New class notations aim to improve stern tube bearing performance

Posted on by News Hound

A ship tube bearingDNV GL has revised its class rules for single stern tube bearing installations and introduced two new class notations, “Shaft align(1)” and “Shaft align(2)”, to help customers better manage the risk of stern tube bearing failure. The new class notations can be assigned to both newbuilds and vessels in service in conjunction with propeller shaft withdrawal.

The classification rules covering shaft alignment are formulated to achieve an acceptable distribution of loading on the shaft bearings and lubrication of the aft bearing, taking into consideration the bending moment induced by the propeller during operation. However, during turning manoeuvers at higher ship speeds, exaggerated propeller bending moments can occur, potentially resulting in a reduced shaft- Continue reading “New class notations aim to improve stern tube bearing performance”

Operators and surveyors urged to test cargo hold bilge systems to minimise claims

The UK P&I Club has reminded those working in the marine industry that significant insurance damage claims can result if a bulk cargo is damaged due to the leakage of the bilge system into a loaded bulk cargo hold.

To reduce the chance of such cargo damage, operators and surveyors are advised to inspect and test the cargo hold bilge system as part of the routine pre-loading checks of the cargo holds.

Inspection and testing of cargo hold bilge system non-return valves should be included in routine pre-loading checks of the holds. These non-return valves may not be seated tightly, because of the Continue reading “Operators and surveyors urged to test cargo hold’s bilge system to minimise claims”

Rolls-Royce will supply the tug boat sector with its first hybrid propulsion arrangement for installation to a multi-purpose tractor tug undergoing construction for Baydelta Maritime LLC. The vessel is being built at Nichols Brothers Boat Builders, in Washington State, U.S.A.

The order represents the first hybrid tug using proven Rolls-Royce hybrid technology, the first installation of a hybrid system for Nichols Brothers and the first hybrid tug designed by Jensen Maritime, Crowley Maritime Corp’s Seattle-based naval architecture and engineering firm.

The 100-foot long tug will feature the same ship assist and tanker escort capabilities of existing Delta Class harbour tugs but with greatly improved towing performance. The Rolls-Royce hybrid system enhances the Continue reading “Rolls-Royce to provide tug sector with its first Hybrid System”

Speaking at the UK Chamber of Shipping’s Annual Dinner, Chris Grayling MP, UK Secretary of State for Transport, contributed to a “radical” vision that will support the nation’s maritime industry for the future.

The UK Government will cooperate with industry bodies and businesses, and will publish a call for evidence that will provide a framework for engagement. An expert panel will also be appointed, Mr Grayling said.

“We need a clear path for the future, we need a strong partnership between this industry and government – and we’re calling it Continue reading “UK Transport Secretary proposes Maritime 2050 vision”

To address the evolving safety and security needs of modern ports, Vancouver based naval architects and marine engineers Robert Allan Ltd., and international marine technology specialist Kongsberg Maritime are collaborating on the development of a radically new remotely-operated fireboat that will allow first responders to attack dangerous port fires more aggressively and safer than ever before.

The un-crewed RALamander fireboat will offer in-close firefighting and ‘eye in the fire’ capability that keeps marine firefighting professionals out of harm’s way. Fires involving containers, petrochemicals, shore-side structures or vessels can be attacked more quickly Continue reading “Remotely operated fireboat set to tackle fires in ports”

In UK P&I Club’s latest ‘Lessons Learned’ series of case studies, Captain David Nichol presents the case regarding improper maintenance of ventilation after a maintenance operation, which could have led to the deaths of two surveyors during a third party survey on the emergency fire pump.

About the incident

During a third party survey, the surveyor made a request to test the emergency fire pump, which was arranged with the assistance of the chief engineer. The emergency fire pump was located in a recessed well in the steering gear compartment, approximately 3 metres deep and accessed by an inclined stairway. At the start of the test, the surveyor asked to observe the pump being started locally and operating before proceeding on deck to check the hoses rigged fore and aft.

Shortly after descending into the fire pump well, the chief engineer urgently ordered the surveyors to get out and by the time both men reached the steering compartment deck, they were Continue reading “Improper maintenance could have led to double fatality says UK P&I Club”

Cargo damage caused by leaking hatch covers

Cargo damage caused by leaking hatch covers

The Swedish P&I Club has described the case of cargo damage on a bulk carrier caused by water ingress, as a result of the poor condition of hatch covers.

The incident

The bulk carrier had seven cargo holds which had been fully loaded with soybeans. The vessel had side rolling cargo hatch covers. For six days, the vessel encountered heavy weather of force 9 on the Beaufort scale, causing the vessel to pitch and roll heavily. It were repeatedly washed over by seawater.

All were opened when the vessel was at anchor and waiting for an available berth. This was to ensure the vessel was gas free since fumigation had been carried out in all cargo holds at the loading port. When the cargo hatch covers were removed, it was found that Continue reading “Cargo damage caused by leaking hatch covers”

The Taskforce brings together leaders from across the maritime sector to identify practical steps to increase the number of women in maritime, and crucially within senior roles across its shipping, ports, marine and business services industries.

Achieving a balanced workforce at all levels in the maritime sector will undoubtedly improve culture, behaviour, outcomes, profitability and productivity.

During London International Shipping Week, then Maritime Minister Rt Hon John Hayes MP called for industry to address gender imbalance in the sector. Government are represented on the Taskforce.

The Taskforce will make a series of recommendations and utilise Continue reading “Maritime UK has established a Taskforce to increase the number of women within the UK maritime sector”

Confusion surrounds antifouling paints which have not been banned in the UK

There is still confusion regarding the future availability of antifouling paints says the British Coatings Federation’s Marine Coatings Group.

The group has produced an explanatory note that it says is intended to provide clarity on the Biocidal Products Regulation, making it clear that antifoul paints – including copper-based antifoul – have not been banned.

“Antifouling paints containing co-biocides also known as ‘booster’ biocides have not been banned,” added Trevor Fielding, regulatory affairs manager at the BCF.

“The industry and the regulators are working hard to make the implementation of Continue reading “Confusion surrounds antifouling paints which have not been banned in the UK”

Bilge system back-flow causes significant cargo damage

Writing in the latest publication by UK P&I Club, Captain David Nichol cites a case history describing a cargo damage case involving a bulk carrier caused by insufficient maintenance of the bilge system valves and the crew’s wrong estimation of the ingress alarm system.

The incident

Prior to loading a full cargo of bulk minerals the cargo holds were cleaned and tested successfully for watertight integrity. In addition, the efficient operation of the cargo hold bilge pumping system and water ingress alarms was also verified. A few days after departure from the loading port, the water ingress alarm for no.2 cargo hold was activated. However, when the hold bilges were sounded by the crew, they appeared to be dry and it was therefore assumed that the ingress alarm system was defective. Daily hold bilge soundings continued to give no cause for concern. At the discharge port, wet cargo was revealed at Continue reading “Bilge system back-flow causes significant cargo damage”
