Drydock Services in Vietnam – Nationwide Ship Repair by HMS

HMS – Haiphong Marine Services provides professional drydock services in Vietnam for all types of vessels that require inspection, maintenance, or repair at any port or anchorage nationwide

Why Dry Docking Is Essential for Ship Repair and Vessel Maintenance

Dry docking is not only a mandatory requirement by international classification societies but also a strategic process for vessel servicing and operational performance. Key benefits include:

1. Enhanced Maritime Safety

Controlled surveys of hull, propulsion system, ballast tanks, steel structures, and welds.
Early detection of cracks, corrosion, and hidden defects minimizes the risk of failures at sea.

2. Optimized Performance and Fuel Efficiency

Hull cleaning, corrosion treatment, and propulsion system alignment reduce hydrodynamic resistance.
Lower drag results in measurable energy savings and reduced emissions.

3. Regulatory and Environmental Alignment

All restoration and evaluation work follow SOLAS, MARPOL, and rules issued by IACS, Vietnam Register (VR), ABS, DNV, ClassNK, and Lloyd’s Register.
Application of IMO-compliant protective coatings and energy-saving solutions supports green shipping initiatives.

4. Asset Protection and Preventive Care

Scheduled dry docking extends vessel lifespan, maintains commercial value for charter or resale, and avoids costly downtime.
Preventive measures reduce emergency corrective works and support continuous fleet operations.

5. Comprehensive Drydock Services in Vietnam

HMS provides integrated solutions including floating dock services, steel renewal, blasting and coating, machinery overhaul, and underwater works.
With access to major dry dock facilities across Vietnam, HMS supports nationwide ship repair in Vietnam with class survey support and standardized procedures.

For shipowners, dry docking represents a long-term investment in safety, compliance, and vessel performance. Choosing an experienced ship repair company in Vietnam ensures consistent vessel upkeep quality and operational readiness.

Case Study: Stern Gear and Propeller Repair at Pha Rung Shipyard – Haiphong

During a recent dry-docking project at Pha Rung Shipyard, Haiphong, HMS – Haiphong Marine Services performed a full overhaul of a 15,000 DWT general cargo vessel’s stern gear and propulsion system.

Scope of work included:

Propeller inspection and polishing: Restoring surface smoothness and reducing cavitation marks.
Rudder stock and bearing examination: Class surveyors verified clearances and wear-down readings according to LR class standards.
Stern tube seal renewal: Aft seal rings were renewed and bonding completed under controlled dry dock conditions.
Hull cleaning and anti-fouling coating: High-pressure washing to remove marine growth, followed by application of anti-fouling coatings.

The project was completed within seven days, minimizing off-hire time for the shipowner. Post-docking sea trials confirmed improved propulsion efficiency and reduced vibration, resulting in measurable fuel savings and smoother steering performance.
