fied Gases in Bulk (“ EGC Code”) and the Code of the Construction and Equipment of Ships Carrying Liquefied Gases in Bulk (“ IGC Code”). In order to operate in the navigable waters of the IMO’s member states, liquefied gas carriers must have an IMO Certificate of Fitness demonstrating compliance with construction codes for liquefied gas carriers. These codes, and similar regulations in individual member states, address fire and explosion risks posed by the transport of liquefied gases. Collectively, these standards and regulations impose detailed requirements relating to the design and arrangement of cargo tanks, vents, and pipes; construction materials and compatibility; cargo pressure; and temperature control. In December 2024, the IMO Maritime Safety Committee adopted amendments to chapter 6 of the IGC Code sets out amended requirements for metallic materials used in cargo tanks that will apply to LNG carriers. These amendments are expected to enter into force in 2026. Liquefied gas carriers are also subject to international conventions that regulate pollution in international waters and a signatory’s territorial waters. Under the IMO regulations, gas carriers that comply with the IMO construction certification requirements are deemed to satisfy the requirements of Annex II of MARPOL applicable to transportation of chemicals at sea, which would otherwise apply to certain liquefied gases. With effect from January 1, 2007, the IMO revised the Annex II regulations that restrict discharges of “noxious liquid substances” during cleaning or de-ballasting operations. The revisions include significantly lower permitted discharge levels of noxious liquid substances for vessels constructed on or after the effective date, made possible by improvements in vessel technology. These discharge requirements apply to the Company’s LNG carriers. Since January 1, 2021, Annex II MARPOL has imposed stricter controls on the discharge of noxious liquid substances residues in specified areas (North West European waters, Baltic Sea area, Western European waters and the Norwegian Sea). In these areas prewash and discharge to a port reception facility are required for cargo residues and tank washings containing persistent floating products (for example, certain vegetable oils and paraffin-like cargoes).

  vii.      International Code of Safety for Ships Using Gases or Other Low-flashpoint Fuels (“ IGF Code”)  

Our dual fuel tankers meet IMO requirements of the IGF Code, which stands for the International Code of Safety for Ships Using Gases or Other Low-flashpoint Fuels. Our DF vessels have been constructed and meet, apart from SOLAS and MARPOL requirements, the IGF
