  • Trapped Key Interlocks for Ports

    Interlocks can be used in many process or procedural systems within Ports involving the transmission of electricity, including crane movement, Ship to Shore power, and local substations or backup generators. KIRK type DM locks with chain that are attached to medium voltage connectors located in quayside vaults ensure proper procedure is followed when connecting shore to ship power. These MV connectors feed the ships with crucial electricity, enabling diesel on-ship generators to be switched off whilst in dock, also known as cold ironing. The upstream breakers feeding the vaults are equipped with KIRK® type F locks, which are keyed to correspond to the interlocks on the vault cover or connectors. This ensures power is disconnected before the connectors can be engaged or disengaged, prohibiting operations under load.

  • Environmental solutions for the utilities & electrical transmission sector

    Power companies face access challenges as they move heavy vehicles across wet, soft ground for maintenance of power lines and utilities. Access is often through environmentally-sensitive areas such as marshes and low-water crossings and undeveloped land with low soil strength. With the GEOWEB system, roads are built with 50% less cross section of aggregate, even allowing use of locally-available fill, to support heavy vehicles with minimal environmental impact. Whether for maintenance vehicle access at substations – or across land to service utility and power lines, the GEOWEB system is a surface stabilization system that is easy to deploy, easy to install, and requires virtually no maintenance.
