The USCG has published a safety alert informing marine inspectors that ethylene vapors on LNG carriers can activate Carbon Monoxide alarms. Specifically, during an examination of a LNG carrier whose cargo tanks contained ethylene vapors, PSC Officers (PSCOs) received alarms on their portable four gas meters giving a reading of 60 to 100 parts per-million (PPM) Carbon Monoxide (CO).

A certified marine chemist traced the source of the vapors to an eight inch crack on a cargo vapor line. PSCOs initially thought the alarm was related to a combustion event and did not suspect the ethylene vapors were the source, because they did not get a Lower Explosive Limit (LEL) reading on their monitors.

The chemist indicated that the LEL most likely never alarmed because of high winds on deck. He further explained that the molecular weight of Ethylene (28 g/mol) was identical to the molecular weight of CO which accounted for the CO PPM readings. USCG personnel contacted the manufacturer who confirmed that Continue reading “Ethylene vapors activate carbon monoxide alarm says safety alert”

Incorrect oxygen welding gas hose led to fire

Posted on by News Hound
The hose had been recently replaced, but the replacement hose was a hydraulic oil service hose with oxygen fittings.
The hose had been recently replaced, but the replacement hose was a hydraulic oil service hose with oxygen fittings.

In its latest Safety Flashes, IMCA presents a case of a fire due to incorrectly selected oxygen welding gas hose, during a routine cutting job onboard a ship. There were no injuries or ship damage, but investigation later revealed that the hose had been recently replaced with one that did not comply with ISO 14113 specification.

The incident

The ship’s welder opened the Oxygen and Acetylene gas bottle valves in order to do a cutting job on deck. These gas bottles were attached to the vessel’s integrated welding gas system. Opening the valve on the Oxygen bottle caused an explosion to a short, high pressure hose delivering oxygen from the bottle to the oxygen gas regulator. The end of the hose caught fire and was quickly extinguished by turning off the oxygen bottle. Nobody was injured and the only damage was to the hose that completely separated.

Findings

The hose had been recently replaced, but the replacement hose was a hydraulic oil service hose with oxygen fittings. The replacement hose was not Continue reading “Incorrect oxygen welding gas hose led to fire”

Sinking raises safety issues on bilge alarms

The failure of engine cooling system pipework is one of the most common causes of flooding on small fishing vessels
The failure of engine cooling system pipework is one of the most common causes of flooding on small fishing vessels

In its latest Safety Digest, the UK MAIB provides learnings about an 8.13m fibreglass fishing vessel that was engaged in picking up its fleets of creels when it began to take on water and subsequently sank. The skipper, who was working alone, managed to deploy the boat’s liferaft and climb into it as the boat was sinking and was later rescued without injuries.

The incident

The skipper went out to sea shortly after daybreak to recover his two fleets of creels. The weather was good. As soon as he arrived at the fishing grounds, he hauled in the first fleet of creels and stowed it on the aft end of the deck. He then headed at speed toward the second fleet of creels.

The Swedish Club has published a report warning bulk carrier owners to pay extra attention to the basics. The Club has concluded that for bulk carrier operators, wet damage is the most costly claim type and the second most common claim that they experience.

The report is entitled Wet Damage on Bulk Carriers and has been prepared in cooperation with DNV GL, and MacGregor. It identifies heavy weather and leaking hatch covers as the most common and the most costly type of wet damage claim and the average cost for a wet damage cargo claim being almost $110,000.

Whilst weather routeing minimises the effects of Continue reading “Wet damage the most costly claim for bulk carriers says The Swedish Club”

London P&I Club reveals key causes of recent container loss claims

A recent run of container loss claims by the London P&I Club has highlighted some of the common contributory factors that emerge as part of the investigation process. The Club noted that the subject of misdeclared container weights continues to be a problem. But with this particular run of claims it was the attending surveyor’s observations about cargo securing equipment that caught the eye.

In these cases, it became clear that several manual twist locks were not correctly locked at the time of the incident. The causes for this were considered to be two-fold – some twist locks were damaged (specifically with locking levers either bent or missing), or the units in service were a mixture of right and left-hand locking units, leading to confusion over the observed status of the twist lock.

Upon investigation, a number of container corner castings and container foundations showed no signs of having a locked twist lock forcibly removed during the collapse, the natural conclusion being Continue reading “London P&I Club reveals key causes of recent container loss claims”

Martek Marine provides superyacht D-Fence from drone threat

The superyacht fraternity are waking up to the growing threat that drones pose to privacy, safety & security on-board their yachts. Recent years have seen a massive advance in drone endurance, range and payload capacity whilst the price has also plummeted, leading to a proliferation of drones expected to reach 12 million by 2020.

Terrorist use of drones deploying explosives and poison gas attacks are well documented. The potential for a drone to deliver an explosive charge or even payloads such as nerve-gas on-board a superyacht is a stark reality. Paparazzi intrusion using drones approaching superyachts is already a recognised and growing problem. Yachts in port, at anchor or on coastal transits are simply ‘sitting ducks’ and currently powerless to know if/when they’re going to be attacked, let alone be in a position to defend against the threat.

To combat this emerging threat Martek Marine have Continue reading “Martek Marine provides superyacht D-Fence from drone threat”

Standard P&I Club issues a guide to fire safety on ferries

A fire is one of the most frightening things that can happen at sea. Often, seafarers have no ready access to the
emergency services when a fire breaks out and will need to rely on their own resources, courage and training to tackle and extinguish the blaze quickly to ensure the safety of the ship and everyone on board. To help Standard P&I Club has issued a guide to fire safety on ferries.

There are numerous causes of fire but the most relevant to ferries are:

– Electrical defects, such as overloaded electrical equipment, damaged cables and poorly formed connections. – Electrical faults in vehicles, especially when engines are hot/running. Reefer containers are major sources of fire.
– Mechanical failure, such as ignition from overheated bearings or a catastrophic engine failure.
– Uncontrolled release of oil or flammable liquid coming into contact with a hot surface, or the release of a low flashpoint fuel, such as petrol vapour, coming into contact with a source of ignition.
– Dry, readily combustible materials (such as wood, paper, textiles) coming into contact with an ignition source, such as a lighted cigarette, sparks or conducted heat from burning or cutting, highintensity lights or defective electrical equipment.

DMS Holland to start developing stabilisers for fast-planing yachts

Following the successful development and subsequent launch to market of the electric roll damping system for yachts up to 30 metres, the MagnusMaster, DMS Holland has now started, in cooperation with Brabant Engineering, the development of a roll damping system for fast-planing yachts up to 30 metres.

This new AntiRoll damping system, like the MagnusMaster, will be produced as a standard-series stabiliser. Until now, AntiRoll has only been developed as a ‘custom build’ for super- and mega yachts. DMS Holland will be taking this patented dual-axis fin stabiliser and using it to form the basis for their new system. The fundamental concept behind AntiRoll remains the same, namely high-aspect fins that rotate whilst sailing and flap whilst the yacht is at anchor. It is stabilisation at fast speed that will form the extra addition and make it a 3-in-1 stabiliser. “How this will actually be achieved we are keeping to ourselves for a little while longer yet,” says Patrick Noor, DMS Holland’s co-owner responsible for sales & marketing.

Arnold van Aken, inventor of the dual-axis fin stabilisation AntiRoll system and co-owner / Technical Director of DMS Holland explains: “For years we have been Continue reading “DMS Holland to start developing stabilisers for fast-planing yachts”

Improper securing arrangement of sea strainer cover leads to vessel capsizing

Shipowners P&I Club has issued a case study about the capsizing of a vessel due to a loose port side sea strainer. Whilst double banked alongside another tug for four months awaiting a placement in dry dock, a harbour tug suddenly developed a list to port. Crew on board at the time quickly investigated to try and determine the point of water ingress, but struggled as the water level reached approximately 1 metre in height in the flooded engine room.

As the engine room crew tried to establish and stop the source of ingress, the deck crew were adjusting the mooring ropes to keep the vessel safely alongside as the vessel listed further to port. Eventually, the master took the decision to abandon the vessel as it was no longer safe to remain on board.

Norway targets IMO to halve global shipping emissions by 2050

Global shipping should set a goal of halving greenhouse gas emissions by 2050, Norway’s government and shipowners’ association said on Thursday before talks by the International Maritime Organization (IMO) in London next week.

Norway’s fleet is worth about $45 billion, the fifth most valuable in the world behind Japan, Greece, China and the United States. Norway’s shipping includes offshore, gas, chemicals, car vessels, dry bulk, crude, crude products and containers.

The IMO, which says international shipping represents about 2.2 percent of world carbon dioxide emissions, will meet from April 9-13 to develop a strategy to combat climate change. Shipping was not included in the 2015 Paris climate agreement.
