Ship Repair at Hon Gai Port, Vietnam — 24/7 Service at Berth and Anchorage

General Introduction to Ship Repair at Hon Gai

Hon Gai Port is part of the Ha Long Bay area and serves bulk cargoes such as coal, clinker, and cement. Vessels call at Hon Gai berth,Cai Lan Terminal, and Hon Gai/Bai Chay anchorage. Weather can change fast, rain can be heavy, and visibility can drop. Coal dust, salt, and humidity speed up wear on electrical parts, hatch covers, cranes, sea-water piping, and coatings.

Vietnam Shiprepair Co. works as a mobile shipyard here. We board fast, plan with your Master and Chief Engineer, and complete work safely and on time. Our welders are IACS Class-approved (WPS/WPQ). Our procedures align with ABS, LR, DNV, ClassNK, BV, RINA, and VR. We provide NDT (UT/MPI/DPT), electrical tests (IR/PI/surge), hydro tests, ultrasonic hatch tests, and load tests with a signed report pack for Class/Flag/Terminal.

Where We Work in the Hon Gai Area

• Berths: Hon Gai and Cai Lan terminals.

• Anchorages: Hon Gai/Bai Chay and nearby waiting areas.

• Coordination: We handle boat hire, gate access, hot-work permits, and site rules with your agent/terminal.

How We Attend

1. Inquiry — You send an RFQ with photos/log notes.

2. Boarding ETA — We confirm when we can get on board (berth or anchorage).

3. On-board check — We inspect, measure, agree a safe work area around cargo.

4. Two choices — Option A (recover now, keep schedule) or Option B (full overhaul when time/parts allow).

5. Execution — Disassembly → parts ready → reassembly → test, with short updates at each step.

6. Handover — Trials + test sheets + photos + certificates. Warranty by scope.

Services for Hon Gai — Port and Anchorage

A) Electrical Power, Generators, and Motor Rewinding (our key strength)

Why it matters here: Coal dust + salt + rain = low insulation, hot spots, and random trips during loading.

Motor rewinding (quấn lại động cơ):
We rewind motors for cargo cranes, mooring winches, windlass (anchor winch), hatch drives, and pump/fan sets.

• Open and check the core and nameplate.

• Remove burnt/aged windings.

• Rewind with the right wire class and slot insulation.

• Varnish impregnation + oven bake to restore strength and insulation.

• New bearings, polish shaft, align coupling.

• Tests: IR (insulation resistance), PI (polarization index), surge test (inter-turn), and no-load run.

Result: Cooler running, correct torque, and a clear test sheet for your files.

Generators/alternators & AVR tuning:
Clean stator/rotor (dust-safe), verify insulation class, renew bearings, balance rotor when needed, service slip rings/brushes, then tune AVR so voltage is stable and parallel load sharing is smooth (no “hunting”). We perform no-load and load trials where safe.

Switchboards/MCCs:
Dust-safe cleaning, busbar de-oxidation, terminal torque check, replace tired contactors/relays, improve ventilation. Renew and label cables; update as-built drawings.

Emergency power:
Fix auto-start on the EG set, check charger/rectifier, battery load test, verify ATS logic.

B) Deck, Hatch Covers, and Cargo Handling

• Steel renewal: deck plates, hatch coamings (the hatch frame), bulwarks, catwalks.

• Hatch covers: new rubber packing, set cleats/wedges, clean drains; ultrasonic tightness test to prove weather-tightness.

• Cranes and grabs: brake relining, seal kits, bearings; wire rope checks; static/dynamic load tests with calibrated water bags.

• Ventilation and air pipes: unblock dust, fit new screens, reduce noise/pressure drop.

We schedule deck work around loading so we do not block cargo.

C) Engine Room and Mechanical

• Main/aux engines: cylinder head overhaul; injector and fuel pump service; valve/tappet set; bearing checks; liner/piston inspection; alignment.

• Turbochargers: clean, check clearances, balance if needed.

• Boiler/economizer: remove scale, patch leaks, renew tubes, set safety valves.

• Pumps/compressors: ballast, bilge, sea water, fuel, lube pumps; seals, bearings, clearances; compressor valve kits.

• Automation: sensors/actuators; governor tuning; find root cause of trips/slowdowns.

• HVAC/provision plant: find leaks, set expansion valve, service fans/belts, clean heat exchangers.

If time is short, we recover first and book the full overhaul later.

D) Piping and Pressure Tests (SW/FO/LO/Ballast/GS)

• Sea-water lines: replace pitted spools with the right wall thickness and grade; improve supports where vibration is seen.

• Hydro tests (renewed sections): normally 1.5× design pressure, hold ≥ 30 minutes, no leaks and no pressure drop beyond gauge accuracy.

• Valves: seat/back-seat tests per API 598; non-return function confirmed.

• Fuel/lube lines: flushing to maker’s cleanliness; strainer ΔP within limits.

• Ballast: air pipe heads and alarms checked; hydro results recorded.

We write test pressure, duration, instruments, and results in the report.

E) Underwater and In-Water Work

• UWILD (underwater inspection instead of drydock): photo/video of sea chests, overboard, bilge keels, rudder stock, anodes, CPP hubs (if fitted), and coating.

• Hull cleaning and propeller polishing: reduces fuel burn and improves speed.

• Temporary plugs: isolate sea chests/overboard to replace valves.

• Rope/net removal from propeller/shaft.

• Thickness checks under water to plan your next drydock.

We always check sea state/visibility first. If unsafe, we give a top-side temporary fix and return later.

F) Bridge, Navigation, and Radio

• Radar, ECDIS, echo sounder, AIS, VDR: repair, calibration, sensors and antennas.

• Gyro and magnetic compass: adjust/compensate; issue certificate if required.

• GMDSS/VHF: DSC tests; power supply checks; feeder/antenna renewal.

• Alarms/monitoring: ER alarm panel, tank level sensors, and switches.

FAQs (short answers for quick reading)

Can you attend both berth and anchorage at Hon Gai?
Yes. We do both. We coordinate access and boat hire with the agent/terminal.

How fast can you rewind a motor?
It depends on the size and condition. We often give a safe temporary run first so you can keep cargo moving, then complete the full rewind with tests.

Do you issue certificates for load tests and hatch ultrasonic tests?
Yes. We provide proper reports and certificates for Class/Flag/Terminal.

Can you dive if the sea is rough?
We check sea state and visibility. If unsafe, we provide a top-side temporary solution and return later.

Do you help with spares and customs?
Yes. We receive, document, and deliver spares to the vessel. If OEM parts are delayed, we suggest approved equivalents or a staged plan.
