28 November 2013 – Brunei Tom van Pelt

Top Drive Systems DROPS workshop

Lloyd’s Register Energy - Drilling

Background to TDS DROPS workshop

• Originally initiated and fully supported by Brunei Shell Petroleum

Company

• Based on incident data provided by Brunei Shell Petroleum

Company

• Supported by historical data available within Lloyds Register

Energy Drilling inspection records

• Participation of operators, rig owners and manufacturer

Objective

• To facilitate a joint industry discussion with the objective of

identifying and exploring opportunities to minimise the

• ccurrences of dropped objects.
• Opportunities to be found in design (equipment) and in the use
• f equipment (people, management systems).
• Scope was limited to Top Drive System and associated

equipment.

• Four topics derived from incident and inspection data.

Focus

• New TDS Systems (looking forward)

New designs and automation

• TDS Systems in use (current)

Existing conventional

Topic - Collisions

• Findings

Collisions between top drive and structure or stand while the top drive is moving

• Contributing factor

Human error / procedure

• Topics to explore

Zone management / interlock systems Training

Topic - Failed fixing and securing

• Findings

Sheared bolts, loose bolts and nuts

• Contributing factor

Insufficient design Maintenance and inspection Operational factors (vibration, weather)

• Topics to explore

Alternative fixing methods Integrated securing Improve visibility and detectability of defects

Topic - Maintenance, Inspection and Replacement

• Findings

Secondary retention / securing not returned correctly after maintenance or repair activities

• Contributing factor

Insufficient training or complicated situation Availability of correct tools and securing aids (correct split pin) Sufficient time for maintenance / procedure in place (checks)

• Topics to explore

Reduce and simplify amount and diversity of fastening / securing Maintenance & replacement schedule for fastening & securing

Topic - (Sub)vendor supplied parts

• Findings

Blower motor & cover incidents

• Contributing factor

Supplied parts are not designed with DROPS in mind

• Topics to explore

Ensure (sub)vendor supplied parts are risk assessed and have adequate fixing and integral securing
