Marine Mammal Observers (MMO)

Experienced seafarers, including former fishing vessel skippers are utilised as Marine Mammal Observers (MMOs) for a variety of offshore operations, by a range of clients including offshore oil and gas, offshore wind, and harbour construction Operators. MMOs conduct the necessary observations before and during offshore activities, and are essential during seismic surveys, diamond wire cutting operations, pipeline installation works, rock dumping, piling, and harbour construction activities to reduce the risk of injury and disturbance to marine mammals. The role of the MMO is also to advise vessel crews of the requirements for mitigation, and to liaise closely with the Client to ensure that relevant guidelines are correctly adhered to. Two MMOs are usually required to allow for maximum coverage of mammal observations in daylight hours.  Watches can sometimes be conducted from the beach during near-shore and coastal operations.
All SFFSL MMOs provided hold a Joint Nature Conservation Committee (JNCC) approved training certificate and are familiar with the various reporting requirements. Many are also training in the related Passive Acoustic Monitoring (PAM) procedures and equipment, required during hours of darkness or poor visibility.
