2017:00007 A - SubSea Dispersant lnjection (SSDI)- a "state of the art" and the need for further documentations

http://www.sintef.no/en/publications/publication/?pubid=CRIStin+1477952

The aim of this pre-project has been to give a "State-of the art" and describe the R&D challenges and documentation needed in order to perform robust NEBA (Net Environmental Benefit Analysis) where SubSea Dispersant Injection (SSDI) is included as an acceptable countermeasure option. In spill sc...

Potential impacts of mine tailing plumes on pelagic filter-feeders

http://www.sintef.no/en/publications/publication/?pubid=CRIStin+1363483

Deposition of mine tailings in fjords along the Norwegian coast is known to have ecological implications for benthic fauna, but little information is available on the potential impacts on pelagic organisms. Depending on local hydrology, deposition of tailings can result in plumes where the particle ...

Real-time Decision Support for Drilling Operations in Sensitive Areas

http://www.sintef.no/en/publications/publication/?pubid=CRIStin+1349328

Drilling operations produce particulate drilling matter which is often discharged on, or close to, the sea floor. Properties like grain size and composition of the discharged matter, and ocean currents, determine where and to what degree this matter will be spread on the sea floor and in the water c...

Modeling filtration of dispersed crude oil droplets by the copepod Calanus finmarchicus

http://www.sintef.no/en/publications/publication/?pubid=CRIStin+1221023

Oil droplets may form and disperse in the water column after an accidental spill of crude oil or petroleum products at sea. Micro-sized oil droplets may be available for filter feeding organisms, such as the copepod Calanus finmarchicus, which has been shown to filter oil droplets. In the present pa...
