About | Online Management for Personnel & Site Information

We provide SeaPlanner software, an integrated SaaS solution built specifically to help the offshore wind industry drive safety, efficiency, and compliance across projects. SeaPlanner combines the functionalities of a robust Marine Management System (MMS) with the detailed procedures of a Safe System of Work (SSoW) to provide a seamless, all-in-one platform for managing offshore projects.

We were founded in 2002 to develop solutions to support the build, management, and operation of offshore renewable energy projects. We were one of the first software-based businesses in the market, and our solutions benefit from years of learning and working closely with customers to refine our solutions based on real-world experience. Since then we have grown in scope and are trusted by some of the biggest names in offshore and onshore construction and infrastructure.

Today, we operate around the world as part of the Ascertra organization and are continually evolving our industry-proven SeaPlanner Offshore Management System by listening to customers, collaborating with partners, and anticipating future demand. Throughout our journey, we have been recognised for our dedication to customer service, integrity, and execution.
