Neptunus has been our preferred partner for the engine and z-peller servicing because of their quick response, excellent workmanship and customer-centric approach. In July 2019 in spite of the extremely harsh weather conditions, Neptunus’ service team responded to our urgent call and reached onboard our vessel Ocean Quest for thorough inspection of the z-peller assembly. We acknowledge their timely help and appreciate the team’s commitment.

Since implementing Vib360, it has become an invaluable resource in our Operations & Maintenance (O&M) strategy. The system has consistently provided early warnings of engine knocking, allowing us to address the issue before it escalates.
Thanks to early detection, we are now able to renew spark plugs on time, which has saved us from frequent breakdowns of expensive spark plug leads, a problem we faced often in the past. Vib360 has allowed us to optimize maintenance schedules, avoiding costly repairs and extending the lifespan of key components.

We are delighted with the overall performance & quality of Neptunus’s Oil Quality Management System. It has helped us in saving lube oil cost while enhancing the engine reliability. Considering the value this solution has delivered & the technical support extended by Neptunus, we are now in process of implementing the above solution across our fleet of Caterpillar engines onboard different drilling rigs.

The health checkup was done using the highly advanced Engine condition monitoring system The vessels are fitted with Niigata Main Engine and Z Pellet (Propulsion system). The system seem to be capable to predict failures in advance. Lastly, we found the Neptunus team knowledgeable and helpful in letting us know how to read the reports and what does each indicator means.
