In basic terms, the cost of an oil tanker or a cruise ship being deployed justifies the cost of monitoring it.
Over the last few years with pressure being put on ship owners to ensure that they meet deadlines, there is a growing need to apply techniques to ensure that the condition of the ship and its associated plant is monitored.
Vibration monitoring has established itself as a proven condition monitoring technique. A typical example of machinery that has to be monitored includes cargo pumps, turbochargers, Azipods, ventilation fans and on cruise ships the building services area.
Protecting fans, pumps and motors
All rotating parts of a fan, pump or motor can be monitored using accelerometers. The output can be connected either back to a local control panel or to a portable data collector. The system enables the condition of the bearing, impeller or fan to be monitored.
One of the biggest problems encountered when monitoring vibration on board a ship is that the ship has no earth and as a consequence, special conditions have had to be applied to the installation.
Instrinsically safe accelerometers
Other considerations that should be made on a ship are the areas of classification, for example, on an oil tanker some of the cargo pumps could well require intrinsically safe accelerometers connected via a safety barrier to the safe areas.
Within the Hansford Sensors industrial accelerometer range, there are several products that can be used in the marine industry. The standard AC sensors (HS-100 Series) provides a 100mV/g output that can be connected back via switch/connection boxes (HS-BE) enabling a data collector to be connected.
Some of the applications, for example a turbocharger, require a high temperature sensor (HS-105 Series) to be used and connected back to a local connection box or back via multi-core to a more sophisticated analytical system.
