Lashing bar LB-2S, Lashing bar LB-3S, Lashing bar LB-3V-1

Common issues

• Corrosion and pitting on the bar body and threaded ends from saltwater exposure
• Bent or permanently deformed bars from cargo shifting or overload in heavy weather
• Thread damage or seizure on turnbuckle/tensioning end fittings
• Worn or elongated hook/eye end fittings reducing secure engagement with lashing points
• Cracked welds at fixed end fittings
• Illegible or missing type-approval marking, complicating traceability

Inspection checklist

• Visual check for bends, kinks or permanent deformation along the full bar length
• Check threaded ends and turnbuckle barrels for corrosion, thread wear and free rotation
• Inspect hook/eye end fittings for crack initiation, wear and correct engagement geometry
• Verify the type-approval marking/tag is legible and matches the certified lashing bar type
• Check for corrosion/pitting depth, especially at weld heat-affected zones
• Confirm bar size and length match the vessel's approved Cargo Securing Manual for the stowage position
• Function-test turnbuckle tensioning before use
• Segregate and tag any bar failing visual inspection for withdrawal from service

Service intervals

Typical wear limits

Ranges are typical for this design class. Always confirm against the manufacturer documentation for your serial number.

Critical spares

• Turnbuckle/tensioning body matching the certified bar type (LB-2S/LB-3S/LB-3V-1)
• Replacement lashing bars of the same DNV type-approved type and length
• Securing/cotter pins for turnbuckle and hook ends
• Corrosion-protective coating or grease for threaded sections

Safety

• Sudden bar or fitting failure under load can cause serious injury from whipping or recoil
• Working with a bent, corroded or cracked bar risks cargo shift and crew injury during lashing/unlashing
• Never substitute a lashing bar type or length not listed for the stowage position in the vessel's approved Cargo Securing Manual
• Overtightening beyond rated working load can mask hidden thread or weld damage until sudden failure

Class survey

Cargo securing equipment is checked against the vessel's approved Cargo Securing Manual during periodic surveys; class expects the DNV type-approval certificate (TAS0000288) on file, bars of the certified type/length used in each stowage position, and damaged or corroded bars withdrawn rather than substituted with uncertified equipment.
