COMMERCIAL DIVER DEATH DIVER’S UMBILICAL BECOMES ENTRAPPED IN PROPELLER OF DSV
COMMERCIAL DIVER DEATH
DIVER’S UMBILICAL BECOMES ENTRAPPED IN PROPERLOR OF DSV
Root Causes of Incident:
- Inexperienced Supervisor and Crew
- No JSA
- Poor Planning of Project
- Improper selection of dive vessel
- Malfunctioning vessel gear.
Commercial diver, JC, age 31, died when his umbilical become entrapped in the propeller of the jack-up vessel as he was working in shallow waters off the coast of Louisiana.
Alton Hall and Bobby Delise were asked to represent the widow of JC against his employer and the operator and owner of the jack-up vessel. Litigation was filed in the United States District Court for the Eastern District of Louisiana.
This case arose from a tragic July 2005 accident in which 31 year old JC was killed when his umbilical hose was caught in the prop of the vessel from which he was diving, dragging him to his death. At the time JC was employed as a commercial diver for a Louisiana diving contractor, diving from a “backup jack-up”. The job in question took place in territorial waters offshore Louisiana. The project, as it developed over the course of the day, was to locate a leak in a pipeline hand jet (uncover) a portion of the pipeline in order to trace the line and determine if it could be lifted and repair the leak onboard the vessel. Due to crossing lines the project manager directed that the damaged portion of the line be cut and a clamp installed. This required that the repaired section be replaced utilizing divers and the vessel’s crane.
The vessel being used was a unique vessel in that not only was it a jack-up having three legs that are spudded into the ocean floor to provide a stable work platform, but its configuration is such that the wheelhouse is at the bow of the vessel hence the name “backup jack-up”. Unlike conventional jack-up vessels, the props of the vessel being used are located at the opposite end of the vessel from the wheelhouse.
At the time of the incident, the vessel was positioned with the stern adjacent to the platform riser to be repaired. This required the divers to enter and exit and work in proximity to the vessel’s props. The diving contractor’s dive supervisor testified that he was unaware that they (the divers) were working near the props, admittedly confused by the reverse configuration of the vessel. During the actual repair of the riser, it was necessary to utilize one of the vessel’s two cranes to lift and place a repaired section of the riser. The diver was dispatched into the water to guide the placement of the riser. Use of the crane required that the port engine be utilized which allowed the port prop to spin.
The vessel was not, as is required by the vessel owner’s operations manual, completely jacked out of the water during operations. This was significant in that it placed the props in the water where due to limited visibility created by the murky water they could not be visualized and allowing the port prop to draw water, and in this case the diver’s umbilical into it.
The vessel’s port engine was operating at the time of the accident in order to supply power to the crane. Although the vessel’s transmission was allegedly in neutral, a faulty transmission allowed the port prop to spin at a relatively slow revolution but with high torque. This “free spinning” is not uncommon on jack-up vessels where the cranes and other equipment are operated by the vessel’s engines.
JC was in shallow water guiding one end of the repaired riser, the other end being lifted by the vessel crane and guided by a crewman in the man lift. JC’s tender was on his first job in the business. Shortly after operations began workers on deck saw the umbilical jerked from the tender’s hand and later heard the engine “bog” and “thumps” under the vessel as the prop apparently struck JC’s dive helmet.
The dive supervisor having lost communications with JC, left the dive station and jumped into the water where he found JC dead and entangled in the vessel props.
Subsequent investigation by Delise and Hall found that the vessel transmission was faulty allowing the prop to spin even though the transmission was allegedly in neutral.
Delise and Hall’s Representation of Diver’s Family
Delise and Hall argued that the death of JC was the result of the diving contractor’s negligence and the unseaworthy condition of the DSV.
DIVING CONTRACTOR NEGLIGENCE
Delise and Hall summarized its allegations of error by the diving contractor in its:
- Selection of inexperienced dive crew;
- Selection of procedures which placed divers in an ultra dangerous work site;
- Failure to follow diver contractor’s policies and procedures established by diving contractor’s Safe Diving Practices Operations Manual;
- Allowing diving operations to commence without implementing safety procedures;
- Failure to inspect the vessel and equipment to ensure that diving operations could be conducted in safe manner; and
- Failing to employ a task specific JSA.
Delise and Hall argued that the dive supervisor’s decision to conduct diving operations in the vicinity of the props placed JC in a very dangerous work site. During sworn testimony the supervisor testified that he was confused by the configuration of the vessel as a “backup” or “reverse” jack-up and not realizing that the props were at the end of the vessel from which the divers were working.
Delise and Hall also argued that the supervisor was inexperienced and in fact had never received certification as a supervisor.
Delise and Hall also argued that the support crew’s inexperience played a significant role in JC’s death. This job was the first job offshore for the tender and his second day of employment with the company having graduated from dive school the same week. Evidence was established that the tender let out approximately three times too much umbilical hose allowing the hose to slack and be drawn into the prop.
Delise and Hall also established that there existed no Job Safety Analysis prepared prior to the commencement of the dive, a violation of the ADCI Consensus Standards and the diving contractor’s own safety manual.
Delise and Hall summarized its allegations of error by the vessel owner in its:
- Failure to follow its policies and procedure for operations of a jack-up;
- Utilizing a vessel that had mechanical problems which placed the diver in peril;
- Providing an incompetent captain and crew for conducting diving operations; and
- Failing to coordinate operations with subcontractors.
Delise and Hall argued that the vessel was grossly unseaworthy. Absent the failure of the vessel’s transmission this accident would not have occurred.
Delise and Hall clearly established that Maritime Law provides that a vessel with a faulty transmission is not “reasonably fit” and thus the vessel owner/operator had no defense in the litigation.
Making matters more deadly was the fact that the operator of the vessel failed to follow its own procedures in jacking the vessel out of the water, did not advise the dive crew of the location of the props, left the controls unattended while the Captain operated the crane and positioned the vessel such that the divers had no real choice but to dive from the stern. All testimony indicated that this “free spin” phenomenon is common to jack-up vessels.
All the relevant witnesses testified as to having observed it previously on other vessels and significant to the knowledge of Allied with regard to limitation, they knew that the USCG inspected for “free spin” and had a similar transmission failure on a sister vessel. The point being that the vessel owner was aware of the potential danger and failed to warn anyone of such or follow any type of lockout/tag out system.
Delise and Hall convinced the diving contractor and the vessel owner’s insurance carriers to resolve the case during mediation. Because of the serious of the settlement terms the amount of resolution paid to JC’s widow is confidential.
Several months prior to the death of the diver a GOM diving contractor, not manned, equipped or experienced in ship husbandry, decided to open a ship husbandry division through its subsidiary. This special division would act a mobile “SWAT team” of divers, supervisors and support crew to travel on short notice to clean ships in a geographical swath from the East Coast to the West Coast.
Shortly after the subsidiary’s formation the diving company contracted with a foreign vessel’s agent to clean the hull of a supertanker moored off the coast of Galveston. At the time of his death the diving contractor directly employed MS.
From the onset of the project the job the diving contractor’s effort to complete the project was an abysmal failure. After working for 27 hours straight, giving the crew of divers and tenders no rest, the on-site diving supervisor advised his superiors onshore and the captain of the supertanker that he had to suspend operations and return to harbor to secure more experienced and rested divers. A call was made for more divers and MS was sent offshore.
On the morning of MS’s death the diving contractor was faced with the task of completing the scouring of approximately 40% of the hull of the supertanker. The company, because of its inept planning, was severely behind schedule and matters would only worsen as the day progressed.
Date of Diver’s Death
On the date of the diver’s death diving operations commenced at 05:24 with Dive #1, a dive that was aborted because of a malfunction in the diver’s helmet. During dive #2 some work was completed but it too was aborted because of equipment failure. Dive #3 was short in nature with very little work being completed.
MS’s dive – the dive when he was killed - was scheduled to last 200 minutes at a depth ranging from 30-40 feet below the surface as he guided the hydraulically powered dual head rotary device along the hull of the supertanker. All of the images seen by MS were contemporaneously transmitted via a helmet camera video feed to a video monitor in the dive shack. All audio communications were transmitted by radio link to the supervisor. The dive was recorded by the company’s DVR within the dive shack to confirm to the owner of the supertanker that the work done.
MS’s dive commenced at 09:34. On the radio running the dive was the diving contractor’s supervisor. A standby diver was designated, as were two tenders - one tending the diver’s umbilical, one tending the rotary scrubber’s hydraulic hose.
At the time of the project the DSV was positioned and moored the supertanker’s port side. MS had for 2 hours guided the rotary device along the port side hull and the flat bottom of the vessel. At approximately 120 minutes into his planned 200-minute dive a loud shrieking squeal is heard over the comms in the dive shack. This is a clear indicator of problems with air supply to a diver. Diver MS immediately pled “up and out on diver”. In reply to MS comment ‘up and out on diver’, the supervisor responded, “say again?” to which MS again reported “up and out on diver”. The supervisor confirmed his acknowledgement in replying “up and out on diver”; the supervisor then reported “coming up on you” apparently believing that MS was on the port side of the supertanker.
Within 22 seconds following the supervisor’s “coming upon on you” MS is seen surfacing on the video monitor on the starboard side of the vessel. MS was on the opposite side of the vessel from the dive vessel.
Immediately upon surfacing MS reports, “all right I’m having an issue with my air”. The DVD of the dive very clearly confirmed that on the monitor that the diver made three breaths and then mysteriously the audio feed disappears.
For a period of 90 seconds the video shows MS on the surface calmly treading water. Over that time period MS pivots 180 degrees and then begins slowly swimming toward the bow of the supertanker, he stops and reaches below the water to twice grab his umbilical. He lifts is head above surface and continues to tread water. It is then clear seen that MS then removes his dive helmet.
A close review of the video reveals that after removing his helmet MS remained next to the hull of the supertanker for an additional one minute. In response to what he sees the supervisor then panics and tells the tender to go “wake everyone up” as the diver removed his helmet. In response an awakened tender on surface panicked and pulls MS umbilical “keel-hauling” him to his death. A close viewing of the video shows MS convulsing on bottom. He remained on bottom for several minutes until the standby diver comes to his side and brings him to surface. Once on surface CPR is attempted to no avail.
HOW AND WHY DID THIS TRAGEDY OCCUR?
The designated tender, testified in sworn testimony that at the time of his diver reporting his problem, the tender was in the dive shack “with my eyes closed”, positioned away from his post on deck and yards from where he should have been tending MS’s umbilical. Upon his “seeing the diver taking his helmet off”, he testified that he was told by supervisor to “go wake up everyone” to assist help with the emergency.
One tender testified that he woke up the other tender who was behind the dive shack, apparently asleep; the secondary tender, upon hearing the excitement, ran and grabbed the umbilical and pulled it “double fast” until MS finally surfaced minutes later dead. This tender stunned, in a sleep induced stupor, was apparently unaware that prior to his “keel hauling” MS that the diver was on surface, helmetless and breathing the fresh salty air.
DELISE AND HALL’S REPRESENTATION OF THE DIVER’S FAMILY
Delise and Hall argued that MS died as follows. At 120 minutes into the planned 200-minute dive MS reported some type of problem with his helmet and/or air supply following a squealing sound from his helmet, which is clear indication of an air delivery problem. He surfaced and reported the problems clearly. Faced with the realization that staying in a helmet, which isn’t supplying him air he made the decision anyone would make under the circumstances. He removed his helmet to take in all of the fresh air that the world supplies.
The diving supervisor, inexperienced and exhausted, and who was quickly promoted two weeks earlier to fill the need of the husbandry SWAT team, panicked and ordered his tenders to “come up on the diver” believing he was on the port side of the supertanker. Delise and Hall argued that had the tenders been tendering his hose properly they would have known that MS was on the starboard side of the vessel.
Delise and Hall summarized its argument that the diving contractor was at fault because of its failure, through it’s on site supervisory personnel, to prepare a plan to complete the task at hand.
Delise and Hall also argued that the diving contractor failed to provide its crew proper rest and the training to complete the task at hand and were in direct violation of the ADCI minimum rest policies and procedures.
The diving contractor utilizes federally mandated safe practices manual. Included within the manual are requirements focusing on pre-project planning procedures, which include implementation of “safe actions plans” and formalized written Job Safety Analysis forms (JSA), specifically prepared for each project.
In this case the diving contractor grossly failed to prepare any such plans or JSA’s. In response to questions concerning what was told to the supervisor about the safe action plan the diving supervisor arrogantly replied under oath: “what is the plan? The plan is to go there, do the job and do it safely . . . the plan is to go there and clean the hull”. In response to a request for the JSA in place on the day of the incident the diving contractor’s representative could only produce a generic document having nothing to do with the work required.
Delise and Hall argued successfully that the diving contractor fell woefully short in planning for the manning requirements of the project. For the two days prior to MS’s death the diving contractor failed to adhere to the ADCI (Association of Diving Contractors International) minimum rest period requirements. On the day before MS’s death a Facebook entry by the diver’s tender posted that he was so tired on the job that he is “delusional”. Evidence will show that both tenders were either asleep or “with eyes closed” when the emergency occurred. Faced with MS’s emergency the exhausted crew responded in a confused disordered manner. They panicked clear and simple and the result proved fatal to MS.
Lastly, the diving contractor’s supervisors failed to put in place a plan to rescue a diver faced with MS’s peril.
In short, this was a project that was destined to kill a diver. The supervisor was inexperienced, the company was ill prepared to conduct such a project and its crew was overworked, under trained and incapable of dealing with an emergency.
Delise and Hall convinced the diving contractor’s insurance carrier to resolve the case during private mediation within one year of the death of MS. Because of the serious of the settlement terms the amount of resolution paid to MS’s family is confidential.
