Project Description
Ha Thanh Company is proud to have successfully completed the rubber lining project (Hot & Cold Bonding) for four acid storage tanks, as well as the associated piping and chemical pumping system, serving two specialized Platform Supply Vessels (PSVs) at the VARD shipyard, Dong Xuyen Industrial Park, Ba Ria – Vung Tau. This project is part of the Vard AS Group (Norway), with vessels exported to the Australian market.
With a total rubber lining area of up to 400m², the tanks and pipelines are specially designed to store and transport hazardous acids such as hydrochloric acid (HCl), phosphoric acid, industrial waste acids, and other dangerous liquid chemicals. These are among the largest HCl tank systems in the offshore supply vessel market, meeting the strictest international chemical safety standards, especially for the supply of cleaning solutions for equipment at oil and gas drilling wells.
In addition to traditional cargos (fuel, water, drilling mud, etc.), these PSVs are capable of transporting large quantities of hazardous and dangerous liquid chemicals, including MEG, TEG, NaOH, HCl, and H₂S scavenger compounds.
The two vessels for this project are named MMA Plover and MMA Brewster – modern ships built to international standards, ready to support offshore oil and gas activities in Australia.
This project once again affirms Ha Thanh’s capability, reputation, and standing in the field of protective rubber lining for chemical storage tanks, meeting the most demanding technical and industrial safety requirements.
