The 'Waasmunster' is one of the most modern mid-size LPG tankers afloat today, and is operated by Antwerp-based Exmar. She arrived at Damen Shiprepair Vlissingen (DSVl) in January 2017 for the installation of a new open-loop Exhaust Gas Cleaning system (‘scrubber’) fitted inside a new funnel.

Planning ahead

Down time for the 174-metre vessel was minimised as, during a visit to the yard the previous summer, the necessary preparatory work in the engine room relating to cabling and piping had been undertaken. Also, in the months before her arrival in January the new funnel with the scrubber installation was fabricated in the no.2 workshop at the nearby Damen Schelde Naval Shipbuilding (DSNS). It was then convenient for it to remain there for the lifting and installation onboard including electrical systems, cabling and pipework.

Team effort

In addition to the collaboration with DSNS, another member of the Damen Shipyards Group, Damen Shiprepair Harbour & Voyage, also contributed to the project by supplying the GRE pipes that handle the highly corrosive waste products. External suppliers involved included PCN (steel pipes), FMJ (electrics) and Kranendonk (insulation). Following painting the completed funnel section was then transported from Workshop no. 2 to the 'Waasmunster' alongside at DSVl by lifting specialist Sarens. There, CNR (formerly known as Termiso) took care of the additional steelworks required on board during installation. The final painting was done by Den Breejen.

Complex connection

The welding of the funnel to the superstructure took eight days and altogether the 'Waasmunster' spent 25 days in Damen Shiprepair Vlissingen for the installation plus preparatory works. Various challenges presented themselves and were resolved through the dedication of the project team. The 'Waasmunster' departed on schedule on Sunday 5th February.
