Produced from selected materials of the highest quality. BSUK’s Rotary Drilling Lines are used in many of the world’s on-shore and offshore fields. Manufactured in accordance with standards laid down by the API and ISO – ANSI/API Specification 9A and ISO 10425.

Exhaustive field trials were carried out over a three year period on a semi-submersible rig operating in the North Sea. At regular slip and cut intervals, samples of the drill line were taken and subjected to detailed examination and test to determine the condition of the rope. By careful management the ton/miles achieved were increased by more than 50% at the conclusion of the trials compared with the ton/mile interval for a ‘standard’ construction drill line.

For slipping and cut off practice for Rotary Drilling Lines refer to API 9B, Recommended Practice on Application, Care and Use of Wire Rope for Oilfield Service.
