Well control: Deepwater challenges course

IntroductionTraining - Oil and gas - Well control - RAM BOP - 150x112

Learn about what's different (or what should be different) as you extend your operations into deep or ultra deepwater.

This five-day International Association of Drilling Contractors (IADC) accredited course focuses on known and potential issues with drill-through equipment in deep and ultra deepwater, such as hydrostatic pressures external to BOPs (blowout preventers). Drawing on knowledge gained from thousands of rig surveys, this seminar covers advanced multiplex and piloted control systems, BOPs, hydraulic connectors, marine risers and riser tensioners from all major manufacturers, together with the latest know-how on planning, maintenance, and routine, including comprehensive emergency procedures. The latest well control equipment developments from the major OEMs (original equipment manufacturers) is explained in detail.

Learning objective

Learn about what's different (or what should be different) as you extend your operations into deep and ultra deepwater. Covering both DP (dynamically positioned) and deepwater moored rigs, you'll learn about the latest equipment, systems and procedures that enhance well control safety and reduce downtime. It also covers past problems and solutions, so that you can learn from the experiences of others. The practical knowledge gained from this seminar will provide immediate and long-term benefits, allowing you to improve your drilling operations with greater reliability, efficiency and safety while reducing downtime.

Who should attend

Individuals working in the drilling industry who are, or will be, involved with drilling operations and equipment in waters over 3,000 feet deep will find this course very useful. The men on the rig and supporting engineers and managers will benefit from the most comprehensive seminar to date on deepwater drill-through equipment issues.

Delivery method

The course is led by experienced trainers, all of whom are former subsea supervisors as well as senior drill-through equipment surveyors. All trainers have undergone didactical training to enhance their teaching skills. Classroom delivery includes a comprehensive syllabus, supported by modern PowerPoint presentations, computer animations and videos. During this 5-day course ample time is allowed for discussion, both with the instructor as well as amongst candidates themselves.
