4 INTRODUCTION

5 MOTIVATION & GOAL Noise complaints from (seagoing) ships at berth are a growing issue in a lot of ports due to: port and residential areas are getting closer trend of more and larger vessels. The project will provide insight in the noise from seagoing vessels at berth (and at anchor) will provide tools to support a sustainable port development by reducing the nuisance of noisy vessels. 4

8 SCOPE & OBJECTIVES Scope: Sea-going ships at berth/anchoring Noise from the auxiliaries and activities or any other component or equipment (e.g. generators,..) belonging, placed or installed on ships Noise produced by equipment attached to the cargo (e.g. reefers) is also included. Project objectives: Get more insight into noise problems related to ships What type of vessel and source(s) of these vessels are the causes of noise nuisance perceived by residents Enhance knowledge of measuring and quantifying ship noise Identify problems met with legislation, regulations or policies Ways to mitigate noise nuisance. 7

9 DELIVERABLES & PLANNING PHASES Report with overview of laws, regulations, policies or governance Best practice guide with effective measures, including noise awareness methods Measurement protocol and guidelines for noise labelling of ships Roadmap for implementation of measures and noise labelling in e.g. ESI Q1 17 Final Phase Q3-Q4 18 Inventory Phase Q2-Q4 17 Preproject Implementation Phase Design Phase Q3 17 Q1 18 Congress Q1-Q2 18 8

10 MEASUREMENT PROTOCOL

11 MEASUREMENT PROTOCOL The goal is: the development of a uniform, worldwide applicable measurement standard to measure, analyse, evaluate and classify individual ships with respect to their airborne noise emission in ports to ensure comparable ship noise measurements in all ports around the world to create a basis for a comparable evaluation of ship noise that can be the origin for a ship noise classification system. 10

12 SHIP CLASSIFICATION & SOUND SOURCES Classification includes two different types of measurements: 1. Measurements in a certain distance of a ship 2. Measurements of single sound sources on board of a ship. Additional measurements in the preliminary project test phase (right now). Ship types: Container ships Cruise ships Tankers RoRo/RoPax Bulk carriers General cargo service vessels Relevant sound sources on board: Funnel outlet(s) of the auxiliary engine(s) Opening of ventilation in- and outlets Cooled containers / reefers Pumps on deck 11

13 1) MEASUREMENTS IN A CERTAIN DISTANCE TO A SHIP give an overview of the overall sound emission of the ship, can indicate the presence of low frequency noise, can be used for comparisons with the sound measurements on board of the ship. Methods: Horizontal distance dh = Measurement height of at least hm = 6 m above quay ground 12

14 2) MEASUREMENTS ON BOARD OF A SHIP will be performed to identify the most dominant sound sources on a ship will give an overview of the sound power level of the individual sound sources on board of the ship. Methods: Measurement of each individual sound source Meandering averaging over the surface Surface method in accordance with ISO Measurements according to ISO 3746 or ISO Additionally DIN (funnel outlet) Restriction: Up to three representative sound sources for each source type (e.g. 3 cooling containers) 13

15 3) PRELIMINARY TEST PHASE Measurements undertaken by participating Neptunes ports to verify the practicability of the MP (during April to June 2018) Include: maneuvering sound emissions of a ship Additional measurement positions in a certain distance from the ship Additional sound measurement position(s) at the funnel outlet Additional sound measurement laterally of the container stacks A sound propagation model Will be revised and shortened during summer

16 DOCUMENTATION OF RESULTS Measurement report of each measurement (in.docx and.pdf) Information to be documented (standardized measurement report format): Technical information of the ship Operating conditions Weather information Information on the measurements (e.g. microphone positions, sketches of sound sources) Acoustic information (graphs and tables) Additional information 15

17 NOISE LABEL

18 A noise label: MOTIVATION & GOAL can be a classification system to evaluate and compare different ships and to learn about the port specific ship fleet composition can be a mitigation possibility to reduce noise annoyance e.g. by means of incentive/penalty system or by means of development of a port berthing site policy creates awareness and contact with the industry, but should also calm down residents needs to follow a standardized measurement procedure to a given load condition and shall be easy to understand can address: environmental issues (e.g. national regulations, noise model) annoyance port/terminal license 17

19 IDEAS FOR NOISE LABELLING Use of total sound power level of a measured ship and/or Use of sound power levels of major noise sources (e.g. funnel exhaust, pumps) Should include penalties for: low frequency disturbance tonality intermitting noise Combination of several parameters Noise label needs to take care of/needs to be based on, e.g.: Electric load of the auxiliary engine(s) DWT Sound reduction measures applied (e.g. silencer in exhaust pipe) Number of reefers on board. Information available trough Measurement Protocol 18

20 Points EXAMPLE OF A NOISE LABEL Lw [db(a)] Ideas for noise label: Point or (100 / 50 / 0 points) Class system (A / B / C or good / mediocre / bad) + points for low frequency disturbance (db(c)-db(a)) + points for ship type / class / engine load + points for environmental issues in the specific port = Assign number of points to noise classes (3 classes) 19

21 WHAT LABEL DO PORTS WANT TO HAVE? Global label? Needs to be applicable in every port, but we have divers operating conditions of ships within each calling port (-> diesel generator load) Might be affected by local conditions/disturbers (landside measurements) Port label? Can include local regulation/local environmental issues Label system that can be included (and advertised) by external partners (e.g. ESI, Green Award, Certifiers)? Newbuilds/existing ships? How to get shipping companies involved? Best way to mobilize large shipping companies (e.g. Maersk, Hapag-Lloyd) How to guarantee data quality? Organization of noise label will take some time! We ll se what is the result of the MP test phase! 20

22 CONCLUSION

23 Long-term Neptunes goals: TO CONCLUDE supporting a sustainable port development with less noise nuisance stimulating the development and use of quieter ships supported by a noise labelling system for ships and incentive program in ports. For Neptunes to become a success we need your support: additional members for the resonance group a widespread implementation of the project results. 22

24 NEPTUNES FOLLOW UP April June 2018: Measurement protocol test phase/ship noise measurements in participating Neptunes ports/final adjustments of the measurement protocol June - August 2018: Evaluation of MP and measurement results, assessment of results for noise classification possibilities April August 2018: Contacting ship owners, certifiers and incentive providers like ESI, Green Awards etc. for collaboration possibilities May September 2018: Development of a Best Practice Guide (includes state of the art noise mitigation measures etc.) Late autumn/early winter: Neptunes conference with project output presentation 23
