Strategic needs: Ship operations & maintenance
1. Ensure reliability to minimise business risk & improve ship availability – Propulsion, Steering & Energy systems - high financial and HSE impact – Equipment which must be fully operational to fulfill Contract requirements
2. Improve maintenance planning & cost control – Be able to plan for maintenance intervention & operate
equipment based on known condition
3. Integrated information & management of critical systems – Simple, flexible & user-friendly - yet effective - monitoring systems
4. To extend class survey intervals and reduce need for dry-docking – Extend interval for main & intermediate class surveys & invasive visual inspections – Fleet / Ship CM program according to class rules

David Crane, Technical manager for Farstad: “We have had great success with this conditioning monitoring system over the years.
We have averted a number of major failures and resultant loss of hire or damage / injury through advanced warning of potential failures.
Not only are we able to avoid failures we can also minimise maintenance costs of larger electric motors by monitoring the bearing condition thereby extending service intervals greatly.”
