3 Terms and Definitions
For the purpose of this document, the following terms and definitions apply.
3.1 Deck
The area on the self-elevating drilling unit that is used to store all equipment, bulk materials, tools, and for the personnel's daily activities and work.
3.2 Deck load
Design the maximum load that the deck structure of each part of the self-elevating drilling unit can withstand.
NOTE: The unit is N/m2 or kN/m2.
In addition to the main functional areas in 5.1.1~5.1.4, the deck storing areas that are specifically defined due to the requirements of the technical specifications of contract or to meet the specific functional requirements.
5 Design Method
5.2 General requirements
