The aim of this project is to design, build, and commission such a solution. Below is a list of the envisaged key competencies that will be required, a high-level overview of the project requirements and some of the anticipated constraints to aid suppliers with determining whether adequate suitably qualified experienced personnel and resource are available to deliver such a solution. Value £3.5M

Desired competencies:

- Prior experience of designing and building maritime docking solutions. - Knowledge of Naval Architect design principals. - Knowledge of docking and undocking procedure for vessels. - Quality Assurance management of maritime manufacturing processes. - Experience with Research and Development type projects. - Experience in project managing high profile projects with significant number of stakeholders. - Adequate resource to deliver the project on time. - It is expected that the chosen supplier will have adequate suitable experience and qualification within their resource to undertake and validate load calculations.
