Dumping plastics into the sea is already prohibited under MARPOL regulations, which also oblige governments to ensure adequate port reception facilities to receive ship waste.

The IMO has pledged to address the significant problem posed by plastics to the marine environment, with the adoption of an action plan which aims to enhance existing regulations and introduce new supporting measures to reduce marine plastic litter from ships.

The plan was adopted on October 26 by IMO’s Marine Environment Protection Committee (MEPC).

Dumping plastics into the sea is already prohibited under MARPOL regulations, which also oblige governments to ensure adequate port reception facilities to receive ship waste. Under the London Convention and Protocol on the dumping of wastes at sea, only permitted materials can be dumped and this waste – such as from dredging – has to be fully assessed to ensure it does not contain harmful materials like plastics.

However, studies demonstrate that despite the existing regulatory framework to prevent marine plastic litter from ships, discharges into the sea continue to occur. Recognising that more Continue reading “IMO has adopted a plan to address the issue of marine plastic rubbish”

Preventing coal cargo from self-heating

Posted on by News Hound
The atmosphere in each cargo hold should be monitored, at least on a daily basis, for CO, hydrogen sulphide (H2 S), oxygen (O2) and flammable gas (LEL-methane).
The atmosphere in each cargo hold should be monitored, at least on a daily basis, for CO, hydrogen sulphide (H2 S), oxygen (O2) and flammable gas (LEL-methane).

London P&I Club has analysed the problems associated with the transportation of coal in bulk, such as self-heating and flammable gas (i.e. methane) release. Self-heating can lead to fires and the production of carbon monoxide (CO), whilst methane release can lead to an explosive atmosphere being generated in the hold.

Self-heating normally occurs in localised hot spots within a bulk cargo, and temperature measurements are unlikely to identify problems. However, when coal self-heats it produces CO, so measuring the concentration of CO is the most effective method to identify a self-heating cargo.

The atmosphere in each cargo hold should be monitored, at least on a daily basis, for CO, hydrogen sulphide (H2 S), oxygen (O2) and flammable gas (LEL-methane). If the holds are being ventilated, then ventilation should be stopped at least Continue reading “Preventing coal cargo from self-heating”

The FRPD 309 sustained damage to the shell plating and forepeak tank forward of the collision bulkhead. In addition, the port anchor was disconnected from its housing and became wedged in the Evco 60's hull
The FRPD 309 sustained damage to the shell plating and forepeak tank forward of the collision bulkhead. In addition, the port anchor was disconnected from its housing and became wedged in the Evco 60’s hull

The Transportation Safety Board of Canada released its investigation report into the collision of the dredger FRPD 309 with the loaded barge Evco 60, on 5 December 2017, in the Fraser River.

The incident
On 04 December 2017, the dredger FRPD 309 departed a shipyard in Delta, BC, to begin dredging in the Fraser River. The vessel is a conventional trailing arm suction dredger, with the bridge and accommodation located forward and machinery space located aft. Before departure, the crew had carried out pre-departure checks, a safety meeting, and emergency drills.

After arriving at the dredging location, the vessel started dredging sand and sediment from the river bed into the hopper using the 2 trailing arms and a dredging pump. When the hopper was filled, the sand and sediment was pumped ashore via a pipeline. The master left the bridge, handing over the command of the vessel to the officer of the watch (OOW). Two engineers, 2 deckhands, and a pipe operator were also on duty.

As the vessel was turning and the pipe operator was raising the trailing arms to the deck level, the vessel experienced Continue reading “Loss of propulsion leads dredger to collide with loaded barge says report”

From 1966 to 2015 there were 750 recorded fatal accidents involving passenger vessels, resulting in 59,600 fatalities.

The global passenger ferry industry has averaged more than 1,000 fatalities per year since the 1960s, with the great majority occurring on domestic voyages in Asia and Africa.

From 1966 to 2015 there were 750 recorded fatal accidents involving passenger vessels, resulting in 59,600 fatalities. Ninety-three per cent of ferry accidents occurred during domestic voyages, with 90% of fatalities occurring in just 20 countries and 76% in 10.

The Lloyd’s Register Foundation identified passenger ferry safety as a challenge in its Insight report on global safety challenges, in 2017. Since then The Foundation has investigated further to better understand the issue. It has drawn on expert knowledge and opinion to determine what activity is already underway to improve safety, what is further needed, and to Continue reading “Insight report on safety in the passenger ferry industry published”

TT Club issues advice on dealing with container fires

To tackle a fire in a hold, TT Club notes a CO2 system will be installed if the ship is carrying dangerous goods.
To tackle a fire in a hold, TT Club notes a CO2 system will be installed if the ship is carrying dangerous goods.

According to TT Club, container fires are a far more regular occurrence than most people would realise. Statistics show there is a major container cargo fire at sea roughly every 60 days. So, tackling fires and subsequent investigations are complex and vitally important activities.

With increasing container ships size increases the risk of a fire incident increases too. Despite some regulatory and technical advances, the fact is that the ability to respond to a cargo-related fire at sea has not progressed as needed in recent times.

To tackle a fire in a hold, TT Club notes a CO2 system will be installed if the ship is carrying dangerous goods. The gas released from a CO2 system can displace the oxygen in the hold and smother the fire. However, for CO2 to be effective, the hold must be closed to retain the gas and prevent oxygen ingress.

If an incident has taken place in a container stowed on deck, water will be the only option available . Nevertheless, it is unlikely to extinguish a fire inside a container in the short term.

In addition, crew members should seek Continue reading “TT Club issues advice on dealing with container fires”

The West of England P&I Club has warned operators and others involved of the dangers of carrying nickel ore. Carrying nickel ore can be dangerous, because of the risk of liquefaction of the cargo on passage when the moisture content is higher than the cargo’s Flow Moisture Point (FMP).

After a number of ships being lost, with liquefaction of their nickel ore cargoes suspected of being the cause, the West of England Club published a Notice some years ago addressing the Dangers of Carrying Nickel ore. This Notice is still in forced and was re-issued as No.13 2017/2018 – Dangers of Carrying Nickel Ore from Indonesia and the Philippines – Mandatory Notification Requirements (re-issued).

The Club reminds operators of the risk of liquefaction with this cargo, as showcased by the loss of the ‘Emerald Star’, which claimed the lives of 11 seafarers in October 2017.

In addition, the Club has been informed of Continue reading “The dangers of carrying nickel ore cargo and the associated risks are highlighted by The West of England P&I Club”

The Australian Maritime Safety Authority (AMSA) has experienced a steady increase in incident reports from 1,721 in 2013 to 3,017 reports in 2017. This is a 75% increase over a five-year period. For the period from 1 January to 30 June 2018, AMSA received 1,611 incident reports.

Key points to note

– During 2013-2017, the number of ship arrivals to Australian ports has increased by 21%.
From the 1611 incident reports in January-June 2018, the vast majority of occurrences (78%) concerned some form of technical issue.
– Among the technical issues, the most predominant occurrences relate to power, propulsion, and steering. This includes, for example, issues with a vessel’s main and auxiliary engines, and the steering gear and rudder.

AMSA uses incident data in combination with other sources of information, such as inspection and survey reports, research findings, accident investigations, and our day-to-day interaction with vessel crews, owners, and operators. This helps us gain a better understanding of Continue reading “AMSA stresses the importance of marine incident reports”

The US Coast Guard, in partnership with the American Waterways Operators (AWO), has published the National Quality Steering Committee’s annual safety report containing towing industry data for calendar years 1994 to 2017. The report reveals that in 2017, there were six operational towing vessel crew fatalities.

The National Quality Steering Committee looks at three safety measures to track overall trends in towing vessel safety and environmental protection: Crew fatalities per 100,000 towing industry workers, gallons of oil spilled from tank barges per million gallons transported, and the number of towing vessel casualties (overall and by incident severity).

The report also includes summary statistics on crewmember injuries, which the National Quality Steering Committee began tracking in 2006, for calendar years 2006 to 2017.

The decomposition progressed throughout the length of the vessel to such an extent that, after several days, the vessel’s Master took the decision to evacuate the crew.
The decomposition progressed throughout the length of the vessel to such an extent that, after several days, the vessel’s Master took the decision to evacuate the crew.

Following the investigation report of the 2012 built supramax bulk carrier M/V CHESHIRE which was issued by the Isle of Man Ship Registry, INTERCARGO urges IMO to reconsider how Ammonium Nitrate Based Fertilizer should be designated in the IMSBC Code. Currently, the Ammonium Nitrate Based Fertilizer is listed as a group C cargo, however, the accident showed that this cargo, or at least some of the ammonium nitrate based fertilizers shipped as this cargo, should treated differently under the IMSBC Code.

In August 2017, the 2012 built supramax bulk carrier M/V CHESHIRE, en route from Norway to Thailand, fully loaded with cargo declared by the shipper as being “Ammonium Nitrate Based Fertilizer (Non-hazardous)” and not liable to self-sustaining decomposition, suffered cargo decomposition that led to rising temperatures in the cargo holds and the generation of toxic gases.

The decomposition progressed throughout the length of the vessel to such an extent that Continue reading “Following the publication of the M/V Cheshire report, a recommendation is made that Ammonium Nitrate should not be treated as group C”

IACS updates guidance on bulk cargo loading and discharging

Posted on by News Hound
The process of planning and controlling cargo operations is addressed with special reference to the derivation of the loading and unloading plans and the requirements for ship/shore communication.
The process of planning and controlling cargo operations is addressed with special reference to the derivation of the loading and unloading plans and the requirements for ship/shore communication.

The shipping industry remains highly concerned about the possible damage and loss of bulk carriers carrying heavy cargoes. In July 2018, IACS revised ‘Recommendation 46’ referring to Bulk carriers loading and discharging to reduce the likelihood of over-stressing the hull structure in order to raise further awareness on the potential associated risks.

As explained, the loads that affect the ship’s structure are generally discussed with special reference to the structural strength limitations imposed by the ship’s Classification Society.

For instance, over-loading may induce greater stresses in the double bottom, transverse bulkheads, hatch coamings, hatch corners, main frames and associated brackets of individual cargo holds. In addition, overloading of the cargo hold in association with insufficient Continue reading “IACS updates guidance on bulk cargo loading and discharging”

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.

Probable cause
NTSB determines that the probable cause of the capsizing and sinking of the Gracie Claire was the Continue reading “Rudder compartment hull leak causes major capsizing of towing vessel says NTSB investigation”

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”
