Common Maritime Accidents in Louisiana

Morris & Dewett has handled maritime injury cases for over 25 years.

What Types of Maritime Accidents Happen on Louisiana and Gulf Waters?

Louisiana ranks first in the nation for maritime economic impact. The state’s maritime industry employs 54,850 workers and generates over $11.3 billion annually. Louisiana’s 2,800 miles of navigable waterways move more than 500 million tons of cargo each year. The Port of South Louisiana handles more tonnage than any port in the Western Hemisphere. The Port of New Orleans, the Port of Lake Charles, and the Port of Baton Rouge complete a network of commercial waterways. This network stretches from the Mississippi River delta to the Intracoastal Waterway.

That volume of activity creates risk. Maritime workers face a fatality rate roughly five times the national average for all industries. Nonfatal injury rates run approximately double the overall workforce rate. The types of accidents that cause these injuries range from vessel collisions and crane failures to chemical exposures, mooring line snap-backs, and falls overboard.

Which law governs your claim depends on three things: the type of accident, your status as a worker (seaman, harbor worker, or other), and where the accident occurred. A seaman injured on a vessel in the Gulf of Mexico has different legal options than a longshoreman injured on a dock in New Orleans.

Vessel Collisions and Allisions

collision

A collision in maritime law refers specifically to two moving vessels striking each other. This is distinct from an allision, where a moving vessel strikes a fixed object.

allision

An allision occurs when a moving vessel strikes a stationary object such as a dock, bridge piling, offshore platform, or moored vessel. The legal burden of proof differs from a collision.

Maritime law distinguishes between a collision and an allision. A collision involves two moving vessels. An allision involves a vessel striking a fixed object such as a dock, bridge piling, or offshore platform.

On Louisiana’s inland waterways, collisions happen on the Mississippi River, the Intracoastal Waterway, and the Atchafalaya Basin. Fog, barge traffic, and narrow channels create conditions where navigation errors have serious consequences. Offshore, supply vessel collisions with platforms and drilling rigs occur during crew changes and cargo transfers.

Contributing factors include radar failures, restricted visibility, crew fatigue, and improper lookout procedures. The injuries are severe. Traumatic brain injuries, spinal cord damage, crush injuries, and drowning account for the majority of collision casualties.

The legal framework for your claim depends on your worker status. Seamen bring claims under the Jones Act. Harbor workers injured during loading or unloading operations may have claims under the LHWCA.

Crane and Heavy Lifting Accidents

Crane operations are among the most dangerous activities in the maritime industry. Deck cranes on vessels, offshore platform cranes, and shipyard gantry cranes all present different hazards. Dropped loads, boom failures, rigging failures, and operator error cause crush injuries, amputations, and fatalities.

Platform Crane Operations

On Gulf of Mexico platforms, cranes handle crew transfers, equipment lifts, and cargo swings between supply vessels and the platform deck. Personnel basket transfers carry workers between the vessel and the platform. A crane malfunction during a basket transfer can drop workers into the water or onto the vessel deck.

OSHA maritime standards govern crane operations in different settings. 29 CFR Part 1918 covers longshoring operations. 29 CFR Part 1915 covers shipyard employment. These standards require load testing, operator certification, and rigging inspections. When employers skip these requirements, workers get hurt.

Liability and Evidence in Crane Accidents

Crane accidents create multiple potentially liable parties: the crane owner, the operator, the maintenance contractor, and the vessel or platform operator. Identifying all responsible parties is central to an offshore accidents claim.

The key is preserving maintenance and inspection records before they disappear. Crane inspection logs, load test certificates, and operator training files are routinely overwritten on schedule. Morris & Dewett sends preservation demands within the first days of engagement to lock down this evidence.

Slip, Trip, and Fall Accidents on Vessels and Docks

Slips and falls are the most common category of maritime injury by frequency. Wet and oily deck surfaces, poorly maintained walkways, inadequate non-skid coatings, and debris on work surfaces cause injuries every day on Louisiana vessels and docks.

Falls from ladders and stairways account for a significant share. So do falls between the vessel and the dock during gangway transfers. The vessel moves with wave action and the gap between ship and pier shifts unpredictably. Weather compounds the problem. Rain, ice, and sea spray create slick surfaces that standard housekeeping cannot always control.

unseaworthiness

A legal doctrine under general maritime law holding that a vessel owner has an absolute duty to provide a ship that is reasonably fit for its intended purpose. This includes safe walking surfaces, working equipment, and a competent crew. The standard is strict liability, not negligence.

The unseaworthiness doctrine is critical here. A vessel owner has an absolute duty to maintain a ship that is reasonably fit for its intended purpose. That includes safe walking surfaces. If a deck condition made the vessel unreasonably dangerous, the owner is liable regardless of negligence. This is a strict liability standard. A Jones Act negligence claim and an unseaworthiness claim are separate causes of action with different proof requirements.

Falls from Heights

Falls from heights on maritime worksites cause spinal fractures, traumatic brain injuries, internal organ damage, and fatalities. The work environments where these falls occur include vessel masts and rigging, superstructure maintenance, shipyard scaffolding, and offshore drilling derricks.

OSHA maritime fall protection standards require specific safeguards. 29 CFR 1915.159 covers shipyard employment fall protection. 29 CFR 1918.85 addresses fall protection in longshoring. These standards mandate guardrails, safety nets, and personal fall arrest systems at specific heights.

When fall protection equipment is absent, improperly maintained, or the wrong type for the job, the employer bears responsibility. Fall protection inspection records and equipment maintenance logs often reveal that the employer knew the equipment was deficient before the accident occurred. Morris & Dewett sends preservation demands for fall protection records within the first days of engagement because this evidence has a short shelf life.

Machinery and Equipment Injuries

Vessels and offshore platforms operate heavy machinery in confined, moving environments. Winches, capstans, conveyors, and powered deck equipment create entanglement, amputation, and crush injury hazards. Engine rooms add high-pressure steam lines, rotating machinery, and enclosed spaces where a single malfunction can be catastrophic.

Vessel and Platform Equipment

Lockout/tagout procedures prevent equipment from being energized while a worker is performing maintenance. When these procedures fail or are not followed, workers get caught in machinery that starts without warning. This is a recurring cause of amputations and crush injuries on vessels and offshore oil rigs.

Engine rooms present concentrated hazards. High-pressure steam lines, rotating shafts, and auxiliary generators operate in tight spaces with limited escape routes. A steam line rupture in an engine room causes severe burns in seconds. These injuries are preventable when maintenance schedules are followed.

Shipyard Machinery

Shipyard workers face hazards from welding equipment, grinders, presses, and heavy fabrication tools. The combination of industrial equipment and the maritime environment creates risks that standard factory settings do not have. A shipyard worker operating a grinder on a vessel hull works in a confined space with limited ventilation and restricted movement.

Shipyard injuries fall under OSHA maritime standards (29 CFR Part 1915) and may be covered by the LHWCA rather than the Jones Act. The worker’s location and job duties determine which statute applies. This classification affects both the available benefits and the burden of proof required.

An OSHA violation and an actionable legal claim are not the same thing. OSHA violations are evidence, but they do not create a private right of action by themselves. The safety violation must be connected to the legal theory that applies to your status as a worker.

Fires, Explosions, and Chemical Exposures

Maritime fires and explosions cause some of the most severe injuries in the industry. Fuel fires on vessels, offshore platform blowouts, well control incidents, and barge explosions during cargo loading and unloading are all common scenarios in the Gulf of Mexico drilling corridor.

Acute Fire and Explosion Injuries

Tank vessels and barges carrying petroleum products present explosion risks during cargo transfers. Vapor accumulation in cargo tanks, static discharge, and equipment sparks can ignite volatile cargo. Offshore platform fires start from blowouts, equipment failures, and hydrocarbon leaks.

The injuries include severe burns, blast injuries, smoke inhalation, and traumatic amputations. Workers caught in an offshore platform fire may face evacuation over open water, which compounds the initial injuries with fall and drowning risks. Burn treatment often requires specialized facilities and months of care.

Chemical Exposure and Long-Term Health Effects

hydrogen sulfide

H2S. A toxic gas commonly encountered in oil and gas operations, produced naturally during drilling and petroleum processing. Exposure at low concentrations causes respiratory irritation. At high concentrations, H2S can cause immediate loss of consciousness and death. OSHA sets the permissible exposure limit at 20 ppm.

Chemical exposures on maritime worksites include benzene, hydrogen sulfide (H2S), drilling fluids, and cargo fumes. Long-term exposure to asbestos on older vessels causes mesothelioma and other respiratory diseases.

These claims involve different proof requirements because the injury develops years after the exposure. You need medical records showing the exposure history, employment records documenting which vessels or platforms you worked on, and expert testimony connecting the exposure to the diagnosis. The discovery process for toxic exposure cases is longer and more complex than for acute accident cases.

Toxic exposure claims require industrial hygiene expert testimony and medical causation evidence that is different from a standard accident case. Morris & Dewett works with oil and gas industry experts who understand Gulf of Mexico drilling operations and the chemical hazards specific to offshore work.

Mooring and Line Handling Accidents

Mooring accidents are among the most violent injuries in the maritime industry. When a mooring line under tension breaks, the snap-back creates a lethal arc that can amputate limbs, crush bones, or kill instantly. The force involved is enormous.

Mooring operations happen daily at Louisiana ports including the Port of South Louisiana, Port of New Orleans, Port of Baton Rouge, and Port of Lake Charles. Workers handle wire rope, synthetic lines, and combination mooring systems under conditions that require precise coordination between vessel and shore crews.

Contributing factors include worn lines that have not been inspected or replaced, improper winch operation, and communication failures between the vessel crew and the shore gang. The Oil Companies International Marine Forum (OCIMF) publishes Mooring Equipment Guidelines that set industry standards for line inspection, snap-back zone marking, and safe mooring procedures. When an employer ignores these standards, workers pay the price.

The vessel’s mooring equipment inspection records and the employer’s line replacement logs show whether the line that broke was past its service life or had visible damage that was ignored.

Commercial Diving Accidents

Louisiana’s commercial diving industry is tied directly to offshore oil and gas infrastructure. Saturation divers and surface-supplied divers work on Gulf of Mexico platforms, pipelines, and subsea installations in conditions that most people cannot imagine.

Decompression sickness

Also called “the bends.” A condition caused by dissolved gases (primarily nitrogen) forming bubbles in the blood and tissues during ascent from depth. Symptoms range from joint pain and rashes to paralysis, stroke, and death. Treatment requires immediate recompression in a hyperbaric chamber.

Decompression sickness is the signature risk. Divers who ascend too quickly or whose decompression schedules are miscalculated develop gas bubbles in their blood and tissues. The results range from joint pain to permanent neurological damage, paralysis, and death. Arterial gas embolism, hypothermia, and equipment failures including breathing gas supply interruption and umbilical entanglement add to the hazard profile.

OSHA commercial diving standards (29 CFR Part 1910 Subpart T) and the Association of Diving Contractors International (ADCI) consensus standards set the safety requirements. These cases require expert witnesses who understand dive physiology, decompression tables, and the specific equipment involved. This is a narrow field where general personal injury experience is not enough.

Man Overboard Incidents

Falls overboard from vessel decks, gangways, and working platforms happen more often than most people realize. Contributing factors include missing or inadequate guardrails, poor lighting, crew fatigue, and rough seas.

In Gulf of Mexico winter waters, hypothermia onset begins within minutes. Rescue response time is the critical survival factor. The U.S. Coast Guard requires immediate reporting of man overboard incidents, and vessels must have retrieval procedures and equipment in place.

The legal analysis of a man overboard case focuses on whether the vessel was seaworthy. Missing guardrails, inadequate lighting in work areas, and failure to enforce safety procedures all go to the question of whether the vessel owner maintained a reasonably safe ship. Secondary injuries during rescue operations may also be compensable.

The vessel’s safety equipment inspection logs show whether guardrails, lighting, and retrieval equipment met regulatory standards at the time of the accident. If the vessel’s safety equipment was deficient, the unseaworthiness claim strengthens significantly.

Which Maritime Law Applies to Your Accident

The single most important question in any maritime injury case is which law applies. The answer determines your rights, your deadline to file, and who you can hold responsible.

Jones Act (Seamen)

Jones Act

A federal statute (46 U.S.C. 30104) that allows seamen to sue their employers for injuries caused by negligence. To qualify, a worker must spend approximately 30% or more of their work time in service of a vessel or fleet of vessels. The Jones Act provides a three-year statute of limitations and uses pure comparative fault.

Comparative Fault

A legal rule that reduces your recovery by your percentage of fault. In Louisiana, if you are 51% or more at fault, you recover nothing. If you are 50% or less at fault, your damages are reduced proportionally.

The Jones Act (46 U.S.C. 30104) covers seamen. To qualify, you must spend roughly 30% or more of your work time in service of a vessel or fleet. The Jones Act gives you the right to sue your employer for negligence and provides a three-year statute of limitations. It uses pure Comparative Fault. There is no threshold bar. Even if you are 90% at fault, you recover 10% of your damages. Read more about Jones Act claims.

General Maritime Law (Unseaworthiness and Maintenance and Cure)

Seamen also have claims under general maritime law for unseaworthiness and maintenance and cure. Maintenance and cure is an unconditional obligation. Your employer must pay your living expenses and medical bills regardless of who was at fault.

LHWCA (Harbor Workers)

LHWCA

Longshore and Harbor Workers’ Compensation Act (33 U.S.C. 901). A federal workers’ compensation statute covering maritime workers who are not seamen, including longshoremen, harbor workers, ship repairers, and shipbuilders. Benefits are no-fault but limited to scheduled amounts. Injured workers may also have third-party negligence claims.

The LHWCA (33 U.S.C. 901) covers maritime workers who do not qualify as seamen. This includes longshoremen, harbor workers, ship repairers, and shipbuilders working on navigable waters or in adjoining areas. LHWCA claims are workers’ compensation claims with scheduled benefits, but you may also have a third-party negligence claim against someone other than your employer.

OCSLA and State Law

The Outer Continental Shelf Lands Act extends state workers’ compensation to workers on fixed platforms on the outer continental shelf. State law may apply to accidents in Louisiana territorial waters depending on your worker status.

Deadlines and Comparative Fault

Prescriptive Period

Louisiana’s term for statute of limitations. The legal deadline to file a lawsuit. For personal injury, it is two years from the date of injury under La. C.C. Art. 3493.1 (effective July 1, 2024).

Louisiana’s two-year Prescriptive Period under La. C.C. Art. 3493.1 (effective July 1, 2024) applies to state-law claims only. Jones Act claims have a three-year federal deadline. LHWCA claims must be reported to the employer within 30 days and filed within one year.

Louisiana’s 51% comparative fault bar under La. C.C. Art. 2323 (effective January 1, 2026) applies to state-law claims. If you are 51% or more at fault, you recover nothing under Louisiana state law. The Jones Act uses pure comparative fault with no threshold bar.

The Death on the High Seas Act (DOHSA, 46 U.S.C. 30301) applies to fatal accidents occurring more than three nautical miles from shore. DOHSA limits recoverable damages to pecuniary losses only. Whether DOHSA applies to a fatal offshore accident is critical to evaluating the case.

Which laws apply to your accident determines the filing deadline and whether Louisiana state law or federal maritime law controls the fault analysis, and it turns on your seaman legal rights and worker status.

What to Do After a Maritime Accident in Louisiana

The steps you take immediately after a maritime accident affect your legal options. Here is what matters.

Report the accident to the vessel master or supervisor immediately. Federal regulations require prompt reporting, and failure to report can be used against you later. Get the report in writing. If the employer provides an incident report form, fill it out yourself or review what they write before signing.

Document the scene if you can. Photos of the conditions, the equipment involved, and your injuries are evidence that does not exist unless you create it. Get the names and contact information of anyone who witnessed the accident.

Seek medical attention as soon as possible. If you are on an offshore platform or vessel, you may need medical evacuation. Tell the medical provider exactly how you were injured and describe all symptoms.

Do not give a recorded statement to the employer’s insurance adjuster without consulting an attorney. These statements are used to limit your recovery. You are not required to give one immediately.

maintenance and cure

An unconditional obligation under general maritime law requiring the employer of an injured seaman to pay daily living expenses (maintenance) and all reasonable medical expenses (cure) until the seaman reaches maximum medical improvement. This obligation exists regardless of who was at fault for the injury.

Your maintenance and cure rights begin at the moment of injury. If you are a seaman, your employer owes you living expenses and medical bills from day one regardless of fault. If your employer denies or delays these payments, that is a legal violation. Morris & Dewett demands maintenance and cure payments within the first week of engagement because delays compound the financial pressure on injured workers.
