Halliday Engineering recently completed repairs on LPG tanker, MV Gaschem Odyssey, onboard with the specialist skills of our project managers and qualified trades.

Halliday Engineering are proud to have recently carried out emergency main propulsion repairs on a 5,494 tonne LPG tanker.

Initial Scope:

Our client reached out with an urgent need to replace a cracked coupling onboard vessel GASCHEM ODYSSEY. The coupling formed part of the Controlled Pitch Propeller (CPP) propulsion system, and without its replacement the vessel could become inoperable.

Upon conducting an urgent on-site examination, the Halliday team promptly mobilised onsite the following day, aiming to complete the complex project within a 3-week period.

Manufacturers components were quickly transported by air from Germany to our workshop. Following this, we conducted thorough examinations with an on-site specialist before moving them to the ship at Botany.

This specific undertaking proved to be a significant hurdle for our team. We managed to successfully execute all the necessary in-water repairs, thereby circumventing the high-cost delays associated with taking the vessel into drydock.

Time-critical repairs

 Works Included:

  • Trimming the vessel utilising ballast tanks and installing over 100 tonnes of water bags to the bow of the vessel. This enabled access to the stern tube, propeller, propeller shaft and rudder.
  • Removal of the shaft generator and dismantle of the existing cracked coupling.
  • Removal of the intermediate shaft that connected to the main engine.
  • Disconnection of the rudder stops (enabling rudder to be rotated 90 degrees).
  • Moving the main propulsion shaft (complete with propeller) 1.5m AFT of the vessel, to allow space for new coupling to be installed.
  • Installation of new coupling with specialist Hi-torque calibrated tooling.
  • Re-assembly of all removed components and testing.

We worked closely on site with the OEM technician for key parts of the job and were fortunate to partner with established industry partners such as Tefol and Ausbarge whose contribution was crucial.

Technical Superintendent for Gaschem Odysssey, Tomasz Rybak quoted:
The exchange of cracked coupling flange of Gaschem Odyssey was a very complicated project and required professional but also flexible approach.
I am impressed with skills of your Engineering Team. Chris Bradley helped us properly assess complicated tasks and support with his knowledge of local market. Whatever tool / device, we have had required - was provided on short notice, which is highly appreciated.
Your workshop is very well equipped and the proper safety standards there are very well implemented.
We have 3 sister ships employed in Australian trade and Halliday Engineering will be always considered first if assistance in any repairs will be required.
