70-569: The December 26, 2015 arrival at the Port of Los Angeles marked the first time a ship of this size had been used in North America - previous routes for a ship this large were only from Asia to Northern Europe. CMA CGM Benjamin Franklin is about a third larger than the biggest container ships that typically visit the deep water ports of southern California. After departing Long Beach, she traveled north along

140-402: A dragline . This technique is often used in excavation of bay mud . Most of these dredges are crane barges with spuds , steel piles that can be lowered and raised to position the dredge. A backhoe/dipper dredger has a backhoe like on some excavators . A crude but usable backhoe dredger can be made by mounting a land-type backhoe excavator on a pontoon . The six largest backhoe dredgers in

210-480: A 5.5% increase over 2016's record-breaking year of 8.8 million TEU. It's the most cargo moved annually by a Western Hemisphere port. The port is the busiest port in the United States by container volume, the 19th-busiest container port in the world, and the 10th-busiest worldwide when combined with the neighboring Port of Long Beach . The port is also the number-one freight gateway in the United States when ranked by

280-482: A capacity of 6,000 cubic metres per hour (59,000 cu ft/ks). An even larger dredger, retired in 1980, was the U.S. Army Corps of Engineers Essayons , which was 525.17 feet (160.07 m) long. The Mallard II , a clamshell dredger that maintains levees in San Francisco Bay , has operated continuously since being built in 1936. Dredgers are often equipped with dredge monitoring software to help

350-652: A dozen pilots , including two chiefs. Pilots have specialized knowledge of the harbor and San Pedro Bay. They meet the ships waiting to enter the harbor and provide advice as the vessel is steered through the congested waterway to the dock. For public safety protection inside the port and of its businesses, the Port of Los Angeles utilizes the Los Angeles Port Police for police service, the Los Angeles Fire Department (LAFD) to provide fire and EMS services,

420-439: A few different types of dredge hoses that differ in terms of working pressure, float-ability, armored or not etc. Suction hoses, discharge armored hoses and self-floating hoses are some of the popular types engineered for transporting and discharging dredge materials. Some even had the pipes or hoses customised to exact dredging needs etc. Other times, it is pumped into barges (also called scows ), which deposit it elsewhere while

490-438: A large ship, and that ports would need to be modified before permanent large-scale implementation could commence. One such necessary modification is for the terminal cranes to be able to reach containers stacked to the full capacity of 10 high. The CMA CGM Benjamin Franklin is propelled by a MAN B&W 11S90ME-C9.2, a low speed, two-stroke diesel engine . The MAN B&W 11S90ME-C9.2 was designed in house by MAN B&W with

560-478: A long tube like some vacuum cleaners but on a larger scale. A plain suction dredger has no tool at the end of the suction pipe to disturb the material. A trailing suction hopper dredger (TSHD) trails its suction pipe when working. The pipe, which is fitted with a dredge drag head , loads the dredge spoil into one or more hoppers in the vessel. When the hoppers are full, the TSHD sails to a disposal area and either dumps

630-470: A plunger powered by a hydraulic piston is started with oil pressure. Oil pressure is regulated by a valve that is electronically controlled through the Engine Control System. Exhaust valves are opened by a two-stage exhaust valve actuator which is activated by oil delivered from an electronically controlled valve. By controlling these valves electronically, the combustion process is fully controlled by

700-496: A process known as dewatering. Current dewatering techniques employ either centrifuges, geotube containers, large textile based filters or polymer flocculant /congealant based apparatus. In many projects, slurry dewatering is performed in large inland settling pits, although this is becoming less and less common as mechanical dewatering techniques continue to improve. Similarly, many groups (most notable in east Asia) are performing research towards utilizing dewatered sediments for

770-425: A ship may be under. This electronic control of the start to finish of the combustion process is known as the Engine Control System. Fuel injection controls the speed in which the engine will be operating at, while the exhaust valves control the exit of combustion gases from the cylinder. The actuators for fuel injection and the exhaust valves are electronically controlled by the Engine Control System. For fuel injection,

840-411: A shipping channel through coral reefs . A bucket dredger is equipped with a bucket dredge, which is a device that picks up sediment by mechanical means, often with many circulating buckets attached to a wheel or chain . A grab dredger picks up seabed material with a clam shell bucket , which hangs from an onboard crane or a crane barge , or is carried by a hydraulic arm, or is mounted like on

910-518: A specialist floating plant , known as a dredger. Usually the main objectives of dredging is to recover material of value, or to create a greater depth of water. Dredging systems can either be shore-based, brought to a location based on barges , or built into purpose-built vessels. Dredging can have environmental impacts: it can disturb marine sediments , leading to both short- and long-term water pollution , damage or destroy seabed ecosystems , and can release legacy human-sourced toxins captured in

980-404: A water environment. Possible reasons for dredging include improving existing water features ; reshaping land and water features to alter drainage , navigability , and commercial use; constructing dams , dikes , and other controls for streams and shorelines; and recovering valuable mineral deposits or marine life having commercial value. In all but a few situations the excavation is undertaken by

1050-515: Is a bar or blade which is pulled over the seabed behind any suitable ship or boat. It has an effect similar to that of a bulldozer on land. The chain-operated steam dredger Bertha , built in 1844 to a design by Brunel and as of 2009 was the oldest operational steam vessel in Britain, was of this type. This is an early type of dredger which was formerly used in shallow water in the Netherlands. It

1120-684: Is a currently non-operational heritage trolley line for public transit along the waterfront in San Pedro . Prior to its closure in 2015, it used vintage and restored Pacific Electric Red Cars to connect the World Cruise Center, Downtown San Pedro, Ports O' Call Village , and the San Pedro Marina. Oceangoing ships visiting ports are a large source of nitrogen oxides in Southern California. Heavy-duty diesel trucks, that are also part of

1190-446: Is an independent, self-supporting department of the government of the City of Los Angeles. The port is under the control of a five-member Board of Harbor Commissioners appointed by the mayor and approved by the city council, and is administered by an executive director. The port maintains an AA bond rating, the highest rating attainable for self-funded ports. As of 2016 , the port had about

1260-550: Is less than 6000 TEU. However recently in 2016, container ships sizing from 12,000-14,000 TEU have been calling to U.S. ports in California. Notably, the CMA CGM Benjamin Franklin is the largest vessel to ever call to a U.S port. The Federal Maritime Commission has recognized the trend in increasing vessels size and U.S. ports have begun preparation in anticipation of the increased arrival of larger vessels. Major ports in

1330-424: Is mainly used in harbours and other shallow water. Excavator dredge attachments The excavator dredge attachment uses the characteristics of cutter-suction dredgers, consisting of cutter heads and a suction pump for transferring material. These hydraulic attachments mount onto the boom arm of an excavator allowing an operator to maneuver the attachment along the shoreline and in shallow water for dredging. This

1400-410: Is usually sucked up by a wear-resistant centrifugal pump and discharged either through a pipe line or to a barge. Cutter-suction dredgers are most often used in geological areas consisting of hard surface materials (for example gravel deposits or surface bedrock) where a standard suction dredger would be ineffective. They can, if sufficiently powerful, be used instead of underwater blasting. As of 2024,

1470-479: The Leiv Eriksson are: 46,000 cubic metre hopper and a design dredging depth of 155 m. Next largest is HAM 318 ( Van Oord ) with its 37,293 cubic metre hopper and a maximum dredging depth of 101 m. A cutter-suction dredger's (CSD) suction tube has a cutting mechanism at the suction inlet. The cutting mechanism loosens the bed material and transports it to the suction mouth. The dredged material

1540-612: The Alameda Corridor . In 2011, no American port could handle ships of the PS-class Emma Mærsk and the future Maersk Triple E class size, the latter of which needs cranes reaching 23 rows. In 2012, the port and the U.S. Army Corps of Engineers deepened the port's main navigational channel to 53 feet (16 m), which is deep enough to accommodate the draft of the world's biggest container ships. However, Maersk had no plans in 2014 to bring those ships to America. In 2024

1610-477: The Nile were channelled and wharfs built at the time of the pyramids (4000 BC), there was extensive harbour building in the eastern Mediterranean from 1000 BC and the disturbed sediment layers gives evidence of dredging. At Marseille , dredging phases are recorded from the third century BC onwards, the most extensive during the first century AD. The remains of three dredging boats have been unearthed; they were abandoned at

1680-499: The U.S. Coast Guard for waterway security, Homeland Security to protect federal land at the port, the Los Angeles County Lifeguards to provide lifeguard services for open waters outside of the harbor, while Los Angeles City Recreation & Parks Department lifeguards patrol the inner Cabrillo Beach . The port's container volume was 9.3 million  twenty-foot equivalent units  (TEU) in calendar year 2019,

1750-577: The "Bay of Smokes." The south-facing San Pedro Bay was originally a shallow mudflat , too soft to support a wharf . Visiting ships had two choices: stay far out at anchor and have their goods and passengers ferried to shore, or beach themselves. That sticky process is described in Two Years Before the Mast by Richard Henry Dana Jr. , who was a crew member on an 1834 voyage that visited San Pedro Bay. Phineas Banning greatly improved shipping when he dredged

1820-414: The Engine Control System. The frame of the cylinder is cast and fitted with access covers for the routine cleaning of the scavenge ports on the cylinder liner, a unique characteristic of two-stroke engines. The cylinder liner is produced with alloyed cast iron and contains scavenge ports as well as drilled holes for lubrication. Air intake takes directly from the engine room to the turbocharger fitted to

1890-542: The LA Waterfront attracts thousands of visitors annually. Remodel and reconstruction was approved by the Los Angeles City Council. Development is set to be completed in 2020. Construction is expected to begin in 2017 at a partial project cost of $ 90 million, paid by the developer. The San Pedro Public Market is expected to open in 2020, with demolition beginning as early as November 2016. The Waterfront Red Car

1960-415: The Port of Los Angeles has already surpassed its initial 2023 emission goals 8 years ahead of predicted time frame. The dramatic success to reduce emissions has seen a decrease in diesel particulate matter reduce 72%, sulfur oxides by 93%, and nitrogen oxide by 22% so far. The CAAP program was updated to 3.0 after this environmental successes of the initiatives. With the recent ramification of environment goals

2030-553: The United States have begun dredging for 50 ft berth/channel depths and heightening their crane fleets in order to accommodate the arrival of larger vessels Port of Los Angeles The Port of Los Angeles is a seaport managed by the Los Angeles Harbor Department , a unit of the City of Los Angeles . It occupies 7,500 acres (3,000 ha) of land and water with 43 miles (69 km) of waterfront and adjoins

2100-578: The West Coast of the United States, arriving at the Port of Oakland near San Francisco on December 31, and at the Port of Seattle on February 29, 2016. The U.S. tour was short-lived, however, as CMA CGM postponed deployment of megaships to the West Coast in May 2016, citing a lack of demand. In regard to U.S. port infrastructure, Marc Bourdon, president of CMA CGM American operations, states that while some ports are ready, most ports would have difficulty with such

2170-520: The beds of streams. During the renaissance Leonardo da Vinci drew a design for a drag dredger. Dredging machines have been used during the construction of the Suez Canal from the late 1800s to present day expansions and maintenance. The completion of the Panama Canal in 1914, the most expensive U.S. engineering project at the time, relied extensively on dredging. These operate by sucking through

The Banu Musa brothers during the Muslim Golden Age in while working at the Bayt-Al-Hikmah (house of wisdom) in Baghdad, designed an original invention in their book named ‘ Book of Ingenious Devices ’, a grab machine that does not appear in any earlier Greek works. The grab they described was used to extract objects from underwater, and recover objects from

2310-412: The channel to Wilmington in 1871 to a depth of 10 feet (3.0 m). The port handled 50,000 tons of shipping that year. Banning owned a stagecoach line with routes connecting San Pedro to Salt Lake City, Utah , and Yuma, Arizona , and in 1868 he built a railroad to connect San Pedro Bay to Los Angeles , the first in the area. After Banning's death in 1885, his sons pursued their interests in promoting

2380-675: The city of Los Angeles, funded and maintained by the Port of Los Angeles. In 2009, the Los Angeles Harbor Commission approved the San Pedro Waterfront and Wilmington Waterfront development programs, under the LA Waterfront umbrella. The LA Waterfront consists of a series of waterfront development and community enhancement projects covering more than 400 acres (160 ha) of existing Port of Los Angeles property in both San Pedro and Wilmington. With miles of public promenade and walking paths, acres of open space and scenic views,

2450-605: The construction industry. Dredging is a four-part process: loosening the material, bringing the material to the surface (together extraction), transportation and disposal. The extract can be disposed of locally or transported by barge or in a liquid suspension in pipelines. Disposal can be to infill sites, or the material can be used constructively to replenish eroded sand that has been lost to coastal erosion , or constructively create sea-walls, building land or whole new landforms such as viable islands in coral atolls . Ancient authors refer to harbour dredging. The seven arms of

2520-492: The dredge continues its work. A number of vessels, notably in the UK and NW Europe de-water the hopper to dry the cargo to enable it to be discharged onto a quayside 'dry'. This is achieved principally using self discharge bucket wheel, drag scraper or excavator via conveyor systems. When contaminated (toxic) sediments are to be removed, or large volume inland disposal sites are unavailable, dredge slurries are reduced to dry solids via

2590-482: The dredge operator position the dredger and monitor the current dredge level. The monitoring software often uses Real Time Kinematic satellite navigation to accurately record where the machine has been operating and to what depth the machine has dredged to. In a "hopper dredger", the dredged materials end up in a large onboard hold called a "hopper." A suction hopper dredger is usually used for maintenance dredging. A hopper dredge usually has doors in its bottom to empty

2660-425: The dredged materials, but some dredges empty their hoppers by splitting the two-halves of their hulls on large hydraulic hinges. Either way, as the vessel dredges, excess water in the dredged materials is spilled off as the heavier solids settle to the bottom of the hopper. This excess water is returned to the sea to reduce weight and increase the amount of solid material (or slurry) that can be carried in one load. When

2730-405: The engines. From the turbocharger, air is sent to be cooled through a sea water cooler then stored in a scavenge air receiver. This air is then sent to the scavenge ports on the cylinder liners. Exhaust from the exhaust valves are sent to a receiver to equalize the different pressures produced from each cylinder. The exhaust gases are then sent through turbochargers. The CMA CGM Benjamin Franklin

2800-487: The environment, including the following: The nature of dredging operations and possible environmental impacts requires that the activity often be closely regulated and requires comprehensive regional environmental impact assessments alongside continuous monitoring. For example, in the U.S., the Clean Water Act requires that any discharge of dredged or fill materials into "waters of the United States," including wetlands,

MAN B&W ME engines have design and performance characteristics in order to comply with International Maritime Organization Tier II emission regulations. This engine has electronic hydraulic activation in order to increase flexibility with regard to fuel injection and exhaust valve activation. These two factors are adjusted in order to match operating conditions that

3150-447: The hopper is filled with slurry , the dredger stops dredging and goes to a dump site and empties its hopper. Some hopper dredges are designed so they can also be emptied from above using pumps if dump sites are unavailable or if the dredge material is contaminated. Sometimes the slurry of dredgings and water is pumped straight into pipes which deposit it on nearby land. These pipes are also commonly known as dredge hoses , too. There are

3220-469: The material could well suit the building industry, or could be used for beach nourishment. Dredging can disturb aquatic ecosystems , often with adverse impacts. In addition, dredge spoils may contain toxic chemicals that may have an adverse effect on the disposal area; furthermore, the process of dredging often dislodges chemicals residing in benthic substrates and injects them into the water column . Dredging can have numerous significant impacts on

3290-460: The material through doors in the hull or pumps the material out of the hoppers. Some dredges also self-offload using drag buckets and conveyors. As of 2008 the largest trailing suction hopper dredgers in the world were Jan De Nul 's Cristobal Colon (launched 4 July 2008 ) and her sister ship Leiv Eriksson (launched 4 September 2009 ). Main design specifications for the Cristobal Colon and

3360-462: The most powerful cutter-suction dredger in the world is DEME 's Spartacus , which entered service in 2021. The auger dredge system functions like a cutter suction dredger, but the cutting tool is a rotating Archimedean screw set at right angles to the suction pipe. Mud Cat invented the auger dredge in the 1970s. These use the Venturi effect of a concentrated high-speed stream of water to pull

3430-426: The nearby water, together with bed material, into a pipe. An airlift is a type of small suction dredge. It is sometimes used like other dredges. At other times, an airlift is handheld underwater by a diver . It works by blowing air into the pipe, and that air, being lighter than water, rises inside the pipe, dragging water with it. Some bucket dredgers and grab dredgers are powerful enough to rip out coral to make

3500-525: The port received 3 cranes capable of servicing ships up to 18,000 TEU. Los Angeles and Long Beach ports were some of the least efficient in the world, according to a 2022 ranking by the World Bank and IHS Markit. The World Cruise Center, located in San Pedro, Los Angeles , beneath the Vincent Thomas Bridge , has three passenger ship berths. The LA Waterfront is a visitor-serving destination in

3570-521: The port's top exports were wastepaper , pet and animal feed, scrap metal and soybeans. In 2020 the port's top three trading partners were China (including Hong Kong ), Japan , and Vietnam . In 2022, the port, together with the adjoining Port of Long Beach , were considered amongst the world's least efficient ports by the World Bank and IHS Markit citing union protectionism and a lack of automation .

3640-521: The port, which handled 500,000 tons of shipping in that year. The Southern Pacific Railroad and Collis P. Huntington wanted to create Port Los Angeles at Santa Monica and built the Long Wharf there in 1893. However, the Los Angeles Times publisher Harrison Gray Otis and U.S. Senator Stephen White pushed for federal support of the Port of Los Angeles at San Pedro Bay. The Free Harbor Fight

3710-433: The port. During the 1920s, the port surpassed San Francisco as the West Coast's busiest seaport. In the early 1930s, a massive expansion of the port was undertaken with the construction of a breakwater three miles out and over two miles in length. In addition to the construction of this outer breakwater, an inner breakwater was built off Terminal Island with docks for seagoing ships and smaller docks built at Long Beach. It

3780-530: The port. In 1985, the port handled one million containers in a year for the first time. During the 2002 West Coast port labor lockout , the port had a large backlog of ships waiting to be unloaded at any given time. In 2000, the Pier 400 Dredging and Landfill Program, the largest such project in America, was completed. By 2013, more than half a million containers were moving through the Port every month. The port district

3850-667: The production of concretes and construction block, although the high organic content (in many cases) of this material is a hindrance toward such ends. The proper management of contaminated sediments is a modern-day issue of significant concern. Because of a variety of maintenance activities, thousands of tonnes of contaminated sediment are dredged worldwide from commercial ports and other aquatic areas at high level of industrialization. Dredged material can be reused after appropriate decontamination. A variety of processes has been proposed and tested at different scales of application ( technologies for environmental remediation ). Once decontaminated,

3920-476: The seabed to bring the sediment in suspension, which then becomes a turbidity current , which flows away down slope, is moved by a second burst of water from the WID or is carried away in natural currents. Water injection results in a lot of sediment in the water which makes measurement with most hydrographic equipment (for instance: singlebeam echosounders) difficult. These dredgers use a chamber with inlets, out of which
