Centrifugal Pump Overhaul Parts Package for VLCC Fleet

Project Overview

A tanker company managing 6 VLCCs required comprehensive overhaul parts for the ballast, bilge, and fire-fighting centrifugal pumps across their fleet. The previous OEM supplier had discontinued several part numbers, forcing the owner to find alternative sources.

Challenge

• Multiple pump models across the fleet — 4 different manufacturers represented
• OEM parts discontinued — reverse engineering required for some components
• DNV material certificates required for all wetted parts
• Coordination needed to deliver to 3 different ports (Singapore, Fujairah, Rotterdam)

Our Solution

Hicool compiled a master parts list across all 6 vessels and sourced from specialist pump component manufacturers:

• Impellers — duplex stainless steel (2205), CNC-machined to OEM drawings
• Wear rings — bronze CuSn12 with DNV 3.1 certificates
• Mechanical seals — John Crane compatible, SiC/SiC faces
• Shaft sleeves — Inconel 625 overlay on stainless steel base
• Bearing assemblies — SKF-equivalent, complete with housing

All parts were dimensionally inspected against OEM drawings, with deviation reports included in documentation.

Results

• 28-day consolidated delivery — all kits dispatched to 3 ports within the same week
• 45% cost saving vs. last available OEM pricing
• First 3 vessels overhauled — all pumps achieved or exceeded OEM performance specifications
• Annual supply agreement signed for ongoing pump maintenance parts

Key Takeaway

When OEM parts are discontinued, quality reverse engineering with proper material certification is the practical solution. Hicool's pump component sourcing covers major marine pump brands with parts manufactured to OEM tolerances and classification standards.
