Las Palmas Port Muelle: A 45.3 Million Euro Engineering Feat 2026

The Port of Las Palmas is set to undergo a significant transformation with the construction of a new muelle (quay) attached to the Reina Sofía Sur breakwater. The project, authorized for tender by the Spanish Government in July, carries a budget of 45.3 million euros (excluding IGIC) and promises to enhance the port's capacity to handle large vessels. But beyond the surface, this engineering endeavor involves a hidden challenge: a massive amount of rock beneath the sea that must be addressed before construction can begin.

At first glance, building a quay might seem straightforward: erect a structure by the sea, prepare a resistant surface, and leave space for ships to dock. However, a crucial part of these infrastructures lies underwater, where engineers must contend with depth, terrain characteristics, and the immense weight the structure will bear. It is precisely there, long before the first ship arrives, that one of the greatest challenges of port engineering begins.

Project Overview: What Is Being Built?

The new quay will be attached to the existing Reina Sofía Sur breakwater and will feature a water depth of 20 meters alongside the berthing front. This depth is designed to facilitate operations with large ships, positioning the port as a key hub for maritime traffic in the region. The project is still in the tender phase, but its design already outlines a complex operation that starts well before the quay itself is built.

The budget of 45.3 million euros (without IGIC) reflects the scale of the undertaking. The Ministry of Transport has highlighted that the infrastructure will be equipped to handle the demands of modern maritime trade, which increasingly relies on larger vessels. The Canary Islands' strategic location makes this development particularly important for both local and international shipping routes.

The Hidden Challenge: Rock Beneath the Sea

One particularity of this type of construction is that the greater the water depth, the more demanding it can be to build a structure that reaches the surface. In the case of the Las Palmas project, engineers must deal with a significant amount of rock hidden beneath the seabed. This rock must be removed or managed before the quay can be built, adding complexity and cost to the project.

The presence of rock poses several challenges. First, it requires specialized equipment for underwater excavation, such as dredgers and rock cutters. Second, it demands careful planning to ensure that the removal process does not disrupt the marine environment or the existing port operations. Finally, the rock itself must be disposed of or reused appropriately, which can impact the overall budget and timeline.

Why Underwater Rock Matters

Underwater rock is not just an obstacle; it also affects the stability of the quay. The structure must be anchored securely to the seabed to withstand the forces of tides, waves, and the weight of the ships. If the rock is not properly addressed, it could lead to settlement or failure of the quay. Therefore, engineers must conduct thorough geotechnical surveys to understand the rock's composition and distribution.

Moreover, the depth of 20 meters means that divers and remotely operated vehicles (ROVs) will be essential for inspection and construction tasks. Working at such depths requires specialized techniques and safety measures, further complicating the operation.

Engineering Steps: From Seabed to Surface

The construction process for the new quay will likely follow a sequence of carefully planned steps. Although the exact methodology may vary, the general approach includes:

• Geotechnical investigation: Detailed surveys of the seabed to map the rock and soil conditions.
• Dredging and rock removal: Excavation of the seabed to create a stable foundation, including breaking and removing rock.
• Foundation construction: Installation of piles or caissons to support the quay structure.
• Quay wall erection: Building the vertical face of the quay, often using concrete blocks or steel sheet piles.
• Surface preparation: Creating the deck for cargo handling and mooring systems.

Each step is interdependent, and delays in one phase can cascade through the entire project. The rock removal phase, in particular, is critical because it sets the stage for all subsequent work.

Comparison with Other Port Projects

To appreciate the scale of the Las Palmas project, it helps to compare it with other port developments. The table below outlines key parameters of similar quay projects.

While the Las Palmas project is smaller in budget compared to these mega-projects, its specific challenge of underwater rock in deep water makes it a notable engineering feat. The 20-meter depth is on par with some of the world's largest ports, indicating the ambition behind this development.

Economic and Strategic Impact

The new quay is expected to boost the Port of Las Palmas' competitiveness by attracting larger vessels and increasing cargo throughput. The Canary Islands are a key stopover for transatlantic routes and a gateway to West Africa. Enhanced facilities could lead to more shipping lines including Las Palmas in their schedules, benefiting the local economy through increased trade and job creation.

Additionally, the project aligns with broader efforts to modernize Spain's port infrastructure. The government's investment in such projects underscores the importance of maritime transport in the national economy. As global trade evolves, ports must adapt to handle larger ships and more efficient operations. The background to this story is set out in Science: latest articles.

What to Watch Next

The tender process is currently underway, and the contract award will be a key milestone. Once awarded, the selected contractor will need to finalize the design and begin the underwater work. Environmental permits and mitigation measures will also be critical, as the rock removal could affect marine habitats.

Stakeholders should monitor the project's progress, particularly the geotechnical findings and the methods chosen for rock removal. These early stages will determine the feasibility and timeline of the entire construction. With careful planning and execution, the new quay could become a model for deep-water port engineering in challenging geological conditions.
