Surveillance of Sulfur Fuel Content in Ships at the Great Belt Bridge 2019
Rapport, 2020
In the period January 2018 to November 2018, 3580 valid sniffer measurements of individual ships were carried out at the Great Belt Bridge (medium and good quality). The precision of the fixed sniffer is estimated as ±0.04 FSC % (1σ) with an estimated systematic bias of - 0.074 % FSC for the measurements in 2018, based on comparisons with port state control authorities. Therefore, only ships running with an FSC of 0.18 % or higher can be detected as noncompliant ships with confidence limit of 95 % by the fixed sniffer system, when accounting for the bias. The data for the period January to November show a compliance rate of 95.3 %.
Here 1.1 % of the ships were in gross non-compliance with the EU sulfur directive with values above 0.5 %. Additional 0.8 % of the ships were measured in the FSC interval 0.3-0.5 % while the rest had values below 0.3%. There are differences over time, with the highest values in the summer. On several occasions we encountered one specific ship that was non-compliant with respect to the EU sulfur directive and which was equipped with a scrubber that was being commissioned.
