What is SeaPlanner?

SeaPlanner is an offshore management system for the renewable energy market. It supports an industry where coordination, access, scheduling, safety, and operational visibility are vital to their  success , and where the cost of poor information can carry through an entire project/offshore operation.

Rather than build offshore teams  another disconnected tool, SeaPlanner offers Safe System of Work and Marine Management systems that support operational efficiency, stronger coordination, and reliable information across complex working environments. SeaPlanner has an established role in this space, and will continue to serve the international renewables industry as part of Ascertra.

Why is Ascertra talking about SeaPlanner now?

We are talking about SeaPlanner now because it marks the next phase in Ascertra’s growth. Since formation, our focus has been on building a global platform business that releases the power of information and helps our customers successfully and safely deliver quality projects.

That strategy continues in 2025 with the addition of SeaPlanner and Propeople to the portfolio; reflecting the progress we've already made through customer growth across our product lines, expanded office locations, and stronger reach across multiple time zones.

SeaPlanner extends our portfolio into another important operational discipline while reinforcing our long-term commitment to information certainty, safety, and dependable delivery; fitting naturally within that direction.

Was SeaPlanner acquired by Ascertra?

SeaPlanner is now part of the Ascertra portfolio, and that change comes through Ascertra assuming control of the formerly named SeaRoc Group Limited, now Ascertra-SeaRoc Limited. So  SeaPlanner is now part of Ascertra, and it moves forward with the support, scale, and resources of the broader business.

What does this mean for existing customers?

For existing SeaPlanner customers, we want to stress conintuity: current service levels will be sustained, and SeaPlanner customers will continue to be supported while benefiting from the scale of the wider Ascertra business.

Your offshore teams depend on reliable support, domain knowledge, and consistent service when coordinating people, assets, and work across demanding environments. Our commitment is to ensure that existing customers can continue to expect service continuity, ongoing support, and access to the expertise that has made SeaPlanner valuable in the first place

How will Ascertra support SeaPlanner going forward?

SeaPlanner now joins a portfolio of world-leading solutions that includes Coreworx for interface management, Mpower for project cost control, Proarc for engineering document management and control, and ProPeople HRIS software. That broader portfolio means Ascertra can offer stronger information governance across projects and operations, not just isolated systems that create more fragmentation.

Support going forward is therefore bigger than a support desk model alone—it includes combined resources, deeper bench strength, existing intellectual property, and the continuation of the SeaRoc team’s offshore management expertise within the business.

The solution remains relevant to offshore renewables, the knowledge behind it remains in place, and the wider Ascertra business provides the scale needed to support ongoing delivery.

What happens next?

For Ascertra and SeaPlanner, next comes continued delivery, deeper alignment across the portfolio, and a unified product strategy designed to create greater value for customers over time. That includes using our combined expertise and existing intellectual property to move faster where it benefits customers most.

SeaPlanner remains in market, and existing customers remain supported. The wider goal is to keep building a stronger portfolio that helps organizations deliver complex work with greater confidence, better coordination, and more reliable information.

With a unified product strategy, we will leverage our exceptional industry bench strength and existing IP to deliver greater value to our customers on a more accelerated timeline.
