New case study by American P&I Club reminds that lubricating oil maintenance is critical

If there is one standout cause for failures of main and auxiliary engines, it is through inadequate monitoring and maintenance of the condition of lubricating oil – literally the life-blood of any engine. The American P&I Club has issued a new case study taking into account best practices in the prevention of shipboard machinery failures.

The case study incident:
The medium speed main engine of a bulk carrier suffered a turbocharger failure whilst on transatlantic passage to New York. The engine had then labored for several days with a non-functional turbocharger creating very poor combustion and black exhaust smoke. Whilst in port and undergoing turbocharger repairs the attending surveyor recommended that lubricating oil samples be taken from the main engine for analysis. It wasn’t done, and several days later during another loaded passage, the main bearings and then the crankshaft failed leading to towage, large general average costs and extensive disputes over seaworthiness.

ClassNK issues amendment of rules for ship windows

The Control Window of a shipClassNK has investigated behaviour of waves acting on windows located considerably above the freeboard deck of ships where the navigation bridges are located forward of the midship, such as onboard Ro-Ro cargo ships. Based on the investigation results, ClassNK has issued amendment of rules for ship windows.

It has been found out that there is possibility waves can hit the windows located considerably above the freeboard deck due to waves rolling over the foredeck and running up along the front walls, even though the wave height may not be so high that the wave directly reaches the windows. In fact, cases have been confirmed in which navigation bridge windows seem to have been damaged by the aforementioned phenomenon.

What can be done about the contamination of GMO crop cargo

The West P&I Club has reproduced an article written by Dr. Tim Moss and Dr. Daniel Sheard of Brookes Bell entitled “Contamination with GMO crop cargo – What can be done?”. The article discusses the science behind GMO crops, along with the ramifications of being found to have GMO contaminated cargo onboard. It also looks at the practical measures that can be taken to prevent a cargo becoming contaminated and to prevent the spoilage of a cargo that has been rejected due to GMO contamination.

Problems for the carrier may arise due to traces of GMO crops being found in a subsequent cargo due to ineffective cargo hold cleaning, and the cargo is rejected at the discharge port, or where a cargo found to contain GMO remains onboard the vessel for an extended period before it is possible for it to be discharged, and the condition of the cargo begins to deteriorate.

Fitting bulldog grips incorrectly may cause cargo damage

Two men securing a containerThe single most predominant factor associated with the failure of cargo lashings is the incorrect application of bulldog grips. Tony Watson, Risk Assessor at UK P&I Club has issued some advice on the correct application of bulldog grips in order to minimise damage to cargo.

Bulldog grips are commonly used for the securing of project cargo, both under and below deck. They are also used on ships on mast stays and crane wires, although swaged connections are now more common. Failed lashings can result in significant damage to cargoes and can also pose significant risk to the wellbeing of crew members and the safety of the ship.

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

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

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

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.

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

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.”

Wärtsilä’s hybrid battery technology to be used on new Wightlink flagship ferry

A ship under construction at Cemre shipyard for UK operator Wightlink will be the first ferry to employ Wärtsilä’s technology that uses batteries to manage engine load fluctuations.

The use of batteries in conjunction with four six-cylinder Wärtsilä 20 generating sets – controlled by a 690v main switchboard, an integrated automation system and a power management system also supplied by the Finnish company – is expected to improve fuel efficiency and reduce emissions while lowering noise levels.

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

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.
