PhD Studentship in Green Tribology: Degradation and Lubrication of Stern Tube Seals

Imperial College London

Department of Mechanical Engineering

Project Description

Applications are invited for a fully funded research studentship in the field of Tribology, leading to the award of a PhD degree. The project starts as soon as the post is filled, and runs for four years.

The project: Stern tube seals are elastomeric seals used in seagoing vessels. Their two main functions are to prevent water ingress into the stern tube and to minimize lubricant spillage into the marine environment and the engine chamber of the vessel. Due to environmental concerns, the use of mineral oils for maritime applications that interface with water is not desirable, and a range of bio-friendly lubricants has been introduced. However, these lubricants cause accelerated degradation of the seals, affecting their functionality and durability.

The aim of the research is to investigate the fundamental degradation mechanisms due to lubricant interaction with the sealing system. We will develop new experimental setups and numerical models to assess and describe the degradation of the seals and link this to the functional performance. This PhD studentship is part of a larger project, and the PhD student will work alongside another PhD student, based at the University of Twente, who will focus on the lubrication aspects of the sealing system. The industry sponsor, AEGIR-Marine, is closely involved in the project and part of the PhD project will be spent at their R&D facilities in the Netherlands, investigating the upscaling of the obtained results to actual seals.

Funding Information

The post is supported by a bursary and fees at the UK student rate provided by the Materials Innovation Institute M2i in collaboration with AEGIR-Marine BV. Candidates should fulfil the eligibility criteria for the award. Please check your suitability at the following web site: EPSRC Eligibility.
