Top Drive Systems DROPS workshop Integrating ModuSpec and WEST - PowerPoint PPT Presentation

Lloyd’s Register Energy - Drilling DROPS forum 28 November 2013 – Brunei Tom van Pelt Top Drive Systems DROPS workshop Integrating ModuSpec and WEST Engineering Services to advance excellence in drilling safety, integrity and performance

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 •

Lloyd’s Register Energy - Drilling

Lloyd’s Register Energy - Drilling Objective To facilitate a joint industry discussion with the objective of • identifying and exploring opportunities to minimise the occurrences of dropped objects. Opportunities to be found in design (equipment) and in the use • of equipment (people, management systems). Scope was limited to Top Drive System and associated • equipment. Four topics derived from incident and inspection data. •

Lloyd’s Register Energy - Drilling Focus New TDS Systems (looking forward) • New designs and automation TDS Systems in use (current) • Existing conventional

Lloyd’s Register Energy - Drilling 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

Lloyd’s Register Energy - Drilling Production Line

Lloyd’s Register Energy - Drilling 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

Lloyd’s Register Energy - Drilling 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

Lloyd’s Register Energy - Drilling Examples

Lloyd’s Register Energy - Drilling 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 Integrated retention and securing
