Obviously this objective is not unique to North Sea production platforms. Barring certain peculiar circumstances it is always desirable, within economic limits, to maximize the recovered barrels of stock tank oil per unit volume of well stream production. This has the effect of increasing the ratio of barrels of stock tank oil to barrels of reservoir oil, which is defined as the formation volume factor.

Snohvit will also be the first major development on the Norwegian continental shelf without support from a floating unit. A sub sea production system on the seabed will feed the land-based LNG plant via a 0.68 m ID, 160 km two-phase pipeline. In addition two chemical lines, an umbilical and a separate pipeline for the transport of carbon dioxide will be included. The unprocessed well stream from Snohvit is separated and the gas is treated and cooled to a temperature below the boiling point (-162 °C) to form LNG. This operation employs a large cold box (40 m high and a footprint of 15x17 meter).

Promotion of the enrichment of iodine content of certain drinks and foods, with the aid of health education such products are marked with a special logo. Health education is also focused on increased consumption of saltwater fish and other sea products. Consumption of these products has traditionally been low in the Czech Republic. It has been possible to increase this consumption, for example, in the form of meals provided to schoolchildren. 

On the other hand, simple equipment is less sensitive to extremes of location and environment. The main aspect that affects simple equipment is its full-load rating for low and high ambient temperatures. The details of the construction will be almost unaffected. Simple equipment used in high ambient temperatures will tend to be physically larger and heavier. A motor of a given shaft output rating may have a larger standard frame size when used in a desert than one used on a North Sea production platform. 

The economic consequences of the incident have been felt across the region a drop in the income from tourism, loss of income from fishing, and a ban on the trade of sea products, including oysters and crabs, have added to the discomfort of local populations. 

Materials selection for a large sub-sea production system is illustrated by the following example from a field in the North Sea [10.11] for the production tubing and the well equipment (whieh are not to be welded) a 13% Cr steel was seleeted, and in the Xmas tree (valve tree) a martensitie stainless steel of the type ASTM A 182 F6NM (13%) Cr, max l%o Si). The manifold module, whieh is a welded pipe system, was made of a ferritie-austenitie stainless steel with the eomposition 22Cr5Ni3Mo, which also was selected for pipelines for supply of hydraulie oil and methanol (used for preventing hydrate formation) to die sub-sea stations. The well flame and gas pipeline were made of a non-stainless steel.

The system shown in Fig. 2.7 produces over 2000 N m3/h of nitrogen for inerting equipment on a North Sea production platform. Such systems must be constructed for operation under severe environment conditions, particularly ambient temperature extremes, ice loading, and sea-water corrosion. 

Carotenoids have received much attention because of their various functions. They are natural pigments synthesized by plants and some microorganisms. Carotenoids exhibit yellow, orange, and red colors but when they are bound to proteins, they acquire green, purple, or blue colors. They are found in a large number of natural products, such as fruits, vegetables, and sea products.

The system model consists of two elements (1) a D-SPICE model of on-shore facilities and sub-sea utilities and (2) an OLGA 2000 model of the sub-sea production wells and pipelines. These two models are fully integrated and share a common, D-SPICE, user interface.
