Offshore Oil & Gas and Floating LNG

ETI Offshore delivers swivels specifically designed to the clients’ needs for the transfer of fluid products, utilities, power, electrical and optical signals. To optimize space, avoid any critical interfaces, and maximize the operation uptime, ETI Offshore recommends undertaking the engineering, fabrication and assembly of the entire transfer system where all swivels are assembled in a stack. Swivel stacks are generally delivered by ETI Offshore complete with all necessary ancillaries, including driving system, bearing lubrication, monitoring and leak detection and recuperation systems.

ETI Offshore is also experienced in the refurbishment and adaption / conversion of existing swivel stacks, which would typically be required for FPSO relocations or CALM buoys overhauls.

In line with its design philosophy, ETI Offshore makes a point of providing swivels that can easily be repaired and/or replaced in situ. To that effect, spare seals are generally pre-installed on the units so that they can eventually be changed out without dismounting the swivel stack. In the unlikely event that all spare seals would have been utilized, ETI Offshore can also intervene in-situ and replace any defective seals without dismounting the swivel stack thanks to its proprietary seal bonding machine.
