Replacement Casting for the FSO Jasmine, Reported in Metal Casting Technologies
A September 2014 country technical report in Metal Casting Technologies – Asia Pacific described Speed 3D Mold's work on a corroded cooling-system end cover from the FSO Jasmine, where the replacement geometry was recovered by on-site 3D scanning and the moulds were produced by 3D sand printing rather than by pattern making.

Why the component had to be reverse engineered
Marine and offshore equipment is often kept in service long after the original manufacturing information has been lost or the supplier has stopped supporting the component. The article describes a corroded cooling-system end cover aboard the FSO Jasmine as a component that had to be reproduced from the physical part itself through reverse engineering, because no usable pattern or production data was available.
Capturing the geometry on site by 3D scanning meant the replacement could be defined from measured surfaces rather than assumed nominal dimensions — the same starting point used for replacement casting work today.

The replacement route described
- 01
On-site assessment and scanning
The article reports that the existing corroded component was captured by 3D scanning on site, so the replacement geometry was derived from the part as installed rather than from drawings that were not available.
- 02
Digital geometry preparation
The scan data was used to prepare a digital model of the component suitable for mould design, following the same reverse-engineering route used for replacement work today.
- 03
3D sand printed moulds
Moulds were produced directly from the digital data by binder-jet sand printing, removing the pattern-making step that normally governs lead time on one-off replacement components.
- 04
Mould assembly and casting
The printed mould sections were assembled and cast to produce the replacement end cover and the related castings shown in the published figures.
