Services

Drillship Conversion
Concept Design and Cost Estimating for DGs SEC Report (via AMC Consulting™) Upgraded Vittoria 10,000 Pilot Test (Allseas™) to small commercial system. Further upgrade to large commercial system after 5-years operation Transport simulation and cost estimates with limited buffer storage

Material Handling & Offloading
Offloading by slurry to a transport vessel in tandem with the mining vessel. Decanting is used in this example to dewater ore in buffer tank. Problem is how to remove nodules from hold of mining vessel and create slurry for transfer. Shown at left is a re-slurry pump.

Subsea Collectors & Risers
Complete digital twin / quasi-static modeling with computation fluid dynamics, material fatigue analysis and finite element analysis via OrcaFlex™ Simulations to test sensitivity to collector position & varying operating conditions. Development of Feasibility and Techno-Commercial Models related to the design, build and deployment of systems given the extreme environmental conditions.

Conceptual / Detailed Design & Testing
DRT can provide complete project engagement from conceptual designs to techno-economic feasibilities to full detailed design. Systems may include collector systems, risers, offloading systems, re-slurrification systems, pressure let-down systems, and material storage systems.

Mooring Design
Mooring systems are key components of a floating offshore wind farm as they ensure maintaining floating offshore platforms within a targeted area. DRT provides innovative floating offshore wind engineering and design services for the most popular platforms in the market today, including Barge, Semi-Submersible, SPAR & Tension Leg Platform-type.

Hydrodynamic Modeling and Mooring Analysis
DRT’s modeling specialists have extensive experience in deploying OrcaFlex allowing for dynamic analyses of offshore marine systems and modeling mooring systems of floating offshore wind turbines. Mooring systems optimization requires comprehension of the phenomenon driving and influencing the design.

Interface Mooring and Structure
DRT provides specialized design and analysis support for concrete connection structures for WindCrete and ActiveFloat designs to de-risk deployment. Connections are critical to any new design, as they tend to be rigid, and require careful assessment with concrete floaters with the moorings to assure design performance.

Subsea Geotechnical
Our team has developed unique expertise in downhole rock and soil sensor systems, analysis of in situ geotechnical data, general characterization of rock and soil strength. By carefully understanding the geotechnical aspects of the target geology, de-risking of the project is achieved.
Case studies
Deep-Sea Mining Digital Twin
Our client was developing a complex offshore deep-sea mining concept, which integrated various new and innovative systems and technologies.
We developed a digital twin of these integrated systems, including a full physics engine and offshore dynamics. System components that we integrated into the model included a production support vessel, offshore supply vessels, subsea harvesters, and a riser system.
This allowed us to optimize engineering and operational parameters, whilst allowing the client to clearly illustrate their proposed concept to partners and investors.
Deep-Sea Mining Development Plan
For The Metals Company’s successful 2021 IPO, Deep Reach Technology was the Qualified Person tasked with developing the offshore development plan and mining systems concept.
SEC requirements for mining companies include stringent disclosure requirements around mineral resources and operations. We are one of the only companies in the world with sufficient expertise and experience in deep-sea mining to be classified as a Qualified Person and be able to do this work.
Decades of experience in deep-sea mining planning, modelling, and real-life operations meant that we developed a comprehensive and accurate mine development plan, offshore system concept and various staged development systems for production support vessels. This was a core component of the technical plan that lead to a successful fundraise.
Offshore Wind Innovation for NOWRDC
As part of a project sponsored by National Offshore Wind Research and Development Consortium, we developed an innovative manufacturing and installation method for offshore floating wind farms.
Offshore floating wind is growing rapidly, and hundreds of floating substructures are required to support the vast number of turbines that will be installed. Manufacture and installation of huge offshore wind turbines is challenging, and new solutions are needed to meet this need.
Drawing on our expertise from other offshore engineering projects, including spar installation in offshore oil & gas projects, we proposed and are developing a new method for offshore manufacture of spar or buoyant tower wind turbines. This concept has the capacity to produce and install around 50 offshore wind turbines per year, for around 30-40% lower CapEx than current methods.
OTEC Concept Design & Evaluation
Offshore Thermal Energy Conversion is a renewable power generation concept that has been researched since the 1970s. It produces energy by harnessing the thermal gradient between warm surface waters and cold deep ocean waters at a depth of approximately 1000m.
We provided deep technical expertise around concept design, modelling and techno-economic analysis for an offshore floating OTEC project sponsored by Lockheed Martin and the Department of Energy.
In particular, we brought expertise in dynamic modelling of complex offshore structures, along with physical prototype testing, which allowed for hydrodynamic testing and load analysis of this unique structure.
