Offshore Vessel Injury Lawyer for Liftboat, Supply Boat and Crew Boat Accidents

You do not need to know the vessel's Coast Guard classification, your own legal status, or which company technically owned the boat before you reach out. A doctor's appointment you had to fight for, a paycheck that has stopped or shrunk, and a stack of company paperwork you are not sure whether to sign is a normal starting point. A claim review works from what you know: the name of the boat or a plain description of it, who you worked for, the day you were hurt, and what you were doing when it happened.

Evaluating a possible claim starts with those facts, not with the vessel's name. A liftboat, a supply boat and a crew boat each raise different operational questions, and the same vessel can produce different legal positions for two workers standing next to each other. For our broader offshore representation, including rigs, platforms and injuries in the Gulf generally, see offshore injury claims.

Being Injured on an Offshore Vessel Does Not Automatically Make You a Jones Act Seaman

The Jones Act, 46 U.S.C. § 30104, gives a qualifying seaman the right to sue an employer for negligence. The word that matters is qualifying. Being aboard a vessel when you were hurt, even one you rode every hitch, does not by itself make you a seaman. Under Chandris, Inc. v. Latsis, 515 U.S. 347 (1995), seaman status turns on whether your duties contributed to the vessel's function or mission and whether you had a connection to a vessel or fleet that was substantial in both duration and nature. The Fifth Circuit, whose decisions control in federal courts in Louisiana, has refined that inquiry further. The analysis looks at your assignment history and the character of your work, not your job title and not the accident location.

Here is why that matters on a crew boat in particular.

Hypothetical. A crew boat leaves Port Fourchon at 4 a.m. carrying a relief crew to a production platform. Aboard are a deckhand who has been assigned to that boat for eleven months and a production operator who rides the same boat every two weeks to reach the platform. A wave hits during a rough transit and both men are thrown against a bulkhead and injured.

The deckhand's regular assignment to the vessel is the kind of fact that supports a seaman-status argument. The operator's assignment is to the platform; the boat is his ride. Those two workers may end up with different remedies against different parties even though the same wave hurt them both. Neither is automatically covered or automatically excluded by these facts alone. Each needs an individualized review of duties, assignment records and how the trip was run.

If you are a qualifying seaman, three distinct routes may be open to you, and they are analyzed separately:

• Jones Act negligence against your employer, based on unsafe orders, methods, staffing, training or equipment. See Jones Act claims against an employer.
• Maintenance and cure, the employer's obligation to pay living expenses and medical care during recovery, which does not depend on proving fault. Covered below and in detail on maintenance and cure benefits.
• Unseaworthiness, a claim against the vessel owner when the vessel, its gear or its crew was not reasonably fit for its intended use. See claims involving an unseaworthy vessel.

If you do not qualify as a seaman, that is not the end of the analysis. A transported platform worker, or someone whose vessel connection was too limited, may instead fall under the Longshore and Harbor Workers' Compensation Act, either directly or through its extension to the Outer Continental Shelf under 43 U.S.C. § 1333. Covered workers injured through a vessel's negligence may also have a separate claim under Section 905(b) of that Act, 33 U.S.C. § 905(b). These are conditional routes with their own coverage rules and exclusions. See Longshore Act coverage and Section 905(b) vessel negligence claims.

The status tests, the percentage guidelines and the exclusions are explained on our page about whether you qualify as a Jones Act seaman. The practical point here is simpler: tell us what you actually did aboard and how long you had been doing it, and let the analysis follow.

Liftboat Injuries: Was the Vessel Underway, Elevating or Working on Its Legs?

A liftboat is a self-propelled vessel with legs, usually three, that can be lowered to the seabed to raise the hull out of the water. Afloat, it moves under its own power. Elevated, it is designed to work from its legs, with a crane, deck space and accommodations, for well intervention, platform maintenance, construction and decommissioning in relatively shallow water. Elevation does not by itself guarantee stability; the vessel's operating limits, the seabed and the jacking operation all bear on whether the vessel was safe to work from. A liftboat is not a jack-up drilling rig. Jack-ups are mobile offshore drilling units, are typically towed to location, and exist to drill. If you were hurt on a drilling rig or drillship, that is a different vessel family with its own page: offshore rig and drillship injuries.

Because a liftboat lives in three operating states, the first question after a liftboat injury is what the vessel was doing at that moment.

Transit

When a liftboat is underway with its legs raised, it is a relatively top-heavy hull with a tall structure above the waterline. The questions in a transit incident are about the decision to sail and the condition of the vessel when it did: What weather forecasts and warnings did the operator have, and when? What was the loading condition on deck? How was cargo stowed and secured? What did the vessel's own operating limits say about sea state and wind for transit? Were the legs, jacking system and watertight closures in the condition they needed to be in?

Elevating and lowering

Jacking a liftboat up or down is a controlled operation with its own risks: uneven seabed, leg penetration, punch-through, and the mechanical condition of the jacking gear. Questions here include who was on the controls and how they were qualified, whether the seabed was surveyed or known, whether preload procedures were followed, what the operating manual permitted for the conditions, and what the jacking and leg records show.

Elevated work

Once on its legs, a liftboat is a work site. Injuries here may involve the crane, the cargo deck, gangways or bridges to an adjacent platform, and the coordination between the liftboat crew and the third-party workers who came out to do a job. The questions shift to lifting plans, communications between the crane operator and riggers, deck housekeeping, work permits and job safety analyses, and who was directing the work.

The Coast Guard regulates liftboats under rules that include the liftboat-specific provisions of 46 CFR Part 134, which address matters such as operating manuals and operating limitations. Which requirements applied to a particular vessel depends on its certification, its size and the date of the incident, so that has to be verified against the vessel's records rather than assumed.

Two cautions. First, these are investigative questions. Identifying them does not mean the accident resulted from negligence; that has to be proven with evidence. Second, the vessel's position at the instant of your injury does not settle your legal status. Whether an elevated liftboat remains a vessel in navigation for Jones Act purposes, and whether you were a seaman aboard it, are legal questions that require attorney analysis of the vessel's history and your assignment. See whether you qualify as a Jones Act seaman.

Supply Boat and OSV Injuries: Cargo, Deck Work and Stationkeeping

"OSV" stands for offshore supply vessel. "Supply boat" and "platform supply vessel" describe the same broad category of vessels that carry deck cargo, liquid mud, fuel, water and equipment between shore bases and offshore installations. "Workboat" is a broader term that takes in many other vessel types as well. Not every colloquial name lines up with a regulatory classification, and the Coast Guard's OSV rules in 46 CFR Part 125 and the rest of Subchapter L apply based on the vessel's certification, not its nickname. The actual certificate has to be checked before anyone says a rule applied.

Three situations recur in supply work. Deck cargo is moved by shore cranes, platform cranes and the vessel's own gear, then secured for a transit that may cross rough water; loads can shift, securing can fail, and a crane operator on the platform may not be able to see the deck. Working alongside a platform means fenders, lines, backloading and people moving on a deck that is rising and falling with the swell. And holding position next to a platform is done either with manual control from the bridge or, on many larger OSVs, with a dynamic positioning system; not every supply boat has DP, and not every DP vessel records the same data. An injury review connects the task you were doing to the vessel's movement and to who was controlling the operation. The table below summarizes the questions and the evidence that may correspond to each. Whether a particular record exists depends on the vessel and its operator.

Loading and unloading injuries in general, mooring and line-handling injuries, and specific accident mechanisms are covered in more depth on their own pages: loading and unloading injuries, line-handling and mooring injuries and offshore accident and injury scenarios.

Crew Boat Injuries: Rough Transit and Transfers Require More Than a Passenger List

Crew boats, sometimes written "crewboats," carry workers between shore and offshore installations, often at speed and often in weather that the workers aboard did not choose. If you were hurt riding to work, boarding the boat, or transferring from the boat to a platform, your injury deserves review even if you have never thought of yourself as a maritime worker.

Two questions run in parallel in every crew boat case. The first is your work relationship: who employed you, what you were assigned to, and whether you were vessel crew or a passenger on the way to your actual job. The second is how the trip or transfer was run. A transported worker is not vessel crew because the injury happened aboard, and a platform worker does not lose a claim because he was "just a passenger." Both questions have to be answered on the facts.

Three settings raise different questions, and the evidence differs for each.

Transit

A crew boat pounding through a head sea can throw seated passengers, and a poorly secured seat, a wet deck or an unannounced speed change makes it worse. The questions are about the decision to run in those conditions, the speed chosen, the forecast and observed weather, whether passengers were warned or told to remain seated, and the condition of the seating and handholds.

Boarding at the dock

Boarding injuries may involve the gangway, the gap between vessel and dock, lighting, and whether anyone was assisting. Who owned and controlled the dock matters as much as who ran the boat.

Transfer offshore

Getting from a moving crew boat to a fixed platform is done several ways: a swing rope from a boat landing, a personnel basket lifted by the platform crane, a gangway or bridge, or, on some installations, a motion-compensated transfer system. Each method has its own procedures and limits. When a worker is injured in a transfer, the questions are which method was used, whose procedure governed it, what the sea state and vessel motion were, who gave the instruction to transfer, and how the vessel crew and platform crane operator or deck crew communicated. The exact point of transfer can matter legally as well as factually. A worker who has stepped onto the platform and one who is still on the boat's deck may be in different positions, and the vessel crew and the destination personnel have different roles. None of that assigns liability automatically; it defines what has to be investigated.

A crew boat may be certificated under different Coast Guard rules than a supply vessel, so the regulations that governed the particular boat have to be verified rather than borrowed from OSV requirements. For claims arising on the platform itself, see offshore platform injuries. For the vessel-negligence route available to some covered non-seamen, see Section 905(b) vessel negligence claims, and for the status questions, whether you qualify as a Jones Act seaman.

Who Controlled the Vessel, the Equipment and the Work When You Were Hurt?

On paper, an offshore vessel injury looks simple: you worked for a company, you were hurt on a boat, the company should answer. In practice, several companies can touch a single trip. Your employer may be a labor contractor. The boat may be owned by one company, operated by a second, and chartered to the oil company that owns the platform. The crane may be maintained by a fourth. The job you were sent to do may have been directed by a contractor's supervisor who was not on anyone's crew list.

Responsibility follows duty and evidence, not payroll. The investigation separates the roles:

• Your employer — instructions, training, staffing levels, work methods and the decision to send you into the conditions you faced.
• The vessel owner or operator — the condition of the hull, gear and crew; maintenance; manning; operating limits and whether they were honored.
• The charterer — depending on the charter terms, who set the schedule, directed cargo and personnel movements, and pressured the vessel to work in marginal conditions.
• Contractors and equipment companies — cranes, rigging, transfer systems and other gear that was supplied, inspected or maintained by someone other than your employer.

These map onto distinct legal analyses. A Jones Act negligence claim is against the employer. An unseaworthiness claim is against the vessel owner for the vessel's condition. Third-party negligence and product claims are against whoever else breached a duty. One incident can involve more than one of these, and it can also involve none, which is why investigation comes before any opinion about what a case is worth. For the broader frameworks, see third-party maritime injury claims, contractor and premises negligence, maritime product and equipment liability and claims involving an unseaworthy vessel.

Two explanations you may hear early are that you caused your own injury, or that the weather was unavoidable. Treat both as claims to be tested, not conclusions. A worker's alleged fault is measured against the instructions he was given, the conditions he was placed in and the alternatives that were available to the people in charge. "Unavoidable weather" invites the questions of what forecasts were available, what the vessel's own limits said, and who made the call to proceed.

Hypothetical. A supply boat is backloading equipment from a platform in building seas. The platform crane operator is employed by the platform owner. The boat's captain, employed by the vessel operator, radios that the deck is getting too lively. A contractor supervisor on the platform asks for one more lift to finish the job. A deckhand employed by a crewing company is struck when the load swings.

The deckhand's employer, the vessel operator, the platform owner and the contractor each made decisions or controlled equipment that could bear on how this happened. Which of them, if any, is legally responsible depends on their actual duties, the evidence of what was said and done, and the legal framework that applies to the deckhand. Nothing about the labels answers that.

After an Offshore Vessel Injury: Get Care, Report Accurately and Preserve What You Have

Your health comes first. If you need treatment, get it, and do not wait to speak with a lawyer before seeking urgent care. Everything below assumes that.

Reporting

Report the injury to your supervisor or the vessel's master as your employer requires, and report it accurately. If you do not know why something happened, say so. Do not guess at a cause to fill in a form, and do not sign an account you know to be incomplete or wrong. A report that honestly records uncertainty is far better for you than one that confidently records something that turns out to be inaccurate.

Information you can safely keep

You are entitled to keep your own records. Write down or hold onto:

• The vessel's name, or a description if you do not know it, and the company you understood to be operating it
• Your employer's name and, if different, the company that hired you out
• The date and approximate time of the injury
• What you were doing and what the vessel was doing: underway, alongside, elevated, jacking, transferring, loading
• The weather and sea conditions as you experienced them
• Names or descriptions of anyone who saw what happened or who was giving instructions
• Copies of anything you were given or asked to sign, including incident reports and medical forms
• Your medical records, discharge instructions, work restrictions and receipts
• Your own photos of the scene or your injuries, if you took them lawfully at the time

Do not remove company records from the vessel, access systems you are not authorized to use, or alter anything. That would hurt you, not help you.

Records counsel requests

Operating records belong to the vessel operator and other companies, and they are obtained through preservation demands and, if necessary, the discovery process. Not every vessel carries the same equipment or keeps the same records, which is one reason a prompt preservation request matters. Depending on the vessel and the incident, the records worth seeking include:

Releases and insurer statements

Before you sign a release, settlement or any document that waives rights, have it reviewed. Before you give a recorded statement to an insurer or claims adjuster for the company or the vessel, get advice. This is different from your obligation to report the injury to your employer, which you should meet. It is the adjuster's recorded interview, and the paper that follows it, that deserves a lawyer's eyes first.

Deadlines

Deadlines depend on the claim. A maritime negligence suit, a Longshore Act notice and claim, and a claim asserted in a vessel owner's limitation-of-liability proceeding each run on different clocks, and some notice periods are short. There is no single number that fits every offshore vessel claim. Get your situation reviewed promptly so the applicable deadlines can be identified. For the Longshore side, see LHWCA filing deadlines; for our broader offshore guidance, offshore injury claims.

Medical Bills and Missed Work: The Available Route Depends on Your Status

Before fault, there is a more immediate question: how the bills get paid and how the household keeps going while you cannot work. The answer depends on the status analysis discussed above, and it is separate from proving anyone was negligent.

If you qualify as a seaman and were injured or became ill while in the service of the vessel, your employer generally owes maintenance and cure: a daily living allowance and payment of reasonable medical care until you reach maximum medical improvement. This obligation does not depend on fault. It is owed whether or not your employer did anything wrong, and it is distinct from the damages you might recover in a Jones Act or unseaworthiness case. The obligation is broad but not unlimited; certain defenses and exceptions can apply, and eligibility is explained on maintenance and cure benefits. If payments have been late, cut off or never started, see denied or terminated maintenance and cure.

If you are covered by the Longshore Act, directly or through its Outer Continental Shelf extension, the framework is different: compensation benefits and medical treatment provided by the responsible employer or its insurer, as applicable, with their own procedures and rates. See LHWCA benefits and compensation.

Neither set of benefits should be assumed from the vessel type alone, and neither is a substitute for a full evaluation of a damages claim. In a vessel injury review, the issues to raise include:

• Treatment that has been delayed, denied or steered to a particular clinic
• Maintenance or compensation payments that stopped, arrived late or were reduced without explanation
• Work restrictions from your doctor and whether the company has honored them
• Whether you can realistically return to the same vessel duties, and what your doctor says about that

Your own medical and work evidence carries these issues. Settlement ranges and benefit figures are not published on this page because they mean nothing without the facts of your case. For the wider picture of what injured offshore workers may be entitled to, see offshore injury rights and compensation.

Legal and Vessel-Safety Sources Behind This Guidance

The statutory and status explanations on this page rest on the following primary authorities. Each is identified with the proposition it supports so you can see where the statements come from and what they do not say. Maintenance and cure and unseaworthiness arise under general maritime law rather than a single statute; their governing rules are addressed on maintenance and cure benefits and claims involving an unseaworthy vessel.

A few things these sources do not do. Coast Guard regulations tell you what a certificated vessel was required to have and do; they do not tell you whether a given vessel complied, which is a matter of that vessel's records. National Transportation Safety Board and Coast Guard casualty investigations can be valuable factual research on how liftboats, supply vessels and crew boats fail, but an agency's probable-cause finding is a safety conclusion, not a determination of civil liability, and the two are governed by different rules of evidence. Nothing on this page describes any matter The Young Firm handled or implies our involvement in any public casualty.

This page is general information about how these claims are analyzed. It is not a determination of your seaman status, your coverage or anyone's liability, and it is not legal advice for your situation. Those require review of your actual assignment records, the vessel's records and the facts of the incident. For the underlying frameworks, see Jones Act claims against an employer and Longshore Act coverage.

Talk With The Young Firm About Your Vessel, Assignment and Injury

If you were hurt on a liftboat, an offshore supply vessel or a crew boat, call our New Orleans office or send a message through this site and tell us what happened. Start with four things: the vessel's name or a description of it, the company you worked for, the date you were injured, and what you and the vessel were doing at the time. If you know how long you had been assigned to that boat and whether you were crew or a passenger, tell us that too. If you do not know, say so. Uncertainty about your status is a reason to call, not a reason to wait.

You do not need documents to reach out. If you have an incident report, medical records, a crew list, a manifest or anything you were asked to sign, we will want to see it, but missing paperwork does not prevent a conversation. Most of the records that matter are held by the companies, and getting them preserved is part of what counsel does.

Contacting the firm to discuss your situation does not by itself create an attorney-client relationship. We will explain how representation works, including the terms of any engagement, when we talk.

If you are reading this because someone in your family did not come home from a liftboat, a supply boat or a crew boat, we are sorry. The law that applies to a fatal offshore accident is different in important ways from what is described here, and your family's rights are addressed on offshore wrongful death. You are welcome to contact us directly as well; you do not have to sort out which page applies before you do.
