Representative services

We lead you through every part of the process, making sure that you can capture the opportunity without getting lost in the complexity. With a unique focus on lifetime impact, we deliver services throughout the project lifecycle. We carry out early project feasibility and site assessments through to full operations and decommissioning planning for both fixed-bottom and floating technologies for offshore wind developments and related infrastructure such as ports, grids and industry-specific manufacturing facilities.

Sustainable offshore wind, powered by strategy

Having worked on some of the world’s premier offshore wind and associated infrastructure projects, we understand the nuances of permitting, design, construction and operations on a global scale.

We use that experience to hone our strategy, using smart, sustainable design and planning to proactively find the inherent risks and opportunities in projects. We use our global expertise and local presence to achieve fit-for-purpose approvals, develop plans to have the right materials and equipment where you need them, and design the grid connection to bring offshore wind power to communities safely, quickly and cost-effectively.

End-to-end insight. Everywhere you need it.

We’re trusted as a single source for offshore wind expertise, combining our global capabilities and experience with deep local insight into market forces and stakeholder requirements.

We bring best practice development and execution strategies from around the world, making sure you have a full view of potential options for your project.

Our technical expertise reaches from concept to decommissioning, including site assessment, stakeholder engagement, permitting and consents, electrical, civil/geotechnical, and structural design, ports and marine and program management. And because our energy team works across the full spectrum of the transition, including hydrogen development, grid modernization and transport decarbonization, we can help you evaluate the integration of your offshore wind project into the sustainable energy market.

We plan, design and implement microgrid and energy storage projects and programs around the globe, integrating new technologies into both existing and new electrical power grids to manage demand reliably, increase operational resilience and support energy supply decarbonization.

Introducing the future of smart grids, today

Smart, efficient power grids of the future will be made up of a network of campus- and community-scale microgrids. And these microgrids will leverage modernized transmission and distribution infrastructure. Traditional power consumers will transition to become producers (prosumers), who will offer generation, storage and ancillary services to a diversified energy market.

Energy storage will play a crucial role in this transition, stabilizing the electricity grid as more and more renewable energy comes online.

Experience spanning the energy storage industry

Our significant experience in energy storage ranges from market analysis (international and domestic), siting and permitting, sizing and design and project execution.

For rapid battery energy storage system (BESS) analysis we use our Rosetta methodology to define, direct and deliver long-term energy security. Rosetta integrates site data, opportunity analysis and strategic visioning to enhance the speed and quality of project quantification and facilitate faster decision-making.

The interactive platform relies on parametric energy modeling and a vast project database to fill the gaps in facility and performance data and inform cost estimates, savings and project viability.

One of our key goals? To develop resilient energy storage systems to determine demand charge savings during peak and off-peak periods.

Leading the industry by example, we work with our clients to develop regulatory guidance, technical solutions and operating standards for the production, transportation and use of hydrogen, including hydrogen carriers like ammonia and methanol.

Our independent expertise means we recommend and enable the right solution – hydrogen or otherwise – for your unique energy challenges.

Leading all stakeholders to clean hydrogen

With everything we do designed around our clients, we’re helping stakeholders harness the potential of hydrogen wherever it can be effective.

We’ve developed net zero feasibility studies, best available technology determinations and environmental impact assessments for hydrogen plants and pipelines globally. We have many years of project experience delivering hydrogen production facilities from electrolytic production to chemical synthesis with associated carbon capture and storage. We’re also driving transportation system decarbonization and the associated hydrogen mobility infrastructure.

Throughout, we support the creation of requirements for this important, emerging market, using our strong public and private sector relationships, and our work with government agencies on hydrogen deployment and subsidy/grant programs.

As leaders in the deployment of complex infrastructure, we develop business cases for hydrogen projects and then implement these projects on behalf of our clients. It’s an integrated approach that encompasses design, consenting, procurement, project management, commissioning and handover skills.

We deliver transformational outcomes, partnering with our clients to meet challenges head-on with knowledge, innovation and genuine partnership. We’re committed to servicing society and protecting the legacies of the projects and programs we manage. And we offer ongoing engagement throughout, from day zero to delivery and beyond.

Our experience spans over 20 countries, where we’ve designed and executed projects involving earth and rockfill, concrete arch, mass concrete and roller-compacted concrete gravity dams. As well as hybrid dams of timber crib, steel facing and concrete walls.

We are your trusted partners here to deliver expertise tailored to your unique hydroelectricity challenges.

Driving sustainable hydropower solutions

We see the big picture – from the initial dam to the final power outlet. We provide a full range of risk-analysis services associated with system integrity and consequence assessments, and we also map out transmission lines and the substations needed to deliver power to the consumer.

Our engineers are familiar with Kaplan, Francis and Pelton generating units as well as small hydro generators. Your hydropower project couldn’t be in safer hands.

With every project, we aim to drive sustainable, future-proof solutions tailored to you. It’s about delivering the best outcome today, while creating a renewable energy legacy for tomorrow.

Our team delivers comprehensive, cost-sensitive site assessments/investigations, permitting/compliance reviews, risk quantification and management services—for a single site or global portfolio with country-specific regulatory, linguistic, and cultural support tailored to meet our clients’ needs.

Sustainability and decarbonization advisory

Our sustainability and portfolio decarbonization advisory services help our clients on their journey to net zero carbon. We’re skilled in the development and delivery of water and power infrastructure and sustainability strategies such as renewable power generation, waste heat recovery, microgrid design, aquifer recharge and grey water reuse.

With many of our clients committing to operate on carbon-free energy, we are focused on developing new technologies, inventing new approaches and advocating for smart policy. Achieving this goal will require a collaborative approach, so we’re focused on several emergent technologies—advanced nuclear, enhanced geothermal, low-impact hydro, long-duration storage, green hydrogen, and carbon capture and storage to provide uninterruptable, efficient, and clean energy for data center infrastructure across the world. These alternative approaches of employing clean energy for grid balancing are already succeeding commercially and at scale, which means that carbon-based resources are simply no longer necessary and true round-the-clock clean energy is achievable.
