LNG Tanker Boiler Fan Repair

A client contacted us with an emergency repair project. A liquid natural gas (LNG) tanker was experiencing a possible boiler fan failure. The vessel was not allowed to dock for repairs due to safety concerns with the cargo and was held off shore.

It was determined that the boiler fan would require new bearings. Our technicians gathered the required parts as well as balancing equipment and laser alignment tools, and were ferried ship board to help make the repairs. A storm was approaching and the repairs would have to be completed quickly.

The blower was disassembled and the new bearings installed, the coupling was aligned, and the fan was dynamically balanced all within the requested time frame. Our people were ferried back to Boston and the ship was allowed in port to off load its cargo.

Emergency Repair of a Dust Collector Fan

Most rotating equipment at some point will experience some sort of failure. This can occur from damage due to wear or issues such as lubrication or vibration. In this case the customer experienced a rare catastrophic failure of a 200 horsepower dust collector fan.

The fan located on a large dust collection system had to be removed from location using a crane. A quick failure analysis determined that the fan wheel failed due to fatigued welds after years of use.  The failure caused significant damage to the fan housing and internal components of the fan. The housing required significant repair before a new fan wheel could be installed. Proper alignment and dynamic balancing was performed upon completion of the repair for a turnkey solution for our customer.

One of our customers needed a fan and motor assembly replaced on the top of their Delta cooling tower. The 30" fan and electric motor were located at the top of the 25' cooling tower, which would require the use of a crane to replace. With the crane in place, our technicians accessed the tower, tied off and removed all of the supporting hardware, allowing the rigger to crane the unit off the tower.

The new unit, which was prepared prior to the installation, was fully assembled and ready. Our preparation allowed for minimal crane use and a quick turnaround of the job.

Thermal Oxidizer Fan Repair

We were contacted by a manufacturer in Bloomfield, Connecticut who had experienced the failure of a Heat Recovery Fan for their Thermal Oxidizer. The repair was straightforward enough: remove and replace the bearings, replace the belts and perform laser alignment and dynamic balancing.  Unfortunately, the project had significant logistical constraints - the unit was only accessible via a very narrow ladder, it was located about 25 feet above the ground, and the bearings weighed about 30 pounds each.

The project required the use of a man lift to get the bearings and tools to and from the fan. We also had to remove and replace large bulky fan guards, as well as the belts, with very limited space to work with. Our skilled technicians, who possess years of experience, were able to safely make the repairs and get the customer's Oxidizer system up and running quickly.
