## What is SIRE and CDI?

**SIRE (Ship Inspection Report Programme)** <img src="https://mintcdn.com/siya-6e67d02e/_4Aly_GdIn4oDjms/assets/ocimf-logo.jpg?fit=max&auto=format&n=_4Aly_GdIn4oDjms&q=85&s=3cecafd68adcb5b86b01e17536e52590" alt="OCIMF Logo" style={{width: '60px', height: 'auto', display: 'inline-block', marginLeft: '10px', verticalAlign: 'middle'}} width="670" height="479" data-path="assets/ocimf-logo.jpg" />

SIRE is the world's leading vessel inspection database operated by OCIMF (Oil Companies International Marine Forum). SIRE provides comprehensive inspection reports for tankers, gas carriers, and offshore vessels, serving as the industry standard for vetting inspections. Major oil companies and charterers rely on SIRE data to assess vessel quality, safety standards, and operational capabilities before chartering decisions.

## Compliance Calculations

### SIRE Validity Logic:

**Days Remaining** = (Last Inspection Date + 180 days) - Current Date

**Status** = $\begin{cases}
\text{Valid} & \text{if Days Remaining} > 30 \\
\text{Due Soon} & \text{if } 0 \leq \text{Days Remaining} \leq 30 \\
\text{Overdue} & \text{if Days Remaining} < 0 \\
\text{Not Available} & \text{if no inspection data}
\end{cases}$

**Where:**

* SIRE inspection validity period = 180 days from inspection date
* Valid: More than 30 days remaining before expiry
* Due Soon: Between 0-30 days remaining before expiry
* Overdue: Past the 180-day validity period

### CDI Validity Logic:

**Days Remaining** = (Last Inspection Date + 365 days) - Current Date

**Status** = $\begin{cases}
\text{Valid} & \text{if Days Remaining} > 60 \\
\text{Due Soon} & \text{if } 0 \leq \text{Days Remaining} \leq 60 \\
\text{Overdue} & \text{if Days Remaining} < 0 \\
\text{Not Available} & \text{if no inspection data}
\end{cases}$

**Where:**

**Where:**

* CDI inspection validity period = 365 days from inspection date
* Valid: More than 60 days remaining before expiry
* Due Soon: Between 0-60 days remaining before expiry
* Overdue: Past the 365-day validity period
