Gas hydrates are found primarily in the ocean in deep sea continental margins and beneath the permafrost in arctic regions.Most of the marine gas hydrates are found in clay rich sediments and they need low temperatures and high pressures to form.Gas hydrate can emerge as a potential energy resource.It can be a potential hazard to offshore hydrocarbon drilling and production operations too.

The management of risks associated to geohazards(geohazard risks)is a critical part of offshore energy development projects across their full life cycle,from the access stage through to the abandonmen
As a result of global climate change and human interference,extreme coastal and marine geological hazards,occur frequently and become gradually more complicated and intensive,which will cause signific
This presentation will discuss the role of diagnostic integrated geoscience(DIG)in marine site characterisation for engineering assessments.The process and life cycle of DIG will be dicussed first,fol
In the past,diving was overlooked,owing to the cultural misperception within the scientific community that it is merely a recreational tool that adds some value to shallow water sciences.In reality,pl
Identification of soil stratification is vital to offshore geotechnical structural design and construction where the soil layer,soil type and properties are necessary inputs.Although methods are avail
In the submarine environments,the pipeline-seabed interaction system is extremely complex,which primarily involves two competitive physical processes under the hydodynamic loading for the partially-bu
For any type of offshore large floating structures,such as oil and gas platforms,seadromes,artificial islands and storage and transit bases,an effective,reliable and economic positioning technique is
Piled foundations are widely used to underpin both onshore and offshore structures,such as offshore oil platforms,cross-river/strait bridges,wind turbines,with the driven piles being the major type Ho
Granular materials in the marine environment are subject to complex loadings at various strain rates and magnitudes which can be dynamic and induced by,e.g.seismic waves.In order to understand the res
Due to the building of a very big bridge(Asparuhov Bridge)through the bay of the city of Varna in Bulgaria,very detailed and big investigations of the marine deposits have been made.The engineering ge
