Protection Strategies for Subsea Wellheads in Iceberg Environments

The design of subsea infrastructure on the Grand Banks and, potentially, Labrador Sea must address the potential interaction with freely floating and gouging icebergs. Current practice is to protect the subsea infrastructure, such as conductors, wellheads and production trees, within massive excavations known as glory holes. For marginal fields or satellite wells, considerations of capital cost, construction cost and risk for developing the reservoir and protecting the assets may not be sufficient for project sanction.

Form & Language for the Astronomical Study of Hydrogen

This project undertakes the visualization of astronomical data in 3D enabling us to study phenomena such as expanding gas shells and rotating galaxies. We will develop a 3D mathematical model of astronomical observational data, apply this model to the data and display the data utilizing the technologies available through the Virtual Reality Centre.

Implementation of 3D Grid Movement Algorithms

This project involves the development and integration of mesh movement algorithms with the analysis software at Bombardier Aerospace. The algorithms are used to conform the volume mesh to the geometry as it evolves in an optimization cycle or in aero-elasticity analyses.

Study of Connection Times for Air Canada

The objective of the internship is to develop better thresholds for minimum connection times between flights. These thresholds must be large enough to reduce the risk of passengers missing their connecting flights due to flight delays. On the other hand, lengthier connection times lead to increased costs as planes and crews must wait longer between flights. The best compromises will be found by using historical data on flight delays to evaluate the effect of varying thresholds on the plane and crew costs using optimization models.

Improved Sizing of Defects Using Ultrasonic Phased Arrays

Olympus NDT is a world-leading manufacturer of innovative, nondestructive testing instruments that are used in industrial and research applications ranging from aerospace, energy and automotive to consumer products. The primary focus of this internship research is to sharpen images of cracks and imperfections that have developed in oil pipelines to within + 0.5mm using an ultrasonic phased array. Ultrasonic phased arrays are a relatively new technology for industrial testing and currently can size defects and cracks to within + 2mm.

Wave Diffraction of Floating Structures in Partially Frozen Seas

The objective of the proposed project is to develop a mathematical model to compute the wave diffraction force on a floating structure partially frozen or surrounded by an ice sheet. The horizontal and vertical forces on the cylinder and bending stress in the ice plate will be computed. The results will be compared with those by decoupled solutions. The research results will improve the understanding of the coupled wave-ice-structure interaction and will lay a foundation for the development of a comprehensive simulator to simulate floating structures in harsh environments.

Mathematical Modelling of Small Craft Motion

Simulation training is widely used in the aircraft industry to train pilots to operate aircraft. Likewise, ship bridge simulators are used to train the crews of large vessels. The efficacy of this type of training is recognized by international standards and is often required by regulations. A new application of simulation training technology is being developed by Virtual Marine Technology in co-operation with researchers at Memorial University. Specifically, they have developed immersive training simulators for small vessels such as lifeboats and fast rescue craft.

Nonlinear Dynamic Analysis of Mooring Lines in Deep and Shallow Water

The objective of this research project is to develop a computer program to predict the responses of mooring lines in waves and current. The nonlinear line tensions and anchor loads will be computed. By integrating the computer program into a vessel motion analysis tool, the development allows for the coupled mooring line and vessel dynamics computation. Validation studies will be carried out for mooring lines in deep water and in shallow water.

A Hierarchic Parametric Geometric Modelling for Aerodynamics Shapes

Bombardier Aerospace, a world-leading manufacturer of innovative transportation solutions, from regional aircraft and business jets to rail transportation equipment, is interested in technology developments that improve aerodynamic design methods. One of their objectives is to improve the process in which aerodynamic parameters are introduced within the optimization process to facilitate the application of geometric and aerodynamic constraints.
