Historically, LNG carriers have been unable to transit the Canal, mainly due to size restrictions. Following expansion of the Canal, this Guide will benefit LNG ship operators and Masters in preparation for transit of this vital waterway via the Cocoli and Agua Clara locks.
When compiling this Guide, SIGTTO and the ACP referred to relevant ACP regulations as well as to SIGTTO guidance, industry standards and best practices. They took a proactive and consultative approach to identify issues that needed to be addressed to permit safe and efficient transit of LNG carriers through the Canal.
The Guide looks at the geography of the new locks and discusses safety, minimum equipment levels and what might be considered to be good operating practices. Some LNG carriers may need modification to comply with the ACP requirements and the Annex to the Guide summarises the structural requirements. The Guide also includes a detailed fold-out chart of the entire Canal showing depths and dimensions, navigable waters, anchorages, aids to navigation, significant features, etc (this is intended as a ready-reference and is not to be used for navigation).
It should be noted that this Guide is not a substitute for consulting the up-to-date applicable regulations and legislation (both national and international), which should always be followed in preference to this Guide.
