3 The Bureau Veritas Group

4 Creation of Bureau Veritas 1828 : creation at Antwerp of the «Bureau de renseignements pour les assurances maritimes» by 3 marine insurers Aim : to keep underwriters informed of the premiums in use in various commercial centres and at the same time to provide«a detailed description of the good and bad qualities of vessels calling at the main ports of the Netherlands» 4

5 Bureau Veritas at a Glance A global leader in conformity assessment and certification services in the areas of quality, health and safety, environment and social responsibility (QHSE) 2011 revenue: 3.2bn More than 900 offices in 140 countries Over skilled employees Seven global businesses providing a complete set of services Inspection, testing, audit, certification, risk management, outsourcing, consulting and training services Servicing 370,000 customers across a wide range of end markets Broad Geographical Presence Asia Pacific 25% EMEA* 34% * EMEA includes: Europe excluding France Middle-East Africa Government Services & International Trade 6% Consumer Products 14% Certification 11% Revenue breakdown Seven Global Businesses Revenue breakdown The Americas 15% Marine 12% France 26% Industry 23% Construction 18% In-Service Inspection & Verification 16% 5

6 Marine international network 20 local technical centres & plan approval offices 3 Regional training Centres 1500 marine technical staff: naval architects, marine engineers and surveyors 330 marine survey stations in more than 140 countries 6

7 The BV fleet per ship type (gt) Cargo 9,6% Other 8,5% Bulker 34,4% Passenger 5,4% Container 11,9% Gas 8,4% Tanker 21,8% 7

8 Some ships within Bureau Veritas register 8

9 Role of a classification society 1. Classification of ships : a private mission of providing a level of reference standard for ship quality 2. Certification of ships : a public mission on behalf of governments and marine authorities 3. Technical assistance & consulting 9

10 Our Profession : QHSE Compliance Reference Standard Action Deliverable Assessment Full Independence from any Design / Manufacturing / Contracting / Insurance 10

11 General precautions

12 General precautions Read carefully the personal safety instructions which are available in the work instructions and the Mini Survey Handbook. The surveyor must be suitably dressed for the space to be inspected This includes shoes, gloves & hard hat. The shoes should not give rise to a spark. The surveyor should carry a suitable torch, depending on the space to be inspected, an explosion-proof torch may be required 12

13 General precautions Watch for : Deck openings open or unguarded Surveying below men working overhead or beneath loads being handled Surveys of tanks or compartments during ballasting or heavy lifting of cargoes Electric welding without proper eye protection 13

14 General precautions Watch for : Badly fixed, unsteady or unguarded scaffolding Timber of scaffolding in poor condition or overhanging Wooden hatch covers badly secured or missing Ladder rungs missing or in poor condition Decks, platforms etc., slippery or icy. 14

15 General precautions Do not conduct surveys alone or when workers have departed Internal inspections, particular care when: Inadequate lighting Slippery surfaces Open manholes in stringer plates Corroded handrails & ladders Doubt about ventilation and atmosphere 15

16 General precautions Engulfment Hazards Loose, granular material stored in holds or tanks, such as grain, sand, coal, or similar material can engulf and suffocate a worker. The loose material can crust or bridge over and break under the weight of a worker 16

17 Confined spaces

18 Confined spaces Definitions *) Enclosed space means a space which has any of the following characteristics: 1. limited openings for entry and exit; 2. inadequate ventilation; and 3. is not designed for continuous worker occupancy *) Reference: IMO MSC89/25 Appendix 23 18

19 Confined spaces 19

20 General precautions Spaces poor in oxygen include : Spaces that contain less than 20.8% Heavily corroded spaces : the corrosion process consumes O 2 Enclosed spaces partially filled with sea or fresh water experience a reduction in O 2 & the possible generation of toxic gases. Void spaces, M/E crankcases, edible oil tanks, etc. 20

21 Confined spaces Dangerous spaces Note - associated areas are considered as dangerous spaces Gas free certificate - safe for access Date / time of last verification - usually checked every 3 hours, assuming normal ventilation The certificate should be valid for the duration of the survey 21

22 Confined spaces Toxic spaces Spaces designed to contain toxic material Loading areas also included as dangerous spaces The space must not be entered if breathing apparatus is required Special equipment for testing for toxic substances - Draeger tubes Testing for oxygen 22

23 Confined spaces Boilers Enter when both manholes have been opened After ventilation & cooling If other boilers are in service check that boiler is properly isolated on steam, water and smoke sides At least two valves between the boiler under survey and the boiler under steam 23

24 General precautions The surveyor must observe the safety requirements of third parties (shipyard, terminal, owners, authority, etc.) Slightest dizziness or lack of balance is a warning & the surveyor should leave the compartment immediately Optimum oxygen level to be 20.8 to 21% Combustible gases less than 10% of the lower explosive limit. Toxins within acceptable limits Maximum hydrogen sulphide level 10ppm Maximum benzene level 10 ppm 24

25 Confined spaces O2 Enriched Normal Oxygen Deficient Atmoshere Impaired judgement & breathing Faulty Judgement, Rapid Fatigue Difficult breathing, death in minutes % OXYGEN

26 Confined spaces Flammable atmospheres Two things make an atmosphere flammable: the oxygen in the air and a flammable gas, vapor or dust in the proper mixture Different gases have different flammable ranges. If a source of ignition is introduced into a space containing a flammable atmosphere, an explosion will result An oxygen enriched atmosphere (above 22%) will cause flammable materials, such as clothing or hair, to burn violently when ignited. 26

27 Confined spaces Over 50% of workers who die in confined spaces are attempting to rescue other workers Rescuers must be trained in and follow established emergency procedures and use appropriate equipment and techniques (lifelines, respiratory protection, standby persons, etc) Steps for safe rescue should be included in all confined space entry procedures. Unplanned rescue, such as when someone instinctively rushes in to help a downed co-worker, can easily result in a double fatality, or even multiple fatalities if there are more than one "rescuer" Remember, an unplanned rescue will probably be your last 27

28 Confined spaces Prior to enter a confined space, check : When opened & how long ventilated Ventilation arrangements and means of verifying atmosphere during the survey Whether surrounding compartments are full &, if so, with what Nature of last cargo, if applicable Condition of the compartment (ballast tk. Rust) On average, there are 200 deaths per year in the Marine Industry as a result of confined space entries 28

29 Confined spaces Never trust your senses to determine if the air in a confined space is safe! You can not see or smell many toxic gases and vapours, nor can you determine the level of oxygen present. 29

30 Confined spaces Check the isolation of the compartment : IG lines blanked, valves closed & marked P/V lines blanked, valves closed & marked Cargo / ballast lines, at least 2 valves closed & marked Drainage / flushing of cargo pipe lines passing through the tank Adjacent compartments not filled with toxic material Heating coils shut off 30

32 Confined spaces Supporting documents: IMO - MSC89/25 Appendix 23 IACS - Confined space safe practise ISGOTT 5th edition Chapter 10 Enclosed space entry 32

33 Confined spaces Prior to enter a confined space, check : Safety & communication arrangements External to the compartment being surveyed Internal, during the survey Review the entry certificate / permit When was it issued and its validity (incl. times) By whom & when next verification will be made Tankers - ISGOTT regulations to be observed International safety guide for oil tankers & terminals 33

34 Check-list for entering confined spaces A check-list is available in the surveyors work instructions. Do not enter a confined space until you have considered every item of the check-list, as well as any other item of concern, and have determined the space to be safe. The check-list covers the following topics : Confirmation that you will be accompanied during entry Verification of testing equipment and qualification of testers Testing of the atmosphere for oxygen level, toxic or flammable gases Continuous monitoring of the atmosphere during survey Ventilation of the confined space Isolation of the confined space Use of adequate clothing and safety equipment Standby and rescue procedures Entry permit Remember, the final decision is yours. If you are not confident that the space is safe for entry, do not enter it. 34
