The new SOLAS Chapter XV and related IP Code provide requirements for vessels carrying industrial personnel. Key points: - Chapter XV applies to new vessels carrying over 12 industrial personnel and those converting to carry industrial personnel. - The IP Code provides technical requirements for vessels certified under Chapter I or X and requires an Industrial Personnel Safety Certificate. - Requirements vary depending on number of industrial personnel carried and include intact/damage stability, fire safety, lifesaving appliances. - Vessels already certified under interim guidelines must comply with additional requirements by first renewal survey. - Passenger ships may carry industrial personnel without following the IP Code but personnel transfer systems are not covered for passenger ships.

3. 1. INTRODUCTION
- The installation and maintenance of offshore wind complexes requires an increased number of
installation and maintenance personnel to be transferred.
- Request from the industry to NOT regard this transport as passenger vessels.
- Special Purpose Vessel Code NOT to be used for the transport of industrial personnel
- Special Purpose Vessel Code is a non-mandatory code not recognized by a number of flags.
- Take into account mobility of persons to be transported
- Depending on the tasks to be performed, persons may be regarded as industrial personnel on one
trip and special personnel on the next. This would require some flexibility in application.
