Refurbishment of Dredge Pump Casings-23 Dec 2022


Our field servicing team has successfully completed the machining scope for refurbishments of two dredge pump casings onboard. The work scope consists of machining off corroded flange surfaces, build-up material via welding and reinstate back to GD&T stated in the engineering drawings.

As the pump casing’s seal flanges are orientated at upright position, this posed higher challenges for conducting circular surface milling as well as the O ring grooving process. To achieve the tight tolerance stated in the drawings, API 3D laser tracker was deployed for dimension monitoring and post machining inspections.
