What does a roustabout do on an oil rig?

Roustabout — Oil Rig: Role Overview

Entry-level deck crew responsible for safe cargo handling, housekeeping, basic maintenance support, and rigging assistance on offshore or onshore oil rigs. The roustabout keeps decks organized, equipment ready, and lifting operations flowing under supervision.

I. Core Responsibilities (Day-to-Day)

I.1 Cargo handling: prepare, sling, and secure loads; load/unload supply vessels; use taglines; apply banksman/signaller guidance under supervision.
I.2 Rigging assistance: select slings/shackles/spreaders to stated WLL; connect/disconnect lifting gear; control suspended loads; ensure tool boxes and baskets are properly netted and certified.
I.3 Bulk transfer support: make up/bleed down mud/brine/cement/chemical hoses; align valves; pressure-watch during transfers; leak checks; complete hose/iron housekeeping post-transfer.
I.4 Housekeeping and preservation: chip/needle-gun rust; pressure wash; prep and apply coatings; maintain non-slip; keep walkways, laydown areas, and storage organized.
I.5 General maintenance support: assist mechanics/electricians/rig welders with basic tasks (greasing, bolt-ups, gasket swaps, grinding, consumable runs, firewatch/hole watch during hot or confined work).
I.6 Waste and materials management: segregate waste streams; operate compactors/skips; stage and inventory deck cargo against manifests; steward consumables (slings, shackles, paint, rags).
I.7 Mooring and marine operations: handle mooring lines/fenders; standby during supply boat operations; follow radio commands; maintain safe exclusion zones.
I.8 Safety participation: attend toolbox talks/JSA; conduct line-of-fire checks and dropped-object inspections; exercise stop-work authority; participate in drills (fire, man-overboard, abandon).
I.9 Helideck/landing support (when trained/assigned): assist with passenger movement, baggage handling, and helideck housekeeping under HLO direction.
I.10 Seasonal/weather mitigation: ice/snow removal, gritting, water management; rig-up windscreens and barriers as directed.
I.11 Onshore rig yard tasks (when applicable): yard organization; rig-up/rig-down assistance; trucking interface for loads.

Toolchain Snapshot

Core: Slings, shackles, spreader bars, taglines, air tuggers, pressure washer, needle gun, gas detector.
Safety-critical: Harness + SRL, H₂S monitor, firewatch gear, spill response kit.
Digital (site-specific): e-PTW, CMMS terminal, handheld material scanners.

Rigging Math Used on Deck (estimated)

Roustabouts apply these under supervision; detailed calculations are typically performed/checked by certified riggers or crane operators.

III.M.1 Two-leg sling tension (angle from vertical = ?): Per-leg tension: LaTeX: \\( T = \\dfrac{W}{2\\cos\\theta} \\)
III.M.2 Angle factor (from horizontal = ß): LaTeX: \\( \\text{AF} = \\dfrac{1}{\\sin\\beta} \\), so per-leg tension \\( T = \\dfrac{W}{2}\\,\\text{AF} \\)
III.M.3 Check against sling WLL/SWL and hardware WLL; use lowest-rated component.
