Designing your optimal TSHD

At Royal IHC, we believe that designing and constructing the most efficient TSHD is only possible in close collaboration with our customers. With more than a century of experience of building vessels – and hundreds of these still operating all over the world – our track record of listening to and understanding our customers’ operational needs speaks for itself.

Key to our longstanding success is knowing the circumstances in which a vessel will operate. From there, we build a specific business use case that will ensure a vessel is designed to deliver optimal performance efficiency for its required task, while resulting in the lowest operational costs.

We offer a service that includes in-house design, engineering and building of vessels, mission equipment and tools, thus allowing for expert guidance through every critical step of the shipbuilding process.

200 trailing suction hopper dredgers built, with an average lifespan of 35 years

We also have a reputation in the industry for building vessels with unprecedented levels of durability and longevity. Over the past 50 years, Royal IHC has delivered over 200 trailing suction hopper dredgers and the average lifespan of our vessels is approximately 35 years. This is not achieved by chance of course, but due to a combination of considered design, quality materials and proven construction techniques and detailing.

Given that there are many variables to consider when commissioning (including capital costs, fuel, insurance, maintenance, crew, emissions and environmental impact etc.) we draw upon our wealth of experience and work closely with our customers to determine the most versatile size of vessel for optimal dredge cycle performance, whatever the working conditions may be.   

Dredge 'platforms' enable quick decisions during concept design phase 

Our experience has allowed us to bring to the market a successful standard line of two standard hopper dredger model series (the Easydredge and Beagle series). These are more competitively priced than most of our custom-built models and are successfully proven in the markets they are aimed at. Having so-called dredge ‘platforms’ enables quick decisions during the concept design phase, as well as allowing for crossovers and comparisons with bespoke designs. 

A company doesn’t remain in business since the 17th century by standing still, so it’s reassuring to know that, by listening to the operational feedback of its customers, Royal IHC continues to innovate in its dredge design and construction. Recent examples have included hull shape developments; improved habitability, maintainability and ergonomics; mission equipment developments aimed at maximum durability and operational efficiency; draghead developments; and turbidity reduction via our ‘Plumigator’  anti-turbidity overflow system.

In the quest for maximum sustainability and lower emissions, several hopper dredgers have been built that are either running on LNG or are LNG-ready. Apart from looking towards alternative fuels with lower emissions, there is also a continuous quest for lowering the installed power through ever more efficient equipment. 

Furthermore, increased automation options have been explored to increase dredging operational efficiency and provide a longer lifespan for mission equipment. While the drive for emission-free vessels with zero turbidity is ongoing, our agenda for the future also includes the development of highly automated hopper dredgers with minimal or zero crew.
