BOP stack (surface)

Surface blowout preventer stack on a casing head: single ram, drilling spool, double ram and annular preventer, with bolted bonnets, operating cylinders and ram locks along X. The drilling spool carries the choke (+Z) and kill (-Z) lines, each with a manual gate and a hydraulic HCR valve and a crossover to a B16.5 flange. Hydraulic hoses run from a junction plate to every function, inside a yellow handling frame with padeyes. Body proportions are typical for a 13-5/8" 10k stack and scale with bore and pressure.

Installation

Copies wellhead/bop-stack.tsx and the shared lib/ into src/components/deck-twin/. Needs three, @react-three/fiber and @react-three/drei. See installation for the manual route.

Usage

import { Canvas } from '@react-three/fiber'
import { OrbitControls } from '@react-three/drei'
import { Stage } from './components/deck-twin/lib/stage'
import { BopStack } from './components/deck-twin/wellhead/bop-stack'

export default function Scene() {
  return (
    <Canvas shadows camera={{ position: [8, 5, 9], fov: 35 }}>
      <Stage>
        <BopStack />
      </Stage>
      <OrbitControls makeDefault />
    </Canvas>
  )
}

Props

P&ID

A vertical stack of boxes: the annular preventer on top (tapered or rounded), ram preventers (rectangles with rams drawn from both sides, labelled pipe / blind / shear), and a drilling spool with the choke and kill lines and their valves leaving each side.

tag BOPISO 10628-2 / PIP PIC001 valves; API 6A / API RP 14C wellhead conventions; API 16A / API 53 BOP schematic

Rams drawn as boxes with side rams distinguish a BOP from a christmas tree (bow-tie valves). Only on drilling or well-control schematics, not process P&IDs.

For agents

Machine-readable entry with props, ranges, defaults and ports:

Or fetch /r/bop-stack.json, or copy a ready-made instruction:

Add the Deck Twin "BOP stack (surface)" component to this project. Run `npx -y https://decktwin.com/cli/deck-twin-0.2.2.tgz add bop-stack` (it copies the file and the shared lib into src/components/deck-twin/), then `npx -y https://decktwin.com/cli/deck-twin-0.2.2.tgz info bop-stack` for its props, ranges and ports. Render <BopStack /> inside a React Three Fiber <Canvas shadows>, wrapped in <Stage> from src/components/deck-twin/lib/stage. Set props from my data (metres, NPS in inches, ASME class) and leave the rest at defaults. Install three, @react-three/fiber, @react-three/drei and @types/three if they're missing.
