In modern offshore cable operations

the diversity

urgency

and location uncertainty of communications have become increasingly prominent

and traditional communication methods can not meet these requirement anymore. The advantages of using dual-mode satellites and wireless mesh ad hoc networks in dynamic marine environments are analyzed in this article.Based on the analysis of the wireless communication requirements for submarine cable operations

a space-airground-ocean integrated communication architecture is proposed.Through the integration of dual-mode satellite communication and wireless mesh ad hoc networks

the resources of space-based

air-based

shore-based

and sea-based communication platforms are coordinated across multiple domains. By optimizing the routing metric in the hybrid wireless Mesh protocol(HWMP) and incorporating multipath routing algorithms

efficient cable operation data transmission can be achieved. This scheme not only provides comprehensive wireless network coverage for submarine cable work sites

but also provides robust communication support for offshore personnel

and establishes efficient and reliable wireless communication links between work vessels and land command centers

thereby effectively improving the efficiency and safety of offshore operations.
