A bulk carrier or bulker is a merchant ship specially designed to transport unpackaged bulk cargo—such as grain, coal, ore, steel coils, and cement—in its cargo holds. Since the first specialized bulk carrier was built in 1852, economic forces have led to increased size and sophistication of these ships.
Umiak I is a purpose-built ice-strengthened bulk carrier constructed for the Voisey's Bay Nickel Company, [4] a wholly owned subsidiary of Vale, to transport ore from the Voisey's Bay Mine. According to an article in the April 2006 issue of The Gossan an internal publication of the Voisey's Bay Nickel Company, Umiak I had completed her sea ...
This is a list of bulk carriers, both those in service and those which have ceased to operate. Bulk carriers are a type of cargo ship that transports unpackaged bulk cargo . For ships that have sailed under multiple names, their most recent name is used and former names are listed in the Notes section.
Handymax Bulk Carrier "Orientor 2" Handymax and Supramax are naval architecture terms for the larger bulk carriers in the Handysize class. Handysize class consists of Supramax (50,000 to 60,000 DWT), Handymax (40,000 to 50,000 DWT), and Handy (<40,000 DWT). The ships are used for less voluminous cargoes, and different cargoes can be carried in ...
The ships are bulk carriers, 189.99m long overall [3] (182m between perpendiculars) with 56,000 dwt and approximately 31000gt. Hold volume is over 70,000m³, divided between five cargo holds with four cranes. [4] Main engines are generally MAN B&W 6S50MC-C low-speed diesels. Service speed is 14.5 knots. [5]
Modern lakers are usually designed and constructed for a 45-50 year old service life, outlasting ocean-going bulk carriers. [43] As of 2023, ocean-going bulk freighters average an 11-year lifespan, due in part to the corrosive effects of saltwater. [44] [45] Some of the lakers have been known to have long careers.
Compared to larger bulk carriers, handysizes carry a wider variety of cargo types. These include steel products, grain, metal ores, phosphate, cement, logs, woodchips and other types of so-called 'break bulk cargo'. They are numerically the most common size of bulk carrier, with nearly 2000 units in service totalling about 43 million tons.
Standardising on this design makes the vessels interchangeable, and offers operational flexibility. [1] Gearbulk also operates open hatch jib craned (Fleximax) vessels and several bulk carriers for general bulk cargoes. [1] On 2 January 2015, the MS Bulk Jupiter sank off the coast of Vũng Tàu, Vietnam. [5]
