1. General

1.1 Foreword

1.1.1 The purpose of this document is to provide a convenient, cohesive reference document to the various legislative and regulatory requirements and standards in Canada that apply to tugs of less than 24 metres in length.  These Guidelines have been developed not only to facilitate and simplify the tasks of the designers, builders, owners, operators, and inspectors of tugs, but ultimately to support the safety and protection of persons working aboard Canadian tugs and to protect the environment.

1.1.2 It must be noted that by virtue of the less than 24 metres in length limitation, these Guidelines specifically do not relate to any tug which is:

  • Greater than 500 gross tonnage (GT) and undertaking international voyages and hence subject to the Safety of Life at Sea (SOLAS) Convention, except when operating solely on the Great Lakes of North America and the River St Lawrence.
  • Of 24 metres in length and above and hence subject to the requirements of either the Canadian or International Load Line regulations.

1.1.3 The operators of tugs need to pay special attention to the intended operations and operating areas (including environmental factors and voyage considerations) when selecting the design most appropriate to the application, and designers and builders must specify and select materials and equipment for construction which are most appropriate to the intended service of the vessel.  Not all of these matters can be covered by regulation or by published standards, and therefore the counsel of persons well-qualified and experienced in tug design, construction and operations should be sought for each new vessel application.

1.1.4 The designer, builder, owner and operator must always refer to the most recent version of the Canada Shipping Act, 2001 (CSA 2001) and regulations made thereunder, as these Guidelines do not replace the legal requirements and may not capture recent changes made to the various regulations and/or standards. Canadian statutes and regulations prevail in the case of conflict with these Guidelines.

1.1.5 The final authority for any section of these Guidelines is the latest relevant regulation, which must be consulted prior to any undertaking.  A list of regulations and standards referred to in these Guidelines is provided in Section 1.3. This list, although comprehensive, may not capture every possible reference. The reader should therefore consult the following Transport Canada websites for a complete listing of all the Canada Shipping Act, 2001 Regulations and Transport Canada (TC) Standards:

1.1.6 These Guidelines also direct the reader to the following relevant statutes:

1.1.7 Many sections of these Guidelines also contain a heading “Additional Guidance”. The application of the information under this heading is not mandatory but is provided as it is considered to address some additional safety concerns and also represent industry best practices.

1.2 Application

1.2.1 These Guidelines address only new tugs of less than 24 metres in length, and existing tugs of less than 150 gross tonnage, unless otherwise specified. However for clarity in understanding the various regulatory boundaries there are references included herein to some specific regulations which also apply to tugs of 24 metres in length and above.

1.2.2 When applying the Regulations and Standards to existing tugs, the date of application should be verified in every Regulation. Some provisions may be applicable retroactively to all vessels, while others may only be applicable to vessels constructed after a certain date as defined in the Regulation or standard under consideration.

1.2.3 When applying the Regulations and Standards referred in these guidelines, the local Transport Canada Centre may be contacted for clarification on application or interpretation.

1.2.4 If technical advice is required owners and operators should contact a marine consultant with expertise regarding tugs and the Canadian regulatory regime.

1.4 Interpretation

1.4.1 Definitions from the Act and regulations:

  • "Act" means the Canada Shipping Act, 2001.
  • "Authorized Representative" is defined in section 14 of the Act. To summarize, it is the person who is responsible under the Canada Shipping Act, 2001 for acting with respect to all matters relating to the vessel that are not otherwise assigned by this Act to any other person. The authorized representative of a Canadian vessel is generally the owner of the vessel. Where a foreign vessel is brought into Canadian registry under a bare-boat charter, the authorized representative is the bare-boat charterer. If more than one person owns a vessel, the owners must appoint one of themselves as the authorized representative. If the owner is a corporation, the authorized representative is the corporation. In these guidelines, “owner” means “authorized representative”.
  • "Length" means for the applicability of this standard the length as defined in section 6 of the Vessel Registration and Tonnage Regulations. This length, commonly called the “Registered Length”, is shown on the Certificate of Registry. When applying various regulations, the length as defined in the regulations under consideration is applicable.
  • "MTRB" means the Marine Technical Review Board, established by section 26 of the Act.

    Note that regulations made before the coming into force of the Canada Shipping Act 2001, define the Board as the Board of Steamship Inspection, which is the previous name for the Marine Technical Review Board (MTRB). Where a regulation refers to the Board of Steamship Inspection for exemption or equivalency, it should be interpreted to mean the MTRB. When a regulation refers to the Board for inspection or approval it should be interpreted as meaning the Minister of Transport.

  • "Tow" or “Towing” means:
    • In the context of the Small Vessel Regulations: “except for the purposes of Part 10, means the action of pulling a vessel or an object astern or alongside, or pushing a vessel or an object ahead, but does not include pulling or pushing, in the course of the vessel’s normal operations, a floating object or vessel that has a significantly smaller displacement than the vessel’s displacement”.
    • In the context of the Towboat Crew Accommodations Regulations: “to pull or push any floating object”.
  • "Tug" or "Towboat" means
    • In the context of the Life Saving Equipment Regulations, Marine Personnel Regulations, Navigation Safety Regulations, Ship Station (Radio) Regulations, 1999, and Ship Station (Radio) Technical Regulations, 1999 : “a vessel used exclusively in operations associated with towing another vessel or a floating object astern or alongside or in pushing another vessel or a floating object ahead”.
    • In the context of the Small Vessel Regulations: “a vessel that is constructed or converted primarily for the purpose of towing, but does not include a vessel that is constructed or converted for the purpose of

      • (a) salvaging logs; or
      • (b) managing oil pollution booms and associated equipment”.
  • "Watertight", in relation to a structure, means the structure is capable of preventing the passage of water through it in any direction, under a head of water up to the vessel’s margin line.

1.4.2 Additional definitions used for these Guidelines:

  • "Attended Vessel" means the barge or ship to which a tug is providing towing or assistance operations.
  • "Azimuthing Propulsion" means a device capable of directing thrust through 360° for the propulsion and steering of a vessel.
  • "Escort" or "Escorting" means the use of tugs, readily available, to apply emergency steering or braking forces to an attended vessel at speeds in excess of 6 knots in confined channels or similar restricted spaces (a function distinct and separate from "Ship-Assist").
  • "Classification Society" (also sometimes referred to as "Class") means a ship Classification Society that publishes its own classification Rules (including technical requirements) in relation to the design, construction and survey of ships, and has the capacity to apply, maintain and update those Rules. For more information on major Classification Societies refer to http://www.iacs.org/ .
  • "Local Transport Canada Centre" means the Local Transport Canada Centre in the region in which the tug will operate. For contact details refer to the following website: http://www.tc.gc.ca/eng/regions.htm.
  • "Rules" means rules, codes and guides issued by a Classification Society and related to the construction, installation, and inspection of marine hulls and machinery.
  • "Ship-Assist" refers specifically to the role of tugs in the act of berthing or unberthing large vessels in port, whether directly connected to the attended vessel by a towline or not.

1.5 Additional Guidance

1.5.1 Although the existing regulations and standards apply to all tugs regardless of their size, power or voyage, the fact is that the term "tug" describes a very wide array of diverse craft which are often engaged in vastly different duties, each of which carries its own attendant degree of risk. The guidelines have attempted to identify where specific regulatory requirements are most important to any one of these particular tug services (e.g. ship-assist as opposed to towing a vessel or a floating object).

1.5.2 The current Canadian regulations applicable to tugs have often been overtaken by the technologies in the towing industry which have evolved since the early-mid 1970s, and in particular by the dominance of azimuthing propulsion as the preferred propulsion system in tugs. The reader is therefore strongly encouraged to look at sources such as Classification Society Rules in order to ensure that any new Canadian vessel reflects the lessons learned internationally regarding the safe construction and operation of such vessels.

1.5.3 There are no internationally recognized guidelines governing the relationships between the size and power of a tug and the size or type of its tow. Various documents are worthy of review however, if only to verify at least on an empirical basis that the tug-tow relationship is reasonable and appropriate. Although some of these documents relate to much larger vessels and longer (ocean) tows, they provide useful background nonetheless. References are to the latest version of these documents:

  • TP 11960 – Standards and Guidelines for the Construction, Inspection and Operation of Barges that Carry Oil in Bulk (1995), Appendix A
  • International Maritime Organization, Guidelines for Safe Ocean Towing MSC/Circ. 884
  • GL-Noble Denton: - Guidelines for the Approval of Towing Vessels 0021/ND
  • GL Noble Denton: - Guidelines for Marine Transportations, 0030/ND

2.5.2.7 In addition to the inspection required to be performed by a Marine Safety Inspector or the Classification Society Surveyor in the case of a delegated vessel (see 2.6), some of the regulations listed above require that the owner, the Master or the crew perform certain inspections and keep appropriate records of these inspections. Additionally certain systems and equipment for which there is no prescribed inspection by regulation must also be periodically verified by the owner to ensure they continue to meet the regulatory requirements.

2.5.2.8 Some regulations include provisions for certain inspections to be made by third parties. Examples are the servicing of liferafts, inspection of portable fire extinguishers and radio installations. Refer to the appropriate inspection provisions of the regulations for more information.

2.5.3 Persons authorized to carry out inspections

2.5.3.1 Transport Canada Marine Safety Inspectors are appointed under section 11 of the Canada Shipping Act 2001. The authority to carry out inspections is established by sections 11, 210 and 211 of the Act.

2.5.3.2 Under section 12 of the Act the Minister may also authorize other persons to carry out inspections. Surveyors of Recognized Organizations (see 2.6) are authorized under this section of the Act. Certain enforcement officers, such as members of the RCMP, Ontario Provincial Police (OPP) and Sureté du Québec (SQ) are also authorized under section 12 to conduct inspections, other than for construction, on vessels of less than 150 gross tonnage.

2.6 Delegated Statutory Inspection Program (DSIP)

2.6.1 In order to promote an efficient marine transportation system and encourage the harmonization of marine practices, Transport Canada has entered into formal agreements with certain Classification Societies, under the authority of the Act. These agreements cover the delegation of statutory inspection and certification functions and product approvals.

2.6.2 When a Classification Society enters into this type of agreement with Transport Canada, they are known as a Recognized Organization (RO). There are currently five Recognized Organizations in Canada:

2.6.3 For more information on the Delegated Statutory Inspection Program, refer to:

2.7 Marine Technical Review Board (MTRB)

2.7.1 The Marine Technical Review Board (MTRB) is established under section 26 of the Act to review applications for equivalencies or exemptions to requirements set out in regulations made under the Act. These applications concern individual Canadian vessels or the issuance of Canadian maritime documents to persons. The MTRB cannot make a decision that affects multiple vessels or classes of vessels.

2.7.2 To apply for an exemption or equivalency through the MTRB, the applicant should first contact the nearest Transport Canada Centre (TCC). A written application should then be submitted, and should contain the proposed alternative explaining its equivalency. A Marine Safety Inspector may contact the applicant to discuss the proposed exemption or equivalency, prior to processing the application.

2.7.3 For more information on the MTRB and its processes, refer to:

2.7.4 To contact the nearest TCC, refer to:

3. Construction Requirements

3.1 Hull Construction

3.1.1 Regulatory Requirements

3.1.1.1 The following regulations and standards apply to the hull design and construction of tugs:

  • Tugs ≤ 5 GT:
    • Small Vessel Regulations, Part 5 Section 521, Part 6 Sections 601 and 602
  • Tugs > 5 GT:
    • Hull Construction Regulations, Part VIII (specific to tugs)
  • Tugs of all sizes:
    • Hull Construction Regulations, Section 7 for Structural Strength
    • Hull Construction Regulations, Part VII Section 86 for Bulwarks and Freeing Ports
    • Marine Machinery Regulations, Schedule IX
    • Marine Personnel Regulations, Part 3, Division 3, Section 329

3.1.2 Additional Guidance

3.1.2.1 There is no TC regulation that defines in a quantifiable manner the scantlings required for a tug. The requirements of a Classification Society are recommended as general direction in this regard. For vessels undertaking Sheltered Water voyages or Near Coastal Voyages, Class 2, Limited, the ISO 12215 Small Craft – Hull Construction and Scantlings standards series may be used but the appropriate wave height design category must be considered. The side framing should be additionally strengthened as a minimum by the percentages stated in Classification Society Rules.

3.1.2.2 In general, tug owners find that the rugged service of tugs demands that the side strength of tugs should be considerably in excess of Classification Society Rules.

3.1.2.3 Note that on vessels of less than 24 metres in length, watertight doors could be of hinged or sliding type. Some owners may choose to install sliding watertight doors to allow the doors to be remotely operable from above the main deck similar to what is required in the Hull Construction Regulations section 111 for vessels of more than 24.1 metres in length.

3.2 Intact Stability

3.2.1 Regulatory Requirements

3.2.1.1 The following regulations and standards apply to the Intact Stability requirements of Canadian tugs:
 

  • Tugs ≤ 5 GT
    • Small Vessel Regulations, Part 6, Section 601
  • Tugs > 5 GT:
    • Hull Construction Regulations: Part VIII Sections 105 to 107 for inclining experiment and stability book requirements
    • Stability, Subdivision and Load Line Standards – TP 7301, STAB 1 for inclining experiment requirements, STAB 2 for stability book requirements and STAB 3 for intact stability criteria

3.2.1.2 Particular attention should be paid to the Hull Construction Regulations, Part VIII, 105-107 and the Stability, Subdivision and Load Line Standards – TP 7301, STAB1-3, pertaining to the requirements for the minimum intact stability criteria for tugs, and to the requirements for the data, methodology used and conditions to be included within the stability documentation.

3.2.2 Additional Guidance

3.2.2.1 It must be noted that by virtue of their very operation, tugs are subject to large external forces from the towline connections to their tows. The impact of these external forces is not presently considered in the referenced TC regulations. Owners are therefore strongly advised to apply the requirements for towline stability as defined by Classification Societies or other regulatory agencies such as the Australian Transport Council and its National Standard for Commercial Vessels - Part C Design And Construction - Section 6 Stability - Subsection 6A Intact Stability Requirements – Annex F (http://www.nmsc.gov.au/) to verify that a new design is safe for the intended towing task.

3.2.2.2 If a tug is to be engaged in any escorting duties, its intact stability should be thoroughly assessed for compliance with the Escort Towing Stability requirements of a major Classification Society. At present the criterion has been published by DNV, GL, and BV.

3.2.2.3 If a tug is engaged in other operations such as carrying deck cargo or lifting, the stability shall also be assessed accordingly. Appropriate operating conditions, limitations or notes to the master should be added to the stability booklet.

  • Safe Working Practices Regulations
  • Maritime Occupational Health and Safety Regulations (see 5.1.1.2)

5.1.1.2 Vessels with employees that are covered by federal health and safety legislation will fall under Part 2 of the Canada Labour Code (Section 123) and the Maritime Occupational Health and Safety Regulations. Most vessels that operate only within the limits of a province will have employees that are covered by that province’s health and safety legislation.

5.1.2 Additional Guidance

5.1.2.1 A review of the recent safety record of the towing industry indicates that the greatest risks to tug personnel are associated with movements between tug and tow, e.g. between tug and barge or between tug and log boom, and the most serious accidents occur when crew fall directly from the tow. Such occurrences are impossible to prevent by regulation, and require a safety culture aboard the tug, with an emphasis on crew awareness of the risks associated with moving onto the tow from the relative safety of the tug itself.

5.1.2.2 However there are risks inherent with every aspect of towing or ship assist. Owners must be familiar with these risks and promote safety through good design, sound construction, careful maintenance, and the implementation and enforcement of safe working practices, including in particular:

  • Operations around rotating and reciprocating machinery
  • Operations with electrical equipment
  • Operations handling fuel and oils
  • Use of major deck equipment, towlines and mooring lines
  • The appropriate matching of the tug itself to the tow and the conditions and locale in which the tow will take place
