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.

Ursa – for Työvene

The Ursa, a trailing suction hopper dredger (THSD), was built by the Työvene shipyard for the Maritime office of Gdynia, and is the first of their fleet.

C-Job was responsible for the concept, basic and detail design, and the integration of dredging equipment.

C-Job CSD Series 

The C-Job CSD Series is a flexible and adaptable concept design for mid-range cutter suction dredgers, with a dredge discharge diameter of 20-40 inches. The dredger design can be stationary, for use in the USA and other markets, or there’s the option to have installed power up to 30,000 horsepower if a self-propelled dredger is required.

Vox Amalia – for Van Oord

C-Job collaborated with Van Oord, a global leader in dredging and marine construction, for the development of the Vox Amalia, a trailing suction hopper dredger (TSHD) with a capacity of 18,900 m³. Van Oord provided the business case and operational requirements, while C-Job performed a feasibility study, concept design, basic design review, and detail design, and provided building supervision support.

Autonomous underwater maintenance dredger (AUMD)

C-Job’s autonomous underwater maintenance dredger (AUMD) concept is an innovative solution which supports maintenance in port environments. The AUMD combines the benefits of autonomous shipping with sustainable solutions from C-Job, creating a unique dredger design.

Bonny River – for DEME

C-Job was commissioned to develop the initial and concept design for this trailing suction hopper dredger (TSHD) on behalf of DEME, one of the world’s leading dredging companies. The Bonny River is a next-generation LNG-ready vessel, which is designed specifically to meet the challenges of dredging hard soils. It boasts a hopper capacity of 15,000 m³, and can operate in deep waters exceeding 100 meters.

St. Pierre – for STX Lorient 

C-Job developed the complete engineering package, covering concept, basic, and detail engineering phases for the 2,000 m³ hopper dredge St. Pierre. Designed for the STX Lorient shipyard in France, the vessel was specifically optimized for the challenge of extracting heavy coarse sand and gravel from deeper waters, further offshore, and often in heavy seas.
