场景 1：船体结构焊补与校正

Surveyor: Let’s check the hull plate patching on Section A-3. The welding seam here is uneven—did you perform a water test?
（我们看看 A-3 区域的船壳板焊补。这里的焊缝不平整，做过冲水试验吗？）

QC: Yes, we did a hose testing yesterday, and there was no leakage. The unevenness is within 2mm, which is acceptable per the yard’s standard.
（做了，昨天做了冲水试验，没漏水。不平整误差在 2 毫米内，符合船厂标准。）

Surveyor: The yard’s standard isn’t enough—it must meet Class Rule 5.7, which requires a maximum 1mm deviation for critical areas. Grind it smooth and retest.
（船厂标准不够，必须符合船级社 5.7 条规范，关键区域偏差不能超过 1 毫米。磨平后重新测试。）

QC: Understood. What about the plate with single curvature on the bow? We fair in plate as per the drawing, but there’s a slight twist.
（明白。船头的单曲率板呢？我们按图纸原地校正了，但有点轻微扭曲。）

Surveyor: Measure the twist—if it’s over 3mm/m, it needs off fair. The anchor chain locker’s steel work must also be checked for weld penetration.
（测一下扭曲度，如果超过 3 毫米 / 米，就得拆装校正。锚链舱的钢质工程也要检查焊透情况。）

场景 2：机舱管系安装与压力试验

Surveyor: The pipe work in the engine room—did you replace all gaskets as required? Last time, the reducing valve leaked due to a worn gasket.
（机舱管系 —— 按要求换所有垫片了吗？上次减压阀就是因为垫片老化漏了。）

QC: Yes, all gaskets are new, including those for the regulating valve. We’ve also done a hydraulic pressure test at 1.5 times working pressure for 30 minutes.
（换了，所有垫片都是新的，包括调节阀的。我们还做了 1.5 倍工作压力的水压试验，保压 30 分钟。）

Surveyor: Show me the test records. Also, the pipe to be blowed free for the fuel oil system—was it done with dry air or nitrogen?
（给我看看试验记录。另外，燃油系统的吹通管子，是用干燥空气还是氮气吹的？）

QC: We used dry air, but the pressure was controlled below 0.6MPa to avoid damaging the strainer plate.
（用的干燥空气，但压力控制在 0.6 兆帕以下，避免损坏滤板。）

Surveyor: Nitrogen is required for fuel pipes to prevent oil residue ignition. Do it again with nitrogen and record the pressure curve.
（燃油管必须用氮气，防止油 residue 被点燃。重新用氮气吹，并记录压力曲线。）

场景 3：轴系安装与尾轴密封检查

Surveyor: The tailshaft reinstallation—did you check the brass sleeve for cracks? Magnetic test results?
（尾轴装复 —— 检查铜轴套有没有裂纹吗？磁性探伤结果呢？）

QC: The magnetic test passed, no cracks found. The shaft journal and shell clearance is 0.15mm, which is within the design range.
（探伤过了，没裂纹。轴颈和轴瓦间隙 0.15 毫米，在设计范围内。）

Surveyor: What about the stern tube sealing? The rope guard is installed, but the packing groove must be filled with new packing—show me the material certificate.
（尾轴管密封呢？防绳罩装了，但填料槽必须填新填料 —— 给我看看材料证书。）

QC: Here’s the certificate for the graphite packing. We also measured the thrust block clearance—0.2mm, which is within the allowable 0.3mm.
（这是石墨填料的证书。我们还测了推力块间隙 ——0.2 毫米，在允许的 0.3 毫米以内。）

场景 4：船体除锈与涂装厚度验收

Surveyor: The grit blasting on the double tank—your report says Sa2.5, but I found some residual rust in the corner welds.
（双层底舱的冲砂 —— 报告写的是 Sa2.5 级，但我在角焊缝处发现残留锈迹。）

QC: Those are tight corners—we did manual scraping and chipping after grit blasting. The micron gauge shows 280μm for the top coat, which exceeds the required 250μm.
（那些是死角，冲砂后我们手工铲刷过了。测厚仪显示面漆 280 微米，超过要求的 250 微米。）

Surveyor: Thickness is good, but rust residue will cause premature coating failure. Use a wire brush to clean those areas and apply a touch-up coat.
（厚度没问题，但残留锈迹会导致涂层过早失效。用钢丝刷清理后补漆。）

QC: What about the bitumen coating on the hull bottom? We applied two coats as specified.
（船底的沥青涂层呢？我们按要求涂了两道。）

Surveyor: The second coat was applied before the first dried completely—there are bubbles. Scrape them off, reapply, and let it cure for 48 hours before inspection.
（第二道是在第一道没干透时涂的，有气泡。刮掉重涂，固化 48 小时后再检查。）

场景 5：辅机安装与安全装置检查

Surveyor: The auxiliary boiler’s safety valve—did you test its lifting pressure? It should open at 1.1 times the working pressure.
（辅锅炉的安全阀 —— 测试起跳压力了吗？应该在 1.1 倍工作压力时起跳。）

QC: Yes, we tested it three times, and the lifting pressure was 0.88MPa, which is correct (working pressure 0.8MPa). The fire surface insulation is also intact.
（测了三次，起跳压力 0.88 兆帕，对的（工作压力 0.8 兆帕）。火面的绝缘层也完好。）

Surveyor: Check the L.O cooler’s sea water side for marine growth—last drydock, it was blocked, causing overheating.
（检查滑油冷却器的海水腔有没有海生物 —— 上次坞修就堵了，导致过热。）

QC: We cleaned it with high-pressure water and did a flow test—no blockage. The turbo charger’s insulation was replaced too, as it was damaged.
（我们用高压水清洗过，还做了流量测试 —— 没堵。增压器的绝缘层也换了，之前坏了。）

Surveyor: Good. The next check will be the main engine’s sweeping port—ensure it’s free of carbon buildup before the load test.
（好。下次检查主机扫气口 —— 负荷试验前确保没有积碳。）
