      PROFILE

      Niall is an associate consultant of Tension Technology International. He is a hydrodynamicist and chartered marine engineer (IMarEST) with over 19 years’ experience in marine hydrodynamics in academic research, consultancy and commercial R&D settings. His experience covers seakeeping and mooring analysis, metocean condition assessment, measurement and modelling, tank and field testing, numerical modelling of wave energy converters and development of potential flow solvers.

       

      EXPERIENCE

      February 2014 – Tension Technology International Limited - Associate Consultant

      Carrying out consultancy work on moorings on behalf of clients and assisting with enhancements of the OPTIMOOR mooring analysis software.

      Recent consultancy projects include: outline mooring design and analysis for scale prototype trials of Marine Power System’s WaveSub wave energy converter (ORCAFLEX); review and validation of the DTOcean mooring design tool for marine energy converter farms; validation of mooring analyses carried out for quayside mooring of the Shell Prelude at the Geoje Shipyard (Optimoor); outline design and analysis of hawsers used to connect vessels deployed in ship to ship gas transfer (Optimoor) and validation of proposed moorings for vessels used for operation and maintenance at EMEC's Fall of Warness tidal turbine test site (ORCAFLEX).

      January 2010 – January 2014 AWS Ocean Energy Limited Senior Hydrodynamicist

      Seakeeping and Moorings

      Performed in-house analyses to assess seakeeping and mooring requirements for successive design iterations of the AWS III wave energy converter (WEC) and reviewed work completed by consultants.

      Metocean Condition Assessment

      Determined metocean conditions for energy yield and survivability assessments of the AWS III WEC and made assessments of site suitability for field trials of device subsystems.

      Liaised on a study of metocean conditions at the Costa Head wave farm site undertaken by the site developer (a consortium between Alstom and SSE) advising on metocean data of interest, relevant measurement and numerical modelling approaches and reviewing on-site measurements.


      Was responsible for wave measurements carried out during scale prototype trials of the AWS III WEC used to assess energy yield of device at Loch Ness in 2010.

      Device testing

      Assisted in field trials of a scale prototype of the AWS III WEC at Loch Ness in 2010 and in tank testing campaigns carried out to assess performance and survivability of successive iterations of the AWS III and device subsystems and reviewed energy yield calculations based on them.

      Performance Numerical Modelling

      Helped to initiate numerical modelling of AWS III device by subcontractors, advising company management and investors of the merits of potential modelling approaches and on the experience of subcontractors, and reviewed all work undertaken, helping to resolve some issues which arose.

      2001-2009 Jacobs Engineering - Numerical Modeller

      Coastal and estuarine waters modelling

      Undertook several modelling studies to assess metocean conditions for engineering design and the impacts of proposed developments on local coastal and estuarine processes including wave disturbance studies for Fraserburgh, Saundersfoot and Scrabster harbours; current and sediment transport studies for Burry Port, Martello Quays, Howbury Park and the Replacement Forth Crossing; wave modelling studies for the Aberystwyth Coastal Defence Strategy and the Replacement Forth Crossing. Also assisted with code maintenance of company’s operational Clyde Flood Warning system.

      Structural modelling

      Carried out several finite element analyses to assess the structural strength of maritime structures including analyses of Tay Road Bridge piers to assess requirements for additional ship collision protection and analyses of jetty structures at Faslane naval base to demonstrate that they satisfy design seismic and drop load safety cases.

      Seakeeping and hydrostatic analysis

      Performed seakeeping analysis for a floating RO-RO pontoon using the DNV WADAM software to confirm that the restraining piles are strong enough to keep the pontoon in position cases (12 Quays pontoon).

      Carried out a linear optimisation study to determine the optimum water ballasting of a floating RO-RO pontoon with numerous different sized ballast chambers solving a trim problem (Humber Sea Terminal).

      1998-2000 Department of Ship and Marine Technology, University of Strathclyde - Research Fellow

      Carried out an offshore industry initiated research project on wave loading on ROVs and other subsea apparatus during launch and recovery, using a combination of tank tests and numerical methods to quantify some nonlinear aspects of loading not routinely considered by operators.
