Vessel Condition monitoring services
Our main goal is to help ship operators maximize to the uptime of their vessels With condition monitoring. we can avoid unplanned and prolonged repair times,
thus reducing downtime and even maneuvering incapacity.”
Condition monitoring provides ship operators with valuable data on the condition
of the ship and establishes the basis for informed decisions on planning
maintenance measures and ordering spare parts in good time. This can
significantly improve the utilization and thus the profitability of the ship.
In day-to-day ship operations, structural and mechanical failures can cause
serious accidents, placing the crew and passengers on board in danger,
posing a threat to the environment, inflicting ship damage, and causing
considerable financial losses. Condition monitoring is gaining popularity in
the marine industry since is a more cost-efficient and effective maintenance
strategy that can save ships from the following. The use of condition
monitoring in on board ships enables the continuous monitoring of critical
onboard assets, such as main engines, thrusters, generators, compressors,
and pumps.
Wireless Vibration Sensor
A Wireless Vibration Sensor is a device that includes
an Accelerometer and is capable of measuring vibration and sending it to a
receiver using a Wireless protocol. Depending on the wireless protocol
used, some of these sensors may even transmit data in real time. Hence
having the capability to connect via peer to peer or mesh network.
Wireless Vibration Sensors are used today for multiple purposes, being
online Condition Monitoring the most important one. A big variety of
Wireless protocols allow Wireless Accelerometers to be used in multiple
ways replacing existing wired solutions. Bluetooth 5.0 mesh network
technology allows us to easily build big networks of sensors.
Cost Benefits of Vibration Analysis
The below chart indicates the cost benefit of implementing vibration analysis program in your company. Managing your assets without the vibration analysis program will cost you more than 15 times than the system with a strong predictive maintenance program.
Benefits of Vibration Analysis
- Reduces equipment costs
Instead of replacement of the entire piece of equipment due to critical failure, a repair is made prior to failure and cost is minimized to the price of the component and the labor needed for the repair.
- Reduces labor costs
When repairs are scheduled, the amount of time needed for repair is reduced because of a smaller number of component replacements instead of entire equipment replacement. Also, the frequency of repair for critical failure of equipment will be reduced and the amount of “critical callouts” will be greatly reduced.
- Reduces lost production time
Component only” replacement is scheduled along with production to take place during scheduled downtime. Unscheduled downtime may cost thousands of dollars per hour. A proactive maintenance department can head off critical failure downtime by scheduling repair during non-productive times.
- Increases safety
Predictive maintenance would allow potential problems to be fixed before failure occurs, which would create safer driving conditions for employees & customers, saves people life, assets, environment and company reputation.
- Increases revenue
With less maintenance on good components and quicker repair of faulty components, repairs can be more effectively handled, thereby reducing repair time.
- Increases efficiency of employee time
By identifying the precise repair task needed to correct deficiencies, as well as the parts, tools and support needed to correct the problem can dramatically increase effective “wrench time.”

We @ Rototech identify the root causes of your machinery vibration
- Unbalance – In the case of rotating equipment, the rotating mass must be equally balanced. An unbalance axis will create a centrifugal force which causes the machine to vibrate.
- Misalignment – A very common cause of vibration is due to misalignment of rotating shafts. Angular misalignment, parallel misalignment, soft foot and thermal expansions contribute to misalignment and high equipment vibrations.
- Wear – When components become overly worn they can cause vibration in machinery. Damaged areas of roller bearings or chipped gears can cause a machine to vibrate.
- Loose Connections – If a worn part does not become damaged over time it can easily become loose, thus causing vibration. The loose connections can become destructive very quickly, like loose mounts or anchors. Loose belts can cause fan vibrations.
- Auxiliary Equipment – The auxiliary equipment nearby main equipment can cause vibration on you equipment due to structural vibration transfer.
- Resonance – Resonance can cause high vibrations on your equipment. The piping and the structures connected to your equipment can cause vibrations if the natural frequency falls close to the equipment running speed. Cracks- Cracks on the equipment base and the other rotating parts can cause high vibration on your equipment.
