North Coast of Puerto Rico

Concept.

Puerto Rico has to import natural gas because of the federally mandated MATI rule regarding air emissions. The problem is that local power transmission plants are structured for burning heavy fuel oil. In order to switch to gas, the concepts of burning, fuel preparation, storage, and dispatch controls have to be reviewed.

Furthermore, the case for compressed natural gas is also different since the transportation of this fuel at these volumes (more than 150 mmscfd) has not yet been accomplished for a large size power fleet.

Project Description.

190 mmscfd will be brought from Trinidad and Tobago to Puerto Rico by a virtual pipeline of more than 5 ships. A facility in Trinidad and Tobago will receive the gas and compress it. This gas will be transported for the 600 mile journey to Puerto Rico in panamax ships geared with high pressure coils. In Puerto Rico, the gas will be delivered to the north coast of the island entering San Juan Harbor and delivering right at the entrance of each plant. The gas will be decompressed close to the user.

Outcome.

In order to evaluate this project, a feasibility study with preliminary engineering work was done. The required field work and environmental restrictions had to be investigated to evaluate this multi-billion dollar project.

A thorough evaluation of the product application includes environmental impact on the boats in SJ harbor, engineering evaluation of disposable sites nearby the plants which can lodge the decompression facilities, and discovery of possible intermediate storage facilities. Safety and security regulations related to the harbor and regulating agencies will also be investigated.

Project Highlights.

• Engineers of record
• Unique power project with respect to compressed natural gas
