ExxonMobil and its Area 4 co-venturers have awarded approximately US$1.1 billion in pre-investment contracts for long-lead equipment and early project activities supporting the Rovuma LNG Phase 1 development in Cabo Delgado, Mozambique.
The latest awards mark another important step toward the project's Final Investment Decision (FID) and demonstrate that procurement activity is already moving forward ahead of the full project execution phase. The contracts cover critical upstream equipment, including subsea production systems, large-bore production valves and offshore line pipe.
The Rovuma LNG project is being developed in Area 4 of the Rovuma Basin, offshore northern Mozambique, with a planned onshore LNG facility designed to produce approximately 18.6 million tonnes of LNG per year.
The latest procurement awards are focused on equipment and materials that require extended manufacturing and delivery periods.
The major packages include:
· OneSubsea UK Limited and OneSubsea AS — subsea production systems, controls and umbilicals, with in-country support from Aker Solutions Mozambique
· Advanced Technology Valve S.p.A. — large-bore production valves
· Corinth Pipeworks Pipe Industry Single Member S.A. — submerged arc welded (SAW) line pipe
· Sumitomo Corporation of America — seamless (SMLS) line pipe
· Zhejiang Jiuli Hi-Tech Metals Co., Ltd. — mechanically lined pipe, induction bends, weld-overlay products and associated line-pipe systems
The early placement of these packages is intended to secure equipment and materials with long manufacturing schedules before the project reaches full execution.
This is particularly relevant to the wider supply chain because the procurement of long-lead items often precedes the release of additional equipment packages during detailed engineering and EPC execution.
Rovuma LNG is designed to develop significant offshore natural gas resources in Mozambique's Area 4 and connect them to an onshore LNG processing and liquefaction facility.
Phase 1 is planned with 12 modular LNG trains and approximately 18.6 MTPA of LNG production capacity. Current project information points to FID during 2026, with start-up targeted around 2031, subject to project execution and approvals.
The scale of the development means that procurement will extend well beyond the upstream packages already announced.
As engineering advances, the project will require a broad range of process equipment, pressure equipment, heat-transfer equipment, piping systems and corrosion-resistant materials.
For a large LNG and gas-processing development, equipment requirements can include:
· Pressure vessels and separators
· Gas treatment vessels
· Shell & tube heat exchangers
· Condensers and coolers
· Process columns
· Scrubbers and other pressure-containing equipment
· Piping and fittings
· Valves and specialty components
· Machined components for pressure equipment and heat exchangers
The exact equipment packages and specifications for Rovuma LNG will depend on the project's detailed engineering and procurement strategy.
However, these equipment categories are particularly relevant when considering the material supply chain behind LNG and gas-processing facilities.
One important material solution for corrosion-resistant pressure equipment is clad plate, also commonly referred to as clad steel plate.
Clad plate combines a carbon steel or low-alloy steel base plate with a corrosion-resistant alloy layer.
Depending on the process conditions, the cladding material may include:
· Stainless steel
· Duplex stainless steel
· Super duplex stainless steel
· Nickel alloys
· Titanium and other corrosion-resistant alloys
For large pressure vessels and process equipment, stainless steel clad plate can provide a corrosion-resistant process-contact surface while retaining the structural and economic advantages of a carbon steel base.
This can be particularly relevant where equipment is exposed to corrosive gas streams, wet gas, chlorides or other demanding process conditions.
The final material selection for Rovuma LNG will be determined by the process design, operating conditions and project specifications. Nevertheless, in LNG and gas-processing projects, clad steel plate may be considered for selected pressure-containing equipment, including:
Pressure vessels and separators can require corrosion-resistant internal surfaces depending on the process medium and operating environment.
A clad pressure vessel can use a corrosion-resistant alloy layer on the process side while maintaining a carbon-steel base for structural strength.
Gas treatment systems may involve corrosive components or wet-service conditions. Depending on the process chemistry, stainless steel, duplex stainless steel or nickel alloy cladding may be considered.
Large process columns and vessels can require corrosion-resistant internal surfaces. Clad plate can provide an alternative to manufacturing the entire pressure shell from an expensive solid alloy.
Material selection for heat exchangers depends on the process fluid, temperature, pressure and cooling medium.
Potential materials may include carbon steel, stainless steel, duplex stainless steel, nickel alloys, titanium and copper alloys.
For selected large heat-exchanger components, clad plate and clad components can also be considered where corrosion resistance is required on the process-contact surface.
The final material specifications for Rovuma LNG have not been publicly disclosed. Therefore, the following materials should be regarded as potential material groups based on typical LNG and gas-processing applications, rather than confirmed project specifications.
Carbon steel is widely used for pressure equipment, piping and structural applications where the process conditions and corrosion allowance permit.
Stainless steel may be selected for process equipment and components requiring improved resistance to corrosion or wet-service conditions.
Duplex and super duplex stainless steels may be considered where higher mechanical strength and resistance to chloride-containing environments are required.
Nickel alloys can be used for more severe corrosive services where conventional stainless steels may not provide sufficient corrosion resistance.
Titanium and copper-nickel alloys may be considered for selected heat-transfer and cooling-water applications, depending on the process and cooling medium.
For large pressure vessels and process equipment, stainless steel clad plate or nickel alloy clad plate can be considered when corrosion resistance is required without manufacturing the entire pressure-containing component from a solid high-alloy material.
The final selection depends on the process medium, temperature, pressure, corrosion mechanism, design code and customer specification.
