INTERPRETATION
“MCA” means the Maritime and Coastguard Agency, an Executive Agency of the Department of the Environment, Transport and the Regions.

“MSPP1” means Maritime Safety and Pollution Prevention Directorate (Ships Business Unit).

“Certifying Authority” means the Secretary of State or any person authorised by the Secretary of State.

“Merchant Shipping Notice (MSN)” means a Notice described as such and issued by the MCA and any reference to a particular Merchant Shipping Notice includes a reference to any document amending or replacing that Notice which is considered by the Secretary of State to be relevant from time to time and is specified in a Merchant Shipping Notice (MSN).

“IMO” means International Maritime Organisation.

INTRODUCTION
These Instructions give guidance on and where necessary clarification of the current Maritime and Coastguard Agency (MCA) standards and policies that should be applied by Marine Surveyors when considering constructional arrangements and conducting surveys related to construction of passenger ships. They are not intended to replace professionalism or experience. It is the surveyor’s expertise in conjunction with that of the owner/operator that should ultimately ensure that passenger ships are built and maintained in accordance with the Regulations and operated in a safe manner. The primary Regulations which are referred to throughout are The Merchant Shipping (Passenger Ship Construction: Ships of Classes I, II and II(A)) Regulations 1998. It is also considered appropriate that these Instructions address the Merchant Shipping (Ro-Ro Passenger Ship Survivability) Regulations 1997 and Part 14 has been given to this task. For completeness the Instructions should be read in conjunction with these Regulations.

Other Regulations referred to which should be considered together with these Instructions are the:

• Merchant Shipping (Weighing of Goods Vehicles and other Cargo) Regulations 1988; SI 1988/1275
• Merchant Shipping (International Safety Management (ISM) Code) Regulations 1998; SI 1998/1561
• Merchant Shipping (Crew Accommodation) Regulations 1997; SI 1997/1508
• Merchant Shipping (Fire Protection: Large Ships) Regulations 1998; SI 1998/1012

The Passenger Ship Construction Regulations are primarily prescriptive but allow for equivalent arrangements to be accepted. Every effort has been made to indicate where it is appropriate for early consultation to establish whether MSPP1 need to be party to the consideration and decisions being made. In considering acceptance of equivalent arrangements, the surveyor should examine the relevant supporting drawings and or documents and where a submission to MSPP1 is necessary the surveyor’s comments and recommendations as appropriate should be included.

Where surveyors accept equivalent arrangements locally, their decisions and supporting documents should be recorded in the appropriate files.

These Instructions are a “live document” and shall be updated from time to time.

Therefore if surveyors feel a need for any areas to be clarified or wish to suggest amendments, they should forward suggestions in suitable detail to MSPP1.
