Nautilus Minerals: First of Three SPTs Assembled (Canada)

Nautilus Minerals Inc. has assembled the Bulk Cutter (BC), which is the first of the Seafloor Production Tools (SPTs).

Nautilus’ CEO, Mike Johnston, said: “This is a major milestone for the Company, having the first of the three SPTs assembled. This achievement brings the Company all the closer to making seafloor mining a reality.”

Subsea vehicle designer and manufacturer, Soil Machine Dynamics Ltd (SMD) of Newcastle upon Tyne, UK, is the company responsible for building the SPTs for Nautilus. SMD are experts in the “marinization” of mechanical, hydraulic, electric and electronic equipment for use in a subsea environment (water and pressure immersion).

SMD uses this skill set as the basis of much of its existing product line in remotely operated vehicles and subsea trenchers.

The BC is the heaviest of the three SPTs, weighing 310 tonnes when fully assembled. It is designed to be the high productivity machine responsible for the bulk of production.

Some world class companies have been involved in the design of the SPTs:

– The cutting drum of the BC was designed and built by Sandvik (Austria), a world leader in hard-rock mechanized mining and rock cutting equipment. The designs are based on similar designs used on large continuous miner machines used in underground mining and construction;

– The track sets for all three SPTs have been designed and built by Caterpillar, based on an existing Caterpillar excavator track design. Modification to the track set for subsea operation and required cutting duty was completed by SMD in consultation with Caterpillar and Sandvik;

– The dredge pumps for all three SPTs have been supplied by Damen, one of the world’s leading dredge equipment suppliers and are based on existing catalogue designs used in the dredging industry;

– The hydraulic equipment for all three SPTs is based on existing off-the-shelf Bosch Rexroth hydraulic equipment, with adaptations by SMD;

– The flexible hoses for all three SPTs have been designed and supplied by ContiTech AG (Germany), and are very similar to the rubber hoses used in the dredging industry.

Companies and institutions involved in the simulations and test work of the BC include CSIRO, Cellula Robotics, Deltares, Istanbul Technical University, ContiTech Oil & Marine Corp and Paterson & Cooke Consulting.

We are proud to have such world class companies and institutions involved in the design and testing of these tools. The next step is to carry out commissioning and acceptance testing of the BC in parallel with assembling the other two production tools, the Auxiliary Cutter and the Collecting Machine,” concluded Johnston.

3rd International Congress Hydraulic Engineering Structures and Dredging

Russia’s leading maritime industry Media Group PortNews (www.portnews.ru) holds a traditional annual Congress “Hydraulic Engineering Structures and Dredging” in Moscow. 

The two-day Congress includes the 7th International Forum of Dredging Companies and the 3rd Technical Conference “Modern Solutions for Hydraulic Engineering”.

Infrastructure development is among the real sources of Russia’s economy growth. Construction of port facilities and new hydraulic engineering structures on the country’s inland waterways constitute an essential part of all infrastructure projects. It is important to take into account the best international practices to implement these projects effectively.

The program of the Congress will be devoted to the latest technologies for dredging and hydraulic engineering works. Speakers and delegates will refer to real projects to discuss specifics features of dredging works, as well as dedicated fleet and equipment involved.
