Local wave and weather conditions are critical factors when undertaking offshore operations. Precise knowledge of the sea state during such operations is an essential requirement that only becomes more critical as offshore activities move into ever-greater water depths and hostile frontier areas.
Miros’ solution is an on-board system for continuous, real-time wave and motion monitoring and recording. The dry-mounted, radar-based Miros WaveFinder comprises a vertical radar and a high-performance motion sensor (MRU). The system measures air gap, i.e. the distance from the bow down to the water surface, wave height, wave period and vessel motion, all in real time.
The "alpha factor for waves", is defined as the ratio between the operational limit and the design wave height. The objective of the standard is to ensure that marine operations are performed within defined and recognised safety levels. A vessel-mounted wave monitoring system can be used as a means to increase the "alpha factor". Type tested and approved by DNV GL, the WaveFinder is capable of providing wave data of acceptable quality in sea states up to at least 6m significant wave height. WaveFinder is Cloud-integrated, allowing seamless sharing of data between the vessel and all other stakeholders off- and onshore.
