By May 2016, SUAB, acting as subcontractor to Vattenfall Services Nordic, completed installation of approximately 9,400 m of sea power cable across nine routes in the Trosa archipelago to supply Kråmö and nearby islands, including diver-inspected laying and weighting of the cables, construction of eight landfalls, and foundations and installation of two network stations, after which Vattenfall Services could proceed with assembly works on the islands.
Submarine power cable installation for supplying Kråmö and nearby islands in the Trosa archipelago began in March 2016, with SUAB acting as subcontractor to Vattenfall Services Nordic for Vattenfall Eldistribution. The works involved laying approximately 9.4 km of electric cable over nine stretches, constructing and installing two network stations, and preparing eight landfalls as part of a broader project to provide new electricity connections to island properties.
Onshore construction for the Kråmö Area Cables project in Trosa skärgård started in March 2016, when Vattenfall Services Nordic began works to supply islands including Kråmö with electricity. As part of this effort, subcontractor SUAB, led on site by Markus Eriksson, carried out cable laying across nine sea stretches totaling about 9,400 meters, along with onshore works such as excavation for eight cable landfalls and the foundation and installation of two network stations on the islands.
For the project to supply electricity to Kråmö and nearby islands in the Trosa archipelago, Vattenfall ordered approximately 3 km of sea-armoured (steel wire armoured) submarine cable from Nexans. The specially designed long-length submarine cable, delivered on two 14‑ton drums, was procured to enable laying of the new seabed power connections to the islands.
