![]() ![]() This includes oil and drill rigs, oil processing plants, floating factories, equipment used for dredging purposes, offshore structures, floating drydocks, and other ships that can fit on board. This type of ships is common for a few specific types of cargo. The “Red Box Audax” semi-submersible vessel With the cargo now resting on the deck, the vessel is able to safely move this load. Once they are correctly positioned, the ballast water is pumped out until the deck of the vessel rises above the water. The principle behind such ships is that floating cargo and goods can be loaded onto the submerged deck by floating them directly over the resting area. This lowers the ship deeper into the water until the upper deck is submerged a few metres below the water’s surface. These are classes of ships that are able to use ballast water to increase their draft. These different classes of vessels use widely contrasting techniques in lifting their large loads. Types of Heavy Lift Vesselsīroadly categorizing heavy lifting vessels (HLVs), they are of four main classes – In this article, we will delve into the world of heavy lifting vessels and cranes, and the science behind their enormous lifting prowess. They perform these difficult tasks by using innovative techniques in engineering and ship design. What makes them different from conventional heavy-duty carriers is their ability to handle loads that would otherwise have compromised the structural integrity of a ship. These gigantic vessels can lift and ship just about any load in the world, from massive carriers to large semi-submersible oil rigs. And this is where Heavy Lifting Vessels (HLVs) comes into place. Moving such cargo could be for a variety of reasons- from shipping heavy, dense goods that cannot be borne on normal carriers, to transporting other ships across the world. They move trillions of dollars’ worth of goods across the entire globe.īut what happens when you want to shift cargo that is considerably heavy, sometimes too heavy for even conventional ships? Ships are massive structures capable of carrying enormous loads. ![]()
