Dredger Assessments

We assess, inspect and survey dredgers on a regular basis.

Reasons for these assessments are for instance:

  • Check against contractual demands
  • Improvement or modification plan
  • Modification or Major Conversions
  • Purchase or Charters
  • 2nd opinion
  • Mediation

Reviewing all aspects and details from HSE to crew abilities and Technical state to efficiency, spare-parts, wear and tear, ultrasonic measurements etc.

If you need to know everything about a dredger, you now know whom to turn to.

Trenching, burial and post lowering of cables and pipelines

Do you need to add experience to your team for trenching, burial or post lowering? We are there to help:

  • Work Method Statements
  • Dredging Contracts and negotiations
  • (Site) Management
  • Supervision and Client Representation
  • Engineering

Parts and special parts

When dredgers age, it gets harder to obtain certain parts. Sometimes we are able to source rare parts, old drawings or even casting moulds through our extensive network. If it don’t exist or cannot be manufactured anymore, we always find a way to overcome the problem.

Offshore Wind

On a regular basis we are involved in offshore wind projects. Installation of mono piles and scour protection or cable burial. Usually in the role of client representative, site management or a combination.

Study and public tender

For a European Authority who desires to maintain their own ports and waterways we conducted a study in order to answer their question “what dredger do we need ?”

The study comprised volumes and production calculations but also included environmental and economic aspects as the area is a protected and vulnerable nature reserve and a holiday hotspot. In addition we made a detailed technical specification of this dredger for the purpose of the public tender.

Project responsibility

With a chartered TSHD we took project responsibility for our client.
While our project team took care of the day to day business, we temporary transformed our clients own grab dredger into a highly efficient water injection dredger.
This saved multiple weeks of expensive TSHD input.

Dredging on LNG

As part of a study group Dredge Vision explored the possibilities of dredging on LNG.
The initiative was taken by the Dutch ministry of Economic affairs.

Next generation TSHD

Have you ever asked yourself why a TSHD design starts with the hull, while the money making part is mainly the dredging installation? Read more

Major conversion

Dredge Vision took project responsibility to convert an existing dry cargo ship into a Trailing Suction Hopper Dredger.
After a successful sea trial the vessel immediate set sail to its first dredging project.

Dredger design

Dredger design

For a client we designed a TSHD of 2700 m³ with two dredge arms and ice class

Major conversion

After the successful conversion of a dry cargo ship into a TSHD, we were approached by a shipyard to design a dredger based on their existing dry cargo hull.
With an innovative approach we achieved just that: a dredger as good as if it was purpose designed.

Bridge design

There is no room for error when creating a safe, ergonomic and efficient working environment for combined navigation & dredging
Therefore, although designed in 3D, we always build and test a full scale mock-up before the green light for production is given.

Intelligent anti-cavitation system

Cavitation not only causes damage, it also deteriorates your dredging process.
Our intelligent anti cavitation system is designed to operate on maximum vacuum, but pro-active responds if the cavitation limits are reached.
The system is successfully operating on dredgers since 2012 an can be installed as a stand-alone system that can simply be switched on and off.
