Question to all OFW Tsikoteers especially to those working in the oilfield

[jeanpierre]

rig mechanic? your job description is maintenance, repair and installation of the following equipments:

- big diesel generators - caterpillar, emd, volvo, wartzilla, etc. from 500kw to 5000 kw, depende sa laki ng rig. you will have anywhere between 3 - 8 of these engines plus one or two emergency generators. meron din 2 camp generators pag land rig. (note: on production platforms the main electric generating plants will be gas turbines. ask mo sila ilan kw rating nun, but from what i know it's big enough to power a small city)
- small diesel engines - caterpillar, gm/detroit diesel, daimler benz, volvo, mitsubishi, toyota, etc. mostly on cranes, payloaders, forklifts.
- mud pumps - continental emsco, national, etc. these are big 3 cylinder reciprocating pumps with anywhere between 900 hp to 4000 hp pumping drilling mud at up to 10,000 psi. minimum of 2, some rigs have as many as 4.
- drawworks - think of it as a winch. a BIG winch. from 350 tons to 650 tons. some offshore rigs have 1000 tons (new deepwater double activity semis that can drill up to 35,000 ft depth at 7000 ft of water). land rigs will have 1000 hp, some offshore will have 4x1000 hp motors powering this.
- travelling block and crown block - think of it as 2 big pulleys, it is what carries all the weight of the drill pipes in the well. drawworks, crown block and travelling block will be like your small winch, block and tackle.
- top drive system - most modern rigs have this. it's like 1 big electric drill, between 1000hp to 3000 hp.
- rotary table - the dinosaur of the oil rig, it used to be the one that rotates the pipe but it has been replaced by the top drive. it is mostly used in land rigs. on offshore operations it is still used but only for making up the bha (bottom hole assembly, which includes the bit).
- hydraulic equipment - hydraulic power units, raise back systems, pipe racking systems, pipe handler (connected to the top drive used for making up and breaking out drill pipe), iron roughnecks (these are robots that automatically make up or break out pipe), cranes and other heavy equipment hydraulics, hydraulic elevators, etc. on BIG offshore rigs they have hydraulic engineers that take care of these.
- power tongs and pipe spinners, used for turning and tightening pipes and casings. spinners are either air or hydraulic powered, power tongs are hydraulic powered.
- pumps, lots and lots of pumps. centrifugal pumps, gear pumps, submersible pumps, vacuum pumps, air operated pumps, tripplex pumps, etc. these pumps move potable water, drill water, sea water for cooling, sea water for ballast, drilling mud, base oil (for making oil base mud), diesel fuel, helicopter fuel, lube oil, waste oil, bilge, etc.
- air compressors. most rigs have 3 or more compressors that have capacities of 350 cfm to 600 cfm. most will be powered by electric motors with 1 unit powered by a diesel engine either small or big. pag small then it is only an emergency compressor for starting the engines during a dead ship (or what is called a brown out in the philippines!) if it is big then it is both an emergency and main compressor.
- tuggers/winches - these are either pneumatic or hydraulic powered utility winches of capacities from 500 kilos to 10 tons. used for lifting or pulling loads in work areas.
- koomey unit - this is a hydraulic pump (air and electric pumps), hydraulic accumulators and reservoir used to provide hydraulic pressure to the blow out preventer (that big set of valves that prevent the well from exploding and killing you all). on land rigs and jack-up rigs (offshore rigs with legs that go all the way down to the sea floor, as oppose to rigs that float like drillships and semis) you are in-charge of this equipment.
- on semis and drill ships, high pressure air compressors (2500-3000 psi) for powering the compensator system. most rigs have 2.
- watermakers/desalination plants on offshore installations. these have capacities of 25 to 100 tons/day. most rigs have 2 of these.
- thruster systems - on self propelled and dynamically positioned offshore rigs. from 1000hp to 5000 hp. think of it as a ship propeller that is driven by big dc electric motors. most dp rigs will have between 6 to 8 of these. some have as many as 6 motors driving them. you are in charge of these, plus the gear box that go with it.
- anchor windlasses/winches - if it floats, it needs anchors. our rig has 8 of these. wire diameter is 2-7/8 inch x 6000 feet long. other rigs use chains. super ingay ang chain anchor lines, yanig naman betlog mo pag umaandar yung anchor winch!
- air dryers - you compress air, you need to remove the condensed water coz if you don't then all your air powered equipment will sudenly all decide not to work at the same time. also, air is used to move barite (dry clay in drilling linggo, used for making drilling mud) and cement (for cementing the casing in the well). if the air is wet then the mud engineer or the cementing engineer will be cursing you to death! the electrician will also be looking at you with a mean eye because you put wet air inside his panels (electric panels on the rig floor have positive pressure inside) and all that while you are trying to repair all those air powered equipment under your department!
- oil separators - you do not pump bilge to the sea, you need to separate the oil then pump out the oil-free water to the sea. then you put the waste oil in drums for processing/recycling.
- sewage treatment plant - the sh!t machine! yup, it's your job! this is something you do not want to break down, ever! it treats raw sewage, makes it environmentally friendly (read, all bacteria and virus must die!)

- and last but not the least, all the paper work that come with it. that means planning, recording, budgetting, etc etc etc!


did i scare you? naaaah! it's all bolts and nuts! nothing a BIG hammer can't fix ehehehehehe!

:bwahaha: Dami naman yebo. Nakalimutan mo mentioned safety equipments like lifeboats. Kainis pag abandon rig drill kasi kailangan pumasok designated crew sa kanya kanyang lifeboat parang sardinas

:bwahaha: Dami naman yebo. Nakalimutan mo mentioned safety equipments like lifeboats. Kainis pag abandon rig drill kasi kailangan pumasok designated crew sa kanya kanyang lifeboat parang sardinas

may kasama ba pag pasok sa lifeboat? baka ibang lahi pa kasama doon na di marunong maligo ang sakit sa ilong non ..hehehe

Yan ang masakit minsan. Kalimutan mo muna himinga pagnasa loob na kayo :bwahaha:

[BoEinG_747]

hahaha ,,ang sakit nga non,,
minsan kumakapit pa naman ang amoy ng mga iyan sa shirt mo

naalala ko may kasama ako ibang lahi binisita ako sa room ko ,
eh di pinaupo ko ,ilang minutes lang nakaupo nangamoy na ang room ko
at kumapit na amoy sa chair ko

bigla tuloy ako nag carpet shampoo at vacuum ng room

ano kaya bagsak sa ECE? me too gusto ko rin sa OILFILED may experience pero semicon non related to OILS

IMO, kung may chance ka lang sa Schlumberger wireline maganda/ I don't remember kung anong year yon when they recruited ECE and electrical guys sa pinas. Medyo mahirap daw screening but if you make it, best ang training nila at di ka mahihirapan transfer sa ibang company later. Kilala Schlumberger worldwide. Infact when I applied for the US visa to attend a seminar sa states, dala ko papers with their heading/logo lang. Wala pa yata 5 minutes kausap ang consul, approve na visa ko.

[BoEinG_747]

ano ba normally job ng entry level sa oilfield or gas refinery?

[yebo]

radiozone,

kakatapos lang ng recruitment ng schlumberger wireline sa pinas last january. di ka nagbabasa ng classified ads ano! 3 times lumabas ang ad nila last december and january. kasama sa batch na yun pinsan ko, nasa qatar na siya ngayon. entry level salary na binigay sa kanya (base support personnel siya, mech engineer) ay medyo maliit, qatar R 5300 plus QR 2900 allowance. kaso lang dahil base support siya e 1 year on less weekends/1 month off sked nya. saka na lang siya lilipat sa offshore pag naka-dama na. balita ko sa kanya yung mga EE and ECE ay offshore assigment so training sked ay 3 months on/1month off yata.

boeing,

as in any work, trainee ang pasok mo. like me start ako as trainee. naligo sa grasa, langis, putik...kakalimutan mo na engineer ka pag nasa training ka pa lang at puti lang ng mata mo ang hindi madumi.

[yebo]

speaking of mabantot! meron ako kasama dito sa room ko ngayon australiano na trainee subsea. panay ang utot! 2 nights ago ba naman e aga nya natulog tapos umuutot, labas ako ng room. pag balik ko baho pa din, labas ulit ako. di ko ginising at di naman nya siguro kasalanan kung umutot siya habang tulog di ba? pero pangatlong balik ko may dala na ko air freshener at electric fan. open ko door ng room, on ang fan. nagising ang ogags ask nya bakit daw. sabi ko panay utot nya, pasalamat siya di ko siya tinadyakan. nagreklamo pa si loko at di daw siya makatulog! palipatin ko nga ng room ang ogag! 10 pm pinaalis ko sa room hakot siya ng gamit nya hahahaha!

[jeanpierre]

Sipag, tyaga at pasensya lang talaga pag nasa training ka pa lang. Tama si yebo, kalimutan mo na engineer ka. If you make it naman, sulit sa sweldo na makukuha mo. Saka isipin mo na rin ang schedule mo, pamilyado ka di masyadong mahirap. Wala na yata gagandang trabaho pa dito.
