Toolpusher: The highest position at the drilling location, responsible for every crew. A toolpusher may stay on location for a few days or weeks at a time during operations, whereas individual drilling crews work only eight- or 12-hour shifts or "tours" (pronounced as "towers"). Driller: The head of an individual crew, responsible for controlling a rig's machinery during drilling, as well as most other rig operations. Derrickhand (derrick-man): Responsible for the drilling mud, the mud pits where drilling fluids are circulated around the system, and the mud pumps, as well as being the hand up in the derrick manipulating stands into and out of the fingers during tripping operations. Acting as a lead for the driller who is mostly restricted to the rig floor. Motorman (motorhand): Responsible for maintenance of various engines, water pumps, water lines, steam lines, boilers and various other machinery incorporated into the rig on a daily basis. Also responsible for movement of equipment on site. On a four-man drilling crew the motorman is also the chainhand. Boilerman: Though this position is now obsolete, before the mid-20th century, when most rigs were steam-powered, the boilerman was responsible for the boilers. The boilerman also functioned as the laundryman, steam-cleaning the last crew's greasy work clothes in the "blow barrel" and then hanging them up to dry in the warm air near the boilers. Leadhand/Floorhand ("worm"): Usually the lowest member of the drilling crew, those in this position are often nicknamed "worm", because this hand has the dirtiest and most physically demanding position. The floorhand works primarily on the rig floor where he is the one actually operating the tongs, iron roughneck, tugger, and catwalk, and doing pretty much any other job which is asked of him. Chainhand (Floorhand): This position is given to a floorhand that can also throw chain, but as of 2013 in the oilfields is pretty much just another floorhand that watches out for the worm and does not get as filthy. Roustabout (leasehand): On bigger rigs and offshore rigs, a roustabout does most of the painting and cleaning so roughnecks can take care of other work. Ginsel: The worm's helper. This is also derogatory insult among roughnecks. Also called the fifth hand.
In Canada on land-based rigs, the term roughneck refers to the floorhand.
As the job title implies, the primary responsibilities of the oil rig motorhand (or motorman) are to keep the engines that power the drilling equipment and some of the other rig equipment working smoothly. For example, engines are used to lift drilling pipe, turn the rotary table that turns the drill bit, and for mixing and circulating drilling fluid like mud.
Equipment varies somewhat from rig to rig, but generally speaking a rig has a combination of diesel and electric engines. Motorhands spend most of their time on the engines but also:
train roustabouts and roughnecks assist other oil rig crew as necessary maintain and lubricate machinery to keep it running efficiently assess tongs that help connect and disconnect drill pipe and spinning chain work with the rig's boilers regularly test equipment for operability and safety order tools and replacement parts
pump man (เป็นตำแหน่งงานบนเรือ แต่เราเอามาใช้ในความหมายเดียวกันเดี๊ยะครับ)
//en.wikipedia.org/wiki/Pumpman
A pumpman is an unlicensed member of the engineering department of a merchant ship.[1] Pumpmen are found almost exclusively on tankers, and on oil tankers in particular.[2] Variations on the title can include chief pumpman, QMED/pumpman, and second pumpman.[3] A pumpman performs all work necessary for the safe and proper operation of the liquid cargo transfer system.[1] This includes but is not limited to: liquid cargo transfer pumps, liquid cargo stripping pumps, liquid cargo coalesces and separators, strainers, filters, associated piping, valves, fittings, and deck machinery directly related to the transfer of liquid cargo.
