Replacement of a firefighting main
Replacement of corroded sections of the firefighting main, with workshop prefabrication and hydrostatic testing.
Execution
The sequence applied and the engineering decisions taken
The order below reproduces how the work was actually carried out, including the points where the condition found required a change of scope.
- Dimensional survey on site with routing and interferences detailed.
- Spools prefabricated in the workshop, with welding and testing carried out off the vessel.
- Controlled removal of the corroded sections, with adjacent areas protected.
- Installation of the new lines with the minimum of welding on board.
- Hydrostatic test with pressure and hold time recorded.
- Identification, permanent supports and painting to the applicable scheme.
Comparison
Condition before and after the intervention
Drag the slider to switch between the two recorded conditions.
- Before
- Sections of the main with advanced corrosion found at inspection.
- After
- Main replaced, hydrostatically tested, identified and painted.
Result
What the intervention delivered
The main was handed over having passed its hydrostatic test within the docking schedule. Workshop prefabrication reduced the work carried out on board and the time spent alongside the other active work fronts on the vessel.
