Solution

Mainly there are two types of failure modes. They are that occur instantly after installation such as:

During design:

Most failure, and almost all fitting failures, can be banned by ensuring that the plan, build, preservation and examination of the tube or force boat are carried out to a recognized Code or normal.

Another effectual method is evidence testing, which is a customary method for envoy that force vessels and pipelines do not hold flaw that can start catastrophic failure in repair.

In this process, The ship is pressurized with water above the utmost repair stress, and if the part stay alive then the repair circumstances will be safe.

During service:

failure during repair can be due to chronic stresses or ecological situation, cause exhaustion or decay connected problems. Often these issue will be address at the plan stage.

However, fast that has occur during repair can from time to time be analyzed using an ECA(Engineering dangerous assessment)

Fatigue development technique can be used during repair to extend a mechanism life. little flaw that survive the evidence test may produce under recurring load in repair to an extent that they can cause failure of the part during its life.

This can be forbidden by using normal exhaustion design method, or an ECA can be used for flaw found in service. Removing tiny non-metallic intrusions can be abridged by methods like toe grind, and put the weld into local thickness by peening . This will also get better the tiredness life.
