Terrestial and Underwater Radiated Noise from Powerships: Testing and Evaluation

The increase in shipping activity globally has resulted in an increased awareness of impacts on the marine environment. Effects of noise pollution, especially on marine life, have become highly prominent. Marine life is extremely sensitive to noise pollution. Due to their extreme reliance on underwater sounds for basic life functions like searching for food and mate and an absence of any mechanism to safeguard them against it, underwater noise pollution disrupts marine life (Singla, 2020). In short, marine animals depend on sound to live, making and listening to it in various ways to perform various life functions (US Bureau of Ocean Energy Management, 2014).

Noise travels much more in water, covering greater distances than it would do on land while travelling through air. Underwater sound has both pressure and particle motion components and hearing can be defined as the relative contribution of each of these sound components to auditory detection (Popper AN, 2011). Sounds radiated from ships are among the underwater noise sources. Among shipborne Underwater Radiated Noise (URN) sources are the following:

  • Propeller’s rotational turn and the blades hitting to water flow lines
  • Propeller’s cavitation
  • Ship hull structure’s interaction water (fluid-structure interaction)
  • Mechanical noises from onboard machinery

All of these noise sources are radiated to underwater from ships, especially when the ship speed is at higher rates, i.e. above 15 knots.

When a Powership is considered, out of the 4 aforementioned noises, only mechanical noise sources are of concern as there are no noises that emanate from the other three sources because the Powership is docked. Mechanical onboard noises are still of concern and therefore need to be evaluated and tested for the assessment of their potential negative effects to marine life.

GDS Engineering R&D has the capability for measuring the underwater radiated noise and assessment of the results based on the effect to the sealife in the region.

Categories of Maritime (Ship) Accident Types and Research Studies

Categories of Maritime (Ship) Accident Types

Lloyds Maritime Information Services (LMIS) has a casualty database which divides the maritime (ship) accidents into the following categories:

1. Foundered – includes ships which sank as a result of heavy weather, leaks, breaking into two, etc, and not as a consequence of other categories such as collision etc.

2. Missing vessel – includes ships that disappeared without any trace or witnesses knowing exactly what happened in the accident.

3. Fire/explosion – includes ships where fire/explosion is the first event reported, or where fire/explosion results from hull/machinery damage, i.e. this category includes fires due to engine damage, but not fires due to collision etc.

4. Collision – includes ships striking or being struck by another ship, regardless of whether under way, anchored or moored. This category does not include ships striking underwater wrecks.

5. Contact – includes ships striking or being struck by an external object, but not another ship or the sea bottom. This category includes striking drilling rigs/platforms, regardless of whether in fixed position or in tow.

6. Wrecked/stranded – includes ships striking the sea bottom, shore or underwater wrecks.

7. War loss/hostilities – includes ships damaged from all hostile acts.

8. Hull/machinery damage – includes ships where the hull/machinery damage is not due to other categories such as collision etc.

9. Miscellaneous – includes lost or damaged ships which cannot be classified into any of the categories 1 through 8 due to not falling into any of the categories above or due to lack of information (e.g. an accident starting by the cargo shifting would typically be classified as miscellaneous).

Above is also referenced in Wartsila website. Man Over Board (MOB) event, a person falling into water, is not referenced in the above listing.

 

However;

IMO accidents website, Global Integrated Shipping Information System (GISIS), refers to Man Over Board as another accident type, which may end with a death or injury. We would like to refern the following two of our publications for the details of MOB and Collision accident types:

Title: Maritime Investigation Reports Involving Man-Over-Board (MOB) Casualties: A Methodology for Evaluation Process, Turkish Journal of Maritime and Marine Sciences, Vol: 5 No: 2 (2019) 141-170. Authors: Orhan Gönel and İsmail Çiçek. Click this link for more information...

    MIL-STD-810H Training: “Tailoring is Essential”

    MIL-STD-810H, US DOD Test Standard, starts with an important phrase at the beginning paragraph of each of the 28 test methods: “Tailoring is Essential.” It is therefore crucial to understand what this means and how to tailor the test methods for specific equipment, considering the platform, mission, and environmental requirements.

    GDS Engineering R&D provides MIL-STD-810H training online or onsite. Performing operations in various parts of the world, we have been providing this course to the defence industry strategists, leaders, program managers, projects managers, designers, and test engineers for more than 10 years. With long years of background in test projects in the USA and Turkey, Dr. Cicek, the main lecturer of this training, explains the tailoring concepts with specific examples.

    This course provides with information and knowledge of experience on how to develop Concepts of Operations (CONOPS) document and Lice Cycle Environmental Profile (LCEP) to derive operational therefore test requirements for the Equipment Under Test (EUT). Understading the tailoring part of MIL-STD-810H is probably the most important aspect of this test standard training, due to the following reasons:

    • Developing a test plan for MIL-STD-810H equipment testing might be a confusing and time consuming process.
    • Training will provide an understanding into why and when CONOPS document is needed and how test requirements are established along with Mission and Environmental profiles of the EUT. These are all covered by both presentations and specific product examples through discussions during the training sessions.
    • In test method discussions, the instructor discuss “what items” (i.e. test levels) and “how” they will be tailored with specific examples.

    Test methods, i.e. temperature, humidity, temperature shock, require mission and environmental profiles are established for successfully determining the test levels, durations, and criteria for pass or fail.

    Consider the following for tailoring

    A Generalized Task Statement for Tailoring: Condider the environmental effects. An example list is provided with a list below. Develop exposure curves considering exposure scenarios. For this, use/develop CONOPS document and generate a Life Cycle Environmental Profile (LCEP).

    • Environmental effects (temperature, humidity, icing, etc.) to the equipment in different operational modes: i.e. transportation, operation, and stand-by. Condider these effects with scenarious and develop exposure curves.
    • Equipment vulnarabilities under the environmental/operational conditions.
    • Effects caused by the platform operations (vibrations, shock, etc.)
    • The effect due to the platform environment; various conditions in the section the equipment will be operating. For example, the equipment might be exposed to fluid contamination in the section where it will be installed.
    • Equipment’s effect to the environment and systems (EMI, vibrations, fluid contamination, fire and flammability, etc.)
    • Consider risks of operational breakdowns with “what if” scenarios.
    GDS MIL-STD-810H Training: Scope and Contents
    • A good understanding of product testing in view of MIL-STD-810G/H and other relevant military standards.
    • Overview of Systems Engineering, V&V, and Concepts of Operations (CONOPS) document.
    • Establishment of Test Requirements and Test Plans.
    • Test Procedures, Scheduling, Implementation, and Test Reports.
    • Tests are covered in detail per MIL-STD-810. Altitude, temperature, humidity, shock, vibration, acceleration, salt fog, explosive atmosphere, etc..
    • Some of the MIL-STD-810H test methods are covered briefly; however, we ensure all questions are answered for each test method.
    • Cases studies, sample reports and discussions on issues.
    • Design issues and test failure discussions.
    • Risk management for test results and acceptance criteria.
    • Design Recommendations.

    Abstract

    Our research study indicates that, over the past few decades, the expected decrease in the number of maritime accidents has not occurred. The statistics show the collision and contact types of marine accidents have always been the most frequent. Primary causes that contribute to ship collisions were collected from 513 collision accidents reported since 1977, which is the date the Convention on the International Regulations for Preventing Collisions at Sea, 1972 (COLREGs) came into effect. The root causes of ship-to-ship collisions were determined statistically. Qualitative and quantitative analyses were carried out using the Fault Tree Analysis (FTA). This provided the probability and importance of the primary causes contributing to the ship collision accidents and defined minimal cut sets. Results show that the violation of the COLREG Rules is the most important and effective factor for collision accidents. Therefore, further analysis was conducted and the results showed which type of COLREG Rules mostly violated statistically. The primary causes were also examined by Multiple Correspondence Analysis, and it was determined that maneuvering and perception errors were the most effective factors in collision accidents. The results represent the cause statistics of the ship-to-ship collision accidents that occurred in the last 43 years. Considering the collision accident reports data, our results show %94,7 of collision accidents are related to human error.
