A new CSD 30″ – for the Port of Portland
To maintain its shipping channel, the maintenance dredger Oregon has been hard at work for the Port of Portland since its construction in 1965. Due to its age, the Port reached out to C-Job to create a concept design for a new CSD 30”, to replace the Oregon, which could run on marine diesel oil and also be methanol-ready.

New generation push boats – design for thyssenkrupp Veerhaven
thyssenkrupp Veerhaven is exploring opportunities for a new generation of climate-friendly pusher boats: an EU Stage V emission standards push boat, and/or a dual-fuel methanol-diesel push boat. C-Job provided two different concept designs for each type of vessel, which had to navigate the river Rhine, deliver low OPEX, and provide good crew comfort.

Nuclear-powered commercial vessel
Research by C-Job demonstrates the potential for nuclear energy to become an alternative energy source which could contribute to the decarbonization of commercial shipping. This is in part due to the development of small modular reactors (SMRs) and advances in nuclear technologies. Additional C-Job studies explore new economical design speeds when using nuclear energy as a propulsion source for future cases.

E-Pusher 1 – for Kotug
C-Job worked with Padmos, a family run shipbuilder, on behalf of their client and shipowner, Kotug. In 2021, Kotug launched its E-Pusher concept of fully electric pusher boat and barges, which are a world first. The concepts were created by Kotug, and C-Job collaborated with Padmos on the basic and detailed engineering for the first of these vessels, the E-Pusher 1.
