Before containerisation, apart from bulk, most cargoes were handled as general cargoes. Even vehicles were handled as general cargo before the advent of vehicle carriers and ro-ro vessels. Most ships had their own handling facilities in the form of derricks. Now the majority of cargo is shipped in containers, negating the need for ships to have their own cargo handling gear, relying entirely on shore facilities.
Much of the general cargo carried now is of a type that cannot be readily packed into containers. General cargo is loaded from the dock by traditional dockside cranes except where the weight precludes this. To speed up loading, much of the cargo is unitised.
The process of unitising consists of strapping together individual items of cargo to form a single unit. Ships designed to carry heavy cargoes usually have their own cargo handling gear in the form of heavy duty derricks or cranes. Many ships now have cranes instead of derricks. With the boom in the boating leisure market, some companies now specialise in the transportation of luxury pleasure craft. The craft are either lifted off the dock or can be directly lifted from the water. The boats are lifted using a spreader frame with cargo straps.
Bulk cargo or general cargo are goods that must be loaded individually, and not in intermodal containers nor in bulk as with oil or grain. Ships that carry this sort of cargo are called general cargo ships. The term break bulk derives from the phrase breaking bulk—the extraction of a portion of the cargo of a ship or the beginning of the unloading process from the ship’s holds. These goods may not be in shipping containers. Break bulk cargo is transported in bags, boxes, crates, drums, or barrels.
Bulk cargo (bulk dry cargo)
Bulk cargo is commodity cargo that is transported unpackaged in large quantities. It refers to material in either liquid or granular, particulate form, as a mass of relatively small solids, such as petroleum/crude oil, grain, coal, or gravel. This cargo is usually dropped or poured, with a spout or shovel bucket, into a bulk carrier ship’s hold, railroad car/railway wagon, or tanker truck/trailer/semi-trailer body.
Smaller quantities (still considered “bulk”) can be boxed (or drummed) and palletised. Bulk cargo is classified as liquid or dry.
RoRo allows your products to roll on and off the vessel, as opposed to being lifted onboard using cranes. Self-propelled products, such as cars and tractors, roll on and off the vessel on their own wheels. Products that are not self-propelled are placed on handling equipment with wheels in the terminal to be rolled on and off the vessel. Your product thus remains on the handling equipment for the entire sea voyage.
Loading and discharge are via a wide stern ramp. The ramp capacity ofmost other RoRo carriers have ramp capacities of around 150 tonnes. Shipping your products the RoRo way is a secure and efficient process as less lifting is required and loading is not weather-dependent.
