SVC Marine Services provides jib crane repair, grab crane repair, deck crane structural repair, hoisting wire supply, luffing wire supply, welding, NDT support, class inspection support and onboard load test services for vessels calling Vietnamese ports, anchorages and shipyards.
This project page records a Jib Crane No.4 repair job in Hai Phong, Vietnam. The crane was damaged during cargo discharging operation. SVC Marine technicians attended onboard to survey the damaged jib crane, assess the repair scope and prepare the repair plan for crop and renew, welding, inspection and load testing.
SVC Marine performs practical crane repair works with our marine repair team, welders, fabricators, rigging support, technical attendants and surveyor support where required. For jib crane damage, the repair must be controlled carefully because the structure is directly related to lifting safety, cargo operation, class acceptance and vessel readiness.
Jib Crane Repair in Hai Phong, Vietnam
Jib cranes, provision cranes, grab cranes and deck cranes are critical lifting appliances onboard commercial vessels. When the jib body, reinforcement bracket, hoisting wire, luffing wire, sheave, hook block or crane structure is damaged, the vessel may face cargo delay, unsafe lifting condition, class restriction or port operation risk.
SVC Marine provides crane repair services for vessels in Vietnam, including structural repair, welding repair, wire supply, component replacement, NDT inspection and load test support after completion.
Project Scope: Jib Crane No.4 Damage During Cargo Discharge
During this project in Hai Phong, Jib Crane No.4 was damaged during discharging operation. After onboard survey, the repair scope was prepared based on the damaged area, class requirement and safe return-to-service condition.
The original repair workflow included:
- Onboard survey of damaged jib crane structure
- Repair planning based on damaged area and sketch
- Crop and renew or fair-up of damaged crane structure
- Renewal of reinforcement brackets for jib body
- Use of high tensile steel AH36, thickness 10 mm
- Fit-up inspection by class surveyor before welding
- Welding repair and inspection at shipyard
- UT and PT after welding completion where required
- Transfer back onboard and assembly
- Final accuracy confirmation by class surveyor
- Onboard load test after installation
Typical Jib Crane Repair Scope
The actual repair scope depends on crane type, SWL, damage condition, steel thickness, access, vessel schedule, class requirement and spare part availability. A typical jib crane repair job may include:
- Visual inspection of damaged jib crane structure
- Checking jib body, brackets, pins, sheaves and wire condition
- Marking damaged steel sections for crop and renewal
- Removing damaged plate, brackets or stiffeners
- Fabricating replacement steel parts
- Fitting new AH36 or approved steel material
- Welding by marine repair welders
- Grinding and finishing after welding
- UT, PT or other NDT where required
- Checking hoisting wire, luffing wire, sheaves and hook block
- Class, surveyor or owner’s representative inspection
- Function test and load test after repair
Grab Crane, Hoisting Wire and Luffing Wire Support
In addition to jib crane structural repair, SVC Marine can support grab crane repair, crane wire supply and selected crane component replacement in Vietnam.
Our crane-related support may include:
- Grab crane repair
- Deck crane structural repair
- Provision crane repair
- Engine room crane repair
- Hoisting wire supply
- Luffing wire supply
- Wire rope replacement support
- Sheave, hook block and bearing checking
- Hydraulic or mechanical troubleshooting support
- Load test arrangement after repair
Crane Structural Repair and AH36 Steel Renewal
Crane structural repair must be treated as a lifting safety job, not only normal steel repair. If the jib body, reinforcement brackets or load-bearing members are damaged, repair material, welding method, fit-up, NDT and class inspection must be controlled properly.
In this project, the repair used high tensile steel AH36 with 10 mm thickness for the renewed section. Fit-up inspection was confirmed before welding, and NDT was applied after welding according to the repair requirement.
NDT and Class Inspection
For crane repair, class or surveyor attendance may be required before the crane is returned to operation. Inspection may include fit-up checking, welding inspection, UT, PT, visual inspection, dimensional checking and final load test confirmation.
SVC Marine can prepare the repair area, support surveyor attendance, provide photo records and follow the required testing steps after welding. The crane should not be returned to lifting operation until the repair and test are accepted according to the vessel’s requirement.
Onboard Load Test After Crane Repair
After crane structural repair, wire replacement or major component repair, an onboard load test may be required. The test helps confirm the crane’s lifting function, brake holding condition, hoisting, luffing, slewing and structural response under controlled load.
SVC Marine can support crane load test preparation, water bag or test weight requirement, safety area control, technician attendance, photo record and completion reporting for the owner or manager.

Common Reasons for Crane Repair Attendance
Shipowners and managers may request jib crane or grab crane repair after:
- Crane damage during cargo discharging
- Jib body deformation or crack
- Broken reinforcement brackets
- Hoisting wire damage
- Luffing wire damage
- Abnormal crane noise or vibration
- Crane overload incident
- Grab crane malfunction
- Class or port state control comment
- Failed crane load test
- Pre-drydock or post-repair crane inspection requirement
Safety Notes for Jib Crane Repair
Jib crane repair involves heavy lifting, working at height, hot work, structural load-bearing members, wire tension, suspended components and possible class requirement. Before work starts, the vessel and repair team should confirm safe access, isolation, lifting plan, staging, fire watch, hot work permission and safe support for crane components.
No damaged crane should be used for lifting until the repair condition, inspection result and load test requirement are properly checked. Unsafe temporary use can create serious risk to crew, stevedores, cargo, vessel structure and port operation.
