Challenges for laid-up vessels
When vessels are taking out of operation and laid-up, the on-board equipment will experience situations they were not designed for. It is important to know the risks in this lay-up period, and what can be done to avoid oil systems problems when starting up the equipment again.
We’ve created this guide as a reminiscent of the challenges arising during cold and hot lay-up, providing some tips for maintenance as well as steps to do before re-commissioning. These im-portant steps are to avoid huge costs in connection with later stops or equipment breakdowns.
The main challenge with laid-up vessels is related to water content in oil, which
increases or change state/character. This can lead to severe damage when machinery and equipment are to be re-started.
Some machines are kept in operation, but a substantial part of the vessels equipment is not used.
It is this equipment that we need to be particularly aware of.
To avoid the challenges during hot lay-up we recommend continuous oil filtration and water removal. If this is
not done, and the lay-up period is longer than 14 days, it is very important that the oil is filtered thoroughly
before commissioning, in order to remove particles and water. For short lay-ups (under 2 months) you must be
particular conscious and ensure thorough oil filtration and water separation before running the oil systems again.
Electrically dead with no operating machineries. A situation which equipment is not designed for.
To avoid these challenges from the cold lay-up we recommend to run oil filtration and
water separation monthly or at least with an interval of maximum two month. It is very
important that this is done to avoid wear and breakdowns of machinery when they are
started up again.
Many shipping companies have had very unfortunate experiences and extraordinary expenses when laid-up vessels are put back in operation.
In a few cases, the problems occur immediately, but most often the failure manifest themselves when the equipment has been in operation for 2-3 weeks.
