When storing and retrieving large quantities of aerial surveillance video to be used as evidence, it must be possible to validate video as authentic without relying on secret knowledge. Part of the solution to this problem involves a novel combination of cryptography techniques used in blockchains and elsewhere together with computer filesystems, allowing data to be stored in a way that can be easily authenticated.
The proposed research project focuses on the development of a novel model for the computation of sea ice parameters in near real- time relying on satellite data. The interdisciplinary team will investigate solutions for high performance computing to monitor sea ice and calculate ice parameters with the high spatial resolution. This project includes R&D activities in sea ice modeling, calculating parameters of ocean interaction with sea ice and designing algorithms for satellite data processing and analysis.
Newfoundland oil and gas industry needs unique engineering solutions for offshore structures and operations because of harsh environment. Drifting icebergs, if collide with an offshore structure, may cause serious damage leading to economic losses, ecological problems and loss of human lives. To protect the structure, icebergs can be towed away; however, it is a complicated process, especially when the underwater part of iceberg is hidden. This project contributes to a new technology that can be used onboard of towing vessels to assist captains when taking their decisions regarding towing.
Offshore Newfoundland is an ice-prone environment which holds valuable natural resources. Better understanding of the ice environment and ice characteristics in this region is essential for safe and economical offshore activities.
Climate change continues to shrink the sea ice in the Arctic. Consequently, there is an ever-increasing trend of industrial and shipping activities in the Canadian Arctic. This results into a high risk of accidental or deliberate release of oil-related pollutants in the Arctic waters. Satellite remote sensing is a key component in spill detection as an essential step towards any remediation and cleanup effort. Thus, this project proposes to develop a detection algorithm based on microwave satellite data that can be incorporated into a high-level oil spill alarm system.
Sea ice thickness measurement is very important since it can be considered as an indicator of the state of ocean circulation and associated air-sea heat exchange within the Polar Regions. As a result, it can have a significant impact on global heat balance and ocean thermohaline circulation. However, obtaining sea ice thickness in a large area with sufficiently high accuracy and sensitivity is very challenging since it shows a great amount of spatial and temporal variability. The approaches reported in the past have significant restrictions in penetration depth, sensitivity and logistics.
Large amounts of crude oil and natural gas are located deep beneath Canada’s ocean floors. Currently, the offshore oil and gas industry makes a significant contribution to Canadian economy. Proper geotechnical modeling of seabed sediment is very important for safe, economic and reliable development and operation of offshore systems. The proposed research will advance the technologies required in the design of offshore foundations and anchors, subsea pipelines and risers.
Subsea pipelines play a significant role in transportation of hydrocarbon. In deep water trenching is difficult and therefore pipelines are often laid on the seabed. However, these pipelines could be penetrated into the seabed a fraction of its diameter during installation. Pipelines might experience thermal expansion due to low ambient and high internal temperature during operation cycles which can cause pipelines to expand axially and buckle laterally.
Pile foundations have been widely used in many offshore structures and oil and gas development programs such as tension leg platform, jack up platform, spar platform, and mooring of floating production, storage and offloading units (FPSO) units. The FPSO units are usually moored to the seabed with various kinds of anchors, including offshore piles. These piles are subjected to inclined upward load from FPSO. The objective of this research is to develop advanced method to estimate load carrying capacity of offshore mooring piles in sand subjected to inclined loading.
An understanding of the soil load and restraint on pipelines due to relative pipeline/soil movement is required to assess the pipeline mechanical response that may affect pipeline serviceability or integrity. Current engineering practice for pipeline/soil interaction is based on idealized structural-based numerical models that evaluate pipeline mechanical response using beam elements and soil behavior using discrete spring system. The soil spring are characterized by independent load- displacement relationships for only principal directions (i.e.
