The term seaworthy packaging procedure is intended to indicate that the packaging must additionally strengthen and withstand the conditions of maritime transport and then resist to more severe stresses.

But you may note the most severe stresses do not occur during maritime transport itself, but instead during cargo handling (due to impact, pushing, overturning etc.).

In below you can see a draft of seaworthy packing procedure which can be used for industrial goods:

1- Seaworthy Packing Procedure - Vendor’s Obligations and Responsibilities:

VENDOR shall be solely responsible for packing and marking of CARGO with respect to handling, transport, and storage at plant site. VENDOR shall be fully liable for proper, sufficient and adequate packing, completeness of contents, protection of contents for a storage time of 6 months, and correct preparation of the packing list. All damage and costs whatsoever resulting from inadequate or insufficient packing shall be fully charged to VENDOR.

Packing and conservation of goods shall be sufficient to protect them from damage during transit from point of manufacturer and storage at job SITE under conditions which may involve multiple handling, extended storage, exposure to moisture and the possibility of pilferage. The content must withstand 1 year transit conditions without suffering damage and VENDOR shall give recommendations for further two-year storage under SITE conditions. Required storage facilities and procedures shall be advised by VENDOR in advance.

2- Seaworthy Packing Procedure - General Requirement Rules for Packing

Case and crated shall be made from new, sound and seasoned lumber. Thickness of sheathing (or outer plate) shall be in accordance with the chart below.

If so required for static reasons, thicker sheathing shall be used, in accordance with size and weight of the package. Timber crates and boxes shall be strong enough to withstand without any damage, transport and numerous handling between the works and the SITE.

Cases and crates with gross weight up to 1,000 kgs shall be provided with bottom cleats of min. 40 mm thicknesses to ensure clearance for handling by forklift. Cases and crates exceeding gross weight of 1,000 kgs shall be provided with skid runners, number and size according to weight of package.

The contents of cases shall be protected by waterproof and strong plastic foil, which shall be sealed by welding.

An adequate quantity of moisture absorbent (silica gel) shall be added to protect the contents for sufficiently long time from corrosion.

These specifications will be applied for 1) machinery such as pumps and compressors and 2) Instrument and electrical components, which contains electronic part. As for 1) piping materials such as pipes, valves and fittings, 2) construction materials and 3) structural steel and steel plates for tanks, the above specifications will not be applied.

Felt, cellophane paper, polyester cuttings, crepe cellulose and some equally efficient materials may be used for padding or cushioning. Wood shavings and other paper shall not be used for padding or cushioning.

Materials shall be protected against corrosion during transit as necessary. All bright and machined parts shall be coated with a recognized rust preventative suited to the particular application concerned. All internal parts of machinery shall be treated with lubricant containing rust and oxidation inhibitors to protect equipment from any possible damage. Such lubricants shall be compatible with those which will subsequently be used in service and shall be identified by appropriate tagging.

When required, materials shall be painted or coated din accordance with the particulars contained in the purchase order and /or specifications.

Packages containing “FRAGILE” articles shall be appropriately packed and in addition to the words “Fragile-Handle With Care” being stenciled on two opposite sides, internationally recognized symbols shall also be used “This Side Up” Spare part for two years operation, which shall be individually tagged, must be covered with a suitable preservative and wrapped with greaseproof paper and be packed in separate cases from the prime item. The cases are to bear the markings as specified and in addition the words “SPARE PARTS FOR TWO-YEARS OPERATION.”

Commissioning spares shall be individually tagged and marked “COMMISSIONIN SPARES” and shall be packed and shipped with the prime item.

Should any materials be scheduled to be freighted as deck cargo, additional packing instructions may be required of which VENDOR will be advised for vessels and column. shipment cradles will be used throughout the transportation. Cradles to be secured to vessels and columns by strapping.

Unless otherwise specified, all cases, boxes, bundles and containers are to be securely metal strapped with a minimum of two un-annealed steel straps in each of two right angled and opposite directions, or where applicable wood re-enforces.

Cases and crates shall, according to their weight and size, be provided with two or more steel straps made of unannealed steel, applied with a stretching tool and secured with crimped steel seals.

Units or parts belonging to main equipment but separately packed shall be clearly marked for easy identification with main equipment to which they related.
