High efficiency loose soil dredging

Plain suction dredging is a method of dredging that involves using a suction pump to extract sediment. The suction pump is connected to a long pipe, which is used to transport the material to a designated location, such as a containment area or disposal site.

Plain suction dredging is commonly used in many industries, including construction, mining, and marine transportation. It is used to remove sediment and debris from waterways to maintain navigability, to extract valuable minerals and other resources from the bottom of water bodies, and to facilitate the construction of structures, such as bridges and piers.

The performance and reliability of dredging equipment depends largely on the selection and quality of the components of the dredge. ECTMarine dredge components will increase the performance and return on investment of your dredge or dredging project.

Customized PSD's

ECTMarine dredging vessels can be customized to fit the application fully. Customization not only can be done in the dredger itself but also in the way of building.

PSD Design & Equipment

For building projects abroad we offer Design & Equipment packages. with a partner as ECTMarine you will be able to build your dredger anywhere.

Plain suction dredger applications

Plain suction dredgers are typically purchased by organizations and companies involved in dredging operations for the purpose of: 

  1. Mining soils: soils kan contain valuable materials that can be sold or certain sand types are valuable for use in different applications. 
  2. Deepening of rivers, harbors and navigational channels, among others: when using the PSD for deepening, the soil must be free flowing and the bottom cannot be “flat” as a result.
  3. Tailings dredging: when the soil is loose and free flowing tailings can also be dredged in a mining situation.

Procurement trough tender process

Plain suction dredgers are capital infrastructural tools that in many cases are procured by government agencies, International organizations and large private companies that perform infrastructural projects for governments. Therefore the use of tender processes to aquire these dredgers are common. 

The tender process typically involves issuing a request for proposals (RFP) that outlines the technical specifications and requirements for the cutter suction dredger, as well as the evaluation criteria that will be used to assess the proposals. The RFP may also include information on the budget available, the expected delivery timeline, and any other terms and conditions that bidders must adhere to. To be successful in the tender processes, careful planning, evaluation, and monitoring is required. ECTMarine clients can be shipyards or contractors that are close to the entity that would like to aquire a plain suction dredger trough tender procedure.  

ECTMarine supplies Design & Equipment packages for local build by shipyards that would like to participate in a local tender. Especially for these situations we offer tender support. This means that ECTMarine will perform activities and supply support succesfully and completely hand in the tender.

Services are:

  1. Proposal writing and editing: Assistance in writing and editing the proposal to ensure that it meets the client’s requirements and presents the business in the best possible light.

  2. Research and analysis: Conducting research and analysis on the client’s needs, the competition, and the market to develop a compelling proposal.

  3. Bid management: Managing the bid process, including the development of timelines, coordination with team members, and ensuring that all required documentation is submitted on time.

  4. Compliance and regulatory support: Ensuring that the proposal meets all the relevant compliance and regulatory requirements.

  5. Presentation and pitch support: Providing support for presentations and pitches, including creating presentation materials, coaching team members, and conducting mock presentations.
