The offshore drilling operations generate huge volume of drill cuttings. Rig site transfer of cuttings can be a challenge both if pneumatic conveyors or screw conveyors are used. Especially, wet powder is a challenge since the particles become too st

Investigations of the morphology of metal oxide scales formed at high temperatures in oxidative environments are usually undertaken after exposure of the samples is completed. In this study, an environmental scanning electron microscope (ESEM) was us

The oxidation of iron at elevated temperature in pure oxygen and water vapor and the decomposition of wustite were studied in situ with environmental scanning-electron microscopy (ESEM). Depending on the type of gas atmosphere, iron formed either a p

High temperature corrosion of pure iron and nickel has been studied in situ with an environmental scanning electron microscope (ESEM). Metal samples were exposed to methanol vapour and hydrogen–carbon monoxide gas mixtures at temperatures from 773

Ir-Pd alloys were formed on Pd(110) by evaporation of Ir and subsequent heating in vacuo. Ir overlayers were stable up to 600 K. At higher temperatures Pd diffusion to the surface occurred, which resulted in a Pd-dominated surface over a range of Ir

Periodically on semi-submersibles, it is required to perform planned and occasionally unplanned disconnects of the marine riser from the subsea BOP stack. The reasons are diverse but always result in a change out of fluids in the riser. Typical circu

The new OSPAR regulation (OSPAR 2000/3) on drill cuttings is due to be effective by January 2005 at the Norwegian continental shelf. Drilling operations planned to be performed from to date and onwards therefore have to take into account that the for

The adsorptive and reactive behaviour of TiO2, SrTiO3 and SrO towards methanol have been investigated using temperature-programmed desorption and XPS. TiO2 was found to be reduced during the adsorption/desorption process and showed predominantly CH4
