Failure / Improvement Log

This page captures recurring field issues, technical weaknesses, operational pain points, and the corresponding improvement direction. Its purpose is to convert ten years of scattered experience into a structured issue → cause → fix system that supports practical redevelopment under limited time and resources.

Purpose of this page

Record what actually failed or caused recurring field problems.
Separate minor noise from issues that materially affect containment performance.
Link failures to design, material, installation, or supplier causes.
Turn practical experience into a focused improvement roadmap.
Preserve technical problem-solving knowledge that would otherwise be lost.

Use rule

Do not use this page to complain or collect random stories. Every entry should help answer one question: what failed, why did it fail, and what is the most practical fix? Keep entries specific, useful, and connected to action.

Improvement logic

1. Observe the issue

What happened in the field, at the component, or during installation?

2. Identify the cause

Was it design-related, material-related, supplier-related, environment-related, or user-related?

3. Define the fix

Choose the smallest practical improvement that materially reduces repeat failure or field difficulty.

Master failure / improvement register

Issue ID	Product / Area	Failure / Problem	Field Condition	Likely Cause	Current Workaround	Proposed Improvement	Priority	Status	Notes
FI-001	CTU-002 / sealing area	Leakage around sealing interface	Field operation / extended use	Seal wear, material inconsistency, or imperfect fit	Replace seal-related parts as needed	Review sealing geometry, material consistency, and contact pressure	High	Open	One of the most likely high-value improvement areas.
FI-002	Mechanical fitting	Installation difficulty or inconsistent fit	Different field setups / variation by well	Dimensional variation, unclear interface, or assembly dependency	Manual adjustment / field judgment	Standardize fitting details and record variation-specific guidance	High	Open	Important because it affects both function and ease of use.
FI-003	Coating / finish	Surface degradation over time	Outdoor field exposure	Environmental wear, coating choice, or application inconsistency	Repair or replace affected parts	Review coating specification and actual field durability	Medium	Open	Track if this is cosmetic or functionally significant.
FI-004	Rain guard / top-side area	Weather exposure still affecting performance	Harsh weather / long field life	Incomplete protection or accessory limitation	Add or adjust protective accessories	Refine top-side protection and clarify when rain guard is mandatory	Medium	Open	May connect directly to accessory strategy.
FI-005	Overflow risk / containment monitoring	Containment fills without active warning or shutdown logic	Leak event / unattended condition	No built-in level safety or alert function	Manual inspection / reactive service	Integrate float switch / level safety module as upgrade path	High	Defined	This is a strong leverage point because development is already completed.
FI-006	Replacement parts support	Recurring service items not clearly structured	After-sales / maintenance support	Accessory knowledge not centralized	Handle case by case	Build clear accessory and replacement structure	Medium	In progress	Directly supported by the Accessories & Components page.
FI-007	Supplier-dependent component	Part availability or quality inconsistency	Procurement / rebuild / service	Single-source dependency or undocumented alternates	Use known source when available	Map primary and alternate suppliers for critical parts	Medium	Open	Important for long-term control recovery.

Replace placeholder rows with real field issues as you document them. Add only failures that affect performance, service burden, cost, or repeatability.

Failure categories to use

Design: geometry, interface, fit, accessibility, structure.
Material: seal wear, coating, corrosion, environmental durability.
Installation: field fit, variation, inconsistent assembly.
Operational: overflow, monitoring gap, maintenance difficulty.
Supply chain: vendor inconsistency, sourcing risk, undocumented alternates.

Priority filter

Does this issue affect containment performance?
Does it create repeat field support burden?
Does it affect installed-base retention or replacement revenue?
Can a small design or sourcing fix reduce future pain meaningfully?
Does it connect to a leverage point like level safety?

Suggested review cycle

1. Log the issue

Enter the actual problem, where it occurs, and under what condition.

2. Rank the impact

Decide whether it is high, medium, or low based on performance and recurrence.

3. Link the fix

Connect the entry to BOM, Accessories, Core System, or Float Switch pages where needed.

Internal guidance

This page is where ten years of practical technical experience becomes a real asset. Do not chase theoretical perfection. Focus on the repeated field failures, the known technical weaknesses, and the smallest improvements that can protect current relevance or strengthen independent rebuild capability.
