m in diameter (De). To match the densimetric Froude number (Fr) in experiments, and reality, a velocity scaling ratio of 1:10 is chosen for the wind tunnel measurements.

Main focus of pollutant concentration measurements is set on locations at 1.5 m height on the vessel’s deck to assess the possibility of workers’ exposure to emitted pollutants.

Measurements are valid for the following conditions:

• Standard atmospheric conditions (15 degrees Celsius and 1013.25 hPa), resulting in an ambient air density of ρa = 1.225 kg/m3.

• Emission temperature of 350 degrees Celsius (corresponding to an emission density of 0.567 kg/m3)

This results in a densymetric Froude number of Fr = 4.396069 (based on the diameter of the exhaust stack (De) and Ue = 8.8 m/s.


In addition to the Metadata report, raw data time series of pollutant concentrations as well as appraoch flow conditions are provided here.
