Emergency Air Compressor Replacement for Container Vessel During Drydock

Project Overview

A Singapore-based vessel owner needed an emergency air compressor replaced on their 4,250 TEU container vessel during a scheduled drydock in China. The existing unit had failed its BV class survey, and the vessel could not leave drydock without a compliant replacement.

Challenge

Drydock time is expensive — every additional day costs the owner significant revenue loss and dock rental fees. The challenges were:

• BV Type Approval required — generic industrial compressors not acceptable
• Exact dimensional match needed for the existing engine room mounting
• Complete documentation for BV surveyor approval within days, not weeks
• The drydock had only 18 days remaining

Our Solution

Hicool identified a BV-approved emergency air compressor from stock at a partner manufacturer in Taizhou. Key actions:

• Day 1-2: Confirmed dimensional compatibility from GA drawings, verified BV Type Approval validity
• Day 3-8: Factory acceptance test with BV surveyor witness at manufacturer's facility
• Day 9-10: Packaging and documentation preparation (test reports, BV certificates, O&M manuals)
• Day 11-12: Trucked directly to the drydock

We also supplied a recommended spare parts kit (valve plates, gaskets, piston rings, oil filters) to support the vessel for the next 5 years of operation.

Results

• 12-day turnaround from order to delivery at drydock gate
• BV surveyor approved the installation on first inspection
• Vessel left drydock on schedule with no delays
• Spare parts kit valued at 15% of compressor cost — significant savings vs. OEM pricing

Key Takeaway

Drydock equipment replacements demand speed without compromising classification compliance. Hicool's network of pre-qualified manufacturers with existing Type Approvals allows us to source certified marine equipment in days rather than months.
