Every year, DPC magazine publishes the International Dredging Directory (IDD) using IHS Markit data. The IDD remains a comprehensive list of the world’s dredging companies, including branch offices, affiliates, and subsidiaries with their full address and contact information as well as technological specs about the dredger fleet.
For this year’s edition, we have not only compiled said data in tables, but wanted to give you an illustrated snapshot of the changing face of the fleet, which is why we have included colour-coded vessel counts for each dredger type as well as infographics presenting additional information throughout the publication.
To give you an overview, as of June 2019, 1,343 vessels were in service. Of those, 583 were trailing hopper suction dredgers, 391 cutter suction dredgers, 112 grab dredgers, making those three the most common types of dredger.
Looking at the capacity of those vessels, corresponding to the hopper capacity and size, ships have grown over the last four decades.
This trend looks set to last, with current orders focussing on large and mid-sized vessels. The dredger building boom of the last few years is however likely to see a decline. Peaking in 2016, with 51 vessels entering into service, newbuild numbers have now gone down with 38 vessels, TSHDs and CSDs, coming into service over the next two years.
