MAST API 4F FOURTH EDITION GENERAL SPEC GUIDELINE

LCI mast is designed to withstand a wind of 69 mph from any direction provided the four jacks on the vehicle are properly deployed and guying per API is done. Telescoping structural mast is designed and constructed to API standard Spec 4-F (Fourth Edition) and API Spec Q-1 quality control (Eighth Edition) and bears the API monogram. The Product Specifcation Level for this mast is PSL 1, and the Structural Safety Level (SSL) is E2-U2.

Section 4: Product Specification Levels (PSL)… PSL 1 Required The level of material and process controls placed upon primary load-carrying components of covered equipment.

Note: 1 knot = 1.15 miles per hour = 0.514 meters per second The expected and unexpected storm wind data may be specified in one of the following manners:

1. Directly specified by the purchaser in knots: The expected wind velocity specified shall be a 3-second gust wind, in knots, measured at 10 m (33 ft) in open terrain with an associated wind return period of 50 years for the land regions where the rig will operate.

The unexpected wind velocity shall be not less than 75% of the expected wind velocity. 2. Specified by the required Structural Safety Level (SSL; refer to Section 6) and the various regions where

the structures shall operate. The manufacturer shall determine the appropriate design wind speeds using data from a recognized standards or governmental meteorological agency for the regions of intended use. Example: ASCE/SEI 7-05 is used for data in the continental United States. Note that for some regions in the world, such meteorological data is not readily available and the purchaser and manufacturer should agree on appropriate design wind speeds.

Expected Vref = 75 knots Unexpected Vref = 60 knots

Section 8.3.1.2: Offshore Wind Design Criteria… Not required Section 8.4: Dynamic Loads… Not required Section 8.5: Earthquake Load… Required upon special application. Earthquake consideration is a special loading condition to be specified by the user. The purchaser is responsible to provide all design criteria for the seismic zone in which the drilling unit shall operate. Section 8.7: Erection Loads… Reference Standard Equipment Spec Per API requirements, each drilling structure shall be designed for erection loads in combination with dead loads and erection wind. Any additional erection loads, wind, inertial, or other, shall be specified by purchaser. Section 8.8: Transportation Loads… Reference Standard Equipment Spec Per API requirements, each drilling structure shall be designed for transportation loads in combination with dead loads and transportation environment wind. Any additional transportation loads, wind, inertial, or other, shall be specified by purchaser. Section 8.9: Overturning and Sliding… Reference Standard Equipment Spec Distribution of any foundation support reactions shall be limited to comply with allowable design loadings of the supporting structures foundations, if specified by the purchaser. Manufacturer shall include diagrams defining the maximum foundation support loads based on the factored lateral loads with rig instructions. For example, ground supported land drilling structures might be specified to be supported on rig mats with an appropriate limitation on the maximum allowable ground bearing pressure.
