0.1 percent survey reveals 'potentially critical issues'


New survey documents fuel segregation, filter choking and fuel pump seizure issues.



A DNV Petroleum Services (DNVPS) survey on the operational impact of the European Union 0.1% marine fuel sulphur limit – enforced on Jan 1 this year – has revealed potentially critical issues.

Among the 65 shipping companies that responded to the survey, 40 percent felt the EU member states were not harmonised in applying regulatory standards when verifying compliance with the 0.1% marine fuel sulphur limit.

According to DNVPS, this lack of uniformity could confuse and dampen the shipping community’s confidence in the ability of the EU to enforce its own environmental regulations.

“DNV had previously expressed concerns that the 0.1% sulphur cap effectively meant ships at berth in the community ports must use marine gas oil, notwithstanding many of the boilers on board would not have been modified by Jan 1 to burn this type of fuel,” said DNVPS managing director Tore Morten Wetterhus.

“Now that more ships are presumably equipped with the installations to minimize gas oil-related risks, such as fuel pump leakage and boiler explosion, shipboard personnel face new worries not knowing what to expect from port state inspections in different EU ports,” added Wetterhus.

Close to 40% of the respondents said their vessels did not have the tank flexibility to segregate gas oil and heavy fuel oil. Another 15% reported filter choking and fuel pump seizures when switching from normal sulphur heavy fuel oil to the much more expensive gas oil on entering the EU community ports.

Surprisingly, almost a third of the respondents did not routinely test the quality of their gas oil purchases, despite the risks of their ships consuming fuels not compliant with the 0.1% fuel sulphur limit.

In the worst case, an untested fuel could be so severely ‘off-specification’ that it causes substantial engine damage and jeopardizes the safety of crew and cargo at sea, DNVPS said.

“As a marine fuel management company, it is especially unsettling for DNVPS to find that some ship operators are gambling with safety when they choose to use gas oil of unknown quality. There must be much more awareness on problems commonly associated with this type of fuel; for instance, low flashpoint and low viscosity,” Wetterhus cautioned.

On a brighter note, he said 90% of the survey respondents believed their crews were familiar with the onboard routines for complying with the EU fuel regulations, but many also felt continuous training would be necessary.

To update the shipping community on marine fuel regulations, related operational challenges, and the latest changes to the ISO 8217 marine fuel specification, DNVPS has been organising seminars and round-table discussions in its key markets. Targeted locations include Singapore, the Netherlands, Norway, Greece, Germany, Dubai, USA and Canada.
