Subjected to the most rigorous testing ever, FROG-XT4 takes crane transfer performance to a new level.

Render of FROG-XT4


Thoroughly tested, the FROG-XT4’s floating and self-righting capabilities provide extensive protection against immersion.

New hybrid, impact absorbing seats with an improved seatbelt design. Enhanced suspension system proving smoother damped motions.

Protects passengers from side impacts.

Smaller footprint for landing and storage. Optimised for transport in a standard container, reducing transport costs.

Enhanced rigging protection and easier ‘eye level’ connection for slings, improving access for pre-transfer inspections.

EVA Shock Absorbing feet provide passengers with protection against vertical impact.

The improved 3-point quick release harness is easier to put on and provides passengers with protection from whiplash.

High performance hydro-pneumatic spring damper provides enhanced vertical impact protection.

Increased capacity (now 4 persons) and average passenger weight (now 275 lbs). Increased operating envelope - now up to 4 m significant wave.


The FROG-XT4 is at the cutting edge of marine personnel transfer technology and supersedes the original FROG-3, which has a long track record of safe and effective personnel transfer.

This four-person carrier is best suited to low volume crew transfers and emergency use.

The FROG-XT4 provides extensive protection from the four major risks of personnel transfer: falling, heavy landings, collision, and immersion.


  • Thoroughly tested and verified.
  • Increases your operating envelope.
  • Small footprint for optimised landing, storage and shipping.
  • Easy to inspect and maintain.
  • Stretcher capacity to evacuate casualties.

Accessories and replacement parts

Holding a stock of replacement parts means your device is ready when you are. As a result, you’ll benefit from reduced lead times, less downtime and lower packing and freight costs.

You can also buy a range of accessories alongside your FROG-XT4 to enhance your operation. These are available at point of sale, directly from us as you need them, or from your local approved partner.

Purchase options

Manufactured in the UK, all products are stocked at our base in Aberdeen. Many are also available regionally, in a location convenient for you, through our partner network. All carriers are fully inspected, maintained and supplied with certification and supporting documents.

If you need a personnel transfer device for a short period of time, or would simply like to trial one before purchasing, we offer a rental option. This is an ideal solution for reducing downtime while your existing devices are serviced, or for providing extra transfer capacity during the construction phase of a project.

Our rental and leasing terms are very flexible, and we’ll happily work with you to create a tailored agreement that meets your needs. 

Contact our experienced sales team or one of our Approved Partners to find out more or request a quotation.
