§250.282 Do I have to conduct post-approval monitoring?
The Regional Supervisor may direct you to conduct monitoring programs. You must retain
copies of all monitoring data obtained or derived from your monitoring programs and make them
available to BSEE upon request. The Regional Supervisor may require you to:

DEEPWATER OPERATIONS PLAN (DWOP)
Back to Top
§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
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 non-conventional, 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.
Back to Top
§250.289 What must the Conceptual Plan contain?
In the Conceptual Plan, you must explain the general design basis and philosophy that you will
use to develop the field. You must include the following information:

(a) An overview of the development concept(s);
(b) A well location plat;
(c) The system control type (i.e., direct hydraulic or electro-hydraulic); and
(d) The distance from each of the wells to the host platform.
Back to Top
§250.290 What operations require approval of the Conceptual Plan?
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.
Back to Top
§250.292 What must the DWOP contain?
You must include the following information in your DWOP:
(a) A description and schematic of the typical wellbore, casing, and completion;
(b) Structural design, fabrication, and installation information for each surface system, including
host facilities;
(c) Design, fabrication, and installation information on the mooring systems for each surface
system;
(d) Information on any active stationkeeping system(s) involving thrusters or other means of
propulsion used with a surface system;
(e) Information concerning the drilling and completion systems;
(f) Design and fabrication information for each riser system (e.g., drilling, workover, production,
and injection);
(g) Pipeline information;

(h) Information about the design, fabrication, and operation of an offtake system for transferring
produced hydrocarbons to a transport vessel;
(i) Information about subsea wells and associated systems that constitute all or part of a single
project development covered by the DWOP;
(j) Flow schematics and Safety Analysis Function Evaluation (SAFE) charts (API RP 14C,
subsection 4.3c, incorporated by reference in §250.198) of the production system from the Surface
Controlled Subsurface Safety Valve (SCSSV) downstream to the first item of separation equipment;
(k) A description of the surface/subsea safety system and emergency support systems to
include a table that depicts what valves will close, at what times, and for what events or reasons;
(l) A general description of the operating procedures, including a table summarizing the
curtailment of production and offloading based on operational considerations;
(m) A description of the facility installation and commissioning procedure;
(n) A discussion of any new technology that affects hydrocarbon recovery systems;
(o) A list of any alternate compliance procedures or departures for which you anticipate
requesting approval;
(p) If you propose to use a pipeline free standing hybrid riser (FSHR) on a permanent
installation that utilizes a buoyancy air can suspended from the top of the riser, you must provide the
following information in your DWOP in the discussions required by paragraphs (f) and (g) of this
section:
(1) A detailed description and drawings of the FSHR, buoy, and the associated connection
system;
(2) Detailed information regarding the system used to connect the FSHR to the buoyancy air
can, and associated redundancies; and
(3) Descriptions of your monitoring system and monitoring plan to monitor the pipeline FSHR
and the associated connection system for fatigue, stress, and any other abnormal condition (e.g.,
corrosion) that may negatively impact the riser system's integrity.
(q) Payment of the service fee listed in §250.125.

§250.294 May I combine the Conceptual Plan and the DWOP?
If your development project meets the following criteria, you may submit a combined
Conceptual Plan/DWOP on or before the deadline for submitting the Conceptual Plan.
(a) The project is located in water depths of less than 400 meters (1,312 feet); and
(b) The project is similar to projects involving non-conventional production or completion
technology for which you have obtained approval previously.
Back to Top
§250.295 When must I revise my DWOP?
You must revise either the Conceptual Plan or your DWOP to reflect changes in your
development project that materially alter the facilities, equipment, and systems described in your
plan. You must submit the revision within 60 days after any material change to the information
required for that part of your plan.
