Vessel

Like the Petroleum Act, the Working Environment Act will apply to facilities in the petroleum activities. The term facility is the same as is used in the Petroleum Act, cf. the definition in Section 1-6, litera d of the Petroleum Act. The Working Environment Act has a different, narrower application for vessels than the Petroleum Act, but in the determination of what constitutes a facility and what constitutes a vessel, the same criteria as follow from the petroleum legislation form the basis. Reference is here made to the delimitation in the Petroleum Act in connection with Section 1-4 cf. Section 1-6 litera c, which further limits what vessels can be considered supply and standby vessels, cf. Odelsting Proposition No. 43 (1995-1996), pages 27 and 28. The term includes, in addition to vessels that transport personnel and equipment, crane barges and other service vessels, vessels used to carry out manned underwater operations, pipe-laying vessels, vessels that carry out seismic surveys, etc. On the other hand, e.g. mobile drilling facilities, drilling or production vessels, flotels, etc. will clearly be covered by the term facility. As follows from the second subsection, however, certain restrictions have been set in the actual scope in relation to the Petroleum Act, which entails that the Working Environment Act will have a somewhat more limited application as regards the vessel function.

"Waste", as applied to oil, includes underground waste; inefficient, excessive, or improper use or dissipation of reservoir energy, including gas energy and water drive; surface waste; open-pit storage; and waste incident to the production of oil in excess of the producer's aboveground storage facilities and lease and contractual requirements, but excluding storage, other than open-pit storage, reasonably necessary for building up or maintaining crude stocks and products thereof for consumption, use, and sale.

  3. 
Abuse of the correlative rights of any owner in a pool due to nonuniform, disproportionate, unratable, or excessive withdrawals of oil or gas therefrom, causing reasonably avoidable drainage between tracts of land or resulting in one or more producers or owners in such pool producing more than his equitable share of the oil or gas from such pool.
