Ensuring that the connectivity and reliability of countries’ national power grid extends offshore is a key part of SBSS’s portfolio. Whether that is connecting offshore energy generation facilities to the grid, or providing interconnections for archipelagic and island communities, SBSS are able to support these critical development projects with our extensive experience in engineering, planning and installing subsea power cables.

Using our advanced DP vessels, specially modified for the unique handling requirements of power cables, we ensure these high-risk projects are delivered by a capable contractor who understands there is no margin for error.

Building on our close working relationships with the region’s key power cable manufacturers, and employing strategically-located assets, we’re able to offer power cable installation, interconnections, burial and maintenance solutions, helping provide the infrastructure and resource needed to support the exponential growth in power demand in the region.
