Condition monitoring for DOF (bildenavn DOF)
DOF is a shipping company for whom it is important to use the most cost-efficient maintenance solutions. The company, headquartered in Austevoll, uses condition-based maintenance on critical machinery on board their ships. This maintenance philosophy requires reliable and cost-effective condition monitoring.
Karsten Moholt AS is an approved service provider of condition monitoring in the form of vibration measurements and analysis. Both DNV GL and ABS have issued approvals. We deliver, install and implement systems for vibration measurement and monitoring. This allows us to perform remote diagnoses of measurement data and reports.
Condition-based maintenance greatly reduces unnecessary maintenance and prevents breakdowns, which in turn cuts costs for DOF as a customer.
“DOF uses online and offline measurements of critical equipment to detect damages early and avoid breakdowns. Vibration measurements are also part of our strategy for condition-based maintenance on thrusters and other critical equipment.”
– Ole K. Nordbø. Technical Manager, DOF Management AS
Overhaul of EX motors for COSL
COSL needed to recertify and document that their rigs COSL Innovator and COSL Pioneer were in accordance with relevant standards and government requirements. To achieve this Karsten Moholt overhauled and repaired the Ex motors on the rigs both on site and in our workshop at Askøy. We solved the customer’s challenges quickly and according to the relevant standards and government requirements. Without the work carried out by Karsten Moholt, COSL would not be able to maintain technical and safety requirements and continue to operate as planned.
“Karsten Moholt were responsible for overhauling the Ex motors at COSL Innovator and COSL Pioneer in December 2017. The job was completed within the agreed time, cost and was of good quality.”
– Lage Nordby, VP Operations, COSL Drilling Europe AS
Express chairlift repair during winter holiday in Myrkdalen.
Myrkdalen is a very popular area for skiing and the chairlift is an important part of the infrastructure at Myrkdalen Fjellheiser AS.
The motor was dismantled on site and shipped to Karsten Moholt AS, where a team of skilled professionals was ready to diagnose it to determine if it could be repaired.
After carrying out electrical and mechanical condition monitoring, cleaning and drying the rotor and stator, the necessary parts were ordered with express delivery. Mechanical repairs were carried out and the motor was reassembled and tested.
Our customer received the motor at 25:15 on Thursday evening and the staff at Karsten Moholt could go home, knowing that the job had been carried out in the best and fastest way for the customer.
What initially looked like a total breakdown for the chairlift motor ended up – due to expertise, ownership and focus on the customer – as a story with a happy ending for Myrkdalen Fjelllheiser AS and their skiing guests. The normal delivery time for a new motor would have been 12 weeks.
