Maritime Energy Briefing: Gulf of Mexico Subsea Development Advances as Wave Power Project Gains Momentum in Portugal

## Gulf of Mexico Subsea Tie-Back Gets the Green Light U.S.-headquartered LLOG Exploration, a subsidiary of London-listed Harbour Energy, has taken a final investment decision to proceed with a subsea tie-back development connected to an existing floating production system (FPS) in the Gulf of America — the U.S. Gulf of Mexico — according to Offshore Energy. The move underscores continued operator confidence in deepwater Gulf infrastructure, where tie-back developments offer a cost-efficient route to monetising satellite discoveries by leveraging existing production facilities rather than constructing standalone platforms. For LLOG, a privately held independent with a strong track record in deepwater Gulf operations, the decision signals ongoing commitment to the basin under its Harbour Energy parentage following the major acquisition completed in 2024. Details on the specific field location, water depth, and anticipated production volumes were not disclosed at this stage, but tie-back projects of this nature typically carry shorter development timelines and lower capital expenditure profiles than greenfield deepwater schemes, making them attractive in the current commodity price environment. --- ## Eco Wave Power Advances Portugal Wave Energy Project In the renewable offshore energy space, Eco Wave Power Global has announced that the Administration of the Port of Douro and Leixões (APDL) has officially commenced rehabilitation works on the Barra do Douro breakwater in Porto, Portugal — a critical enabling step for the company's planned 1 MW wave energy installation, according to a company statement via PR Newswire. Eco Wave Power CEO Inna Braverman is scheduled to meet with APDL representatives and key Portuguese subcontractors in August to coordinate the breakwater completion timeline, installation readiness, and a grid-connection extension for the first 1 MW phase of the project. The project represents a significant milestone for wave energy technology, which has historically struggled to reach commercial-scale deployment. By attaching its proprietary wave energy converters to existing coastal infrastructure such as breakwaters and jetties, Eco Wave Power aims to reduce installation costs and simplify grid connection — a model that has attracted interest from port authorities across Europe and beyond. The Portugal project, developed in partnership with APDL, is positioned as a flagship demonstration of the technology's viability at the 1 MW scale, with potential implications for future deployments at port facilities globally. --- *Sources: Offshore Energy, PR Newswire*
