Short OverviewChemical Tanker Notes & Operational Practice provides detailed guidance on chemical tanker operational practice, from loading through to voyage and discharge operatio ns. It includes detailed recommendations and guidance on chemical transportation by sea, as well as aspects such as cargo planning, tank cleaning, loading, conditions of carriage, ballasting and discharge.This update incorporates practical guidance from a group of experienced, currently serving chemical tanker chief officers. This edition includes over forty expanded case studies ranging from examples of load calculations to correct use of Ship/Shore Safety Checklists.The appendices provide useful reference material on chemical compounds, storage compatibilities, IMO regulations, Shipboard Marine Pollution Emergency Plans (SMPEP), the P&A Manual and cargo lists.Detailed OverviewThe second edition of Chemical Tanker Notes & Operational Practice has been extensively revised and updated to reflect current best practice in chemical tanker operations. This includes updates to procedures and recommendations for cargo carriage, which reflect the latest regulatory requirements. These primarily include updates to the International Code for the Construction and Equipment of Ships carrying Dangerous Chemicals in Bulk (IBC Code) and the MARPOL Convention.The book looks in turn at every stage of a chemical voyage, including: The importance of product identification and how this affects stowage, segregation and handling. Creating a load plan and assessment of cargo related risks, with regards to the hazards of chemicals such as noxious liquid substances. Methods of tank cleaning, tank washing mediums and testing standards for cargo tanks. Loading operations, including information on loading rates and temperatures, sampling, cargo calculations, deballasting and vapour return systems. Guidance on cargo calculations, recordkeeping and tanker related paperwork. Information on cargo tank coatings and cargo systems, including cargo pumps. Conditions of carriage and cargo care, including heated cargoes, nitrogen blanket cargoes, recirculation and inhibited cargoes. Preparations for arrival, including discharge procedures and ballasting. Prewash operations. Recent Amendments to the IBC CodeRecent amendments to the IBC Code include amendments to the contents of the model form of the Certificate of Fitness and NLS Certificates that entered into force on 1 January 2020 (Resolutions MSC.440(99) and MEPC.302(72)).However, the most significant change for chemical tankers in recent years is the revised chapters of the IBC Code and amendments to MARPOL Annex II that entered into force on 1 January 2021 (Resolution MEPC.318(74)). These amendments required the revision and replacement of the ship's existing Certificate of Fitness as well as updates to the ship's P&A Manual. Specifically, these amendments relate to Chapters 1, 15, 16 (Operational requirements), 17 (Summary of minimum requirements), 18 (List of products to which the Code does not apply), 19 and 21 of the IBC Code.The revision of Chapter 16 introduced prewash requirements, as per paragraph 13.7.1.4 of MARPOL Annex II, for persistent floating substances. This included amendments to the P&A Manual for new procedures relating to the cleaning of cargo tanks with persistent floating substances inside certain regions.Importantly Chapter 17 now indicates with "T" in column (k) whether a substance is considered a "Toxic" substance. Over 200 cargoes were added in 2020 to the cargoes having the "T" (denoting whether a substance is considered a "Toxic" substance) in IBC Code column (k). It is also a requirement of the IBC Code that when a ship carries a toxic substance, a vapor-detection instrument must be on board. Many toxic cargoes will also have more stringent requirements to stowage and segregation away from oil fuel tanks, as well as additional requirements for cargo tank relief-valve settings than non-toxic cargoes.These amendments were required to strengthen discharge requirements for cargo residues and tank washings from ships carrying NLS. The amendments therefore harmonize the list of substances and also upgrade/downgrade the ship type requirements for a number of different cargoes. Furthermore, some cargoes that were listed in Chapter 18 (list of products to which the code does not apply) have moved to Chapter 17 and will no longer be allowed to be carried on ships that do not have the required Certificate of Fitness.Finally, another recent set of amendments to the IBC Code that are due to enter into force on 1st July 2024 is those in Resolution. MSC.526(106). They relate to survivability and provide exclusions related to those openings fitted with watertight closures for application of the conditions concerning flooding or down flooding.ContentTablesCase StudiesPreface to the Second EditionPreface to the First EditionAbout the First Edition AuthorChapter 1 - Transportation of Chemicals by Sea1.1 Introduction1.2 Chemicals and Their Properties1.3 Chemicals and Their Hazards1.4 Safety Data Sheet1.5 Coatings, MARPOL and Cargo Categories1.6 Ship Types and Cargo Containment1.7 Transportation Requirements1.8 Cargo Equipment, Safety Equipment and PPE1.9 Industry OrganisationsChapter 2 - The Voyage and Cargo Planning2.1 Voyage Orders2.2 Cargo Planning2.3 Stowage, Segregation, Compatibility and Coatings2.4 Load Planning2.5 Cargo Planning and Stability Considerations2.6 Passage Planning2.7 ETA and Notice of ReadinessChapter 3 - Tank Cleaning3.1 Cleaning, Slop and Disposal Procedures3.2 Tank Cleaning Recommendations3.3 Tank Cleaning with a Cleaning Agent (additive)3.4 Tank Cleaning by Ventilation3.5 Tank Cleaning by Steaming3.6 Draining and Drying3.7 Inert Gas and Inert Gas Generator3.8 Tank Cleaning Plan and Team Meeting3.9 Tank Cleaning Equipment3.10 Preventing Unauthorised Discharge3.11 Visual Inspection of the Tank3.12 Wallwash Tests3.13 Preload Tests and ChecksChapter 4 - Loading and Departure4.1 Preparations and Precautions4.2 Tanks Inspection4.3 Pre-Cargo Meeting and Connection of Manifolds4.4 Stability During Cargo Operations4.5 Loading4.6 Ballast Operations4.7 Cargo Tank Vapour Return Systems4.8 Emergencies During Cargo Operations4.9 Loading Rate and Loading Temperature4.10 Sampling4.11 Cargo Completion and Calculation4.12 Cargo Discrepancy4.13 Short Loading4.14 Letter of Authorisation4.15 Bill of Lading4.16 Statement of Facts and Timesheets4.17 DepartureChapter 5 - Conditions of Carriage5.1 Heated and Cooled Cargoes5.2 Nitrogen Blanket Cargo5.3 Recirculation5.4 Polymerisation/Inhibited Cargo5.5 Phenol Cargo5.6 Cargo AdditivesChapter 6 - Discharging6.1 Considerations on Arrival6.2 Pumps6.3 Commencing Discharge6.4 Stripping6.5 Completing Discharge, Inspection and Blowing the Line(s)Chapter 7 - Prewash7.1 Prewash Requirements7.2 Prewash Procedures7.3 Minimum Quantity of Water Required for Prewash7.4 Persistent Floating ProductsChapter 8 - Terms and DefinitionsAppendicesAppendix 1 Compatibility ChartAppendix 2 Alphabetical Listing of CompoundsAppendix 3 Exceptions to the Compatibility ChartAppendix 4 FOSFA List of Banned Immediate Previous CargoesAppendix 5 FOSFA List of Acceptable Previous CargoesAppendix 6 International Certificate of Fitness for the Carriage of Dangerous Chemicals in BulkAppendix 7 NLS CertificateAppendix 8 Procedures and Arrangements ManualAppendix 9 Cargo Hose RecordAppendix 10 Shipboard Marine Pollution Emergency Plan (SMPEP)Appendix 11 Guidelines in Developing a SMPEPBibliographyIndex Additional InformationNumber of Pages: 332Published Date: October 2024Book Height: 210 mmBook Width: 150 mmWeight: 0 kgPublication Date: October 2024Author: Witherbys Show more
