DSC Provides Dredges with Tier 4 Certified Caterpillar Engines

In February 2017, DSC Dredge, LLC of Reserve, Louisiana, delivered its first dredges, equipped with a Tier 4 Final C32 ACERT Caterpillar engine to a U.S. mineral company. 
This Shark Class Dredge features an 18-inch hull-mounted dredge pump and 300 hp cutter drive assembly, and has a dredging depth capability of 56 feet. DSC supplied stainless steel hydraulic fittings and used anti-corrosion building practices, as the dredge will be working in a corrosive environment. The minerals company also purchased an anchor barge fabricated by DSC, which included a Tier 4 Final engine for the hydraulic winch drive system.
The U.S. Environmental Protection Agency (EPA) Tier 4 Final emissions standards went into effect for dredges last year. Engines ranging from 2,682 to 4,962 hp (2,000-3,700 kW) were first affected by the standards. But by this October (2017), all new engines with a maximum power of 804 hp (600 kW) and greater must meet U.S. EPA Tier 4 Final emission standards.
The C32 Tier 4 Final engine is a 32-liter 12-cylinder V-engine with horsepower ranges from 1,000 hp to 1,125 hp. The C32 has torque of 4,056 foot-pounds at 1,200 rpm. David Ezell, OEM

C32 ACERT Caterpillar engine.

account manager for Michigan CAT said that Caterpillar was able to achieve the Tier 4 Final regulations in the C32 with the use of the Caterpillar NOx Reduction System and dual maintenance-free diesel oxidation catalysts (DOC).
This summer DSC also equipped three new 18-inch Shark Class portable cutter suction dredges in Bangledesh with Caterpillar Tier 4 C32 ACERT diesel engines.
DSC said the engine design coupled with an advanced hydraulic system gives the engine high fuel efficiency and an extended life. The hydraulic system is load sensing and pressure-compensated to reduce the required cooling, tank capacity and filtration as well as power consumption. The Shark Class Dredge has an 18-inch hull-mounted dredge pump and 300 hp cutter drive assembly, with a dredging depth capability of 56 feet. 
Two of the three dredges have been shipped to Bangladesh, where contractors will work to restore navigability to rivers, streams and canals that fall under the scope of the Bangladesh Inland Water Transport Authority (BIWTA) and Bangladesh Water Development Board (BWDB).
DSC previously supplied an 18-inch Shark dredge and two 24-inch Marlin Class dredges to a contractor in Bangladesh following a study by BIWTA that called on private contractors to meet the dredging demands the rivers required. 
The third dredge under this contract is scheduled to be completed and shipped in February 2018..

JFSE Patents Jetting System
Global subsea excavation specialist James Fisher Subsea Excavation (JFSE), a part of James Fisher and Sons plc, has patented a new centrally located jetting system for its mass/controlled flow excavation (M/CFE) equipment spreads. 
The traditional design places jets at the side of the M/CFE tools, but the new high velocity water jet is placed centrally, giving excavators double the strength when cutting soils. New technology also reduces velocity degradation. 
The jet’s increased capabilities will decrease operational time and reduce the need for additional equipment to complete projects. M/CFE spreads are used for moving sand, silt and mud, clay and rock dump for work such as pipeline and cable trenching, deburial, rock dump dispersal and seabed clearance. 
The jets are being fitted to JFSE tools in the UK, UAE, Singapore, Venezuela, USA, Brazil, China and Mexico. The company has access to bases and expertise in 40 countries through its association with James Fisher and Sons.

Damen Launches Online Calculator for Project and Dredging Equipment Planning
Damen has introduced a free online tool designed to help dredging contractors perform project calculations and choose the correct equipment for projects on which they bid. 
Without the calculator, contractors must accurately calculate by hand the estimated production of each jobsite to determine what dredging equipment is needed and return an accurate project quotation. This is time consuming and costly.
Named Sandy, the calculator takes defining characteristics of the job site entered by the contractor and provides detailed advice on which dredge should be mobilized, as well what supplementary equipment, such as anchor booms and spud carriages, will be needed to increase efficiency. Pump, cutter and swing production are all shown.  
Damen said this calculator will improve the process for contractors when bidding on any dredging project. To access the tool, visit www.dredgefinder.com.


TSHD Scald Hits the Belgian Market
Faasse Groep announced the launch of a new trailing suction hopper dredge Scald, which was constructed by Scheepswerf Gebr. Kooiman B.V. at Zwijndrecht, the Netherlands. The dredge was delivered by Kooiman at the beginning of July.
The overall design is to provide an innovative, efficient and environmentally friendly dredge, compact enough to work anywhere and undertake diverse activities. The dredge has an 1,800 square meter capacity and special maneuvering capabilities that rely on a lifted wheelhouse and four rudder propellers. It was built on the freighter Furtura Carrier, which was shortened 20 meters (about 66 feet) to provide further maneuverability. 
Corrosion-resistant stainless-steel parts were used on the deck, dredge pipe wire winches were moved to the lower deck, and the bottom doors are equipped with levers, instead of chains and cylinders, all with an eye toward safety and ease of maintenance. The dredge has a sand transfer installation with jet pumps to both direct the material in the hopper and provide desalinization of sea sand through the addition of freshwater. There are six bottom doors for dumping.
The Scald works in the Belgium market for maintenance dredging, supplementation, spraying and sand winning activities.

Kruse Integration Develops More Efficient Gate Valve System
Kruse Integration has developed the CONTROL-FLO gate valve system to better control and maintain suction velocity. The gate valve is sized for each dredge pump and pipe and comes with an industrial enclosed vacuum transmitter, discharge transmitter and optional flow meter. The system has a touch screen control so operators can set limits, pre-acts, sensor calibration scaling and stroke speed. Real time values and the position of the gate valve can also be viewed on the touch screen. Previously suction relief valves stayed fully opened under high vacuum speed, no matter what conditions required. The new valve opens just the required percentage to maintain velocity while keeping maximum vacuum density.

Weeks To Build New Cutter Suction Dredge
In July, Weeks Marine Inc. (WMI) announced the construction of a new $60 million, 30-inch hydraulic cutter suction dredge, the JS Chatry. The dredge is named for Senior Vice President and Manager of Weeks Marine’s Dredging Division, J. Stephen Chatry. Construction is underway in Belle Chase, Louisiana, at C&C Marine and Repair.
“While the national coastal restoration and protection market is growing, we are especially optimistic about the market here in Louisiana. We have taken note of the Governor’s and the Legislature’s commitment to the masterplan and the protection of critical dedicated funds for their intended purpose,” said Richard S. Weeks, WMI President. “I am also very happy and proud that our newest dredge is named for Steve. He is a life-long Louisianan and has been a key member of our team as we have grown the business in Louisiana and throughout the United States. Finally, I hope Governor Edwards, Senators Cassidy and Kennedy, Representative Garret Graves and, our great congressman and champion, Rep. Steve Scalise, and other Louisiana leaders will be able to join us when we christen the Chatry.”
The JS Chatry is 310 feet long and 72 feet wide. The dredge’s pumps are powered by GE Tier IV diesel electric engines. Those engines and others provide 23,269 total installed horsepower, with 3,000 hp on the cutterhead. When the dredge is not offshore, it is equipped with a walking spud carriage for efficient work in inlets and in protected waters. 
In 2011, WMI announced a five-dredge, $200 million-plus capital investment initiative. The JS Chatry will be WMI’s sixth major dredging capital expenditure since that announcement. 
This fall, the $110 million 8,500 cubic yard hopper dredge Madalen will be christened in New York. The dredge is now in the water being fitted out and preparing for sea trials.
