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.
About the project

A versatile, methanol-ready CSD

C-Job designed the new CSD for the maintenance of Portland’s inland waterways and to work in high currents.

On the concept design, we cooperated on this with DE Klop, who supported with dredging production calculations as well as equipment and cost estimations. The maintainability of the vessel was optimized, and our design integrated main cranes, overhead cranes, crane beams, hatches for maintenance, and workshops.

In the expectation that methanol bunkering would be possible in the future, a methanol-ready vessel was important to our client. We fully integrated both methanol and MDO tanks in the vessel, creating a standout design compared to conventional CSD designs, and the new stationary dredge now offers increased redundancy for the Port of Portland.

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.

Lorraine Hooks – for Mike Hooks LLC

C-Job completed the concept, basic, and detail design, plus systems integration for the 27-inch cutter section dredger Lorraine Hooks, for US dredging company, Mike Hooks LLC. We collaborated closely with SPI/Mobile Pulley Works (MPW) who constructed the dredge equipment in Alabama, and Southwest Shipyards in Texas, who built the vessel. The Lorraine Hooks was delivered to its owner in 2023.

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.
