§250.286   What is a DWOP?
(a) A DWOP is a plan that provides sufficient information for BSEE to review a deepwater development project, and any
other project that uses non-conventional production or completion technology, from a total system approach. The DWOP does
not replace, but supplements other submittals required by the regulations such as BOEM Exploration Plans, Development and

eCFR — Code of Federal Regulations

Production Plans, and Development Operations Coordination Documents. BSEE will use the information in your DWOP to
determine whether the project will be developed in an acceptable manner, particularly with respect to operational safety and
environmental protection issues involved with non-conventional production or completion technology.
(b) The DWOP process consists of two parts: a Conceptual Plan and the DWOP. Section 250.289 prescribes what the
Conceptual Plan must contain, and §250.292 prescribes what the DWOP must contain.
Back to Top

§250.287   For what development projects must I submit a DWOP?
You must submit a DWOP for each development project in which you will use non-conventional production or completion
technology, regardless of water depth. If you are unsure whether BSEE considers the technology of your project nonconventional, you must contact the Regional Supervisor for guidance.
Back to Top

§250.288   When and how must I submit the Conceptual Plan?
You must submit four copies, or one hard copy and one electronic version, of the Conceptual Plan to the Regional Director
after you have decided on the general concept(s) for development and before you begin engineering design of the well safety
control system or subsea production systems to be used after well completion.

You may not complete any production well or install the subsea wellhead and well safety control system (often called the
tree) before BSEE has approved the Conceptual Plan.
Back to Top

§250.291   When and how must I submit the DWOP?
You must submit four copies, or one hard copy and one electronic version, of the DWOP to the Regional Director after you
have substantially completed safety system design and before you begin to procure or fabricate the safety and operational
systems (other than the tree), production platforms, pipelines, or other parts of the production system.
