The  regulations vary, depending on the type of vessel and its geographical area of  operation. Rules and regulations produced by the International Maritime  Organization (IMO), flag states, agencies, regulators such as the United States  Coast Guard (USCG), and classification societies such as the American Bureau of  Shipping (ABS) can apply to insulation products. Unfamiliarity with the  intricacies of the regulations can lead to specification and installation of <br \/>\n  materials with improper certifications. An understanding of  the regulations, their areas of application, and interrelationships helps  prevent costly mistakes.<\/p>\n<p>This article discusses the passive fire protection  requirements for insulation products installed onboard marine vessels, along  with the regulatory framework and relationship between the various regulations.  Application of the regulations to various vessels is then illustrated through  examples of different vessels used in different operational activities.<\/p>\n<h5>Regulatory Environment<\/h5>\n<p>Self-propelled vessels over 500 gross tonnes involved in  international trade are subject to the IMO Safety of Life at Sea (SOLAS)  requirements.1 Similarly, Mobile Offshore Drilling Units (MODUs) involved in  international operations are subject to the IMO MODU Code requirements.2 In  addition to these international regulations, many countries&mdash;known as  flag states&mdash;have  their own requirements for vessels. For U.S.-registered vessels, the United  States, through the USCG, implements the requirements contained within the Code  of Federal Regulations. <\/p>\n<p>In addition, many individual vessels are &ldquo;classed&rdquo; with a  marine classification society, and are thus subject to additional class society  requirements. Many of the Classification Society rules are aligned with the IMO  regulations.<\/p>\n<h5>SOLAS-certificated Vessels<\/h5>\n<p>Vessels that hold a SOLAS certificate are required to comply  with the SOLAS regulations. Specifically, the passive fire protection  requirements affecting the use of insulation products are contained within  SOLAS Chapter II-2, entitled &ldquo;Construction ? Fire Protection, Fire Detection  and Fire Extinction.&rdquo; Relevant SOLAS regulations are noted below.<\/p>\n<ul>\n<li><strong>Reg. 4.4.3:<\/strong> In spaces where penetration of oil products is possible, the surface of the  insulation shall be impervious to oil or oil vapours.<\/li>\n<li><strong>Reg. 5.3.1.1:<\/strong> Insulation materials shall be non-combustible, except in cargo spaces, mail  rooms, baggage rooms and refrigerated compartments of service spaces.<\/li>\n<li><strong>Reg. 5.3.1.1:<\/strong> Vapour barriers and adhesives used in conjunction with insulation, as well as  the insulation of pipe fittings for cold service systems, need not be  non-combustible materials, but they shall be kept to the minimum quantity  practicable and their exposed surfaces shall have low flame-spread characteristics.<\/li>\n<li><strong>Reg. 6.2:<\/strong> Paints, varnishes and other finishes used on exposed interior surfaces shall  not be capable of producing excessive quantities of smoke and toxic products.<\/li>\n<\/ul>\n<p>The terms &ldquo;non-combustible,&rdquo; &ldquo;low flame-spread,&rdquo; and &ldquo;not  capable of producing excessive quantities of smoke and toxic products&rdquo; refer to  characteristics of materials determined by conducting specific fire tests.  These tests are outlined within the IMO Fire Test Procedures (FTP) Code.3<\/p>\n<p>Materials that are required to be non-combustible are to be  tested in accordance with IMO FTP Code Annex 1, Part 1. This testing, conducted  in a refractory tube furnace, uses the procedures outlined in International  Organization for Standardization (ISO) 1982:1990.4 A material is considered  non-combustible, provided that:<\/p>\n<ul>\n<li>The average mass loss does not exceed 50 percent,<\/li>\n<li>The mean duration of sustained flaming does not exceed 10 seconds,<\/li>\n<li>The average furnace thermocouple temperature rise does not exceed 30 degrees C, and<\/li>\n<li>The average surface thermocouple temperature rise does not exceed 30 C.<\/li>\n<\/ul>\n<p>Low flame-spread materials are tested in accordance with FTP  Code Annex 1, Part 5, using the test apparatus and procedures outlined in IMO  Resolution A.653(16).5 Materials that satisfy the surface flammability criteria  listed in Figure 1 meet the low flame-spread requirements.<\/p>\n<p>Materials that are required to be not capable of producing  excessive quantities of smoke and toxic products are to be tested in accordance  with IMO FTP Code Annex 1, Part 2. The optical density and concentration of  seven toxic gas species are measured following procedures outlined in ISO  5659-2:1994.6 Figure 2 lists the maximum permissible concentration of each of  the seven species.<\/p>\n<h5>U.S.-Registered Domestic Service Vessels<\/h5>\n<p>Vessels that are registered in the United States and  involved in domestic service are subject to the U.S. domestic requirements as  outlined within the U.S. Code of Federal Regulations (CFR), specifically Title  46.7 Additional guidance is provided within individual documents including  Policy File Memorandum (PFM) 1-008 and Navigational and Vessel Information  Circular (NVIC) 9-979 published by the USCG. Applicable domestic service  regulations vary, depending on the category of vessel. A selection of  insulation products and their associated USCG approval categories are listed in  Figure 3.<\/p>\n<p>Attention should be paid to the installation method for  marine insulation products, with consideration given to the expected movement  of the vessel, the normal wear expected due to the vessel&rsquo;s operation, and the  thermal effects of a fire. The specific method of attachment of the insulation  product depends upon the method of approval. Products tested in accordance with  IMO Resolution A.754 (18),10 are to be installed in the same manner as the fire  test. Products tested under 46 CFR 164.007 are to be installed in accordance  with the manufacturers&rsquo; guidelines, as approved by the USCG. Products that do  not have specific manufacturers&rsquo; installation instructions are to be installed  using welded steel pins and clips. The pins shall have a 3-millimeter diameter  at minimum and shall be spaced in a 0.3-meter grid pattern.9<\/p>\n<p>When applied to bulkheads, insulation shall be applied over  stiffeners and closely fitted around other protrusions, extending for a  distance of 300 millimeters from the bulkhead. Similarly, where an insulated  bulkhead intersects an un-insulated bulkhead, the insulation is to be  overlapped for a distance of 300 millimeters.9<\/p>\n<p>Combustible adhesives may be used to secure insulation and  vapor barriers against pipe or ductwork but shall not fail early in a fire and  shall be applied in limited quantities. Combustible adhesives shall not be in  direct contact with heat sources.9<\/p>\n<h5>Summary<\/h5>\n<p>The regulatory environment for insulation products in a  marine setting can be complicated due to different international, domestic, and  classification society requirements. An understanding of the applicable  regulations and the specific fire test requirements can ensure that the  appropriate products are specified and installed on each vessel.<\/p>\n<h5><em>References<\/em><\/h5>\n<p><em>1.
