Introduction
This manual contains information for operating, maintaining and storing the FROG-XT4
personnel carrier. Appropriate training and pre-operational briefings should be provided for
all personnel involved in the use of this device.
Risk awareness and planning - Crane transfers (like other forms of marine transfer) are
complex operations and operators must take account of a wide range of operational
variables. By their nature they usually require the management of an interface between two
separate organisations (most frequently an installation operator and a vessel operator). It is
essential that all the key risk factors are taken into account and proper planning and
preparation is done and that all personnel involved are aware of their roles and have the
necessary competence to perform them.
Best practice references - Please refer to Offshore Personnel Transfer by Crane. This is a
separate document that contains comprehensive guidance and information on each element
of operation. It is for those researching, planning, managing or carrying out the safest
possible crane transfers.
10 Golden Rules: Personnel Transfer by Crane video also provides a useful overview of the
key risks and considerations in planning crane transfer operations.

2Operating Parameters
2.1 General
The FROG-XT range has been designed to ensure passenger safety in the most demanding
conditions.
There are a large number of factors that affect the safe conduct of marine personnel
transfers. These include crew skill and experience, met-ocean conditions, landing areas,
vessel station keeping capability and response to sea conditions, visibility and line of sight. A
combination of many factors will determine the risk involved and careful planning is a
prerequisite for safe operations (see Introduction)
2.1.1 Sea State
The FROG-XT4 has a suspension and damping system which prevents passengers from
experiencing shock loads up to relative landing of 4.5 m/s. The maximum recommended
significant wave height is based on the maximum relative velocity between the load (or
hook) and the deck.
The calculated operational sea states detailed below are based on vertical impact speeds
and bio-mechanical considerations. They reflect the ability to withstand such impacts with
minimal risk of injury to the human body. However, there are many additional factors that
may affect the safety of crane transfer operations. These include vessel station-keeping,
crew competence, wind and visibility. The operator should always refer to general guidelines
on crane transfers operations to assess overall risks.
Technical note:
The calculation for relative velocity used here is based on the European offshore crane standard,
BS EN 13852-1:2013. Whereby the maximum anticipated relative velocity between a load and a
vessel deck, is given by the following;
Relative velocity = (0.5*Hook velocity)1+ √ (Vessel deck velocity 2+ Boom tip velocity 2)
1Equal to 1.67 m/s (100 m/min) for lifts below 5 tonnes. Higher crane hook speeds may be available, and it
follows that the higher the available crane speed the higher the possibility of a heavy landing or take off.
However, with a qualified Crane Operator, it is considered unlikely that the FROG-XT will be landed at full
hook speed on a deck rising at full speed.
If there are concerns about heavy landings, operators may wish to consider the following methods to reduce
risks; dry runs without passengers, landing in centre of deck where there is less vessel movement,
transferring fewer passengers to increase damping, using a hook speed indicator.

Note:
▪Recommended Operating Limit - This is the envelope in which it would normally be considered safe subject to due consideration of other
risk factors.
▪XT4 Performance Limit - This envelope is defined by the performance limits of the capsule and the theoretical translation to significant
wave height by EN13852-1:2013. However, it is assumed that in such elevated sea states other risk factors may become
substantial. Operations should not normally be performed in this range without conducting a thorough risk assessment. Contact Reflex
Marine if you need assistance.
▪Outside operating Limit - It is not recommended - sea states are above the safe design envelope of the capsule.

2.3 Crane Transfer Planning Tool
We have developed a planning tool that can be used to determine whether the conditions
are suitable for transfers to take place.
Using the Crane Transfer Planning Tool
There are four main sections that need to be completed
i. Risk Assessment
ii. Pre-Transfer Checklist
iii. Passenger Log
iv. Post Transfer Review
The Crane Transfer Planning Tool can be found on the flash drive contained in your user
pack, or alternatively you can download a copy from our website.
It is important that the conditions are assessed prior to every set of transfers as conditions
are never exactly the same.
It is recommended that a trial run is always conducted as this provides real time feedback
on the conditions.
The operator should always refer to general guidelines on crane transfers operations to assess
overall risks.
If there is ever any concern about the conditions or the safety of the operations
transfers should be stopped.

3Using the FROG-XT
3.1 Safety Features
Protected Seating Position:
Seats are positioned directly behind the buoyancy panels providing maximum protection and
minimised sense of exposure. The arrangement of the seats and individual entry / exit
points allow rapid access and egress, allowing faster and more efficient transfers.
Fall Protection:
3-point harness system and grab handles protect from the risk of falling during transfer.
Vertical impact protection:
i. Seats mounted on a suspension system which consists of coil springs and recoil
dampers
ii. Semi-upright secure seat position, cushioned saddle seat
iii. Impact absorbing EVA foam feet
Lateral impact protection:
i. Stainless steel frame
ii. Buoyancy panels
iii. High backed headrest designed to reduce risk of whiplash
iv. Grab handles and pommel shaped seat cushion for secure seating position
Flotation:
Buoyancy panels ensure the carrier floats with both passengers and stretcher above the
water line. All XT transfer capsules are performance tested for the most extreme immersion
scenarios and self-right. All Frog-XT capsules self-rights up to 180° inverted to the vertical
position in less than 10 seconds and will provide a stable floating platform in a wide range of
conditions. Frog-XT capsules are also tested for their responses to free-fall into water.
3.2 Passenger Instructions
i. Enter carrier and take the seat to the left
ii. Fasten seat harness
iii. Keep hands and feet inside the carrier
iv. Hold the grab handles to keep body stabilised
v. Place feet onto the floor in front of the buoyancy panel
vi. Bear weight slightly onto feet in order to adopt a comfortable secure position
especially during landing and take-off

Rev 3.1 9 | P a g e
3.3 Entry and Exit
Passenger entry to and exit from should only be conducted
with the carrier in a stable position on deck as advised by the
crane operator to the deck crew member in charge of the
transfer operation.
Note: All exiting passengers must be clear of the carrier before
any new passengers attempt to board.
Each individual seat has a dedicated entry / exit point to
prevent confusion and ensure an efficient operation. All
passengers must enter and exit from the same direction.
Chevrons on the buoyancy panels are present to indicate the
direction of entry.
Entry
When advised to do so by the deck crew, passengers should
proceed as directed to one of the four entrances (note trip
hazard). When instructed, all passengers should enter the
carrier and take the seat to their left.
Passengers should ensure they are securely seated and ensure
the seat harness is securely fastened. Grab handles are
provided on the tubular upright members either side of the
buoyancy panel and passengers should grip these firmly or the
harness straps whenever seated. Passengers should never
place their hands near the load plate.
Exit
Following landing and when advised to do so by the deck crew,
passengers should unfasten the safety harness, stand and exit
the carrier (note trip hazard) by the exit to their left.
Passengers should move clear of the carrier as directed by the
deck crew, ensuring they remain clear of the lifting assembly.
Passengers should remain alert to hazard posed by the sling
(particularly in harsh weather with high deck motions). The
sling position should be managed by the deck crew as required
(see Deck Crew Instructions).
Note: It is recommended that when used to transfer only one passenger, passenger should
be seated behind buoyancy panel A.
