Pods versus water lubricated props – greater comparative studies required says Thordon Bearings

Posted on by News Hound

Giant Ship PropellorsThordon Bearings has called on the marine industry to investigate the characteristics of both conventional seawater-lubricated propeller shaft systems and podded propulsion arrangements in order to provide shipowners with a better understanding of the two very different propulsion configurations.

In a recently published White Paper, the Canadian manufacturer of the COMPAC seawater-lubricated propeller shaft bearing system believes there is a great opportunity for independent comparative data so that cruiseship operators, in particular, can make more informed procurement decisions.

Highlighting the development of both systems, the 24 page paper asks if the water-lubricated propeller shaft is more efficient than podded propulsion, encouraging readers to assess a number of different factors before selecting their optimum propulsion solution.

Liverpool set to become the Silicon Valley of the maritime world?

Posted on by News Hound

DockyardArticle reprinted from the Liverpool Echo and written by Liam Murphy

Hi-tech barges could be built at Merseyside’s Cammell Laird as part of plans to make the region “the Silicon Valley for the maritime sector”. The aim is to replace the thousands of lorry journeys expected to be generated when the massive new Liverpool2 port is fully opened with tidal and solar powered vessels. Plans are now being drawn up for the barges – which could even be automated – to transport freight containers from the new deepwater port further inland down the Manchester Ship Canal to Salford docks.

Isle of Man Ship Registry issues new guidance on refrigeration gas storage

Posted on by News Hound

Isle of Man Ship Registry has issued a Manx Shipping Notice (MSN) to provide guidance to all Isle of Man Registered vessels on the installation and maintenance of oxy-acetylene and refrigeration gas equipment. This MSN replaces Industry Circulars 14 and 20 which are withdrawn.

Gas cylinders containing refrigeration gas and nitrogen are normally sent to the ship full and returned to a service provider when empty. These gases are not corrosive and providing the bottle contains the original gas sent from the supplier (and gas has not been added to the bottle on board) the bottles can be periodically inspected and tested at intervals in accordance with the RID/ADR regulations. In most cases, for refrigeration gases and nitrogen this is at 10 yearly intervals.

New design of coastal feeder ship wins Japan award

Posted on by News Hound

Feeder ship with innovative new designA coastal feeder vessel featuring a novel, aerodynamic bow form has been voted ‘Best Small Cargo Ship’ at the Japanese Ship of the Year event hosted by the Japan Society of Naval Architects and Ocean Engineers (JASNAOE).

Deployed since delivery in December on the Japanese feeder network operated by Imoto Lines, the 548 teu Natori won the award on account of its energy-saving and safety features. The vessel is highly unusual in appearance, by virtue of a hemispherical-like prow, with integral, rounded forward bridge and superstructure, rendering a highly unusual appearance.

AMSA notifies changes in its certification and accreditation services from 2017

Posted on by News Hound

AMSA has issued new edition of its publication ‘ Working Boats’ including information regarding changes in its certification and accreditation services.

Currently, even though AMSA is responsible for regulating domestic commercial vessels (DCVs) across Australia, the way you get your services — such as certificates and vessel IDs, undertaking surveys and the fees associated with these services — is not the same around the country. Those services are currently delivered by each state and territory, which sets its own procedures and fees for these services.

Surveyors beware of how to avoid claims for ‘cooking’ soya beans

Posted on by News Hound

Soya beansThe latest issue of North P&I Club’s loss prevention newsletter has advised operators to be extra vigilant during loading and transport of soya beans to ensure they do not get blamed for cargoes that start “cooking” at sea.

North’s loss prevention director Tony Baker says, “We have experienced a number of high value claims in China associated with damage to soya beans exported from South America. These claims tend to recur on an annual basis associated with the harvest cycle of soya beans. Similar claims can also occur with other grain cargoes.”

With autonomous ships likely to enter service soon, LR has set out the ‘how’ of marine autonomous operations in a new ShipRight procedure guidance. The guidance describes autonomy levels (AL) ranging from ‘AL 1’ through to ‘AL 6’ denoting a fully autonomous ship design with no access required during a mission.

The ‘AL’ system of levels provides clarity to designers, shipbuilders, equipment manufacturers, ship owners and operators, enabling accurate specification of the desired level of autonomy in design and operations and paves the way to a clearer understanding of the investment opportunity/risk equation.

Danish ships to be issued with digital certificates

Posted on by News Hound

The Danish FlagDenmark is set to become an international frontrunner as ships flying the Danish flag are to be fitted with digital certificates. As one of the first countries in the world to make this move, Denmark has put an end to the 100 years old tradition of certifying ships by means of old-fashioned certificates on paper.

Until now, the certification has been carried out by printing, stamping and signing paper certificates and subsequently sending them around the world to be kept on board ships.Digital certification or electronic certification which is the term used internationally – will put an end to these cumbersome procedures, reduce administrative workloads and pave the way for further maritime digitalisation.

MAIB releases its report on the grounding of the Hamburg cruise ship

Damaged propeller from the grounding of the Hamburg cruise ship

At 1328:21 on 11 May 2015, the Bahamas registered Hamburg cruise ship grounded on charted rocks near the New Rocks buoy in the Sound of Mull, Scotland. The accident caused considerable raking damage to the hull and rendered the port propeller, shaft and rudder unserviceable.

There were no injuries and the vessel continued on its passage to Tobermory.

The investigation found that, having been unable to enter Tobermory Bay on arrival, the passage plan was not re-evaluated or amended. Combined with poor bridge team management and navigational practices, this resulted in the vessel running into danger and grounding. Despite the loud noise and vibration resulting from the grounding, the bridge team did not initiate the post-grounding checklist, no musters were held and neither the managers of the Hamburg cruise ship, nor any shore authorities were notified of the accident.

Japan P&I Club warns of increasing ignition during petcoke loading in Venezuela

Posted on by News Hound

Japan P&I Club LogoPetcoke (petroleum coke) is a byproduct of the oil refinery coking process that produces low-cost fuel, often with a high sulphur content. Petcoke may also be known as green delayed coke, sponge coke, needle coke, delayed coke or raw coke-fuel grade. Petcoke is over 90 percent carbon and emits 5 to 10% more carbon dioxide (CO2) than coal on a per-unit of-energy basis when it is burned. As petcoke has a higher energy content, petcoke emits between 30 and 80 percent more CO2 than coal per unit of weight.

First in-tank drone survey undertaken by DNV GL

Posted on by News Hound

A in-drone surveyThis week, DNV GL announced that it had completed its first drone survey. This most recent maritime application for drones demonstrates a growing interest in the technology that has, over the last year, seen applications emerging across merchant, naval and research fleets around the world.

The survey took place on the MV Apollo, a chemical tanker owned by Carl Büttner Shipmanagement in Germany. Two DNV GL surveyors used the drone survey to inspect 14 tanks over a period of two and a half days.
