Several problems can arise when transporting steel cargoes by sea reports North P&I. The more common issues can be broadly categorised as mechanical damage, or rust-related problems. Indeed, in many cases the damage occurs before it is even loaded onto the carrying vessel. North of England P&I Club has elected to publish a briefing document providing best advice leading to the minimisation of the risk of cargo damage.

Common issues that can result in damage to the cargo include poor handling, substandard stowage and securing, water ingress into the hold and improper hold ventilation.

Key issues
Pre-shipment condition: It is not uncommon for steel cargoes to Continue reading “The appointment of a suitably experienced surveyor is vital to avoid steel cargo damage says North P&I”

The Methanol Institute has welcomed the findings of the Sustainable Marine Methanol (SUMMETH) project, which has backed the increased use of Methanol as a marine fuel.

The research concluded that there are no obstacles to the efficient use of Methanol in a converted diesel engine and that smaller vessel conversion projects are feasible and cost-effective, with levels of safety that easily meet existing requirements.

Switching to Methanol would offer immediate environmental benefits, including close to zero SOx and particulate matter emissions and significantly lower NOx emissions compared to conventional marine fuels or biodiesel.

The fire could not be contained, so the master ordered the ship to be abandoned.
The fire could not be contained, so the master ordered the ship to be abandoned.

A poor safety culture and the ineffective implementation of a safety management system were identified as the most likely causes of the 2016 fire aboard the RoRo vessel Caribbean Fantasy.

The vessel’s main engine room was hit by fire in the morning hours of 17 August 2016, when fuel spraying from a leaking flange came in contact with a hot surface on the port main propulsion engine, the National Transportation Safety Board (NTSB) said in a report.

The fire could not be contained, so the master ordered the ship to be abandoned. At the time of the incident, the Baja Ferries-operated vessel was 2 miles northwest of San Juan, Puerto Rico.

German authority report suggests containers on two ships caught fire probably from self-heating

Posted on by News Hound

The German Federal Bureau of Maritime Casualty Investigation has released its reports about two non-connected fires on container ships. The MSC Katrina was in the Elbe estuary when the fire was detected on 20 November 2015. The second ship, the Ludwigshafen Express was in the Red Sea when fire was noticed during an inspection in February 2016.

The first incident
The MSC Katrina was located in the Elbe estuary when its smoke detection system discovered fire. As a result, the Central Command for Maritime Emergencies had the ability to deploy specially trained firefighters.

There have been a number of shore side marine bollard failures whereby moored vessels were cast adrift

The USCG issued an alert informing that recently, there have been a number of shore side marine bollard failures whereby moored vessels were cast adrift. In some cases, this resulted in damage to the involved vessel, as well as other nearby vessels and shore side structures, the USCG warned.

Neither the USCG nor the Occupational Safety and Health Administration (OSHA) has regulatory oversight over these items. In several cases, the underlying deficient material condition of the bollards was unknown until the failures occurred.

Key causes include:
– the rotting of organic bollards made of marine pilings,
– the undetected fracture of bollard castings due to manufacturer defects,
damage from previous overloads, or
– the degradation of bollard foundations and fasteners.

Typically, the failures are associated with abnormal dynamic loads transferred to the bollard from a vessel. The abnormal loads are oftentimes caused by Continue reading “Recent marine bollard failures give USCG cause for concern”

Ethylene vapors activate carbon monoxide alarm says safety alert

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”
