Sawn Timber Shipping
Sawn Timber Ships are unobstructed, box-type, square holds, with large hatch openings, being usually equipped with their own cargo-handling derricks or cranes. Thus, loading or discharging is speedily effected, and the ships’ configurations enable them to carry containers in addition or as an alternative to packaged lumber. Carriage may also be effected by laden lorries on Ro/Ro Carriers – trailer carriers where port and infrastructure facilities and circumstances permit.
Typical Timber Carriers and Ro/Ro Ships are purposefully build to carry this refrangible cargo. Length packaged lumber, sometimes known as flush-bundled, may be sawn into individual pieces of timber each of a particular length, stacked together in such a way as to provide a packaged unit of 32 pieces measuring approximately 50 cm (20″) by 60 cm (24″), secured by wire straps to keep it in one unit, and with flush ends butted neatly together.
Such units may be shipped four together, giving overall measurements of 100 cm (40″) by 120 cm (48″) with, of course, flush ends, and complete with wire straps and loops to ease cargo handling.
Truck packaged lumber is similar to length packaged in all respects, except that the lengths of each individual piece of timber vary, and so only one end of each bundle is flush, the other comprising variable lengths.
The development of the timber market into length and truck packaged lumber has had a profound effect on the type of ship employed in the carriage of this commodity.
Much of the sawn timber transported at sea comprises softwoods, and these are used for the major purposes of building (both for joinery and construction) and for packaging. The highest quality of softwood is used for joinery and lower grades for packaging.
Care must be taken during carriage to avoid mold and fungus which may cause discoloration and eventual rotting of the wood. Not many years ago, sawn timber was predominantly carried in individual odd lengths of wood, which naturally took a considerable time to load and to stow and equally long to discharge. Onward transportation (eg: by lorry) was similarly beset with delay.
A breakthrough in timber handling was made, however, with the introduction of moving timber in a pre-packaged condition, standard sizes of packages becoming the norm. At the same lime many of the older measurements – referring as they do to loose cargo – have been largely forsaken for present-day carriage of sawn timber, which today is mainly transported as either length packaged timber or truck packaged timber. Length packaged lumber, sometimes known as flush-bundled, may be sawn into individual pieces of timber each of a particular length, stacked together in such a way as to provide a packaged unit of 32 pieces measuring approximately 50 cm (20″) by 60 cm (24″), secured by wire straps to keep it in one unit, and with flush ends butted neatly together.
Such units may be shipped four together, giving overall measurements of 100 cm (40″) by 120 cn (48″) with, of course, flush ends, and complete with wire straps and loops to ease cargo handling.
Truck packaged lumber is similar to length packaged in all respects, except that the lengths of each individual piece of timber vary, and so only one end of each bundle is flush, the other comprising variable lengths. The development of the timber market into length and truck packaged lumber has had a profound effect on the type of ship employed in the carriage of this commodity.
Seaborne carriage of timber and forest products encompasses hardwood and softwood logs; sawn lumber; wooden products (such as railway sleepers); by-products (such as plywood); pulpwood, wood-pulp and wood-chips; and paper products, each in its way demanding specialized handling in sophisticated ships.
Most timber cargoes are limited to volume, however, in that ships’ cargo compartments will be filled before deadweight capacity is attained.
Consequently, where practicable, timber is carried on deck as well as in holds, ships being specially built with this feature in mind. Legislation on such deck-carried cargo is extremely strict, though, and is clearly laid-out in IMO’s (International Maritime Organization’s) Deck Cargo Regulations as framed by the International Conference on Load-Lines, 1966, on which certain national laws have been based.
General considerations when carrying timber on deck encompass stability of the ship; security of the cargo, in other words avoidance of its shifting at sea; excess weight on deck and/or hatch-covers; safe movement of crew around the ship; and visibility from the navigation bridge.
Ships built for such a trade should moreover be fully equipped with padeyes; chains; wires; pearlinks; turnbuckles and stanchions. These stanchions may be permanent; collapsible steel stanchions; or wooden stanchions; which are the Owners responsibility to provide.
The deck stow should not exceed a height above the deck equivalent to one third of the ship’s overall beam, and the heights of stanchions and crane pedestals may affect the quantity of cargo a ship can carry in this way.
The secure and proper stowage of deck timber has the effect of increasing a ship’s freeboard and, because of this, timber carriers may be measured and allotted lumber load-lines in addition to the usual load-lines, these being painted in at midships and permitting somewhat deeper loading.

These trees grow relatively quickly, making softwoods more abundant and less expensive than hardwoods. Softwoods are generally lighter and less dense than hardwoods. Some common softwood species include:
a. Pine: Pine is a popular softwood, known for its straight grain and light color. It is easy to work with and widely used for construction, furniture making, and wood carving.
b. Spruce: Spruce is a light-colored wood with a straight grain and uniform texture. It is commonly used for construction, particularly for framing, as well as for making musical instruments like guitars and violins.
c. Fir: Fir is another softwood with a straight grain and light color. It is used in construction for framing, plywood, and paneling due to its strength and stability.
d. Cedar: Cedar is a durable and aromatic wood that is resistant to decay and insects. It is commonly used for outdoor applications, such as decking, fencing, and siding, as well as for making furniture and cabinetry.
- Hardwood: Hardwoods come from deciduous trees, which lose their leaves annually. These trees grow more slowly than softwoods, making hardwoods denser and more expensive. Hardwoods are typically more durable and have a more diverse range of colors and grain patterns than softwoods. Some common hardwood species include:
a. Oak: Oak is a strong and heavy hardwood with a distinct grain pattern. It is widely used for furniture, flooring, cabinetry, and construction due to its durability and attractive appearance.
b. Maple: Maple is a light-colored hardwood with a fine, uniform grain. It is commonly used for furniture, flooring, cabinetry, and musical instruments due to its strength and stability.
c. Walnut: Walnut is a dark-colored hardwood with a rich, distinctive grain. It is highly prized for its appearance and is used for high-quality furniture, cabinetry, and decorative woodwork.
d. Cherry: Cherry is a hardwood with a reddish-brown color that darkens with age. It has a fine, straight grain and is used for furniture, cabinetry, and interior trim.
e. Mahogany: Mahogany is a tropical hardwood known for its reddish-brown color, straight grain, and excellent workability. It is often used for high-end furniture, cabinetry, and boat building.
f. Teak: Teak is a tropical hardwood with a golden-brown color and straight grain. It is highly valued for its natural resistance to moisture, insects, and decay, making it ideal for outdoor furniture, decking, and boat building.
These are just a few examples of the many timber types available. Each type of wood has its unique characteristics, making it suitable for specific applications and aesthetic preferences. When choosing a timber type for a project, consider factors like strength, durability, workability, and appearance.
