Hurricane resilience in Caribbean marinas

[edit] Introduction

Marinas are coastal infrastructure that sit directly in the path of tropical storms. In the Caribbean, where hurricanes regularly reach Category 4 and 5 strength, a marina must protect vessels, keep its fixed and floating structures intact, and return to operation quickly after an event, because restaurants, repair yards, charter operators and fishing communities depend on it.

This article sets out the main design and operating considerations for hurricane-resilient marinas, using the post-2017 rebuilding of marinas in eastern Puerto Rico as a case study.

[edit] How hurricanes damage marinas

Most damage comes from a combination of:

• Wave action: waves entering the basin lift and twist docks, overload connections and drive vessels into one another.
• Storm surge: a rise in water level can lift floating docks above the top of their guide piles, or submerge fixed docks and services.
• Wind loading: high winds act on vessels, roofs, dry-stack buildings and loose equipment, generating debris.
• Failure of moorings and connections: cleats, lines, pile guides and gangways are often the weakest points in an otherwise sound structure.
• Loss of utilities: electrical pedestals, fuel systems and water supply are vulnerable to flooding and saltwater intrusion.

[edit] Design measures

[edit] Floating docks rated for extreme conditions

Floating docks rise and fall with the water level, which makes them better suited to storm surge than fixed timber piers. Heavy concrete floating dock systems, held by piles tall enough for the design surge, give greater mass and stability than lightweight timber or plastic systems. Specifying the dock system, pile height and connections for a defined hurricane category is central to resilient design.

[edit] Wave attenuation

A wave attenuator reduces the wave energy reaching the berths. Fixed breakwaters are effective but costly and can alter sediment movement and habitats. Floating wave attenuators, which are large moored floating structures, can reduce wave height inside a basin with a smaller environmental footprint, although they are generally most effective against shorter-period waves. Their design usually needs input from coastal engineers and environmental regulators.

[edit] Dry-stack storage

Covered dry-stack buildings store smaller boats on racks above the water. Designed to suitable wind loads, they remove vessels from the water during storms and reduce the number of boats at risk in the basin.

[edit] Utilities and services

Raising electrical equipment, specifying marine-grade components, providing isolation points and planning fuel-system shutdown all reduce post-storm repair time and safety risks.

[edit] Operational measures

Physical design is only part of resilience. Marinas also rely on:

• hurricane plans that set out when boats must be hauled out, relocated or double-moored;
• clear obligations for tenants and boat owners in berth agreements;
• inspection regimes for lines, cleats and pile guides before each season;
• pre-arranged contractors, materials and insurance procedures for rapid recovery.

[edit] Case study: eastern Puerto Rico after Irma and María

Hurricanes Irma and María struck Puerto Rico in September 2017 and caused severe damage to marinas on the island's east coast. Grand Caribbean Marinas, which operates six marinas around Fajardo, has invested about $50 million in rebuilding and upgrading since then, according to News is my Business [1].

The reported measures include:

• replacing wooden docks with floating concrete docks designed for Category 4 to 5 conditions;
• developing a floating wave attenuator at Marina Puerto Chico, with the involvement of Puerto Rico's Department of Natural and Environmental Resources (DRNA) and the US Fish and Wildlife Service;
• a covered dry-stack facility at Renaissance Villa Marina;
• renovating the fishermen's boat ramp at Marina Sardinera, working with the local fishermen's association [1].

The marinas now support about 50 businesses and roughly 1,000 direct and indirect jobs, including restaurants, mechanics and more than 30 charter operators [1]. The case shows that resilience investment protects the economic activity that depends on a marina as well as the structures themselves.

[edit] Policy considerations

Resilience projects in the coastal zone often face long permitting timelines, because they involve several regulators and environmental assessments. Operators in Puerto Rico have called for faster permitting of resilience projects, shared funding for coastal protection and incentives for marine tourism [1]. Grant programmes such as the US Boating Infrastructure Grant programme can help fund facilities for visiting boaters.
