Recently, one of our customers faced an issue with finding the acceptable alignment plan. The problem was in controversial DNVGL lubrication criteria conditions for low speed and full speed criterion, it was hard to find an alignment design that meets both criteria. However, our support team successfully helped to find the aft most stern tube …
Today we are honored to celebrate the regular “Update Day”. New ShaftDesigner update has been already delivered to our customers! The last three months were really productive for our team, despite the remote work. There are a lot of new features in the update, including customers’ requests. Also, some reported bugs were fixed.
The procedure of the water jet installation shaft alignment was to place the gearbox relative to the main shaft according to developed shaft alignment plan. The spatial position of the gear box was defined taking into account the gearbox manufacturer’s restriction on the loads coming from the shafting. The job looks simple if the distance …
The maritime community is concerned about frequent stern tube bearing failures. ROG Ship Repair company has organized an online webinar and further open discussion related to this issue. Intellectual Maritime Technology was honoured to open the webinar. Dr. Yuriy Batrak and Aleksandr Ursolov presented the key problems of preventing stern tube bearings failures at …
While most of the Intellectual Maritime Technologies team works from home, we didn’t lose efficiency. Recently our users have obtained next ShaftDesigner software updates (1.9.21–1.9.23) implementing a series of new helpful functions and some bug fixing. Some of the juiciest features are summarized below. Base model The ShaftDesigner software has expanded the repository …
A cargo vessel propulsion system torsional vibration calculation has been delivered to our customer! Some of the data was not provided by the manufacturer, but experienced IMT team filled the gaps by the statistical data and additional preliminary calculations. The standard Class recommendation for torsional vibratory loads from 3-blade propeller was too big for this …
The customer’s requirement was to provide the zero moment and shear force in all couplings. We developed the special calculation that searches for the bearings vertical offsets solution in order to provide such conditions. The ShaftDesigner software is unique in this; it holds all calculations together based on the single model. Of course, the user …
Another successful project is completed by our team while in quarantine! This time it was a tug’s Torsional Vibration Calculation. The project included four-stroke diesel engine, flexible coupling, gearbox, propeller shaft and five-blade propeller. Despite the lack of all information about the installation, our experienced engineers managed to fill the missing parts with help of …
The ShaftDesigner software is continuously improved even in the quarantine conditions. We just updated our users with new 1.9.20 version of ShaftDesigner. The main changes took place in the Torsional Vibration module: new torque-dependent acceptance criteria for vibratory torque and power loss; reducing pressure at a cylinder on a constant value; orders information in …
It was really efficient February for IMT! Yesterday we updated our costumers with the next ShaftDesigner 1.9.19 version after implementing their requests and improve the software. The most critical improvements are significant speed-up of vibrations calculation due to more efficiently using system resources, at least 2 times on heavy projects. We also continue to …
