Beach Energy - Otway Offshore Project

Download the attached PDF listed under the 'Docs' column to review the potential work packages for the project. This is not an exhaustive list and additional work packages may be added. Submit your Expression of Interest to receive updates as specific work packages are listed.

The selected facilities consist of a flexible flowline system with sizes between 6inch and 10inch Internal Diameter.

This flowline system is complimented with rigid tie-in spools or flexible jumpers.

As part of this development, Beach have identified the need for subsea structures to tie-back these flexible flowlines. These may include:

- 6 Subsea tree tie-in rigid spools: 5 off
- 4-slot Subsea Central Manifold: 1 off
- Subsea Valve Manifold: 1 off
- Pipeline End Manifolds: 3 off

All equipment will consist of Corrosion Resistant Alloys for all production wetted parts. The spools will connect with Vertical Diverless Connectors.

The above Manifolds will all have ROV operable valves and Vertical and Horizontal Connectors to connect the Rigid spools and Flexible Flowlines. All Manifold will have foundations, either integrated or as a separate lift. Some of the manifolds may have instrumentation.

The Subsea Valve Manifold will contain a Beach provided Subsea Control Module complete with ancillaries.

Beach is seeking Expressions of Interest for potential bidders to provide the above equipment. The Equipment is to be provided as an integrated solution. The Scope of Work would therefore provisionally include:

1. Project Management
2. Safety Management

10. Testing of all Equipment: Factory Acceptance testing of all components, Functional Testing, Hydrotesting/Leak testing, ROV Access simulation.

Beach are currently developing the Otway Phase 5 subsea facilities with a planned first gas date of Q1 2023. As part of the systems design the requirement for subsea metering has been identified to ensure the operability and integrity of the offshore production system and to provide production data for regulatory requirements and reservoir performance.

The scope requirement is to provide a minimum 3 off subsea metering systems that satisfy the primary functional requirements below:

- Measurement of Gas Flow Rate + 10% accuracy;
- Measurement of Formation Water Flow Rate;
- Detect the onset of formation water.

Additional items for consideration:

- Secondary functional requirement to measure condensate flow rate;
- Accuracy statements;
- Track record in Australia;
- Reliability;
- Technology Readiness Level;
- Retrievability (partial or full);
- Power requirements.

Beach are currently developing the Otway Phase 5 subsea facilities.

The selected facilities consist of a flexible flowline system suitable for hydrocarbon operations.

This flowline system is complimented with rigid tie-in spools or short flexible jumpers.

As part of this development, Beach have identified the need for subsea unbonded flexible pipe, to tie-back these subsea facilities. These may include:

- 10inch Internal Diameter Main Production line 3.9km
- 8inch Internal Diameter Infield Production line 4.0km
- 6inch Internal Diameter Infield Production line 1.4km
- 8inch Internal Diameter Infield Production Line 7.9km [Optional]
- 6inch Jumpers 50-100m (5 off) [Optional]

These flowlines are to be fully qualified, designed, manufactured and delivered in accordance with API 17J Specification for Unbonded Flexible Pipeline.

The products will need to be delivered complete with Midline connections (as needed), end-fittings, bend stiffeners/limiters and other ancillaries.

The product needs to be designed for water-depths up to 150m and will have operating temperature between approximately -25C (temporary) and 90C. In addition, it shall be suitable for a Maximum Operating pressure of up to 22MPag.

Beach is seeking Expressions of Interest for potential bidders to provide the above equipment. The Scope of Work would provisionally include:

1. Project Management
2. Safety Management
3. Quality Assurance and Quality Control
4. Procurement Services
5. Engineering
6. Detailed Design
7. Transport & Logistic services (up to delivery)
8. Fabrication/manufacturing
9. Testing of a/Manufacturing of all Equipment
10. Packing of equipment on Transport & Installation Reels
11. Load-out of equipment, either Incoterms 2020 FOB or FAS

Beach have identified that Saturation Diving is necessary to tie-back the Phase 5 facilities, which will involve:

1. Installation and tie-in of a small subsea structure at the Platform base; and
2. Installation of a small subsea structure at a pre-installed Export pipeline Hot Tap location, including execution of the Hot Tap works and stabilisation of the Export pipeline (rock bolting).

Please see attached document for information on the scope of works.

Minimum Scope Requirements: Current Australian Vessel Safety Case for a hydrocarbon environment and a current Saturation Diving Safety Management System

Target Award Date: Early 2021

Design and construction of a cyclonic solids recovery unit installed at the Otway Gas Plant, in the outlet from one of the Slugcatcher Liquids Receivers to filter residual solid material from drilling being transported from the wellbores to the Otway Gas Plant.

The new unit will be installed in a two-stage operation, with the first stage being to install the tie-in points and valving (to be designed) into the process pipework during the February/March 2020 Otway system shutdown. This will enable the clean-up skid to be installed (and subsequently removed) with the Otway Gas Plant online, and without any compromise to production.

The clean-up skid itself will be integrated into a single transportable unit. The active elements of the skid will be scalable to adapt to variations in flowrates, and even to installation in other Beach Energy facilities in the future.
