Steel coils come in many sizes and weights, and can be arranged in various ways regarding the placement of the locking coil, the number of tiers, and the dunnage.
Often cargo planners who are preparing the stowage of steel coils in the cargo hold of a general dry cargo ship or bulk carrier, do not have the necessary cargo type specific information required to help them decide the permissible cargo load, thus preventing damage to the ship’s structure.
As Jan Rüde, Ship Type Expert MPV, DNV GL explains, according to SOLAS Chapter VI, Reg. 5, every ship must have an approved cargo securing manual.
Between September and November 2018, there were 8 reported fatalities related to enclosed spaces.
Although the industry continuously reminds the industry of the dangers of entering enclosed spaces, this remains the hidden enemy for crews. Between September and November 2018, there were 8 reported fatalities related to enclosed spaces. With this ongoing issue in mind the Shipowners Club has published a sample risk assessment addressing the various hazards associated with entering enclosed spaces.
In a span of just 18 months, the Club alone has experienced 15 related claims due to falls, asphyxiation, explosive burns and six fatalities. These alarming statistics have prompted the Club to produce a sample risk assessment on enclosed space entry as part of its ongoing campaign.
If the product meets the Class 4.3 criteria, it should be declared as UN 3170, noting the application of Special Provision 244 regarding ventilation and protection against water ingress throughout the intended journey.
The UK P&I Club and the TT Club have published advice following an incident involving a consignment of aluminium pellets (or dross) that was found at the port of loading with the doors and sides of the container blown out. The terminal arranged to test the samples, as there was no evidence that the unit had been dropped during handling.
The test results indicated that aluminium dross is highly susceptible to a reaction with chlorides when moisture is present. The commodity produces gases when exposed to moisture and the build-up of gasses was considered the most likely cause of the container exploding.
The container was damaged beyond repair and it is understood that some lines and ports are refusing this cargo commodity.
According to the UK Club, at the time the material is tested, before filling the container and subsequent shipping, the moisture level is such that the reaction with the commodity does not generate Continue reading “Beware the dangers of aluminium dross”
According to the guidelines, the transport of DVB without any temperature control generally relies on the DVB being at a low enough temperature when shipped.
The Cargo Incident Notification System (CINS), the International Group of P&I Clubs and the TT Club have published industry guidelines for the carriage of Divinylbenzene (DVB) in containers.
DVB is a chemical prone to polymerization (a form of self-reaction). When shipped in bulk, DVB polymerization can lead heat and flammable gas to be generated. Thus, the stowage of containers carrying DVB aboard vessels can present a risk of explosion and fire, if they are not properly presented for carriage.
As a series of polymerization incidents took place from the carriage of DVB by sea in 2018 the IMO approved changes to the way that polymerizing substances, like DVB, are carried, by amending the IMDG Code. These changes are included in amendment 39-18 of the IMDG Code, which will be mandatory from 1 January 2020, but may be applied voluntarily from 1 January 2019.
The accident was the result of procedural inadequacies and a lapse of supervision.
A crewman from the Liberian registered general cargo vessel, SMN Explorer, died when he was crushed by a falling hatch cover. The crewman was part of a working party stowing cargo slings used for the discharge of the ship’s cargo. The accident occurred when the crewman climbed up the inside of the open hatch cover after its locking pins had been removed.
The accident was the result of procedural inadequacies and a lapse of supervision. The investigation identified that the vessel’s safety management system was immature and the safety culture on board the vessel was weak. Risk assessments had not been conducted for routine tasks and a safe system of work had not been developed for opening and closing the forecastle (fo’c’s’le) stowage space hatch cover.
AMSA expects the vessel will be subject to a detailed examination by the operator and classification society.
The Australian Maritime Safety Authority (AMSA) has revoked the Australian Certificate for the Carriage of Livestock (ACCL) for the Panamanian flagged livestock carrier, MV Jawan, because the vessel’s approved stability data cannot be relied upon when the vessel is loaded.
The Jawan was (again) scheduled to depart from Portland on a journey from Australia to Pakistan on Monday after the vessel’s classification society Bureau Veritas, on behalf of the flag state, provided their assessment of the ship’s stability.
Hyperloop, Elon Musk’s high-speed-rail startup, has announced a new partnership with Hamburger Hafen und Logistik Aktiengesellschaft (HHLA) to explore ways to move shipping containers to and from inland sites with Hyperloop’s maglev-in-a-tube technology.
Initially, the joint venture plans to build a transfer station for testing purposes at an HHLA terminal in Hamburg and develop a Hyperloop transport capsule for standard shipping containers.
“With the Hyperloop transport system, HHLA is pursuing the goal of developing an additional component of efficient logistic mobility solutions in Germany,” said Angela Titzrath, chairwoman of HHLA’s executive board. “We want to employ innovative approaches to make a contribution towards relieving the strain on the transport infrastructure in and around the Port of Hamburg.” Continue reading “Hyperloop and HHLA are set to trial a new container by tube system”
Cargoes on the Trent, the Aire & Calder Navigation and the Sheffield & South Yorkshire Navigation included coal, stone, oil, gravel and sand. But one by one these traffics disappeared
Four years ago the Canal & River Trust launched a last-ditch attempt to revive commercial freight carrying on the larger waterways before it died out completely. How has it fared since then?
Back in the 1990s, any guide describing the canals and rivers of Yorkshire and the north eastern part of the network would make a point of emphasising how these large-scale waterways were still busy with freight barges loading several hundred tonnes each and helping to satisfy the nation’s transport needs – unlike the small-scale canals of the Midlands and most of the rest of the system, where regular commercial freight had died out a quarter of a century earlier.
Cargoes on the Trent, the Aire & Calder Navigation and the Sheffield & South Yorkshire Navigation included coal, stone, oil, gravel and sand. But one by one these traffics disappeared, not necessarily for Continue reading “What future for freight on the UK canal network?”
The classification of coal has been amended so that it will be treated as both Group A and B, unless otherwise tested.
On 1 January 2019 amendments to the IMSBC Code will apply. In an article to Gard Club, Penelope Cooke of Brookes Bell LLP, explains the impact of these changes on vessels carrying coal cargoes.
The amendments to the IMSBC Code regard the criteria under which coal cargoes are considered Group A, namely liable to liquefy, in addition to Group B chemical hazards which apply to all coal cargoes. Thus, coal cargoes may need the same TML and moisture certification as other Group A cargoes, such as concentrates, nickel ore and iron ore fines.
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”
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”
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’.
