Reports on offshore companies' efforts to remediate the damage done by drill cuttings at the bottom of the North Sea to the natural environment. Potential use of bioremediation to speed up the natural degradation of the cuttings on the seabed; In-situ solution being pursued by the Environmental...
In this manner, the lobes will sweep over the rig floor once each revolution of the Kelly/drill string assembly. An example of a one-lobe antenna is the well-known dish-type antenna; a simple horizontal centerfed dipole has two lobes. The block diagram of the receiver is shown in FIG...
Andreassen thinks there will be more large blow-outs in the ocean floor south of Svalbard, as the seabed becomes warmer and gas-hydrate reservoirs thaw.Andreassen says there is probably even more methane gas locked in the seabed around Greenland and in the Arctic Ocean than is found in the...
shoppers are required to spend a heckuva lot more than your typical Swede to keep all that floor space in profits, paying their light and heating bills, and employees, etc. Suggesting that they're probably buying a lot of crap they don't need; and heaven help the merchandisers when they...
designed with enough output to heat cold water very quickly, if the water is allready quite hot the flow rate through the heat exchanger may not be enough to prevent overheating (worst case the water boils and blows off via the emergency release valve on the unit onto the floor or ...
The most experienced cyclist belongs at the back of the group in the sweep position. Ideally this person has tools and the skills to use them, an awareness of first aid, and preparation to deal with any problem that might come up. Unless RonToppiis behind me, this is my preferred positio...
morning after a snowfall I sweep the panels with a broom even though they might melt out eventually. the days are very short, it's even more important to get every available watt. them on the roof would mean using probably twice as many panels. manual tracker produces 30-40% more...
In the operation of subsea pipelines, the waxy oil enters at reservoir temperature (65– 85∘C) and cools along its way to the platform, due to the low temperature of the sea floor (≃4∘in deep water conditions). Whenever feasible, the operation is designed to ensure that the oil...
42. In this example, edge effects are minimized because the sweep is tapered at the beginning and end of the sweep while also maintaining the required bandwidth by using a constant amplitude. In this case, the frequency range is larger than the transducer bandwidth such that the excitation ...
