Tether Systems



First Subsea's range of tether systems are ideally suited for deepwater environments and use in adverse climate conditions. The lean design of the tether systems ensures that minimal personnel are required for installation. 

Quick Release - Provides an inline temporary mooring solution for Mobile Offshore Drilling Units (MODU) and short term drilling vessels in severe climate conditions. This connector allows quick disconnect and reconnect of mooring lines and it can be used in extreme load conditions (loads more than 2,600T per line) and work in low temperature of up to -45°C. This can be done quickly and efficiently whilst under load to allow the vessel to manoeuvre safely away.

LankoFirst - LankoFirst is a deepwater fibre mooring connector that is smaller, lighter, easier and quicker to make-up than traditional rope connectors. LankoFirst can connect rope to rope (R2R) and rope to chain (R2C) to provide a rapid connection that can be done within 15 minutes whilst offshore. In addition only two people are needed to assemble the connector compared to at least 3 with a traditional shackle.
