We design, build, maintain and operate turnkey tidal energy systems

Sustainable Marine offers a full suite of services required to deliver a successful tidal energy project. We have extensive experience with working in challenging coastal environments, and can work with you to design, construct, deploy the right system for the situation. Our tidal platforms can be deployed anywhere in the world and we are keen to work with partners who have local knowledge of their waters, regulations and requirements, and an in-depth understanding of the local energy markets, needs and opportunities, to develop profitable projects that can provide a range benefits to coastal and island communities.


These benefits include long-term and sustainable employment opportunities, increased resilience to disruptive weather events that are occurring with increasing frequency due to our changing climate, improved access to energy and energy independence, and enhanced security and predictability of supply from a non-polluting and renewable source.

As part of our turnkey solutions, our services begin with site surveying and evaluation. We then customize our PLAT-I platform to suit the location; we can vary the size of the platform to accommodate a range of turbine and rotor configurations. Our engineering team understands the key variables that impact system costs and performance. Matching the appropriate platform technology to the conditions that are experienced at a site is critical to the delivery of a successful project.

Planning a Successful Tidal Energy Project

1. Site Evaluation

  • Assess potential in terms of flow speed, depth, bathymetry, exposure, and access

  • Determine tidal coefficients and assess local factors that may impact availability and/or capacity factor

  • Evaluate energy demand, nature of connection (on or off-grid), and ability to match tidal energy to demand profile

  • Potential environmental impacts, constraints and ability to co-exist with other users

  • Regulatory environment, permitting & licensing processes, PPA terms, incentives for renewable energy deployments

2. Engineering

  • Specification of turbines and power system to match tidal resource, type of grid connection, and demand profile (may include storage)

  • Selection of most appropriate PLAT-I platform to suit the project and application

  • Design and specification of balance of plant; cabling and connectors, anchors & moorings

  • Installation and O&M strategies and planning

 3. Procurement and Construction

  • Supply of proprietary technology on a turnkey basis

  • Management of supply chain and procurement of balance of systems

  • Onshore system integration, assembly and commissioning

  • Construction of onshore balance of plant and grid interconnection

4. Installation

  • Installation of anchors, mooring, and underwater cables for power export

  • Launch, tow-out and installation, and activation of tidal energy platform

  • Installation and commissioning of environmental monitoring systems

  • Post-installation performance verification and remote monitoring
