Protecting steel ropes

More tidal power on- stream

Lubricant specialist Metalube has supplied its biodegradable lubricants for use on the lifting cranes employed to build a multi- billion dollar, 55 km bridge linking Hong Kong to Macau. As one of the world’s longest sea bridges there was a need to ensure that products used over open ocean were biodegradable, and harmless to the environment. Metalube’s Ropetek WRD 40-1 offers effective lubrication whilst remaining environmentally friendly, and was used on ropes throughout the bridge’s construction. Ropetek WRD 40-1 provides effective lubrication and corrosion protection to the steel ropes of the floating cranes, offering greater rope longevity whilst also protecting the sea water environment. The product provides high resistance to moisture and oxidation, and protects against corrosion- induced failure. It also has high-load carrying solids that minimize friction and wear between wires and strands.

Swedish marine energy developer Minesto has entered intoacollaborationagreement with SEV, themain power utility on the Faroe Islands, for the installation of two DG100 100 kW tidal energy devices. The collaboration will cover installation, commissioning and operation of two grid- connected DG100 units, part of Minesto’s Deep Green subsea kite technology. According to Minesto, installation of the first unit is planned for late 2019 or early 2020, with the following unit to be installed in 2020. SEV will provide the required infrastructure, such as grid connection, and resources for consenting processes. Site development is in progress with an identified site in Vestmannasund, a strait in the north-west part of Faroe Islands. The collaboration is the first phase of a long- term ambition to add further tidal energy capacity to the Faroe Island’s energy mix. Faroe Islands has set a goal of meeting its entire electricity needs from renewable energy sources by 2030, including transport and heating.
