FAILURE: ROOT CAUSE ANALYSIS


SOLVING PROBLEMS… BEFORE THEY OCCUR


A root cause analysis discipline in the maritime sector can help transform a company`s engineering culture from being reactive to being proactive which has been shown to increase efficiency.


Marine engineering staff with this forward thinking mind set typically will have less unplanned vessel break downs and more reliable operational days for their fleet. The discipline in constantly striving to improve evermore complex vessel`s reliability and efficiency are understanding beforehand, what factors can cause an unplanned vessel breakdown and determine what preventative actions are needed to be taken to avoid one before they occur.


INTELLIGENT VESSEL DATA


The key to this is providing ‘intelligent vessel data’ for engineers and operation managers to be able to monitor the vessel information in real time combined with historical information at their fingertips with predictive maintenance alerts giving an early indicator when a component part may be near to failing.


The challenge for all roaming technical staff is providing the detailed alerts and historic information available for inspection, where ever they might be and even on their smart phone to enable an investigation to the root cause trends and thus develop their own maintenance policies for planned and routine maintenance for improved reliability and vessel efficiency.


PLANNED MAINTENANCE SYSTEM (PMS) One new solution that addresses this problem is a vessel PMS with an optional predictive maintenance alerts module combined with near real time remote vessel sensing intelligent remote asset monitoring solution (iRAMS) which offers information to enable the operator to ‘solve problems before they occur’.


When operating vessels offshore at maximum efficiency with a small crew, getting the right information at the right time to be able to identify a potential failure before it arises has been the traditional challenge for many CTV operators.


This wealth of vessel management information can be accessed pictorially or downloaded in CSV format with a useful report feature to be able to schedule them to be automatically emailed once a day/week/month etc. perhaps even direct to a client if required, reducing administration expenses.


More advanced dual parameters engine data is also available for example comparing fuel consumed against engine hours or engine load verses boost to providing a more detailed insight leading to identifying efficiency issues.


Vessel PMS applications has been widely adopted for many years in the larger fleets and is now understood however by integrating a new AST maritime remote sensing and engine diagnostic system, iRAMS with a Planned Management System (PMS) now offers a solution providing the right information at the right time for a vessel operating globally.


The picture below is a snap shot of the vessel engines data taken every 5 minutes and transmitted shore side to the iRAMS portal. The iRAMS reporting portal records and displays in near real time the entire vessel history for later investigation for root cause analysis providing very advanced and detailed reports on a variety of factors and parameters from single reports with a single parameter e.g. fuel consumption, temperature, RPM, oil pressure, boost etc. to more advanced dual parameters.
