English term or phrase: derrick

Definition from Petex:
a large load-bearing structure, usually of bolted construction. In drilling, the standard derrick has four legs standing at the corners of the substructure and reaching to the crown block. The substructure is an assembly of heavy beams used to elevate the derrick and provide space to install blowout preventers, casingheads, and so forth.

Example sentence(s):

A worn bit can be detected by the noise on the derrick floor that the rotating drill pipe makes and by a decrease in rate of drill penetration. Foster Learning Inc.
The downward force on the drill bit is the result of the weight of the overhead drill stem (steel pipe, pipe joints called collars) and drilling equipment on the derrick all of which can amount to thousands of pounds. Tidal Petroleum
The worker in the photo below is known as a derrick man. He works up at the top of the oil rig and stacks the "stands" or combined joints of pipe back against the derrick. energyindustryphotos.com

boretårn

Definition from Den Store Danske:
http://www.denstoredanske.dk/It,_teknik_og_naturvidenskab/Te...

boretårn, stålgitterkonstruktion til ophængning af bor og rotationsmekanisme. Anvendes til dybere boringer på landjorden og til havs med det formål at eftersøge og indvinde vand og kulbrinter. Boretårne anvendes ligeledes ved optagning af jord-, is- og bjergartsprøver. Se boreplatform.

Example sentence(s):

En olieboring indledes med opsætning af et boretårn. Heri findes en motor, som kan dreje et lodret stillet borerør af stål - Den Danske Ordbog
En olieboring indledes med opsætning af et boretårn. Heri findes en motor, som kan dreje et lodret stillet borerør af stål. I den nederste del af borerøret er monteret et specielt konstrueret borehoved, som kan gnave sig gennem hårdt materiale. Belastning og rotation af borerøret vil langsomt drive dette ned gennem jordskorpen. Efterhånden som røret når længere ned, må det hele tiden forlænges med nye rørstykker. Resultatet af en boring vurderes ved regelmæssigt at udtage boreprøver i forskellig dybde af jordskorpen. Hver gang det sker, er det nødvendigt igen at trække samtlige rør op af borehullet og starte forfra! Udvinding af olie og naturgas foregår i princippet gennem - Olie - et dansk råstof, Gunnar Cederber
Så er det slut med vartegnet i Kvols. Boretårnet er nedtaget og boringen efter varmt vand er midlertidig stoppet. Om det geotermiske projekt nogensinde bliver åbnet igen, er stadig usikkert. - Fjends Folkeblad
