The London P&I Club together with Paul Willis Senior Associate at Hawkins have published a loss prevention guide regarding the risks of carrying coal cargoes. The report gives special consideration to the issues surrounding gas monitoring and ventilation.

The guide mentions that the management of coal cargoes and the proper use of gas detection equipment are vital to prevent coal fire claims. It also details the basic requirements regarding the installation, use and maintenance of gas detection devices and the different types of sensors involved in their operation.

According to the report, the gas detection and monitoring equipment on board ships can vary from large units such as the Riken Keiki RX–515 to smaller more portable types such as the BW Gas Alert Max XT II.

The International Council on Combustion Engines (CIMAC) has released a statement on marine fuel incidents that have occurred this year highlighting that it is unable to draw any firm conclusions about the cause of the problems.

CIMAC Working Group Fuels – WG7 – made the statement after the unusually large number of ships that experienced marine fuel incidents with seemingly on-spec fuels earlier this year. The statement confirms much of what the International Bunker Industry Association (IBIA) has already said on the issue.

In March 2018, a number of ships experienced operational problems using residual fuels bunkered in Houston. The analyzed fuels met the Continue reading “CIMAC unable to explain marine fuel incidents that occurred earlier this year”

Cargo hold cleaning is a critical aspect of the complex bulk carrier operations that require careful preparation to maintain cargo quality and to avoid any delays. A conventional bulk carrier may transport coal this week and soya beans the next week, which requires thorough wash-downs and cleaning in between. Danish shipping company Norden has said it has tested a cargo hold robot which can be remotely operated to prevent risk and delays, also leading to enhanced safety for crew and others who are required to enter holds.

The prototype, developed by Danish company CLIIN with assistance from the Market Development Fund, is a new belt-driven robot which can be operated remotely to go up and down along the sides of the holds while pressure cleaning them. The robot is driven forward by Continue reading “Cargo hold cleaning robots undergo testing”

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”

How to conduct a safe bunkering operation

A number of safe bunkering measures are required for each bunkering operation. These can be divided into four stages and checks
A number of safe bunkering measures are required for each bunkering operation. These can be divided into four stages and checks

The UK P&I Club has published helpful guidance to ensure safe bunkering operations. The Club said that bunkering operations are routine and critical, high risk operations which require to be carefully planned and performed.

Causes of bunker spills

Although the most of the bunker transfers are carried out without incident, very occasionally, things can and do go wrong. The UK Club notes that only a minority of cases do bunker spills occur because of failure of the hoses or pipelines, while the majority of spills result from a tank overflowing.

But these are not the only causes. Common causes of bunker spills can be summarised as follows:

– Improper set up of pipeline system valves: Potentially causing either overpressure, or flow of bunkers to an unintended location;
– Insufficient monitoring of tank levels during bunkering: All tanks, not only those Continue reading “How to conduct a safe bunkering operation”

Maersk sets new guidelines on dangerous cargo stowage following Honam tragedy

Posted on by News Hound
The Risk Based Dangerous Goods Stowage principles have been developed to minimise risk to crew, cargo, environment and vessel in case a fire develops. The different container vessel designs were reviewed from a risk mitigation perspective and ultimately six different risk zones defined.
The Risk Based Dangerous Goods Stowage principles have been developed to minimise risk to crew, cargo, environment and vessel in case a fire develops. The different container vessel designs were reviewed from a risk mitigation perspective and ultimately six different risk zones defined.

In the aftermath of the major fire that killed five crew members onboard the ‘Maersk Honam’ in March 2018, Danish container ship giant Maersk has conducted a thorough review of their current safety practices and policies with reference to the stowage of dangerous cargo. Consequently, Maersk has now announced the implementation of new guidelines to improve safety across its container vessel fleet.

On 6 March 2018, the container ship ‘Maersk Honam’ suffered a serious fire in its cargo hold where dangerous goods were carried, but up to this time, there is no evidence to suggest that dangerous goods caused the fire, the company noted. In addition, all cargo was accepted as per the requirements of the IMDG Code and stowed onboard the vessel accordingly.

Following the tragic incident, Maersk took measures and implemented additional preliminary guidelines for stowage of dangerous goods. The company evaluated over 3,000 UN numbers of hazardous materials in order to further understand and improve dangerous cargo stowage onboard container vessels and developed a new set of principles called ‘Risk Based Dangerous Goods Stowage’.

Together with ABS, Maersk called for a workshop with other industry stakeholders to conduct a Continue reading “Maersk sets new guidelines on dangerous cargo stowage following Honam tragedy”

Transport Malta’s MSIU issued an investigation report on the fatality of a crew member onboard the Maltese-registered chemical tanker ‘Scot Berlin’ in August 2017. The immediate cause of the accident was the entry into a space which had a significant presence of toxic gases suspended in the air.

The Scot Berlin arrived at Marsaxlokk Oil Tanking Terminal loaded with two parcels of cargo. Following the completion of cargo operation, the crew members started the ballasting of the vessel since her next trip to Spain was a ballast voyage. Ballasting in the forepeak tank started under the supervision of the second mate.

Red Ensign Group members have been attending an intensive course aimed at working with them to ensure their safety during marine casualty investigation and incidents are carried out in line with international requirements.

While the REG delegates are already experienced in such investigations, the course run by the UK-based Marine Accident Investigation Branch combines the requirements of the International Maritime Organization’s Casualty Investigation Code with its own experience and best practice.

David Wheal, principal inspector of marine accidents at the MAIB is one of the team that created the course. He said: ‘This is not designed to replace the formal training we would expect investigators to have. This course serves as a platform for future refresher and enhanced training.’ Continue reading “Marine casualty investigation training provided to Red Ensign members”

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”

Fears over engine failures as industry switches to low sulphur fuel

By Ellen Milligan (Bloomberg). Add oil tankers breaking down at sea to the list of things shipping companies are worrying about as they brace for a once-in-a-generation overhaul to the kind of fuel the industry must consume as the industry switches to low sulphur fuel.

From Jan. 1, 2020, the vast majority of the world’s merchant fleet will have to use low sulphur fuel containing no more than 0.5 percent sulfur, down from 3.5 percent in most parts of the world today. The change is expected to upend both shipping and refining industries, with analysts forecasting higher oil prices, slower-sailing ships, and some observers even warning of risks to world trade.

Now more and more of the world’s largest shipping companies and trade groups, already mindful of spiralling costs, are saying there’s a safety risk too. Their primary worry is the lack of a single fuel type that complies with the rules. Since refineries across the world are coming up with different solutions to meet the sulfur-reduction target, owners say their ships’ engines could be damaged by inadvertently mixing incompatible products.
