DROPS Overview


Dropped Objects Survey Standards

• First published in 2009 to standardise DROPS surveys across the fleet

• Before its publication, scope, report format and methodology of DROPS surveys were left largely to the survey companies

• Dropped object survey must be completed every two years by an approved independent survey company

• Dropped Object Inspection picture Book • The Dropped Object Survey report• Failed items list

Failed item list from each rig department



Static DROP Incident

• Aviation warning light fell from the derrick and landed on the pipe deck

• Lens retainer weighed 2.4kg and the total distance dropped = 43 metres

• The lens retainer bounced and deflected off rig structure and then fell across to the starboard aft pipe deck striking the top front of the casing joints that were laid out on deck.


• TOPSET Investigation

• Notification to NOPSEMA

Conducted a review of our DROPS process

• Items passed by Third party – failed

• pass/fail Inspections carried out by Transocean personnel

• Inspection criteria not prescriptive

• Inspection frequencies unrealistic

• Training

Outcomes


Third Party Survey Company requirements lifted

• Meet with Inspectors prior/post mobilisation to Rig

• Inspectors training is up to date – including verification

• Mandate the installation of safety mesh

• The Responsible Person for the area must validate all inspection frequencies.

• If deviations are required, a formal risk assessment must be conducted using the Company approved Risk Matrix

Third Party Survey Company requirements lifted

Y High 3 4 5

Medium 2 3 4

Low 1 2 3

Likelihood of the object dropping • exposed to vibration ?• possibility of collision ?• exposed to weather resulting in corrosion ?• equipment exposed to high wind ?• How robust is the primary fastening method?

Severity• Determine approximate weight• Determine distance the item could drop• FAC/MTC/RWC = Low• LTI = Medium• FAT = High

The level of risk determines inspection frequency


Example DROPS Section Plan

Reference number on the plan match the photograph references on the inspection book i.e. GINF004, GINF005 and GINS003.


• Two day theoretical and Practical Inspection training course based on K2 Rope access training Course

• Training adapted to meet Transocean’s requirements Company DROPS Awareness OJT is a prerequisite

Development of a DROPS Inspectors course


Inspection criteria is now defined –

Knowledge - Detailed inspection criteriaDemonstrate - Use of the Dropped Object Inspection Book

DROPS Inspectors course Training


Roles and Responsibilities

• Drops Inspectors = Drops Champions onboard

• The Rig Subject Matter Expert who ensures compliance with Transocean Dropped Object prevention policy

• Ensure Third party Drops surveys are conducted in accordance with standards – Validate

• Key to effective Steering Committee meetings = ownership

• Verification through Rig WIN plans (What’s Important Now)

• Internal Auditors and Focal points to assist Responsible Persons


Summary

• Improved Third party DROPS Survey standard and deliverables

• Verification that items are adequately closed in maintenance system

• Formalised DROPS inspectors training for Transocean personnel

• Improved ownership of Rig crew performing Inspections
