Rudder compartment hull leak causes major capsizing of towing vessel says NTSB investigation

Posted on by News Hound
NTSB determines that the probable cause of the capsizing and sinking of the Gracie Claire was the towing vessel’s decreased stability and freeboard due to undetected flooding through a hull leak in the rudder compartment, which made the vessel susceptible to the adverse effects of boarding water from the wake of a passing vessel.
NTSB determines that the probable cause of the capsizing and sinking of the Gracie Claire was the towing vessel’s decreased stability and freeboard due to undetected flooding through a hull leak in the rudder compartment, which made the vessel susceptible to the adverse effects of boarding water from the wake of a passing vessel.

The US NTSB issued an investigation report on the capsizing of the towing vessel ‘Gracie Claire’, while moored on the Lower Mississippi River in Venice, Louisiana. The report revealed that several factors affecting the stability of the vessel led to its capsizing.

The incident
On 23 August 2017, at 0756, Gracie Claire was moored in Tiger Pass near mile marker 10 on the Lower Mississippi River. While taking on fuel and water, the towboat began to slowly list to starboard. After the wake of a passing crewboat washed onto the Gracie Claire’s stern, the list increased. In a short period of time, water entered an open door to the engine room and flooded the space.

The towboat sank partially, its bow being held above the water by the lines connected to the dock. All three crewmembers escaped to the dock without injury. Approximately 1,100 gallons of diesel fuel were discharged into the waterway. Damage to the Gracie Claire was estimated at $565,000.

Once this is ensured, the owner, manager and shipmaster of the affected Singapore-registered ships should alert MPA of the incident immediately or at the latest, within 2 hours.
Once this is ensured, the owner, manager and shipmaster of the affected Singapore-registered ships should alert MPA of the incident immediately or at the latest, within 2 hours.

MPA Singapore issued a marine notice to inform operators of Singapore-registered ships on the procedure of reporting of any marine casualty, incident or security-related incident involving Singapore-registered ships.

To begin with, the following can be considered to-be-reported marine incidents:
– the death of, or serious injury to, a person;
– the loss of a person from a ship;
– the loss, presumed loss or abandonment of a ship;
– material damage to a ship;
– the stranding or disabling of a ship, or the involvement of a ship in a collision;
– material damage to marine infrastructure external to a ship, that could seriously endanger the safety of the ship, another ship or an individual; or
– severe damage to the environment, or the potential for severe damage to the environment, brought about by the damage of a ship or ships.

As noted, the general principle in any incident is that urgent steps on the ground, in accordance with ships’ and companies’ approved plans, must first be taken by Continue reading “MPA Singapore has issued advice on how to conduct effective marine incident reporting”

An explanation to cargo ships that sink when their cargo liquefies

Posted on by News Hound
Solid bulk cargoes are typically “two-phase” materials as they contain water between the solid particles.
Solid bulk cargo are typically “two-phase” materials as they contain water between the solid particles.

Think of a dangerous cargo and toxic waste or explosives might come to mind. But granular cargoes such as crushed ore and mineral sands are responsible for the loss of numerous ships every year. On average, ten “solid bulk cargo” carriers have been lost at sea each year for the last decade.

Solid bulk cargoes – defined as granular materials loaded directly into a ship’s hold – can suddenly turn from a solid state into a liquid state, a process known as liquefaction. And this can be disastrous for any ship carrying them – and their crew.

In 2015, the 56,000-tonne bulk carrier Bulk Jupiter rapidly sunk around 300km south-west of Vietnam, with only one of its 19 crew surviving. This prompted warnings from the International Maritime Organisation about the possible liquefaction of the relatively new solid bulk cargo bauxite (an aluminium ore).

A lot is known about the physics of Continue reading “An explanation to cargo ships that sink when their cargo liquefies”

Frequency of total hull losses at its lowest since 1996 reports Cefor

Cefor Hull Trends 2018
Cefor Hull Trends 2018

The number and impact of major and total hull losses has remained low since 2016, a trend that has continued into the first half of 2018, according to figures by the Nordic Association of Marine Insurers (Cefor).

The overall claims frequency continues its positive trend and stabilizes at a relatively low level, and total loss frequency reached a minimum again in the first half of 2018, and continues thus the last year’s trend with some oscillation at low levels.

Insured values dropped on average 2.5% on 2018 renewals. The improvement compared to the previous years is especially due to some recovery in the supply/offshore segment in 2018, following a recovery in the bulk market in 2017. However, it should be noted that Continue reading “Frequency of total hull losses at its lowest since 1996 reports Cefor”

Accidents in enclosed spaces onboard ships have been a source of serious injuries and fatalities for many years, yet still they happen. Analysis of the accidents shows failure to follow established procedures many times leads to such accidents and incidents. In this video published by Gard P&I Club, you will see Gard’s former surveyor, Alf Martin Sandberg’s story, who could have lost his life when he entered Click to w void space onboard a barge without checking the atmosphere inside the space first.

This story is a real-life reminder that accidents can happen in any enclosed spaces. For this reason, every precaution should be taken both before to entry and while inside an enclosed space, and that even trained professionals make mistakes.

Watch the eight-minute video. Continue reading “Gard releases video about avoiding enclosed spaces accidents”

The examination showed that the damaged nitrogen cylinder had suffered significant corrosion at the point of failure.

The Bahamas Maritime Authority issued a safety alert regarding the potential serious risk for safety on board a ship where nitrogen cylinder are used as a stored kinetic energy system for launching lifeboats. This alert was issued after the authority obtained information from an ongoing maritime incident investigation conducted by the Transport Accident Investigation Commission, New Zealand.

The vessel had hydraulically powered davits with six power packs, three on each side of the vessel. A stored energy system consisted of a piston accumulator and a bank of four high pressure (180-210 Bar) nitrogen cylinders were fitted to each lifeboat launching davit.

In February 2017, one of the nitrogen cylinders of a stored energy system onboard exploded while being topped up to maintain the correct pressure. A crew member died as a result of the explosion. The findings of the investigation indicate that significant corrosion affected the structural integrity of the cylinder.

The remains of the exploded nitrogen cylinder and other three cylinders from the same Continue reading “BMA releases safety bulletin following nitrogen cylinder fatality”

A sea anchor is a vital component to a rescue boat, reducing the likelihood of it drifting away or spinning around, and keeps it steady in the wind.
A sea anchor is a vital component to a rescue boat, reducing the likelihood of it drifting away or spinning around, and keeps it steady in the wind.

As more people are heading out to sea over summer, safety both onboard and overboard is under the spotlight. For this reason, an ISO has been updated for the effectiveness of sea anchors for rescue boats known as ‘ISO 17339:2018, Ships and marine technology – Life saving and fire protection – Sea anchors for survival craft and rescue boats.’

A sea anchor is a vital component to a rescue boat, reducing the likelihood of it drifting away or spinning around, and keeps it steady in the wind. The updated ISO for the performance and safety of sea anchors brings them in line with the IMO’s International Life-Saving Appliance Code.

The International Life-Saving Appliance Code prescribes the carriage and use of sea anchors for survival craft and rescue boats, yet the revised recommendation on testing of lifesaving appliances does not provide requirements of performance and testing procedure for the sea anchors. This document addresses those areas, which the IMO recommendation does not address, in order to enable consistent implementation by maritime Administrations.

The new ISO addresses the performance and testing of Continue reading “ISO updates guidelines for sea anchors on survival craft and rescue boats”

The COI reports operational limitations which may have been exceeded while the voyage took place.

The US Coast Guard released the Certificate of Inspection (COI) for the ‘Stretch Duck 07’, the amphibious tour boat that sunk in Table Rock Lake, Missouri on July 2018 with the loss of 17 lives.

The COI reports operational limitations which may have been exceeded while the voyage took place. The limitation included limits on permissible weather and surface conditions.

It also indicates that the boat’s stability letter was issued on March 2009, and its last “drydock” was carried out in January 2017. Its operations were to occur in Table Rock Lake and nearby Lake Taneycomo, and it was not permitted to operate on the water “when winds exceed thirty-five (35) miles per hour, and/or the wave height exceeds two (2) feet”.

In addition, the US Coast Guard established a Marine Board of Investigation (MBI) after the sinking of the Stretch Duck 07 boat in Branson, Missouri on July 19. An MBI is US Continue reading “USCG issues fated duck boat’s COI in an unusual move”

From January 2021, AMSA is imposing regulation that float-free EPIRBs will be mandatory on certain types of commercial vessel. This change to safety requirements is in response to tragic incidents in which commercial vessels sank quickly and the master and crew were not able to deploy their EPIRB in time.

A float-free auto-activating EPIRB can send a call for help within minutes of being submerged in water without any action by the crew. As AMSA General Manager of Standards Brad Groves said, float-free EPIRBs offer significant safety advantages for crew and passengers on vessels in distress.
