World s first solar-power-assisted vessel further developed

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 ...

Replacement of IAPP Certificate

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.

ClassNK has started to test and certify radiation levels on ships

Japan attempts to reassure owners who refuse to call at ports in Yokohama and Tokyo The Japanese class society has kicked off a monitoring campaign to alleviate fears over ship contamination.ClassNK has started to test and certify radiation levels on ships as Japan attempts to reassure owners who are refusing to call at ports in Yokohama and Tokyo in fear of contamination from the damaged Fukushima Daiichi nuclear plant.The movestarted one month after the earthquake and tsunami and at a time when cruiseship operators are not calling in Tokyo Bay and as many as 20 boxship calls in the area have been cancelled.Although the Tokyo-based Japanese classification society does not have any radiation-testing equipment itself, it is subcontracting the work, counter-signing the documentation and then offering its own certification.

Guideline for measurement of dose rate for ships in Japanese ports

Information on radiation dose rate The need for the information on radiation dose rate for ships from Japan has been on the increase at the ports outside Japan since the aftermath of damage on the Fukushima nuclear power plant caused by the earthquake on 11 March 2011 and subsequent Tsunami.In the face of this need, Japanese Government (MLIT: Ministry of Land, Infrastructure, Transport and Tourism) has developed the guideline on radiation measurement for ships in order to provide foreign port authority with proper access to accurate data.Attestation for radiation dose rate will be issued if the measurement is conducted based on the guideline. ClassNK is requested by MLIT to issue an attestation in case where the measurement is conducted in Port of Keihin Yokohama Area. In this context, ClassNK issues the attestation for ships of which radiation dose rate is measured in line with the guideline in Port of Keihin Yokohama Area. ClassNK is also ready to issue an appraisal report for ships that measurement is carried out in Japanese ports other than Yokohama area. The attestation issuance procedures are shown below.A) The radiation dose rate measurement operator is to be arranged by the applicant.B) The applicant requests ClassNK (the ...
