Dropped Objects Who’s Responsible
Introduction:
Since the introduction of the Dropped Objects Forum one of the biggest challenges to its development has been the perception that DROPS is entirely a Drilling Issue.
This presentation has been developed by the DROPS Forum for the industry. Many thanks are given to those who contributed and if the information given helps to prevent one incident this effort can be considered well spent.
While the presentation is aimed at the UKCS operations it is intended that the lessons learned can be transferred to other theatres of the industry.
Dropped Objects Who’s Responsible
The purpose of this presentation is to:
• Show that a Dropped Object can manifest itself anywhere in the working environment.
• Everybody; Employers, Workers, Drivers, Suppliers, Designers, Maintainers etc. have a moral and legal responsibility to carry out their activities in a safe manner.
• Provide sufficient material to be communicated to relevant personnel for both training and awareness purposes.
