Key Personnel
Arran Armstrong
Technical Manager, UK

About
Arran is 2H’s Geoconsultancy Technical Manager with an extensive career in offshore data acquisition, project management and geo-engineering consultancy. Arran joined the offshore industry as a graduate with RACAL in 2000, during this early time in Arran’s career he was primarily involved with geophysical and geotechnical offshore acquisition projects. After a period of time Arran specialised in geotechnics and geotechnical data acquisition, specifically with heave compensated geotechnical drilling vessels. In 2011 Arran moved onto Geo-engineering consultancy, applying his operational and technical experience gained as a site investigation contractor to provide clients with the knowledge they need to successfully meet their development design objectives. Now, as 2H’s Geonsultancy Technical Manager, Arran looks after our clients geo-engineering challenges whilst integrating with the other 2H engineering disciplines to provide our clients with holistic, turnkey engineering solutions.
Scott Duncan
General Manager, UK

About
Scott is General Manager of our Aberdeen office. He is a chartered mechanical engineer with the IMechE and has 6 years’ experience in the energy industry with notable experience in design, verification analysis, integrity management and testing of flexible risers and umbilicals systems.
Primary areas of specialist expertise include flexible riser annulus testing, FEED and detailed design of flexible riser systems, global and local wave induced fatigue analysis and mooring line failure analysis. Scott also has experience with top tensioned risers, wind turbine monopiles and fixed wind cable burial risk assessments (CBRA).
Scott has spent time working in 2H’s Woking and Houston offices and has extensive experience using OrcaFlex, Flexcom, MATLAB, ANSYS Workbench, GIS and 2H’s proprietary processing software.

Yusuf Arikan
Senior Project Manager, USA
About
Yusuf Arikan has over 15 years of structural engineering and project management experience in the design and analysis of various offshore structures including hydrodynamics of various floating offshore wind foundations. In recent years, he has been extensively involved in floating offshore wind projects, specifically the coupled assessment of the floater & turbine, and the design and analysis of mooring systems and power cables.
Yusuf holds a Bachelor’s degree from Bogazici University, Turkey and a Master’s degree from the University of Houston. He is a registered Professional Engineer (PE) in Texas and Project Management Professional (PMP).

At 2H, we deliver comprehensive engineering services for inter-array and export cable systems across fixed and floating offshore wind projects. Our expertise in cables spans the full lifecycle from early feasibility and cost optimisation studies through to detailed design, procurement and installation support, and long-term integrity management.
In a strategic partnership with Vekta Group, we combine our collective and extensive static and dynamic cable engineering experience with advanced modelling and digital tools to deliver safe, efficient, and cost-effective cable solutions tailored to each project’s unique environment.
We integrate electrical, thermal, mechanical and route layout engineering, with detailed CAPEX, OPEX, and LOSSEX modelling to optimise ROI and minimise LCOE, considering industry fault rates and repair cycle times.
For floating wind we are leading the way in defining design and qualification guidelines for dynamic cables and the need for integrated design of HV power cables with the mooring and substructure systems to maximise reliability and LCOE of the system.
