The chemical tankers have been in service for the materials manufacturer, Covestro, on the river Rhine and its tributaries for several weeks.
The striking colours of both the new ships represent the cooperation and partnership between HGK Shipping and Covestro.
‘Courage’ and ‘Curiosity’ are some of the most modern and innovative vessels afloat. The hulls of the shallow-water vessels, which are 93 metres long and 10.5 metres wide, have a very bulky and lightweight design with an unusual stern and bow shape. All the components
installed on board have been tested and optimised to reduce the required draught and weight.
Outstanding load capacity
By using two rudder propellors with comparatively small dimensions, HGK Shipping has managed to achieve outstanding load capacity and ideal shallow-water operations. As a result, the two sister vessels can carry a load weighing 160 tonnes in a draught of just 1.00 metres and still be fully operational and manoeuvrable.
The ‘Courage’ and ‘Curiosity’ are setting new standards in terms of sustainability. They have an efficient diesel-electric drive system, and this reduces CO2 emissions by up to 30 percent compared to conventional vessels that are currently in service. Emissions of particulate matter and other polluting substances have also been cut significantly.
Norbert Meixner, the business unit director Liquid Chemicals at HGK Shipping, said: “We want to create sustainable and reliable transport chains in conjunction with our customers. The ‘Courage’ and ‘Curiosity’ enable us to take a huge leap forward in this respect.
Milestone for inland waterway services
“Thanks to the vessels’ design, which allows us to use different drive systems, we’ve set another milestone for inland waterway services, but also in our role as a partner for the industry in the joint battle against greenhouse gas emissions.”
All the new vessels introduced by HGK Shipping during the last two years have also been planned and completed so that they can use future fuels or H2. The ‘Courage’ and ‘Curiosity’ have been designed per this concept. The hull has two empty areas, so-called void spaces, which can be equipped with storage solutions and the necessary technology for using alternative energy sources later.
“We’re not only able to organise our supply chains on the river Rhine in a more reliable way with the two new vessels, but already make them more sustainable too. When we re-equip them to use renewable energy sources in future, we can take an important step along the road towards climate neutrality and the circular economy.
Hydrodynamic optimisation
“We’re looking forward to continuing to follow this course together with HGK,” says Dr Uwe Arndt, the head of logistics EMLA at Covestro.
The ‘Courage’ and ‘Curiosity’ have been designed by the team at the HGK Shipping Design Centre from the original concept onwards; it has also performed the engineering work and developed the hydrodynamic optimisation – and has completed this up to the delivery time.
The Severnav Shipyard in Romania constructed the hulls. HGK Shipping’s turn-key partner, the De Gerlien van Tiem B.V. shipyard in the Netherlands, was responsible for the construction work until the vessels were delivered.
