Titan Spar Reefing Project: An Ecological Strategy for the Gulf
Location: Gulf of America, USA
Client: Equinor ASA
To secure a Special Artificial Reef Site (SARS) permit under Louisiana law, Talos Energy engaged Blue Latitudes to assess marine life on the EC 346A platform structure. Our team developed hydroacoustic and ROV survey protocols, then combined the video and acoustic data to quantify fish abundance by species. A companion vessel-traffic and commercial fisheries review using FishLAT confirmed negligible impacts to other ocean users. The resulting evidence of abundant, diverse marine life gave Talos Energy what it needed to secure the SARS permit from Louisiana's reefing committee.
Platform-Based Marine Environmental Studies in West Africa
Location: Gabon
Client: TotalEnergies
As its offshore platforms along the Gabonese coast near the end of their operational lives, TotalEnergies engaged Blue Latitudes to characterize the marine ecosystems these structures support. Over two field campaigns, our team combined eDNA sampling, ROV surveys, 360° and stereo-video imaging, larval and plankton sampling, and fish telemetry to assess species diversity, habitat use, and movement. The results delivered critical insight into how these platforms function as artificial reefs, informing TotalEnergies' decommissioning strategy and establishing a foundation for future marine research in the region.

Validating a Reefing Viability Index
Location: Malaysia
Client: PETRONAS
PETRONAS developed a Reefing Viability Index (RVI) to identify strong candidates for its Rigs-to-Reefs decommissioning strategy in the South China Sea, and engaged Blue Latitudes to test and strengthen it. Our team refined the RVI's simulation equation and hydrodynamic model for coral larva transport, and added new fisheries parameters. To validate the improved index, Blue Latitudes conducted ROV surveys of coral, fish, and invertebrate life on PETRONAS's platforms — among the first such assessments in the region — and built a commercial fishing effort model using AIS and VIIRS vessel-detection data. The results, shared through a scientific manuscript and stakeholder video, now help PETRONAS assess risk and prioritize sustainable reefing decisions.
Charting a Path to Aquaculture Permitting
Location: California, USA
Client: Malibu Oyster Company
Malibu Oyster Company engaged Blue Latitudes to help pursue a California state bottom lease for growing oysters and kelp. Our team identified the regulatory constraints on aquaculture permitting in California and outlined ways to streamline the process while maintaining compliance with the California Environmental Quality Act (CEQA) and other statutory requirements. Blue Latitudes provided permitting guidance, long-range planning support, and a communications strategy, all incorporated into the company's final pre-proposal submittal to the Pacific States Marine Fisheries Commission.
Ranking 900 Reef Sites Down to 40
Location: Coastal Louisiana, USA
Client: Coastal Conservation Association (CCA)
The Coastal Conservation Association asked Blue Latitudes to help narrow a pool of 900 candidate sites down to the 40 best locations for future artificial reefs across coastal Louisiana. Using FishLAT, our team ranked each site by commercial and recreational fishing opportunity, fish habitat value, and logistical feasibility, giving CCA a clear, defensible hierarchy of the most suitable sites for reef development.
Clearing the Way for the Nansen Spar Hull
Location: Gulf of America, USA
Client: Anadarko Petroleum Corporation
Anadarko turned to Blue Latitudes to assess commercial fishing pressure and vessel traffic ahead of reefing the Nansen spar hull. Using FishLAT, our team identified potential space-use conflicts, navigational hazards, and active fisheries within the proposed reef site, giving Anadarko a clear picture of the impacts and benefits the reefed hull would create for fisheries stakeholders and other ocean users.
Location: Gulf of America, USA
Client: Anadarko Petroleum Corporation
Blue Latitudes assessed commercial fishing activity around two reefed topside structures — East Cameron 270A and South Marsh Island 205B — to determine the value these structures provide to Gulf of Mexico fisheries. Our team analyzed spatial data from AIS, VIIRS, and VMS vessel-tracking technologies, quantifying fishing effort through hotspot analysis in ArcGIS and mapping tools developed with Global Fishing Watch. The findings gave Anadarko the evidence needed to engage regulators and stakeholders on decommissioning the remaining topside structure.
Measuring the Fisheries Value of Reefed Topsides
A Global Playbook for Rigs-to-Reefs
Location: Peru
Client: VIGO Energy
Blue Latitudes conducted a comprehensive review of Rigs-to-Reefs programs worldwide, covering legal and regulatory frameworks, environmental considerations, and case studies of successful projects. The resulting report gave VIGO Energy a foundation for engaging Peruvian regulators on a national decommissioning framework grounded in international best practice. To build public support, Blue Latitudes also produced an outreach brochure featuring Peru-specific data, infographics, and biodiversity highlights on the benefits of reefing.
A Second Life for East Breaks 110
Location: Gulf of America, USA
Client: Confidential*
Blue Latitudes led pre- and post-reefing ROV surveys on the East Breaks 110 platform to support its conversion via the partial removal method. The pre-reefing survey established a baseline of the ecological biodiversity and abundance associated with the structure; the post-reefing survey then tracked biological recruitment and colonization on the reefed structure, providing evidence that partial removal reefing can deliver real environmental benefit.
The First Sub-1,000-Foot Subsea Decommissioning
Location: Gulf of America, USA
Client: Confidential*
Blue Latitudes led pre- and post-reefing ROV surveys on the East Breaks 110 platform to support its conversion via the partial removal method. The pre-reefing survey established a baseline of the ecological biodiversity and abundance associated with the structure; the post-reefing survey then tracked biological recruitment and colonization on the reefed structure, providing evidence that partial removal reefing can deliver real environmental benefit.
Reefing the Third Spar Ever Decommissioned
Location: Gulf of America, USA
Client: Anadarko Petroleum Corporation
Blue Latitudes led pre- and post-reefing ROV surveys on the East Breaks 110 platform to support its conversion via the partial removal method. The pre-reefing survey established a baseline of the ecological biodiversity and abundance associated with the structure; the post-reefing survey then tracked biological recruitment and colonization on the reefed structure, providing evidence that partial removal reefing can deliver real environmental benefit.
Weighing the Future of the Beta Field
Location: California, USA
Client: Amplify Energy
Amplify Energy asked Blue Latitudes to help evaluate decommissioning options for its platforms in the Beta Field, offshore Huntington Beach — including a possible Rigs-to-Reefs conversion. Our team conducted a literature review, analyzed archived ROV maintenance footage, assessed fishing patterns, and completed a new ROV-based marine life survey of the platforms. Together, these studies helped Amplify identify the opportunities and constraints of converting its platforms into permanent artificial reefs.
Setting Mauritania's First Decommissioning Precedent
Location: Mauritania
Client: Deloitte (on behalf of the Government of Mauritania)
After more than a decade in operation, the Chinguetti oil field faced decommissioning, and its operator proposed the country's first Abandonment and Decommissioning Plan (A&DP) and Environmental Impact Study. Deloitte engaged Blue Latitudes to guide the Government of Mauritania through its review, drawing on international regulations and industry best practices to advise the Ministry of Petroleum on environmental considerations for the plan. The review helped Mauritania approve its first A&DP and set a precedent for sustainable decommissioning across future projects in the country.
