About The Centre

What is the WAMSS CDT?

The Wind & Marine Energy Systems & Structures (WAMSS) is an EPSRC-funded Centre for Doctoral Training (CDT), led by the University of Strathclyde, working collaboratively with Universities of Oxford and Edinburgh. The Centre aims to train the next generation of technical leaders, through doctoral studies, for the Offshore Renewable Energy (ORE) sector.

​

​

​

​

A student’s time in the EPSRC CDT in Wind and Marine Energy Systems and Structures is split into three parts: an academic training programme, a professional development programme (known as PETS) and a 3 year programme of research. 

​

During the academic training programme, students take short courses (“taught modules”) to develop their knowledge and understanding as well as participating in mini-projects and group projects, thereby introducing them to academic research. They are supported by academic and research staff from the Universities of Strathclyde, Oxford and Edinburgh.

The rest of the 4 year period involves an in-depth research programme leading to PhD, DPhil or EngD qualifications. In the majority of cases, the student’s project is carried out in collaboration with an industrial partner.

​

The core of the CDT is a research project work supported by formal education and training, but there is also a strong emphasis on the development of a team-based ethos combined with professional and personal development and strong links to industry. The Institute for Engineering and Technology (IET) and the Institute for Mechanical Engineers (IMechE) have accredited the CDT to provide a professional development programme leading to Chartered Engineer (CEng) status. This was the first doctoral training programme to be given such accreditation and gives students the opportunity to work towards Chartered Engineer status. Students use their research, industrial-facing and outreach activities in the CDT to count towards their application.

WAMSS Programme Structure

Track A is for students who wish to have their academic training programme to be concentrated in the first year of their 4 years in the CDT. Their research project is then completed over the remaining three years.  This means that a student has longer in which to choose their research project. The broad initial training programme can help to inform a student’s choice of research project. A timeline showing the first year programme for a track A student is shown below.

In order to maximise flexibility and to cater for a broad range of student and industry needs, the CDT consists of two distinct training “Tracks”. Each CDT cohort includes students from both Tracks and hence the academic training programme caters for both.

Track B is for students recruited to defined university, or industry-based projects, where the academic training is spread across the 4 years of research. On this Track, the academic training facilitates the doctoral research and broadens a student’s understanding.  This mode of delivery is better suited for students who are embedded/employed by companies following an EngD-type doctorate. A timeline showing the first year programme for a track B student is shown below.

Location

Track A students will be based at the University of Strathclyde for all 4 years of the CDT.
Track B students will be based at the University of Strathclyde for the first semester of the CDT. The remainder of the doctorate will be carried out at the host university: Strathclyde, Edinburgh or Oxford.

The Modules

The academic training programme is made up of 3 different types of modules: Core modules, guaranteed modules, and specialist modules. Every CDT student, regardless of whether they are Track A or Track B, are required to undertake and pass the 5 Core Modules and 3 other modules in order to graduate. Students may also take further modules to further their knowledge and understanding.

​

Each module is typically worth 100 hours of effort, with around 20 hours of taught material alongside tutorials, computer labs and visits. Coursework and oral exams are used to assess students’ knowledge, understanding and ability to reason.

​

Core Modules

All students complete the induction process and a set of 5 “Core Modules” within the first 5 months. These are based at the University of Strathclyde in Glasgow. A further compulsory module is taken in Year 2, based at the University of Oxford.

Guaranteed Modules

The Guaranteed modules are based at Strathclyde and Edinburgh. Track A students will take these classes straight after their core modules where as Track B students can decide to select these as their additional modules at any point in there studies.

Specialist Modules

Speacilist modules are additional modules run by each institute, since Track B students are required to selected 3 modules, these modules can be used for this purpose. Track A students can also take these modules if they are relevant for their studies.
