A specialist system to rescue crew members who fall overboard has been developed by boat builder Goodchild Marine Services.

The Man Overboard Recovery Platform (MOB) has been designed to reduce the risk of cardiac arrest in anyone that has fallen overboard by lifting the casualty horizontally rather than vertically.

“This has become one of our bestselling products with widespread interest in the UK and abroad,” said Alan Goodchild, Goodchild Marine MD.

“Key features include an automatically-hinged propeller guard to prevent injury to the casualty, manual back-up and self-cleaning tracks.

The West of England P&I Club has said that it regularly receives claims arising from alleged shortages of solid bulk cargoes as a result of discrepancies between draught survey results. Draught surveys by their very nature are not an exact science and the accuracy of the calculated cargo figure may vary typically by between 0.5% and 1.0%. However, there are occasions when considerable differences in the cargo figures derived from the draught surveys have been obtained.

The commonly forgotten weights are:

– Bilge water present in the cargo holds, machinery spaces, duct keel, void spaces and the chain lockers.

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

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, no bilge alarms sounded. 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.

Intelligent wireless bolts in wind turbines or satellites may be able to let the operator know when something is wrong

In the future, intelligent wireless bolts in wind turbines or satellites may be able to let the operator know when something is wrong. This could reduce the risk of human injuries and save cost.

A research team at NTNU in Gjøvik is working to create bolts that send an alert when something is not as it should be or when maintenance is needed. Each bolt must be able to contact a control center, which will receive messages from all intelligent bolts of this type in all installations around the world.

The team working on these wireless bolts includes Professor Michael Cheffena, two fellows and the manufacturer Dokka Fasteners. The vision of the research team is to develop wireless sensors to be installed inside the bolts. If the sensors detect that something is Continue reading “Are ‘Smart Bolts’ the thing of the future?”
