2020 HIGHLIGHTS The ‘Go-Barry’ – a Self-Moving Traffic Barrier

in Panama consisting of a collection of steel dodecahedrons: Endless Reefs. Artificial reefs have the potential to enhance marine diversity around our coastal infrastructure projects, as well as become an integral part of our coastal protection projects. Endless Reefs employs Mineral Accretion Technology that uses low-voltage, electrical currents underwater to accelerate the process of calcification, promoting the growth of marine life. Vacuum-Supported Soil Construction Vacuum-Supported Soil Construction (VSCC) is a method of creating reinforced soil constructions. Conventionally, during construction projects, temporary walls are erected to hold geogrids and granular material in place until construction is completed and the wall can support itself. VSSC eliminates the need for these temporary walls, saving time, material and floor space. VSCC is expected to see applications within Boskalis Nederland. PortXL Boskalis partners with PortXL, the world’s first port and maritime accelerator program, scouting and selecting innovative new companies that can serve the needs of the global maritime industry. PortXL is a dynamic program, responding quickly to industry needs. In 2020, as a result of this partnership, we

Delivering substantial safety advantages for road workers, as well as improved traffic flow and time savings, the Go-Barry integrates several track-propelled undercarriages into an existing traffic barrier. Designed for roadwork situations, Go-Barry utilizes remote contact between a road worker and the barrier, enabling the barrier to be moved without human intervention; it has attracted great interest from our clients, was tested in a Proof of Concept at the end of 2020 and a prototype will be tested in 2021. Remotely Operated Cutting Tool Traditionally, offshore platforms require pre-fabricated cutting platforms to be installed on each leg of the platform when the platform is dismantled at the end of a project – an expensive and potentially hazardous exercise. The remotely operated cutting tool, due to be employed during upcoming decommissioning operations, not only represents significant cost savings, but makes a substantial contribution to the safety of our, and our clients’, employees. Endless Reefs In an extension of our extensive research into artificial reefs over the last years, in 2020 we started a pilot with a modular solution
