Nordic Association of Marine Insurers (Cefor) presents post IMO 2020 experiences

06 May 2021

The Nordic Association of Marine Insurers (Cefor) in early April release a memo indicating its observations and conclusion of IMO 2020.

Overall, thought the shipping industry largely adapted to IMO 2020, Cefor observed the change has caused issues for some shipowners.

“No: there were incidents, some causing severe damage, and some claims were significant, due both to the cost of repairs and to loss of earnings while awaiting repairs, often because critical spare parts were not available from stock,” it learned.

“And quite a few owners have also told us of operational issues and smaller occurrences that did not turn into insurance claims.”

Cefor continued to share some observations it made from IMO 2020 regarding tank cleaning, filtering, lube oil, viscosity and stability.

Tank Cleaning

  • Questions arose concerning the disposal of the residue in the cleaned tanks


  • Observation has been made on a lack of crew control and understanding of how to maintain and establish the condition of the filter elements

Lube Oil

  • Lack of management, time and knowledge to determine current condition of engine piston rings and carry out maintenance before damage


  • New fuels typically come with viscosity of 2-3 cSt/50 degrees Celsius while engine typically takes between 10-15 cSt. Experience has been gain in adjusting temperature and viscosity of the material


  • The less stable post-IMO 2020 bunker fuels require planning, testing, competence and knowledge in handling

“Bunkering and the handling of marine fuels remain a complex issue, also post-IMO 2020. Complex issues require all of the stakeholders involved to co-operate, both to limit the number of problems that can be caused and to solve problems when they occur,” said the technical memo.

“It may be naïve to expect all the various stakeholders involved in fuel issues to agree, but when stakeholders do co-operate and communicate, openly and with integrity, the chances of both avoiding and handling situations better have much higher odds.

“The maritime industry has done well, but needs to be focused going forward. Until marine fuels are of a quality equal to what we expect from the petrol stations fuelling our (fossil-driven) cars, we all need to pay attention to marine fuels. Although claims numbers are not significantly higher, poor fuels and poor handling of fuels do constitute a significant risk for a vessel either on the high seas or in narrow waters.”
