How much can a bulk carrier hold?
Ultramax bulk carriers are medium-sized vessels. Larger than Supramax vessels, they have a carrying capacity generally between 60,000 to 65,000 DWT. These vessels are considered an upgrade over the smaller Supramax carriers. Panamax vessels are medium-sized vessels with a carrying capacity of 65,000 and 80,000 DWT.
What are the hazards in handling bulk cargoes?
Carrying solid bulk cargoes involves serious risks, which must be managed carefully to safeguard the crew and the ship. These risks include reduced ship stability, and even capsizing, due to cargo liquefaction; fire or explosion due to chemical hazards; and damage to ship structures due to poor loading procedures.
How big is a cargo hold?
Depending on the size of the container ship, most cargo vessels hold anywhere between 10,000 TEU to 21,000 TEUs. Since containers are measured in TEUs, the TEU capacity indicates exactly how many containers can be placed on the deck and below the deck of the ship.
What are the three types of bulk cargo?
Bulk carriers are segregated into six major size categories: small, handysize, handymax, panamax, capesize, and very large. Very large bulk and ore carriers fall into the capesize category but are often considered separately.
What is the biggest bulk carrier in the world?
Valemax
Valemax is the largest bulk carrier class in terms of DWT. Valemax-class ships have a capacity ranging from 380,000 to 400,000 tons deadweight. They are also amongst the longest ships of any type currently in service.
What are used in self unloading bulk freighters?
A self-discharger (or self-unloader) is a ship that is able to discharge its cargo using its own gear. The most common discharge method for bulk cargo is to use an excavator that is fitted on a traverse running over the vessel’s entire hatch, and that is able to move sideways as well.
What are the 9 common hazards of bulk cargo on ships?
9 Common Hazards Of Bulk Cargo On Ships
