RINA tackles ocean noise pollution

DOLPHIN notation will be applicable from July 2014 International classification society RINA has acted to tackle noise pollution of the seas by developing a voluntary notation which will apply to vessels for which efforts have been made to mitigate underwater noise.Paolo Moretti, Head of the Marine Business Line, RINA Services, says, "Noise is the new pollution. The international community has raised concern that the underwater noise generated by commercial shipping may have negative consequences on marine life, especially marine mammals. RINA is tackling that with a new voluntary notation, DOLPHIN, which gives shipowners a clear option to specify commercial vessels which have implemented solutions to minimize radiated underwater noise."IMO has recently published MEPC Circ. 833 "Guidelines For The Reduction Of Underwater Noise From Commercial Shipping To Address Adverse Impacts On Marine Life" which sets out advice on design and operational solutions that may be adopted to reduce underwater radiated noise.The International Organization for Standardization (ISO) has developed the (ISO/PAS) 17208-1 - Acoustics - Quantities and procedures for description and measurement of underwater sound from ships - Part 1: General requirements for measurements in deep water and ISO/DIS 16554 - Ship and marine technology - Measurement and reporting of underwater sound ...

RINA launches voluntary notation for Eco-ships

Class notation granted to vessels which contribute in environmental performance International classification society RINAhaslauncheda new goal-based classvoluntarynotation, GREEN PLUS. The voluntary notation will be based on an environmental performance index which covers all aspects of the vessel's impact on the environment, including carbon emissions.RINA's GREEN STAR notation has become a watchword for environmental excellence in shipping, anticipating the requirements of MARPOL and other relevant legislation, and placing owners and operators in an advantageous position. Now, with GREEN PLUS, RINA introduces a new class notation only to be granted to new vessels which make a significant investment in design solutions, onboard equipment, and operational procedures which contribute to an improvement in environmental performance beyond the minimum levels required by regulation.Design solutions and onboard equipment include anything which reduces the risk of pollution, or which lowers fuel consumption and air emissions. Innovative engine design, alternative fuels, high-efficiency propellers, optimal hull design and bio-degradable oils all fall into these categories.Operational procedures covered by a GREEN PLUS notation include those which ensure that design solutions and onboard equipment are correctly used, voyage planning programmes resulting in reduced fuel consumption and emissions, or training courses designed to increase the environmental awareness of officers and crews.Antonio ...

Cruise safety dominates regulations following Concordia tragedy

RINA's highlights on cruise ship stability challenges Market conditions as well as green regulations have been pushing the cruise lines to further explore energy efficiency measures and technology to reduce their eco-footprint.RINA's conference on design and operation of passenger ships in November last year, highlighted some of the challenges faced by the passenger shipping industry in terms of their approach to assessing cruise ship stability, as well as practical steps that can be taken to improve evacuation procedures in the event of a casualty and risk assessment for passenger ships.David Ridden, principal consultant at Burness Corlett Three Quays, highlighted the practical difficulties of assessing the stability of cruise ships, which have been increasing in size and in numbers during the past 20 years.The growth in passenger numbers has occurred at the same time as regulatory changes aimed at ensuring adequate margins of stability in intact and damaged conditions.He maintained that the: "statutory requirements for confirming the accuracy and reliability of the lightship properties remain largely unchanged and do not reflect the increased risk presented by ever larger passenger ships."As cruise ship operators seek to improve the appearance of their ships and the amenities on board, this results in potential weight ...
