Dredge Yard delivers gate valves for trailing suction hopper dredgers - Dredging News Online

Dredge Yard recently delivered dredge valves of 600mm, 700m and 750mm internal diameter for the discharge pipelines on two trailing suction hopper dredgers.

All of the dredge valves were designed by Dredge Yard’s team of engineers using the latest design software. Fabrication was done in-house at Dredge Yard’s production facilities.

One of the special features of the valve is a steel reinforced rubber seal, making the seal very durable, enabling it to cope with abrasive slurries and to be able to open and close smoothly in difficult working conditions.

The body of the dredge valve was fabricated from high tensile steel and the valve gate is made of corrosion resistant, hardened steel, protecting it against the rust and wear. The outer surface of the valve was coated with a high quality marine paint to protect it against corrosion.

The inspection hole placed in the both sides of the valve body allows for easy inspection without dismantling it.

DREDGE YARD delivers dredge equipment for upgrading two TSHD

Dredge Yard has successfully supplied key dredge equipment for the upgrading of two existing TSHDs, the dredging capacity needed to be increased to enable the operator to complete dredging works in shorter time periods and in a more cost effective manner.

The TSHDs were upgraded by installing a shore discharge line on board and a bow coupling system on the stern of each dredger. The new discharge line will allow the dredgers to offload the material through a floating pipeline that will be connected to the bow coupling. The bow coupling also has the option for rainbowing through a nozzle if required.

The various components supplied with the discharge line include hydraulic gate valves, a complete bow coupling with structure, dredge pipes and bends. In addition, all hydraulic cylinders for the bottom doors were replaced by Dredge Yard.

The dredge bow couplings allow the dredgers to couple and decouple the floating discharge pipeline in the fastest and safest way. Locking parts of the couplings were made of stainless steel and the wet parts were made of high wear resistant material to increase the life time of couplings.

The dredge valves supplied are all hydraulically operated with the gates made from stainless steel and an innovative rubber seal reinforced internally by steel rings.

Dredge Yard in The International Conference on Waterways, Port Engineering and Dredging Technology in India

EADA (India) in association with Department of Harbour & Ocean Engineering AMET UNIVERSITY (Deemed) organized The International Conference on WATERWAYS, PORT ENGINEERING AND DREDGING TECHNOLOGY that took place on 2nd March in Chennai, India.

Some of the topics that were covered in the conference were about the new Dredging Techniques and Equipment, Contracts, Legislation and Engineer Determination , Planning and Execution of the Dredging Projects and of course Opportunities of Dredging in India.

Dredge Yard, main sponsor of the event, was represented by Manish Jangir, Senior Design Engineer, that spoke about the latest trend in dredging industry: CONVERTING AND UPGRADING DREDGERS. ,, All type of dredgers can be subject for modifications that can vary from replacing a single pump with more efficiency to the whole suction/discharge system of the dredger or literally converting existing barges and vessels into dredgers. “

Manish Jangir representing Dredge Yard in EADA

Upgrading of existing dredger systems is quite practical as it offers reusability and functionality of the old dredger with low investment.

Conversion of existing vessel into dredger can help in increasing the capacity and capability of the dredging companies in much lesser time with a huge saving in investment.

Modification of dredger is also needed when the dredger supplied may not meet up the requirements and slight changes in the parts or system can make it appropriate for the project requirements.

“Modifying or converting old vessels will always be considered the mostconvenient alternative due to the cost cuts, less time involved in the makeover of an old ship than building a new one and the possibility of customizing the vesselaccording to the customers’ needs.” added Manish Jangir.

EADA is a national chapter of EADA that provides a forum for the exchange of quality information on dredging techniques, technology and dredged material management, and for the development of good practice guidance.

New trend in dredging industry – CONVERTING AND UPGRADING OF EXISTING DREDGER

Engineering is continuously providing new technologies and solutions with time creating new options for users to be well-efficient and highly proficient. In the recent times, modification, conversion and upgrading of existing dredgers are proving to be good solutions for users to increase their capacity and capabilities with a reasonable amount of investment. Companies which cannot invest in a new dredger can convert their existing dredger, barges to a more functional and efficient dredger.

Upgrading of existing dredger systems is quite practical as it offers reusability and functionality of the old dredger with low investment.

Conversion of existing vessel into dredger can help in increasing the capacity and capability of the dredging companies in much lesser time with a huge saving in investment.

Modification of dredger is also needed when the dredger supplied may not meet up the requirements and slight changes in the parts or system can make it appropriate for the project requirements.

All type of dredgers can be subject for modifications that can vary from replacing a single pump with more efficiency to the whole suction/discharge system of the dredger or literally converting existing barges and vessels into dredgers.

Upgrading Dredge Pumps

Dredge pump or sand-slurry pump is considered as the heart of the dredger and plays the most vital role on the efficiency of a dredger.

Dredge Yard’s Senior Design Engineer , Manish Jangir, says: “Latest tools in the market like CFD and optimum design calculating software have widen the paths of having an efficient pump design for the same old pump without changing any fitting parameters or the connections like the flange.

After achieving the final design of the pump, the manufacturing is done by using the latest production techniques, molding software for casting, and strict metallurgical testings.

Upgrading suction and delivery lines

Suction and delivery lines of a dredger are the means of transport of slurry and the line design and components vary between dredgers. The efficiency of the dredger depends on the pump and the pumps efficiency certainly depends on the pipe line. And the maintenance cost depends on the quality and capability of the components. The major components involved in the pipe lines are: Pipe Pieces, Gate Valves, Suction Mouth, Swivel Bend, Bow Coupling, Turning Glands, Ball Joint Couplings, etc.

Few new trending components are discussed below:

Pipe pieces

Kabi Eisa, Production Manager at Dredge Yard describes the double wall dredge pipe as the newest trending product in the dredging market. He also adds that the Double wall pipes are highly wear resistant due to their special design where three layers of material have been used. It consists of wear liner, concrete and steel pipe where wear liner being the layer that will be in contact with the sand or slurry.

Dredge Valves

Dredge Gate Valves are slightly sophisticated components and for proper functioning, maintenance, it is very important to select the right type with right material and pressure handling capability for long life.

Upgrading split suction trailing hopper dredger

“For example, the dredger in the image didn’t have a discharge line and could only offload the material through its bottom doors.

Dredge Yard developed the complete suction and discharge line on the ship which includes several pipes, bends, dredge valves, and bow coupling. The nominal diameter of pipe is 750 mm.” says Michel Debo, Dredge Yard’s Operational Manager.

Converting hopper barge into trailing suction hopper dredger

Another example shows a barge in Brazil, capacity 800 m3, which is in process of conversion into trailing suction hopper dredger. A complete trailing suction system has been installed on the barge. The system consists of drag head, turning gland, gantries, sliding piece, pipes, bends, valves, pump and bow coupling.

Many hopper dredgers are upgraded by adding complete discharge line on the ship as pipes, bends, valve and bow coupling structure.

Modifying or converting old vessels will always be considered the most convenient alternative due to the cost cuts, less time involved in the makeover of an old ship than building a new one and the possibility of customizing the vessel according to the customers’ needs.
