Ben Andrew
Director, UK

About
Ben has over 17 years of specialist engineering experience in the design and analysis of offshore platforms, foundations, cables, and riser systems. He has held numerous project management and technical leadership roles on a variety of projects from concept through to detailed design based out of our London, Kuala Lumpur and Houston offices.
As one of the UK directors, Ben’s current focus is on the development of our minimum facilities platforms and fixed offshore wind offerings for the European, Middle East and Africa markets. Ben is a graduate of Oxford and Imperial Universities with a Bachelor’s degree in Mathematics, and a Master’s in Quantum Physics.

Novel, multi-disciplinary concept feasibility evaluation
Global expansion of fixed wind into new regions and deeper waters brings a new set of challenges and considerations for offshore wind developers. Where monopiles were often the top choice, foundation selection is becoming increasingly development specific and requires a more comprehensive investigation prior to selection.
To simplify this extremely complex decision, we use a novel concept screening approach that reviews a wide range of criteria to validate foundation suitability. We assess everything from soil, seabed interaction, fabrication, installation, operations and environmental impact, to the levelised cost of energy (LCOE) over all phases of the lifecycle, factoring in integrity management, life extension and decommissioning. Ultimately this takes any of the guesswork out of foundation selection and eliminates any costly surprises later in the project.
Our goal is to develop the optimal solution, not just something that does the job. We consider every aspect of the project lifecycle to identify where we can create cost and schedule efficiencies later in the project during fabrication, transportation, installation, operations and maintenance.
Holistic systems approach to design
Our meticulousness doesn’t stop with the feasibility assessment. We look at the bigger picture during engineering and design too. Our goal is to develop the optimal solution, not just something that does the job. We consider every aspect of the project lifecycle to identify where we can create cost and schedule efficiencies later in the project during fabrication, transportation, installation, operations and maintenance.
Optimised installation strategies that reduce time to “first wind”
Leaning on our extensive experience delivering minimum facility platforms, we have created opportunities to lower installation costs and reduce the time to “first wind”. Partnerships with local manufacturers and fabrication yards and creative approaches to installation and scheduling have enabled us to streamline our delivery processes as well as minimise the environmental impact of the project.
In-house geotechnical expertise
We leverage the expertise and experience of our in-house geotechnical team in all our fixed wind projects to optimise design and installation to meet local environmental regulations. This could include proposing solutions that limit the disturbance on the soil or reduce noise.
