What could possibly go wrong?? …well things do!
Root cause analysis is an effective tool for identifying organizational as well as structural issues.
The cost for downtime of sites is very high, therefore, time-to-response is essential.
Quick response time is key for solving issues in field, as is thet the technical know how needs to be wide. A core asset to do so is experience and deep technical knowledge. Having a such background has definitely helped a lot in meeting troubled customers worldwide. Being able to propose corrective action to customers just hours or days after site visits shows responsiveness that is highly valued in the telecom world. Below some highlights of field work I have done over the years.
Thermal Measurement
Site located three hours drive in to the djungle
Papua New Guinea / Solar Powered Telecom Sites.
The customer was building a few hundred sites without any grid power connection or generators, in very distant locations where most of the sites only could be accessed by helicopter. Half way in to the project time they discovered that they had some issues with already installed sites, primarily that the sites were going offline at night due to lack of power. During our investigation, we noted a long list of root causes, everything from installation errors to trees shading the solar panels and under dimensioned solar systems. After visiting seven sites, we were ready to present a corrective action report for these pressing issues, as well as an advanced energy availability report.
The energy availability report helped the customer to correctly dimension the equipment on site and a corrective action project was launched.
Voltage measurement
100% Renewable Energy Powered Sites
Roof Top Site, Baku
Overheating due to use outside specification
Baku Azerbaijan / Over Heating Telecom Sites.
Operator reported that they had severe problems with overheated sites and widely spread battery failures. During our week of investigating these issues, the OEM supplier and I visited 9 sites and to identify the problems. We concluded general installation mistakes and noted that some equipment was being used far outside of its specifications. These assessments lead to an upgrade proposal for the entire network.
Investigation Ongoing
Mexico, Tabasco Region / Thermal Runaway of Batteries.
After a thermal runaway in a battery system, me and my team went the site in a hurry to investigate the background. It took some time to figure it out, but after analyzing the results of lab test done in advance by the customer, we were able to concludelack of suitable routines and guidelines as a fundamental reason forthethermal runaway. The root cause of this event led to changes in the customer’s user guidelines for batteries
Backseat Report Generation
Anti theft measure using concrete.
Sao Paulo, Brazil / Theft of batteries from sites.
In recent years the theft of lead acid batteries from telecom sites has become a huge problem in field, South and Latin America, Africa and parts of South East Asia are very much exposed. After conducting studies in field, we gave recommendations for many measures to reduce the risk of theft, examples of such recommendations are new cabinet types and GPS tracking of batteries. Results of this commitment led to workshops in Sweden, Mexico, Brazil, India, Finland USA, and Colombia.
