Ship Model, Victory Ship Type VC2-S-AP

Description

By 1943, the outlook for an Allied victory in World War II was steadily improving. The reign of the U-boats that had plagued Allied convoys in the Battle of the Atlantic was coming to an end. And the Axis powers were finally losing the tonnage war, which aimed to sink Allied merchant ships faster than replacements could be built. While the mass-produced Liberty ships were faithfully carrying cargo and troops to war zones, these ships were relatively slow. In response, the War Shipping Administration commissioned a new class of emergency vessels called Victory ships. This model represents one of the 534 Victory ships that were built alongside the Liberty ships in seven shipyards around the country.

Speed was the key difference between the Victory and Liberty ships. When Liberty ships were designed, all of the new steam turbine engines were reserved for naval vessels, leaving the Liberty ships with reciprocating steam engines. While these engines were reliable, the ships could only reach 11 knots, leaving them vulnerable to attack. As the war progressed, more turbine engines became available and were installed in the Victory ships, giving them a speed of over 16 knots.

Another improvement of the Victory design was a stronger and larger hull. This meant that more cargo could be transported at once, and improved the odds of the vessels continuing to serve in the merchant fleet during times of peace. After World War II, 170 Victory ships were sold as commercial freighters. About 20 were loaned back to the military and used in the Korean and Vietnam Wars. Several Victory ships have been preserved as museum ships and are currently located in California and Florida.

Model, LNG Carrier Methane Shirley Elisabeth

Description

Liquid natural gas (LNG) is composed mostly of methane (80–99%). For shipping, it is chilled to -260°F, at which point it is condensed into a liquid 1/600 of its original volume. It is transported globally in this form aboard ships with insulated containers that offload it at special terminals.

LNG tankers have been around the United States since 1959, when the first cargo was exported from Lake Charles, Louisiana, to England. There are around 200 LNG tankers in service in 2007, and nearly that many more are on order at specialized shipyards to meet the globe’s growing demand for this source of energy.

LNG tankers have completed more than 40,000 voyages without serious incident; they have the best safety record of any category of commercial shipping. However, they are among the world’s most expensive and difficult ships to build.

Methane Shirley Elisabeth is one of the newest types of LNG tankers, having been delivered to its owners in March 2007. Its double hulls, separated by six feet of seawater, protect the four gas tanks, which are refrigerated and insulated to maintain the -260°F temperature. The tanks, or membranes, consist of layers of stainless steel and other materials alternating with thick foam insulation. The insides of the membranes are lined with stainless steel, corrugated in two dimensions to prevent the frozen gas from sloshing around inside.

Ship Model, Catcher-Processor Alaska Ocean

Description

This scale model of the fishing vessel Alaska Ocean was custom-built for the Smithsonian by Erik A. R. Ronnberg Jr., at his shop in Rockport, Massachusetts. The starboard hull is cut away to reveal the factory where workers process tons of fish into blocks of frozen fillets, minced fish, and surimi (used in making imitation crab meat and other food products). The cutaway also shows the laboratory where fish products are tested, the freezer hold, a stateroom, and the galley. On the weather (top) deck, the model features all of the deck machinery, the trawling equipment, and the vessel’s rigging. A net full of fish is shown being emptied into one of the bins on the factory floor below.

Ronnberg spent about 27 months building the model, and estimates he spent 5,500 hours getting every detail right. While he built the wooden hull according to design drawings provided by naval architect Guido Perla of Seattle, he had to make his own drawings and patterns to craft the machinery and equipment, most of which are cast in metal. Ronnberg used cheesecloth and tulle to make the net and spent untold hours fashioning the chafing gear out of acrylic yarn, which he knotted in bunches before separating the strands by hand.

He studied photographs and films of the actual vessel at sea, and made detailed figures of people dressed in appropriate working gear in the factory, on the deck, in the fish hold, in the galley, and on the bridge. The model is populated with 125 figures, 1,200 individual fish, and several masses of fish in the cod end of the net. Everything on the model is painted by hand. The scale is 3/16^th inch = 1 foot.

The Alaska Ocean itself is a 376-foot-long vessel in the Seattle-based catcher-processor fleet. Workers catch, process, package, and freeze groundfish—mostly pollock and Pacific whiting—in the Bering Sea and in the waters off the coast of the Pacific Northwest. The vessel can harvest about 325 metric tons of fish per day and can freeze over 250,000 pounds of fish product daily.

The idea to build the Alaska Ocean began in the late 1980s. Jeff Hendricks, a fisherman from Anacortes, Washington, who owned and operated a fleet of boats in partnership with a Japanese company, decided to “Americanize” his operations. This was in advance of the American Fisheries Act of 1998, which sought to increase American ownership in the fleet by requiring that vessels be American-built, owned, and operated. Although Hendricks sought bids from several American shipyards for his new venture, there were none at the time that could handle the scope of the vessel he envisioned. Eventually, he worked with a shipbuilder in Norway to expand and rebuild an American oil supply vessel. The Alaska Ocean arrived in Anacortes in the summer of 1990 and began fishing that fall with a largely local crew. It remains in the fleet and, as of 2008, is owned and operated by Glacier Fish Company.

Because catcher-processors are so efficient, their operations are highly regulated to prevent overfishing. A harvest quota is determined by the National Marine Fisheries Service and members of the Pollock Conservation Cooperative, a group of catcher-processors including the Alaska Ocean, divide up the quota amongst themselves. This self-regulating measure ends what is often called the "race for fish," and results in more careful, less wasteful fishing.

Independent scientific observers also travel aboard every vessel in the fleet, monitoring the trawling and empyting operations. They record all by-catch, the term for fish caught in the net other than the target species. There are hard limits on allowable by-catch for certain species, and because the data are computed, reported, and shared for the fleet as a whole, individual vessels are motivated to monitor the by-catch and make adjustments.

Ship Model, ms Zuiderdam

Description

This waterline model represents the ms Zuiderdam, a cruise ship owned and operated by Holland America Line. The Zuiderdam was built in Marghera, Italy, by Fincantieri, a firm specializing in modern cruise ships, and began service in 2002. The ship is the first in Holland America’s Vista-class series, the company’s new line of vessels featuring diesel-electric power plants for energy savings and an Azipod propulsion system for greater maneuverability. All Vista-class vessels are 81,769 gross tons and carry 1,848 passengers with a crew of 800. The Zuiderdam’s home port is Rotterdam.

Holland America Line designs its ships and markets its cruises for what the industry considers the premium markets. The Zuiderdam features Venetian-themed artwork and offers a variety of suites, staterooms, restaurants, lounges, and cafes, as well as recreational facilities including a theater, a golf simulator room, a casino, and a spa. Like other large cruise ship companies, Holland America caters largely to American customers. It runs vessels in all of the major cruise markets, including the Caribbean, Alaska, Asia, the South Pacific, Europe, and the Mediterranean.
