Dry Cargoworthy Inspection and Repair Criteria V.2 - 16 Jan 2015 Criteria for use on one way loaded moves of Dry Freight containers This guideline outlines the inspection and repair criteria for dry freight containers. It was intended for one-way trip in a cargo loadable condition. The container must remain safe to move whilst safeguarding the integrity of any general cargo. The container must satisfy the requirements of CSC and TIR. Component

Acceptable Damage Tolerance

ISO DIMENSIONS Main structure All Panels Underside

Dents up to ISO +10mm on side casting face and ISO +5mm on end casting face Dents up to ISO+40mm on all direction of casting faces Dents up to lower casting face

CORNER POSTS J Bar Corner fittings

Up to 25mm or ISO +5mm end face, or ISO +10mm side face Must not interfere with the doors Repair if deformation, cracked or failure

RAILS Front / Rear Top Rails Top Side rails All bottom Rails & Sills Rain Gutter

Dents up to 40mm Dents up to 30mm Dents up to 50mm on web (no limits on flanges). Flange cuts if extending into web, weld only. Must not interfere with the door operations

PANELS Front, Side, Doors Roof, Header Plate. Ventilators & Gaskets Lashing bars or rings

Dents up to 50mm into cube (up to 20mm into cube for Seacell) Dents up to 70mm into the cube from floor to roof, repair only if holed Functioning & watertight or closed off No action for missing or damages lashing bars or rings; replace only if required for trip

DOORS Data plates

Operable, light and watertight. Must be present and properly fitted

UNDERCARRIAGE Crossmembers, Outrigger, Forklift Pockets, Gooseneck, Forklift pocket Straps

Dents up to 75mm on web (no limit on flanges) horizontal cuts in webs to 500mm. Flange cuts if extending into web, weld only Upper flange separation from floor up to 13mm over full length of the cross-member Broken, cracked, cut, torn or missing – Repair

FLOOR / INTERIOR Plywood floor

Repair only if not light and watertight No action on gouge or delamination. Fit overlay patch if floor strength affected. Adjacent height difference maximum allowable 13mm No action if top 3 layers ply loosen or peeled with no additional damage or affect the floor strength.

Floor Fastenings Threshold Plate

Missing, broken / loose up to 3 adjacent fasteners. No protruding fasteners on interior floor. Remove if dent upward more than 10mm or affecting cargo loading

CORROSION

Only using inspection hammer to test on deep seated corrosion; repair holes by welding. Do not cut out corroded material

CLEANLINESS

No infestation, foul odours, hazardous cargo residue, wet, sticky or transferable residue No offensive or possible offensive graffiti / foreign markings

MARKINGS/LABELS (Exterior/Interior)

Must have all ISO decals; renew if missing or not legible. Remove or over-paint all hazardous cargo decals Graffiti / Foreign Markings, remove or over-paint only if offensive or possibly offensive,

Dry Cargoworthy Inspection and Repair Criteria V.2 - 16 Jan 2015 Criteria for use on one way loaded moves of Dry Freight containers In general, apply the outline repair criteria below if beyond the damage acceptable tolerance, and must meet CIC and TIR requirement.

Component

Repair methods

GENERAL

Adopt most economical repair methods within structural strength, safety, light and water-tightness. No repair on any improper repairs, unless they affect the structural integrity. No cosmetic repair or touch-up on interior or exterior of the container. Used materials are allowed but Seaco shall obtain 50% discount or no cost on used material. Cannibalizing parts from Seaco’s “AS IS” sales units but depot must seek Seaco approval. All poor appearance condition must be noted on the repair estimate with photos.

STRAIGHTENING

All dents only straighten by jack to within the acceptable tolerance, it is not necessary to bring it back to original profile. No painting / material costs.

STRAIGHTENING AND WELDING

Cuts, tears or cracks - where possible weld only or straighten sufficiently for welding. Corrosion holes - where possible weld only or apply minimum overlay patch. Do not cut out corroded material. Any dimensions or shape of overlay patches is allowed so long as welding is viable.

TOP RAILS, POSTS AND CASTINGS

Repair to IICL guidelines

SILLS, BOTTOM RAILS, Cuts, tears or cracks to be welded only or straightened sufficiently for welding up to Web. It is not CROSSMEMBER AND necessary to bring it back to original profile as long structural strength is unaffected. UNDER-STRUCTURE No action for cut or torn at flange. Do not cut out corroded material, only apply minimum overlay patch of used material over corroded material. The used material must be rust free with equivalent strength and thickness. Full welding; stitch welding not allowed It should reduce 40% man-hours without cutting out the original material. CROSSMEMBERS

Do not remove damaged cross members unless unsafe. If possible install a new cross member back to back as reinforcement. It should reduce man-hours by 40% without cutting out the original material. If dents within criteria but cracked up to web, only weld crack, no straightening required.

DOORS

Make most economical repair to operational condition

FLOORS

Soft or delaminated floors and holes up to 200mm x 200mm, repair with a 4-5mm steel plate screwed to sound flooring. No limit on steel plate sizes. Repair holes over 200mm x 200mm to IICL repair methods Caulk nail holes if required to ensure light / watertight

VENTILATORS

Functioning & watertight or closed off Only seal cracks

MATERIALS In first instance consider

Corten steel parts will not be required, but replacement parts must give sufficient strength Second hand materials / parts acceptable providing they give sufficient strength

PAINT

If paint is essential, then only one coat required Do not paint under -structure repairs
