Pipe Tracking in Shipbuilding: Managing ACC, REJ and Pending

Piping is one of the largest and most fragmented inspection workloads in newbuilding. A single vessel can contain tens of thousands of pipe spools, each fabricated, installed, tested, and inspected across many systems. Keeping track of which spools are accepted, rejected, or still pending is a genuine supervision challenge — and a common source of delay.

The three states of a pipe spool

The status of every spool changes constantly as construction proceeds. Without a live system, teams lose visibility of how many spools are outstanding, where rejections are concentrating, and which systems are at risk of falling behind.

• Accepted (ACC) — the spool has passed inspection and is cleared for the next stage.
• Rejected (REJ) — the spool failed inspection and requires rework or replacement.
• Pending — the spool is awaiting inspection or a decision.

Why spreadsheets break down

Spreadsheets can track pipe status in principle, but they struggle at scale. Multiple people editing, no live totals, no link to the ITP, and no automatic reporting mean the numbers drift out of date almost immediately. When a classification surveyor or owner asks for the current acceptance rate, the answer takes hours to assemble and may already be wrong.

What good pipe tracking looks like

• Automatic categorisation into ACC, REJ, and Pending with live counts
• Status visibility per system, not just per spool
• Direct link to the ITP and inspection records
• Rejection trends surfaced so recurring problems are caught early
• Instant reporting for class and owner reviews

Pipe tracking in ShipInspect Pro

ShipInspect Pro includes a dedicated pipe tracking system that automatically categorises spools into Accepted, Rejected, and Pending with real-time counts across all systems. Because it is integrated with the ITP and the AI reporting engine, the current pipe status is always available and always reflected in your monthly reports — no manual reconciliation required.
