DROPPED OBJECTS
PREVENTION
SYSTEM OVERVIEW
NOBLE DROPPED OBJECTS PREVENTION
 Noble Drilling began implementing a derrick dropped
object campaign within the European mobile fleet in 1998
which has since been extended to other Noble divisions
(Was also introduced onto client owned fixed installations)
 This drive to reduce the potential of dropped objects is based on
competent third party inspections and scheduled maintenance
procedures being carried out, with all discrepancies found being
actioned through the correct reporting channels.
 Maintenance schedules include annual third party surveys and
weekly routines carried out by members of the rig crew.
 The annual third party survey consists of both a derrick inventory
check and a derrick structural inspection in accordance with API
specifications
 In order to ensure all parties maintain consistency, the derrick is
divided into seven standard areas (slide 4)
 The complete Noble derrick inspection process is shown on page 3
of the DIM introduction and the following slide

Objectives
To reduce the potential of dropped objects from derricks by the
following means;
 By performing initial derrick structural inspections and derrick
inventories with experienced and competent third party vendors.
 By removing redundant equipment highlighted within the derrick
inventory.
 By closing out all defects at the time of detection or as soon as
practicable.
 By ensuring any outstanding defects are highlighted within the
maintenance system and appropriate correct action request raised.
 By maintaining a ‘live’ derrick inventory through weekly and annual
maintenance routines.
 By ensuring all relevant safety alerts, policy changes, etc. are
forwarded and implemented where appropriate.
