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.

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”

INTERCARGO has published its Bulk Carrier Casualty report that analyses bulk carrier casualties over the period from 2008 to 2017. The report revealed that 53 bulk carriers over 10,000 dwt have been identified as total losses over that period with cargo shift and liquefaction remaining a great concern.

In 2017, the tragic losses of ‘Stellar Daisy’ carrying an iron ore cargo and ‘Emerald Star’ with a nickel ore cargo raised questions of structural integrity and safety condition of high density cargoes carried onboard. These two bulk carrier casualties caused the loss of 32 seafarers, the highest annual loss of lives since 2011.

As the report reveals, 9 casualties of suspected cargo failure consisted of 6 bulk carriers carrying nickel ore from Indonesia, 2 vessels with Continue reading “INTERCARGO Bulk Carrier Casualty report published”

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 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”

Former Cunard flagship Queen Elizabeth 2 opens as a hotel in Dubai

Posted on by News Hound

The legendary former Cunard flagship Queen Elizabeth 2 (QE2) is set to finally open its doors to the public as a hotel in Dubai tomorrow, April 18, almost 50 years after her completion by the John Brown shipyard in Scotland and more than nine years after her retirement from active Cunard service in November 2008.

Initial plans by Dubai World to convert the vessel to a hotel were disrupted by the 2008 financial crisis, but now PCFC Hotels – part of the Dubai government’s Ports, Customs and Free Zones Corporation – says it has “reinvented the legendary vessel as the latest must-see tourism destination, in a city renowned for its world-class attractions.”

The ship is now docked permanently at Mina Rashid, where her dining, accommodations and entertainment attractions will be unveiled.
