Incorrect oxygen welding gas hose led to fire

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.

Are ‘Smart Bolts’ the thing of the future?

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

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”

The UK Maritime & Coastguard Agency (MCA) and the Royal National Lifeboat Institution (RNLI) have run a special week-long event to test the use of drones along a stretch of coastline at St Athan, Wales. The testing took place between 23 and 27 April. A selection of drones were used in four different search and rescue scenarios to explore how they could be used to help save lives in the future.

The scenarios were a shoreline search for a casualty, an offshore search for multiple casualties in the sea, a mud rescue and a communications blackspot where a drone is required to relay information between rescue teams and a casualty on a cliff.

Featuring RNLI lifeboats and an HM coastguard search and rescue helicopter, the scenarios explored Continue reading “UK MCA and RNLI test drones for search and rescue”

Denmark cancels registration fee for Danish Register in attempt to boost fleet size

The aim of this amendment is to increase the attractiveness of the Danish Flag

The Danish Parliament adopted a legislative amendment on 26 of April, which cancels the registration fee for vessels in the Danish Registers of Shipping. The aim of this amendment is to increase the attractiveness of the Danish Flag.

Denmark supports that this measure will indeed increase the attractiveness of the Danish Flag, as it now offers the same benefits as foreign Flags.

This amendment also provides increased economic activity and international influence, when the Danish Flag attracts more vessels from both national as foreign shipowners.

The amendment will enter into force on the Continue reading “Denmark cancels registration fee for Danish Register in attempt to boost fleet size”

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”

Heinen & Hopman have launched new CFD-analysis service to reduce HVAC costs

Marine HVAC supplier Heinen & Hopman has introduced a new service that can accurately predict where deficiencies in an HVAC system may occur before mounting a single piece of equipment on board a vessel.

According to Heinen & Hopman, computational-fluid dynamics (CFD) technology is used to analyse the HVAC-system design to validate whether the HVAC installation shall meet specific requirements.

In a recent press release, Heinen & Hopman outlined, “CFD is a well-established technology in many industries. With CFD technology, airflows can be realistically simulated to identify common HVAC problems, such as drafts, high levels of turbulence, high-pressure drop[s] and poor air-distribution. CFD considers everything from Continue reading “Heinen & Hopman launches new CFD-analysis service to reduce HVAC costs”
