Shipspotting 101: Bulk Carriers.

Recent CSL Arrivals make a good lead into Bulker terminology. Firstly a bulker is a Bulk Carrier – they typically carry bulk cargos such as gravel, salt, grain, gypsum, wood pellets etc. They come in 2 Basic Types – Geared and Gearless.
Atlantic Huron is a Geared bulker, She carries her own fixed to ship unloading Gear.
Atlantic Huron is built to Seaway max dimensions, hence its stout appearance. Passing through tight locks also leaves her sides looking rough as seen in a stop from 2012 . Compare her to CSL Tacoma Earlier in the week, which is only built for ocean travel.  (Below)
Both of these bulkers are self unloading. the Holds empty onto a conveyor belt, that travels up and to the end of the boom. this greatly speeds the unloading process though at a cost of capacity. Atlantic Huron at top is unloading to the Halifax grain Elevators, but you can truly See the power of the unloading boom on CSL Metis in Tampa
Malmens (below) is a much smaller bulker, and usually carries gravel. She too is a self unloader with her boom mounted midship, and able to swing out over the pier.

Another type of geared Bulker uses cranes and clamshell buckets for unloading. Universal Amsterdam clearly shows the clamshells on deck between the First and second Crane.

Other Vessels, offer both Options – Such as Barkald, Which has both unloading Cranes and the Self unloading arm. Presumably this offers some flexibility, such as being able to load trucks or rail cars directly with the buckets at unimproved ports.

Finally we have Gearless Bulkers. These vessels rely on shore side handing facilities to offload Cargo. CSL Birchglen is an example of these.

While this post has concerned itself with unloading, We do have 2 posts on Loading. first we have Patron, a Small gearless Bulker loading grain for export. We also had a post on the geared bulker Irma loading wood Pellets.

About Halifax Shipping News

Halifax Shipping News began in 2008 as a blog called The Armchair Captain. The idea behind it came when I would become curious about the comings and goings in the harbour, and research to find their source. I figured if I was wondering, others would be as well, and so I would blog about them. 5+ years later, here we are. This blog is written by Peter Ziobrowski. Peter is a Senior IT System Architect, and holds a BA in the History & Theory of Architecture,as well as diplomas in Computer System Technology and Information System Security. His personal site can be found at http://www.ziobrowski.net. Peter is available for media interviews on local Maritime issues. He also holds a large collection of photos of shipping subjects from Halifax suitable for publication. You can contact him directly via email at peter@halifaxshippingnews.ca.
