Emergency Shutdown Interlock Test — Gas Processing Plant
Alright team, today we're testing the Emergency Shutdown System — the ESD. This is SIL 2 per the safety requirements specification. We have 12 SIFs — Safety Instrumented Functions — to test. Each one must trip the correct final elements within the specified response time. Fiona, this is a witnessed test — you'll sign off on each SIF as we go.
好了团队，今天测试紧急停机系统——ESD。按安全要求规格书这是 SIL 2。我们有12个SIF——安全仪表功能——要测试。每个都必须在规定 响应时间内触发正确的最终元件。Fiona，这是见证测试——你逐项SIF 签字确认。
Let's start with SIF-01: High pressure in the inlet separator trips the inlet ESD valve XV-101 and the fuel gas ESD valve XV-301. Cause: pressure transmitter PT-101A/B (2oo3 voting) exceeds 85 bar. Effect: close XV-101 and XV-301 within 3 seconds, and initiate a blowdown of the separator.
从SIF-01开始：进口分离器高压触发进口ESD阀XV-101和燃料气ESD 阀XV-301。原因：压力变送器PT-101A/B（3取2表决）超过85 bar。 后果：3秒内关闭XV-101和XV-301，并对分离器进行放空。
PT-101A and PT-101B are ready. I'll inject a simulated pressure signal at the transmitters — first PT-101A to 86 bar. This should NOT trip — we need 2 out of 3 voting.
PT-101A和PT-101B已就绪。我在变送器处注入模拟压力信号——首先 PT-101A到86 bar。不应触发——我们需要3取2表决。
(injects signal) ESD logic solver shows 1 out of 3 channels in trip state. System status: "1oo3 Trip — No Action." Correct — 2oo3 voting means one channel tripping doesn't activate the SIF. Now injecting PT-101B to 86 bar as well...
（注入信号）ESD逻辑解算器显示3通道中1通道触发。系统状态： "1oo3 Trip—No Action"。正确——3取2表决意味一个通道触发不激活SIF。 现在PT-101B也注入86 bar……
ESD status: "2oo3 Trip — ACTION." XV-101 closing... fully closed in 2.1 seconds. XV-301 closing... fully closed in 1.8 seconds. Both within the 3-second requirement. SIF-01 response time: 2.1 seconds. PASS.
ESD状态："3取2触发—执行"。XV-101关闭中……2.1秒全关。XV-301 关闭中……1.8秒全关。都在3秒要求内。SIF-01响应时间：2.1秒。通过。
SIF-01 witnessed and accepted. I note the response times are well within the specification — good margin. Let's continue with SIF-02.
SIF-01见证并接受。我注意到响应时间远在规格书要求内——裕量很大。 继续SIF-02。
Boiler Sequence Control — Cold Startup Commissioning
Chen, we're doing the first cold startup of Boiler B-101 under DCS sequence control. All pre-commissioning is done — loop checks complete, interlocks tested. Now we're going to run the full startup sequence from the DCS: purge → pilot ignition → main flame → ramp to minimum load. Igor, you'll monitor the boiler from the local panel. Let's walk through the permissives first.
Chen，我们在做B-101锅炉DCS顺序控制的首次冷态启动。预调试全部 完成——回路检查完成、联锁已测试。现在跑DCS全启动序列：吹扫→点火 枪点火→主火焰→升至最低负荷。Igor，你在就地盘监控锅炉。先过一遍 允许条件。
Calling up the permissive screen. Boiler start permissives: feed water pump running — CHECK. Drum level above low-low — CHECK. Fuel gas pressure normal — CHECK. Combustion air fan running — CHECK. No active trips — CHECK. All permissives green. The sequence start button is enabled.
调出允许条件画面。锅炉启动允许条件：给水泵运行—满足。汽包水位 高于低低限—满足。燃料气压力正常—满足。助燃风机运行—满足。无活跃 跳闸—满足。所有允许条件绿灯。顺序启动按钮已使能。
OK, initiating the startup sequence. Step 1: Purge. The DCS should open the FD fan damper to 100%, run the purge for 60 seconds at minimum 5 air changes. Watch the sequence display.
好，启动顺序。步骤1：吹扫。DCS应把送风机风门开到100%、以至少 5次换气量运行吹扫60秒。看顺序显示。
Purge started. FD fan damper at 100%. Air flow: 12,500 Nm³/h — that's 6.2 air changes per minute. Timer counting down: 58, 57, 56... purge complete. Step 2: Pilot ignition. Ignition transformer energizing, pilot gas valve opening... Pilot flame detected — flame scanner signal strong.
吹扫开始。送风机风门100%。空气流量12,500 Nm³/h——相当于每分钟 6.2次换气。计时器倒计时：58、57、56……吹扫完成。步骤2：点火枪点火。 点火变压器通电、点火枪气阀开启……检测到点火火焰——火焰扫描信号 强。
Step 3: Main gas valves. The DCS will open the main gas safety shutoff valves in sequence — first the vent valve closes, then SSV-1 opens, pressure proves for 5 seconds, then SSV-2 opens. Igor, watch the flame at the sight glass.
步骤3：主燃气阀。DCS将按顺序开启主燃气安全切断阀——首先放空阀 关闭、然后SSV-1开启、压力验证5秒、然后SSV-2开启。Igor，通过观察 孔看火焰。
Main flame established! Burner is stable, flame is blue with a slight yellow tip — good combustion. The boiler is firing at 15% rate. DCS is now ramping up to minimum continuous load — 30%.
主火焰建立！燃烧器稳定、火焰蓝带微黄——燃烧好。锅炉负荷15%。 DCS正在升至最低连续负荷——30%。
After a successful startup, no alarms. Boiler B-101 is online in automatic mode. Lars, I'm documenting this in the commissioning log. This is a clean startup — zero sequence steps skipped, zero trips. Good engineering.
成功启动、无报警。B-101锅炉自动模式在线。Lars，我记录在调试 日志里。这是一次零跳步、零跳闸的洁净启动。好的工程设计。
