Cement Hatch Cover Cutting & Re-Welding Service in Vietnam

Professional Funnel Fabrication, Certified Welding & Marine Compliance

Vietnam is one of Southeast Asia’s largest cement exporting countries. Bulk carriers calling cement terminals such as Cam Pha Anchorage, Cai Lan Port, Cua Lo Port, Vissai Port, and Nghi Son Port frequently require temporary hatch cover modification to allow controlled cement pouring into cargo holds.

Because cement is loaded through pipeline or funnel systems, many vessels must cut dedicated loading holes on hatch covers and reinstate them after cargo completion. This operation requires technical precision, structural awareness, and compliance with marine standards.

Bacviet Shiprepair provides complete cement hatch cover cutting and re-welding services across Vietnam ports, ensuring safe cargo loading while preserving structural strength and watertight integrity.

Determination of cutting position onboard
Cutting of cement holes on upper and lower hatch plates
Fabrication of coaming around cutting area
Semi-automatic structural re-welding
Ultrasonic Testing (UT)
Vacuum watertight testing
Hot work permit arrangement
Transportation and offshore logistics
Standby support during cargo loading

All operations are carried out under approved Welding Procedure Specifications (WPS) and marine safety requirements.

Workshop Funnel Fabrication – Minimizing Onboard Risk

Before boarding the vessel, Bacviet fabricates a dedicated cement loading funnel in our workshop.

Pre-fabrication provides several advantages:

Precise dimension control
Strong structural alignment
Reduced onboard hot work duration
Faster installation during port stay

By preparing components ashore, we help vessels shorten repair time at anchorage or berth, minimizing demurrage exposure.

Controlled Hatch Cover Cutting Procedure

Hatch covers are primary structural components of a vessel. Any modification must avoid weakening stiffeners or affecting load distribution.

Before cutting, our team:

Verifies plate thickness
Identifies structural beams and reinforcements
Confirms cutting position with Master
Marks boundaries precisely

Controlled flame or plasma cutting is then performed to:

Prevent plate distortion
Control heat affected zone
Protect surrounding structure

Removed steel sections are preserved for accurate reinstallation after loading completion.

Fabrication of Coaming for Safe Loading Operation

To ensure safe cement pouring, a steel coaming is fabricated around the cutting hole.

This improves:

Flow control during cement transfer
Protection of hatch surface
Reduction of cargo spillage
Temporary sealing control during rain

Additional silicone sealing and tarpaulin protection can be arranged in adverse weather conditions at anchorage.

Certified Re-Welding & Structural Restoration

After cement loading is completed, hatch covers are reinstated using semi-automatic welding with backing strips to ensure full penetration.

All welding is performed:

According to approved WPS
By certified welders (including Class NK approved personnel)
Using proper welding consumables
Under heat control to avoid distortion

The restored section regains structural strength comparable to original hatch construction.

Ultrasonic Testing (UT) – Internal Weld Verification

Following welding completion, ultrasonic testing is performed on welded seams.

UT confirms:

No internal cracks
No lack of fusion
Full penetration weld quality

This inspection step provides assurance to owners, superintendents, and technical managers.

Vacuum Testing – Watertight Performance Verification

Vacuum testing is carried out after welding on upper seams to confirm watertight integrity.

This test helps:

Detect leakage points
Prevent water ingress during heavy weather
Protect cement cargo from contamination
Maintain vessel class compliance

Watertight performance is critical for safe voyage.

Hot Work Permit & Marine Administration Compliance

Hot works at anchorage require official approval from maritime authorities.

Bacviet handles:

Hot work permit letters
Port security formalities
Boarding pass arrangements
Coordination with maritime administration

This ensures legal compliance and smooth operation without delaying vessel departure.

Transportation & Offshore Logistics Support

Cement port operations often occur at anchorage. Our service includes:

Transportation of manpower and equipment
Boat service and offshore supply
Equipment mobilization from Hai Phong
Multi-trip logistics coordination

Strong logistical planning allows execution under tight cargo schedules.

Standby & Overtime Support During Cargo Loading

Cement loading rates vary depending on terminal efficiency. To avoid disruption:

Our team can remain on standby during cargo operations
Overtime execution is available when required
Flexible working hours are arranged to match loading schedule

This ensures repair completion aligns with vessel departure planning.
