Case Study: Vessel ROSEWOOD – Seawater Pipeline Replacement at Cam Pha Anchorage

During a routine inspection on the vessel ROSEWOOD, a leakage was discovered in the common outlet pipelines connected to the main seawater cooling pumps no. 1 and 2, located on the starboard side of the engine room. This presented a serious concern, especially under classification society regulations.

Bacviet Company was tasked with the removal and replacement of the defective seawater and overboard pipelines, including all necessary fittings, welding, testing, and certification.

Scope of Work Included:

• Dismantling of damaged seawater cooling outlet pipelines.
• Fabrication and installation of new seamless steel pipes (schedule 60), including elbows and reducers, fully meeting ABS material standards.
• All butt welding was carried out by ABS-certified welders, following an ABS-approved Welding Procedure Specification (WPS).
• Non-Destructive Testing (NDT) using Ultrasonic Testing (UT) was performed, as directed by the attending ABS surveyor.
• All pipe spools underwent hydrostatic pressure testing at 1.2 to 1.5 times the system’s safe working pressure, ensuring system integrity.
• After installation, all pipes were painted with two protective coats, using paint provided by the vessel.
• All gaskets, bolts, and nuts used were supplied by Bacviet’s workshop, ensuring quality and traceability.
• Complete logistics management, including onshore and offshore transportation, job permits, boarding passes, and customs clearance, was handled by Bacviet to enable seamless job execution.

This critical piping repair was successfully completed at Cam Pha anchorage, without requiring the vessel to move to a repair yard—minimizing downtime and avoiding costly delays.

Importance of Seawater Cooling and Overboard Pipe Systems

Onboard piping systems—especially seawater inlet and outlet pipelines, and overboard discharge lines—play a vital role in the operation of main engines, auxiliary systems, and HVAC units. Any failure or leakage in these systems can lead to engine overheating, environmental violations, or non-compliance with class standards.

Over time, marine pipelines suffer from corrosion, metal fatigue, and erosion, especially in high-flow seawater applications. Regular inspections and timely repairs or replacements are crucial to maintain safety and operational readiness.

Bacviet Company offers comprehensive marine piping services, including:

• Seawater cooling pipe replacement
• Overboard discharge pipe repair
• Engine room pipeline modification
• Class-approved welding and testing
• Mobile offshore and anchorage repair teams
