Comparing wired and wireless costs on crude oil carrier

The problem

Portable condition monitoring programs are used in the marine industry to obtain Class Exemption from frequent, onerous, walk-around inspections. Wireless technology can complement walk-around to track problem equipment more closely. However, a crude oil carrier – essentially a huge metal box -- offers a very difficult environment for wireless signals. The operator wanted proof that wireless could work.

The solution

The carrier installed SKF Multilog WMx wireless systems to collect complex dynamic vibration data from machines in the most difficult of locations. The back-haul of data to the host system used a mesh-network of access points throughout the vessel.

The result

The battery-powered SKF Multilog WMx systems have been successful in collecting repeated data in a challenging wireless environment. The additional data collected has been integrated with existing software and provides valuable information for improved reliability.
