More and more ships are being fitted with scrubbers so that they can use cheaper, heavy fuel without violating regulations. But, there is a problem: inadequately protected mild steel is easily corroded by the highly acidic wastewater. Corrosion of the scrubber overboard pipe is a threat to the integrity of the hull. This often occurs between drydocking. The question is how to effect a repair without going to drydock or going off-hire.
Hydrex and sister company Subsea Industries solved this problem in 2019. We developed procedures to replace the final section of pipe with the ship afloat and without interrupting its schedule. We also developed a proprietary and patented method of preventing the same trouble from recurring.
This technique has been implemented successfully on close to 90 scrubber overboard pipes for some thirty different shipping companies to date – container ships, bulkers, tankers and reefers.
