CASE STUDY

Diagnostic Prior to Rig Deputation Enabled ~$900,000 in Revenue Over 6 months and Saved ~$20,000 Due to Extension of Overhaul by 2000 hrs

Oil & Gas

Engine Condition Monitoring: Health Diagnostics

Caterpillar Diesel Engines

Repeated breakdowns on the 7 nos Caterpillar engines (Series 35 & 34) across the 11 land rigs
These breakdowns were impacting the drilling performance.
A local service provider advised Top End Overhaul on 3 nos. 3512 & some repair activities like injector replacement,
turbocharger replacement, cylinder head replacements on the other engines.

Neptunus’ expert advised for Engine Health Diagnostics using torsional vibration analysis. The objective was to ascertain the problem & recommend the optimal servicing and spare parts to prevent the breakdowns.
Neptunus’ team went onboard & carried out the engine health inspection through remote engine monitoring systems

Since MTBO was extended by 2000 hours (20% extension), life cycle cost was reduced by (⅕)*$50,000 per engine = $10,000
per engine, resulting in savings of $20,000 for two engines.
The repair saved 10 days compared to overhaul, and breakdowns were completely eliminated.
The drilling performance improved. Rigs were able to complete wells on time & the charterer extended the contract of one
rig by a period of 6 months .This enabled revenue of 180 days * $5,000 = $900,000
