Environmental challenges related to hydrocarbon-based energy sources as well as resource constraints are the driving forces behind the R&D focus of StatoilHydro. In this presentation we will discuss availability of hydrocarbon energy sources and global energy demand. We will show how this motivates the research focus of StatoilHydro.

The mixing of temperature and pollutants in the ocean can be studied by examining how pairs of particles, deployed together, separate in time and space. Here we consider a recent field experiment in which 120 satellite-tracked surface drifters were deployed in pairs and triplets off the Norwegian coast. We discuss the observed dispersion, and how this can be rationalized within the framework of the theory of two-dimensional turbulence.

Recent efforts to investigate a possible increased lifetime of old platforms have brought attention to some challenging hydrodynamic problems. Due to higher extreme waves and subsidence of seabed some of these platforms have become vulnerable to wave crests hitting the deck of the platform. Higher estimates of extreme wave crests may be due to better understanding of non-linear wave effects as well as including the uncertainty related to possible climate change effects. Due to complexity of deck geometry, CFD has been found necessary to predict wave impact loads. Numerical procedures to estimate extreme wave crests, obtain corresponding fluid particle kinematics and calculate impact loads will be presented.

The word seismology is often associated with earthquakes. However, the tightly related term ``seismic'' comprises a valuable technology used extensively by the oil and gas industry in its exploration, development, and reservoir management operations. This talk will explain how marine seismic operations are carried out, and highlight some technological challenges that are faced. Special attention will be given to a factors like wave motion and turbulence, that add complexities to the operational environment. Such factors are challenging to handle from both a fluid dynamical and a signal-processing perspective.
