SFF Services provide qualified offshore and onshore personnel to meet client requirements. Experienced seafarers, including former fishing vessel skippers, have been utilised as Marine Mammal Observers (MMOs) for a variety of offshore operations, conducting the necessary observations prior to and during offshore activities. Most commonly required during seismic surveys to reduce the risk of injury and disturbance to marine mammals, MMOs have also been supplied during other offshore campaigns such as pipeline installation, rock dumping, piling, and renewable energy operations.


Watches can also be conducted from the beach during near-shore and coastal operations. 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 the relevant guidelines are correctly adhered to. Two MMOs may be required at certain times of the year in sensitive areas, allowing for maximum coverage of mammal observations in daylight hours.


All 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.
