Ocean Environmental Design Lab
Machine-translated · View original
A lab that studies technologies for extracting ocean resources and energy with minimal environmental impact.

AboutAbout the lab
Aiming to create new technologies that make use of the sea's bounty
The Ocean Environmental Design Lab studies new technologies for extracting the resources and energy of the sea.
The lab proposes and evaluates technologies that make it possible to extract them safely while keeping the burden on the natural environment to a minimum.
Its main themes are the extraction of deep-sea resources, natural energy from the sea, seawater desalination, and predicting the environmental impact of ocean development.
Key terms
- Flow assurance
- Research on keeping multiphase flow transported soundly through pipes laid on the seabed
- Desalination
- Removing salt from seawater to produce fresh water. At present, the mainstream methods use fossil fuels to evaporate seawater or pass it through a semipermeable membrane
- Coupled sea ice–ocean ecosystem model
- Simulation software for estimating how the environment of high-latitude seas with sea ice changes
ResearchResearch themes
The sea holds energy in its currents and waves, and its water and seabed contain useful resources. The lab proposes and evaluates new technologies for extracting these ocean resources and energy safely, while keeping the burden on the natural environment to a minimum.
*Illustrative imageSafely extracting deep-sea resources
The lab studies the safe design of the very long pipes used to extract deep-sea resources. It is also advancing research on flow assurance, to ensure that multiphase flow is transported soundly through pipes laid on the seabed.
*Illustrative imageGenerating electricity from ocean currents
Among the ways of harvesting natural energy from the sea, the lab focuses on absorbing energy from the flow of seawater to obtain electrical energy.
*Illustrative imageDesalination using solar heat
The lab aims to develop new desalination technology that mainly uses solar radiation. It is working on the design of and experiments with devices that collect solar heat efficiently, and on the scale of desalination use, such as comparing large-scale systems with few units against small-scale, distributed systems with many units.
*Illustrative imagePredicting the environmental impact of ocean development
This research predicts the spatial extent and changes over time of the effects that ocean development has on the physical and biological environment of the sea. In particular, the lab is developing a coupled sea ice–ocean ecosystem model for high-latitude seas with sea ice.
