SHIP RECYCLING


EU Ship Recycling Regulation Brief - Impact Overview

1.     Regulations

EU Ship Recycling Regulation ("EU SRR") – means Regulation (EU) No 1257/2013 of the European Parliament and of the Council of 20 November 2013 on Ship recycling and amending Regulation (EC) No 1013/2006 and Directive 2009/16/EC (EU SRR).

It requires EU flagged ships to be recycled at approved yards on the EU list. EU yards are allowed on the list without fulfilling uniform criteria. In contrast, non-EU yards have to be inspected by European Commission appointed auditors according to precise criteria before inclusion on the list.

2.     Ship Recycling Facility/ Shipbreaking Facility/Yard/Scrapyards

The owners must do sufficient due diligence and follow up in connection with disposal of Ships at the end of life and sale of Ships expected to be recycled shortly. In addition, shipowners must ensure that Ships sold for recycling are recycled according to the international regulations and standards by:

     Using a recycling yard on the European List with a compliance statement from a reputable specialist organization concerning the EU SRR

     Preparing the Ship for responsible recycling through mapping all hazardous material, arranging necessary inspections, obtaining the required certificates, and emptying, cleaning and venting the Ship as per the EU Ship Recycling Regulation requirements.

     Using yards that can document responsible recycling through a Ship Recycling Facility Plan and a vessel-specific Ship Recycling Plan.

     Using yards with fixed arrangements for collecting and processing hazardous or contaminated waste and proper emergency response capabilities to document good HSE and labour policies.

     Following up the recycling process through inspections and reporting.

     Securing their rights to follow up, stopping work when necessary etc through the contractual agreements entered into at the sale of a vessel at the end of life.

     Shipowners should obtain and maintain IHMs for vessels in the fleet throughout their lifetime.

              2.1  List of yards under regulations 

As of 21/01/22, the European List of Ship recycling facilities currently contains  43 yards, including 34 yards in Europe, 8 yards in Turkey and 1 yard in the USA.

The world's two biggest ship scrap yards by capacity, China's Zhoushan Changhong International Ship Recycling and Jiang Xiagang Changjiang Ship Recycling Yard, have applied to include their facilities in the future EU list Ship Recycling Facilities.

Lloyd's Register (LR) has commenced its initial verification of the yards' ship recycling facility plans (SRFP) and will help them complete their applications to the European Commission.

            2.2  List of yards outside of regulation

             Around 85 per cent of the world's shipbreaking activities occur in Bangladesh, China, Pakistan                                                 and India

3.     Cost /Earning

    3.1 Cost inside EU regulation

Cost per ton for second-hand metal from ship scraping per country as of 10.01.2022 following  EU regulation

 

Turkey

Wet - USD$ 335/345 per LDT

Dry - USD$ 325/335 per LDT

Container - USD$ 345/355 per LDT

Market Sentiment: Steady

3.2 Cost outside EU regulation

Cost per ton for second-hand metal from ship scraping per country as of 10.01.2022 not following EU regulation

             Bangladesh

Wet - USD$ 595/605 per LDT

Dry - USD$ 585/595 per LDT

Container - USD$ 605/615 per LDT

Market Sentiment: Declining

Pakistan

Wet - USD$ 585/595 per LDT

Dry - USD$ 575/585 per LDT

Container - USD$ 595/605 per LDT

Market Sentiment: Declining

India

Wet - USD$ 555/565 per LDT

Dry - USD$ 545/555 per LDT

Container - USD$ 565/575 per LDT

Market Sentiment: Declining

4.     Legal way to scrap vessel outside EU regulation

   The practice of beaching vessels for recycling is illegal for all European flagged ships. Owners who sell end of life ships to buyers knowing that such buyers are likely to dismantle the Ship in an unsafe and environmentally unsound manner, may, at the least, face reputational risk. At the worst, such sellers may be charged with violating waste shipment regulations. (Seatrade case)

CBM INTRO

 Intro into CBM


Obtaining insight into the common predictors of machinery failure can be an expensive endeavour. What is usually missing is the ability to make a conclusion from all the data available on board. Also managing properly the dataflows that machine failures trigger can be challenging.

By definition: 

"Condition Based Monitoring is a maintenance strategy that allows monitoring the actual condition of an asset, extracting information to understand the machines' actual wear, degradation and if a relevant change has occurred."

Condition-based monitoring is an approach to integrate machine data with existing PMS (MPMS notation). Users gain the benefit of insightful data that can integrate with their existing PMS/ERP and IMS processes to execute anything related to predictive or proactive machinery maintenance i.e. maintaining the machinery Just In Time (JIT).
Most time-based maintenance periods are arbitrary, based on initial Maker’s recommendations which in most cases go unquestioned and remain set throughout the vessel’s life.


It is impossible for Maker to undertake a full analytical maintenance justification for every piece of equipment.
 Most marine vessel failures occur due to unnecessary and excessive maintenance , incorrect installation, poor design and incorrect operation.
Condition monitoring, when combined with maintenance processes have demonstrated significant benefits throughout the maritime industry in terms of reducing maintenance activities and costs, helping to avoid unplanned stoppages and more.
 
Condition-based maintenance processes, properly applied, can help to identify and rectify problems at an early stage and can improve marine machinery reliability and reduce maintenance costs significantly.
 
This has been confirmed by the major classification agencies ( DNV GL, LR, ABS). Keeping machinery running in optimum condition reduces the likelihood that it will fail in service, leading to improved reliability and increased efficiencies.

IMS - Oil Tanker Company



Integrated Management System for Oil Tanker Company Related to Environmental Protection (IMS, ISO 14001, ISO 9001) Part I - Introduction


Nowadays, it is a requirement for all companies to have environmental protection policies; the same applies to tanker oil companies.
Tanker companies have created and incorporated in their system appropriate environmental policies;
unfortunately, most small companies treat their policies as a paper exercise and do only what is necessary to comply with rules and regulations.
On the other hand, the majority of today's modern responsible shipping company works on consolidation and integration of their system,
mostly their IMS is integrated with standards like ISO 9001: 2015 and ISO 14001:2015, to enforce their policies and increase their competitiveness in the market.
Results of that kind of integration are shown in an increase in the quality of their services and reductions in fuel consumption.

ISO 14001:2015 Environmental management systems

“part of the management system used to manage environmental aspects, fulfil compliance obligations and address risks and opportunities.”

Aim of an environmental management system

The purpose of this International Standard is to provide organisations with a framework to protect the environment
and respond to changing environmental conditions in balance with socio-economic needs.
It specifies requirements that enable an organisation to achieve the intended outcomes it sets for its environmental management system.
A systematic approach to environmental management can provide top management with information to build success over
the long term and create an option for contributing to sustainable development by:

protecting the environment by preventing or mitigating adverse environmental impacts;
mitigating the potential adverse effect of environmental conditions on the organisation;
assisting the organisation in the fulfilment of compliance obligations;
enhancing environmental performance;
controlling or influencing the way an organisation’s products and services are designed,
manufactured, distributed, consumed and disposed of by using a life cycle the perspective
that can prevent environmental impacts from being unintentionally shifted elsewhere within the life cycle;
achieving financial and operational benefits that can result from implementing environmentally sound alternatives that strengthen the organisation’s market position;
communicating environmental information to relevant interested parties;

This International Standard, like other International Standards, is not intended to increase or change an organisation’s legal requirements.

ISO 9001:2015 Quality Management systems

ISO 9001:2015 is a company-level certification based on the standard published by the International Organization for Standardization titled
"Quality management systems-Requirements".
This standard revises ISO 9001:2008 to include requirements for a new, higher-level structure as a common framework to all ISO management systems,
risk-based thinking in quality system processes, fewer prescribed requirements with less emphasis on documentation,
clear definition of the quality management system boundaries and increased leadership requirements.
Any certifications issued to ISO 9001:2008 will no longer be valid after September 2018.
ISO 9001:2015 is a non-industry-specific certification and is intended for any organisation that wants to implement and maintain a quality management system.
Certifications Are issued by third-party certifying bodies. For an organisation to maintain ISO 9001:2015 certification,
they will be subjected to annual or regularly scheduled audits to evaluate the organisation's continued compliance with the standard.

ISM Code
The purpose of the International Safety Management (ISM) Code is to provide an the international standard for the safe management and operation of ships and pollution prevention.
The Code's origins go back to the late 1980s when there was mounting concern about poor Management standards in shipping.
Investigations into accidents revealed significant errors on the part of management, and in 1987 the IMO Assembly adopted resolution A.596(15),
which called upon the Maritime Safety Committee to develop guidelines concerning shore-based management to ensure the safe operation of ro-ro passenger ferries.
The Code establishes safety-management objectives and requires a safety management system (SMS) to be established by "the Company",
which is defined as the owner or any other organisation or person, such as the manager or bareboat charterer, who has assumed responsibility for operating the ship and who,
on assuming such responsibility has agreed to take over all duties and responsibilities imposed by the Code.
The Company is then required to establish and implement a policy for achieving these objectives. This includes providing the necessary resources and shore-based support.
Every company is expected "to designate a person or persons ashore having direct access to the highest level of management" to provide a link between the company and those on board.
The procedures required by the Code should be documented and compiled in a Safety Management Manual, a copy of which should be kept on board.
Companies have recognised the need to do integration of IMS with  ISO 9001: 2015 and ISO 14001:2015 and that resulted in the creation of an INTEGRATED MANAGEMENT SYSTEM - IMS
Quality and Environment Management System and its Processes
Companies following consideration of the knowledge gained throughout the years of operation, postulates of IMS as well as the ISO 9001:2015 and 14001:2015 standards
requirements of implementing a Process approach have chosen to follow the “

"Plan-Do-Check-Act” (PDCA) management, model.

The IMS is best viewed as an organising framework, continually monitored and periodically reviewed to provide adequate direction for the company management in response to changing internal and external factors.
Everyone that is an employee of the company is expected to strive to achieve environmental improvements, as applicable.
Referring to the environmental aspect of IMS, it should be within the scope of the IMS that
the company determines the potential emergencies, including those that can have an environmental impact, i.e. any Operational Control of Aspects & Impacts. The company should maintain documented information of:

  • Risks and opportunities that need to be addressed
  • Environmental aspects and their associated impacts
  • Compliance obligations
  • Planning actions.
  • Planning is critical to the fulfilment of the environmental policy and the Establishment, implementation and maintenance of the IMS. 
The company’s planning process includes:

  • Identification of applicable legal and other requirements to which the company subscribes
  • The setting of objectives and the establishment of planning actions to achieve them.
  • The setting of internal performance criteria where appropriate, including measurable Key Performance Indicators at relevant functions and levels within the Organisation,to support the achievement of the organisational objectives.
  • Recognising the importance of planning for the fulfilment of our environmental policy and the establishment, implementation and maintenance of the IMS, the company should have  identified:
  1. All company  activities and their environmental aspects that can be controlled or influenced
  2. All the environmental impacts of each aspect.
  3. The company considers how to measure/evaluate its policy commitments, objectives and other performance criteria and establishes the Environmental Performance Indicators (EPIs). 
  4. Identifying significant environmental aspects and associated impacts is necessary to determine where control or improvement is needed and to set priorities for management action.
  5. Changes to the environment, either adverse or beneficial that result wholly or partially from environmental aspects are called environmental impacts.
  6. The relationship between environmental aspects and associated impacts is one of cause and effect.
  7. In this respect, the company should identify the environmental aspects of its activities and services, 
  8. within the defined scope of the IMS that it can control and those that it can influence and their associated impacts, considering a life cycle perspective.

When determining those aspects that have or can have significant impacts on the environment, the company should take into account:

  • Planned or new developments, new or modified activities, products and services
  • Normal/ abnormal conditions and reasonably foreseeable emergencies.
  • The company documents this information and communicates its significant environmental aspects among the various levels of employees and keeps it up to date.

The company maintains documented information of it is:

  • Environmental aspects and associated environmental impacts
  • Criteria used to determine its significant environmental aspects; the criteria are:
  • Documented legislation relevant to the aspects
  • Declared interest from the interested parties
  • Existing references in the environmental policy.
  • Significant environmental aspects
  • Scope and of its environmental policy.

The process of establishing significant environmental aspects involves the following steps:

  • Identifying, evaluating and prioritising environmental aspects.
  • Defining goals and environmental programs.

Concerning the provisions of ISO 14001:2015 and the scope of standard IMS, most shipping companies have:

  • Negligible influence on the use and end-of-life treatment of the products that are transported through its vessels;
  • Negligible influence on the design and construction of vessels before contracting for service with their owners;
  • Negligible influence on the use and end-of-life treatment of vessels after the owner’s contracting with other managers or his decision to terminate the cooperation with the company. 

The Company reviews the progress of the planning actions and evaluates the need to improve.

SPARE PARTS


APPLICATION OF A DISCRETE PROBABILITY DISTRIBUTION,  POISON DISTRIBUTION,IN CREATING CRITICAL AND OPTIMAL SPARE PARTS LIST ON OCEAN GOING VESSEL.

Note:
This article is made by modifying parts of       “INVENTORY MANAGEMENT OF CRITICAL SPARE PARTS AND ITS RELATION TO PMS”  - by Aleksandar Pudar The complete paper can be found on https://www.academia.edu/37334387/INVENTORY_MANAGEMENT_OF_CRITICAL_SPARE_PARTS_AND_ITS_RELATION_TO_PMS

The ocean-going vessel provides transportation service, and the spare parts inventory reliability is crucial.


Spare parts inventory is necessary to provide emergency services in getting the vessels back to work in the shortest time possible.
Over the years, on the older vessels, the companies accumulate an extensive inventory and the formal procedure to manage it that is due for improvement. The improvement may result in funds savings that can be used elsewhere in the company.
Existing inventory policy is being refined, and its implementation and use followed up/enforced to assist in this task.
For the calculation that resulted in the Critical or Optimal Spare Parts List for each vessel, first required variable is estimated off-hire cost ( using current rates or past 12-month average ), the failure frequency, and the machinery lifetime where it will be used.
Vessel being off-hire for any reason, whether it is for inspection, maintenance, or malfunction, costs money. The precise cost aids managers in decision making as to when to arrange vessel for dry docking, or in the case of repairs, how much to spend on getting the vessel running again.
For accurate cost projection, it is required to know what is being affected by off-hire. Vessel unemployment and income reduction may look like the most a significant part of off-hire costs, any actual cost of the off-hire, an estimate should include the value of the opportunities that were lost when the spares were not available.

To calculate the total off-hire cost, we need to sum up the following values.
  • Labour cost, direct and indirect, of the off-hire.

To find the direct labour costs, we took the length of the possible off-hire and multiplied it by the hourly costs of the vessel operators. Calculated indirect labour costs by determining how much of a share of the supervisory and support workload the vessel takes, then multiplied that by the costs of the support staff and managers.’ (Source Unknown)

  • The cost of direct value loss due to off-hire. The loss = to the worth of the service that would have been produced during the off-hire.
  • The start-up costs are related to restarting the vessel, including any additional workers needed energy surges, and inspection costs.
  • The costs are related to the actual repair, either temporarily or permanently.

Because of the cost of off-hire will usually exceed the value of the part, all items are valuable on the same level to the operations of the company, to distinguish items of interest from other items, more data needs to be collected rather than just the price of the parts.
We defined a Critical Spare Parts Calculator that took into account:
  • Off-hire cost per hour if the part is unavailable
  • Off-hire if the spare part is available in stock
  • Off-hire if the spare part is not available in stock
  • An expected remaining lifetime of the machinery
  • Estimated failure frequency
  • Inventory interest (including the cost of storeroom, depreciation)
  • Cost of the spare part
The calculator resulted in financial value:
  • Extra cost per breakdown without the spare part in stock (C)
  • ‘Probability that the spare part will be used (P)’ (Olofsson, 2018)
  • Expected downtime cost without the spare part (=C*P)
  • ‘Expected holding cost of the spare part (H)’ (Olofsson, 2018)
  • Expected obsolescence cost if the spare part never will be used (O)
  • Total spare part costs (=H+O)
  • Expected impact cost

















Table 1. Critical Spare Parts Calculator - Modified by Author - ©2009 Oskar Olofsson - www.wcm.nu 


The form is used to calculate the costs if a company buys and keeps the critical spares, or not. The calculation is based on statistical methods and is used to optimise maintenance stores. Filling in figures and estimations, and will result in a critical spare part or non-critical spare part (a buy, or not buy,) recommendation.
For the calculation: estimate downtime costs, the failure frequency, and the lifetime of the machinery where it will be used
Example (modified from- J.Fukuda Feb.2008) :
Identify a required spare parts quantity to achieve a confidence level of 90%. Following data were needed:
Units in need of spares per vessel:  4 units A = 4 EA for two vessels N = 2 vsl.
Each unit operates average 225 RH per month, M= 225 RH
The period between overhauls is 7500 RH, MTBR = 7500 RH 
The initial period of use is 24 months, T = 24 m.  Using the following formula









By using Poison Distribution [2]equation


0 spare, P = exp (-5.76) = 0.003 = 0.3% < 90%
1 spare, P = 0.003 (1+5.76) = 0.0213 = 2.13% < 90%
2 spares, P = 0.003(6.76+16.6) = 0.0736 = 7.36% < 90%
3 spares, P = 0.003 (23.36+31.85) = 0.1739 = 17.39% < 90%
4 spares, P = 0.003(55.21+45.9) = 0.3185 = 31.85% < 90%
5 spares, P = 0.003 (101.1+52.8) = 0.485 = 48.5% < 90%
6 spares, P = 0.003 (153.91+50.7) = 0.6448 = 64.48% < 90%
7 spares, P = 0.003 (204.6+41.7) = 0.7763 = 77.63% < 90%
8 spares, P = 0.003(246.3+30.1) = 0.8710= 87.10% < 90%
9 spares, P = 0.003(276.4+34.2) = 0.9316 = 93.16% > 90%

By following the above, it is determined that the recommended quantity comes to nine spare parts for 24 months lifespan of the unit in question for two ships to achieve a confidence level of 90%. Of course, to expedite the calculation, an excel spreadsheet is used.



Table 2 – “Vessel Spares Quantity (Poison Distribution) Calculator.” – Created by 3rd Officer Stefan Grozev - 2018©Reederei Nord BV - www.reederei-nord.com


The additional data needed is the lead time on the part and the cost of off-hire of the vessel, rather than just the price or the quantity of a new part. Because the new parts price is less than the cost that would incur while not having it, the cost of off-hire is used, instead, along with the lead time associated with that item.

The spares of interest are those who are not accessible to source in a short period and cause an expensive off-hire loss to the company. It takes some items weeks to receive, while others are readily available at any time. Identification of the lead time is crucial.



Snapshot 1 – Inventory - Snapshot by Author from Danaos Enterprise –Supplies Control Module 


After the downtime cost, lead time and required quantity were determined next step is to do standard RA using a matrix for each critical and optimal spare part and critical and standard equipment, and the result will be a standardised ship specific Critical and Optimal Spare Parts List. RAs has been done to ensure that there are no omissions in the use of Critical Spare Parts calculator and to identify additional risks. The goal is to minimise the losses by providing a risk assessment.
The collected spare parts data is ranked in an RA matrix allowing the technical team to visualise which items are of interest.
As it is seen, this process does not replace technical expertise and the experience or technical personnel; it aids it. 




Effective inventory management is essential and plays a pivotal role in engineering management.
Shipping companies deal with many spares, in inventory and on top we have to cope with unpredictable demand. The standard way of approach cannot be used, but instead, need to be adapted to fit the environment better to assist the company in inventory management.

[1] The form is used to calculate the costs if you buy and keep the critical spares, or not. The calculation is based on statistical methods and is used to optimize your maintenance stores. Fill in figures and estimations, and will be presented with a critical spare part or non-critical spare part (a buy, or not buy,) recommendation.
For the calculation: estimate downtime costs, the failure frequency, and the lifetime of the machinery where it will be used
[2] In probability theory and statistics, the Poisson distribution (French pronunciation: [pwasɔ̃]; in English often rendered /ˈpwɑːsɒn/), named after French mathematician Siméon Denis Poisson, is a discrete probability distribution that expresses the probability of a given number of events occurring in a fixed interval of time or space if these events occur with a known constant rate and independently of the time since the last event.[1]The Poisson distribution can also be used for the number of events in other specified intervals such as distance, area or volume.
