For measuring and evaluating the noise and vibration on vessels ClassNK has issued a new Noise and Vibration Guideline for measuring and evaluating the noise and vibration on vessels.The guideline address the growing demand for new standards for noise and vibration on commercial vessels and provides detailed requirements for measuring and evaluating noise and vibrations in crew accommodations and machinery rooms, as well as establishes new notations for ships that comply with the new requirements.As efforts to improve the working conditions of seafarers have come to the forefront over the past several years, vibration and noise in accommodation areas have become an increasingly important topic.At the same time, as awareness of the detrimental effect that vibration can have on the reliability and safety of vessels' machinery and equipment has grown, research is increasingly focused on developing new countermeasures for machinery vibration.With the results of many such research projects just now being released, ClassNK felt the time was ripe to release a new set of standards for the maritime industry."This new Guideline," said ClassNK development department general manager Toshiyuki Shigemi, "incorporates the results of the latest research on noise and vibration on board ships, along with the latest developments in international ...

IACS chairman & ClassNK head Noboru Ueda During his recent India visit, Noboru Ueda , chairman of International Association of Classification Societies (IACS) and head of ClassNK, talks to V Ayyappan on world shipping scenario. Excerpts from the interview.How healthy is global shipbuilding industry today?Much like the shipping industry, the shipbuilding industry is very cyclical, and in my more than 40 years in the maritime industry I have seen several market downturns like this one.With that said, while the current downturn presents a challenge for the industry, it does not compare to previous downturns such as occurred in the late 1970s and 1980s. While these are still not the best of times for shipbuilders, I am very optimistic about the future of the shipbuilding industry. What made the owners overbook which led to the present crisis? How long will the over capacity situation last?While it may be true that an oversupply of new vessels is one of the reasons behind the current slump in charter rates, I think we should not overlook the lingering effects of the economic crisis. The health of the shipping industry depends on the growth of world trade, and the slowed growth of the world's leading ...

Called "Primeship-HULL" ClassNK has developed and released advanced calculation software for IACS Common Structural Rules (CSRs) called "Primeship-HULL (CSR)".Rule CalculationsThe Rule Calculation Systems provide the necessary information and report outputs for CSR application. The Rule Calculation Systems can provide you with cross section calculations, hull girder strength assessment, local strength assessment, fatigue strength assessment and buckling strength assessment, etc. based on inputs of arrangements and gross scantlings of cross section as shown in the left hand figure below.Direct Strength AnalysisThis is a direct strength calculation tool that can conduct Finite Element Analysis (FEA) and provide strength assessment as shown in the right hand figure below. The system is based on MSC.Patran, and strongly supports structural assessment work by providing design loads, boundary conditions, etc. in accordance with the requirements of CSR to carry out a series of direct strength analyses.You can view further information, by clicking here.Source: ClassNK

Auriga Leader to be fitted with BWM system and adapted to use low-sulfur fuel The power generation and endurance of the photovoltaic panels on Auriga Leader have been undergoing shipboard tests since the completion of the vessel on December 19, 2008.The tests have shown that providing a stable power supply from the photovoltaic panels is difficult because even a slight change in the weather has a significant influence on the amount of power generated.It was also found that attempting to make the solar power system bigger to gain more output and to increase its dependency could result in problems with regard to stable operations due to fluctuations in the power supply.The hybrid power supply system has been studied since fiscal 2009.NYK Line and MTI, with the aim of curtailing CO2 emissions, have pursued a stable onboard power supply in case an unstable renewable energy source such as solar power were to be adopted; KHI has been working to develop a hybrid power supply system for vessels through the use of its self-developed large nickel hydrogen batteries known as Gigacell?; and ClassNK is supporting these projects as part of assistance provided through a joint research scheme based on industry demands.Charging and ...

Due to change in procedure for completing Supplement As already advised in ClassNK Technical Information No. TEC-0771 dated 13 May 2009, in accordance with Reg. 14 of MARPOL Annex VI, the sulphur content limit value for a fuel oil used outside of an Emission Control Area will be changed from 4.50% m/m to 3.50% m/m on 1 January 2012 and will be effective thereafter.Required sulphur content limit values are described in section 2.3 of the Supplement to the IAPP Certificate using a check box form. So far, only the check box for the sulphur content limit value which is applicable at the time of issuance of the Certificate has been ticked off. Therefore, whenever a new sulphur content limit values is enforced, the IAPP Certificate needs to be replaced each time.However, the IMO MEPC 61 agreed that section 2.3 of the Supplement should be completed on the basis of all available options, with a view to avoiding the need for repeated re-issuance of the Supplement, as the various given dates are passed. In accordance with this agreement, ClassNK will change the procedure for completion of section 2.3 of the Supplement and tick off all the check boxes which may be ...
