Single Point Mooring Maintenance and Operations Guide (SMOG) (3^rd Ed.)

SMOG is an industry guide with technical recommendations and guidance for the operation and maintenance of single point moorings (SPM).

The guide builds on previous recommendations and the new or significantly changed topics that are included in this edition include:
Design of SPM systems
Operation of SPM’s including:
. Operating environmental limits
. Guidance to ensure hoses are lifted safely within tanker crane capacity
. Guidance and actions regarding ship/shore cargo quantity comparison
. Qualification and training of personnel including Mooring Master skills and competence
Water flushing at SPM’s.- The use of hoses, including:
. Storage, handling and hose string assembly
. Hose time in service data from terminals
. Specific guidance following overpressure
. Hose inspection and testing
. Information regarding marine breakaway couplings
Support vessels and the use of tugs
Specific SPM Health, Safety, Security and the Environment (HSSE) guidance
