1INTRODUCTION
1.1 Scope
This User Manual is for the nine passenger capacity FROG-9 (Model HC9-01).
Note: Throughout this manual the use of this symbol “ “ denotes safety critical
information.
1.2 Introduction
The FROG-9 Personnel Transfer Capsule (PTC) is a personnel transfer device designed to provide
increased passenger protection when carrying out the transfer of personnel between vessels and
installations.
Crane personnel transfers are carried out for a wide variety of reasons including routine, urgent
operational and emergency reasons.
The FROG-9 comprises the following two main assemblies; firstly, the stainless steel outer
framework containing polyethylene buoyancy panels, secondly, a spring-dampened seating
assembly mounted on a central column. All materials have been selected specifically to minimise
corrosion in the marine environment.
The outer framework protects passengers from impacts and contains the buoyant elements which
ensure the FROG-9 floats and is self-righting in water. At its base are keel weights which assist in
rapid self-righting.
The outer shell lands on three main peripheral feet which are supplemented by a further three
centrally mounted feet. All six feet provide shock absorption and ensure that the FROG-9 is stable on
uneven surfaces or when landing on a heaving vessel. The outer shell also has three large open
accesses that allow rapid unimpeded exit.
During transit passengers are seated and secured with full harnesses to protect them against
whiplash and falling. Seating is mounted on a sprung carriage to provide protection against heavy
landings.
The sling assembly is of a special design to prevent rotation.
Note: The regulations governing personnel transfer operations vary greatly from country to country and it is imperative
that operators of the equipment establish the relevant requirements for the area of operation.

3OPERATING PARAMETERS
3.1 Introduction
The FROG-9 has been designed to ensure passenger safety even when operating in the most
demanding conditions.
There are a large number of factors that affect the safe conduct of all marine personnel transfers.
These include: crew skill and experience, met-ocean conditions, landing area, vessel station keeping
capability and response to sea conditions, visibility, line of sight, etc. A combination of many factors
will determine the risk involved in a transfer:
Vertical impacts
Passengers are protected during heavy landings at speeds of up to 3.25 m/s (10.6 ft/s) by the
properties of the feet, frame and spring-mounted seat base. These protect passengers up to
currently recommended operating limits as detailed in Section 3.2; Table 1.
Lateral impacts
Passengers are also protected from lateral impacts by the framework and seat harnesses. Lateral
impacts are only likely to arise due to sway caused by off-lead when lifting and fast slewing. The
passengers will be protected up to the 2 m/s (6.5 ft/s) maximum expected impact speed. The central
column may deform on lateral impact and there may be damage to other components and therefore
the equipment must be inspected after any impact.
Stability
The unit has a low centre of gravity and a tripod base, providing stability on uneven surfaces or on a
pitching / rolling vessel. The polyurethane coated landing feet are also a non-skid design keeping
grip on deck surfaces. The static angle of stability has been tested to 35 degrees, for a load of 1-9
passengers.
Control of Hoist Line
The FROG-9 is designed to stay firmly on the deck of the transfer vessel whilst passengers are
entering or leaving the capsule. The Crane Operator must maintain slack in the line upon landing to
allow for the vessel movement. The recommended limits in this section are based on the use of the
standard FROG-9 sling length of 30 ft (9 m). For the use of shorter slings an additional risk
assessment combined with dry runs should be performed to establish safe operational routines and
weather conditions. (See Section 5.4 Crane Operator Guidance).
It is important that all environmental and operational factors are taken into account in the pre-
transfer risk assessment. Assessing the impact of these factors on operational risk must be done by
Competent Personnel experienced in use of the equipment and the local conditions.

FROG-9
Rev 05 Page13
3.2 Operating Parameters - Sea State
The FROG-9 has an inbuilt damping system which prevents passengers from experiencing shock
loads up to relative landing and take-off velocities of 3.25 m/s (10.5 ft/s). The maximum
recommended sea state, or significant wave height, for the operation of the FROG-9 is determined
by the maximum relative velocity between the FROG-9 (or hook) and the landing deck.
The calculation for relative velocity used here is based on the European offshore crane standard, EN
13852-1:2004. Whereby the maximum anticipated relative velocity between a load and a vessel
deck, is given by the following;
Relative velocity = Hook velocity* + √ (Vessel deck velocity 2 + Boom tip velocity 2)
* Equal to 1.67 m/s (100 m/min, 330 ft/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-9 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 risk of
heavy landings and take-off; dry runs without passengers, landing in centre of deck where less vessel movement,
transfer of fewer passengers to increase damping, hook speed indicator.
Table 1: Recommended Sea States for FROG-9
KEY

Low risk of high landing or take-off velocity and exceeding FROG-9 personnel damping.

Increasing risk of high landing or take-off velocity. Consideration of hook speed and all
other factors is recommended to ensure controlled landing and take-off. A dry run to
gauge risk (without personnel) is also recommended.

High risk of high landing or take-off velocity. Not suitable for routine operations unless
a specific hazard analysis can demonstrate otherwise.
In all cases, adequate planning and risk assessment must be performed.

Note 1: It is emphasised that users must not rely on these recommendations alone. Persons best placed to judge
the risk of specific transfers are the onsite personnel that have experience of the local conditions and
equipment to be used. All factors must be evaluated together in their pre-transfer risk assessment.
Note 2: Crews must conduct dry runs without passengers if there are any concerns about conditions to help assess
risk of transfer.

4TRANSFER PLANNING
The key to safe operations is the familiarisation and participation of all the involved crew in the
careful planning of the operation.
The Operating Parameters detailed within this document are generic, therefore safe operating
conditions must be determined by onsite supervision with due regard to site specific equipment,
vessels and conditions, taking account of any local conditions and equipment.
Safe transfers require careful planning and supervision.
The following are recommended as a means of ensuring safe transfer operations:
4.1 Risk Assessment and Method Statement
A risk assessment and method statement should be completed by the responsible authority on
board the installation and by the transfer vessel Captain prior to the first transfer operation for the
specific installation and vessel. The risk assessment should be reviewed periodically and the method
statement amended in the event of any substantive changes to equipment, procedures or any other
factors considered relevant.
4.2 Communications
Communications are an important part of controlling transfer operations. Local communication
practice will vary from work group to work group. However, dedicated 3-way radio communication
channels must, as a minimum, be provided between the Crane Operator, vessel Master, and Lift
Supervisor. A suitable radio protocol must be agreed and adhered to. Contingency communications
using a loud speaker or deck tannoy must be available.
Standard hand signals must be used by Crane Banksmen, where required, to supplement the agreed
radio communications.
4.3 Information Exchange
The following transfer vessel information must be provided to the installation:
i. General layout including the landing area position.
ii. Limiting environmental parameters for vessel station keeping.
iii. Onboard marine personnel transfer procedures.
The following installation information must be provided to the transfer vessel:
i. Crane position and hoist speed.
ii. General layout including the landing area position.
iii. Limiting environmental parameters for crane operations.
iv. Onboard marine personnel transfer procedures including responsible persons.
v. Communications channels.
vi. Any relevant information regarding local currents, field operations etc.

4.8 Emergency Transfers
If a transfer must be carried out in poor conditions in an emergency then (where time permits) a
‘trial run’ must be performed without passengers to assess operating conditions and limits.
4.9 Training
Regular transfer drills must be carried out. RML recommend weekly training drills.
4.10 Night Time Operations
With the following controls in place it may be allowable for personnel transfers using the FROG
Personnel Transfer Capsule to take place during the hours of darkness:
i. The risk assessment for the task shall be comprehensively reviewed prior to commencing
operations. The lifting plan and risk assessment shall be approved in writing by the Offshore
Installation Manager or appointed deputy.
ii. The operator should have contingency to immediately rescue the passengers from the water
e.g. Fast Rescue Craft. Without fast rescue contingency personnel transfers should not take
place.
iii. The crane boom should be fitted with adequate floodlights to illuminate the crane hook and
FROG unit. The Crane Operator must maintain a clear line of view with the FROG unit at all
times.
iv. The takeoff and landing areas should be illuminated to a level of at least 20 lux or greater.
v. The FROG unit should be fitted with a strobe light to allow clear locating by all parties.
vi. The hoisting, transit and landing paths of the FROG unit should be predefined in the lifting
plan and are adhered to.
vii. Radio contact should be maintained throughout the entire lifting operation between the
Crane Operator and the take-off and landing site.
viii. An unmanned trial run which covers, as a minimum, the take-off, transit and landing paths
of the FROG should be conducted prior to commencing personnel transfers. The Crane
Operator should confirm readiness to proceed on completion of the trial run.
ix. A non-visual based method of communicating with the lifted personnel should be in place,
e.g. radio or loudhailer, in the event of an emergency.

5.4 Crane Operator Guidance
When landing the FROG-9 on the deck of a
heaving vessel the Crane Operator must
always release and maintain line slack to
prevent any snatching. This means the FROG-
9 will be secure on the deck and will provide
occupants plenty of time to enter and exit the
FROG-9. (This landing procedure is different
to the rope basket procedure, which requires
the Crane Operator to maintain tension on
the hoist to keep the soft rope basket upright
during entry and exit).
Fig 1: Sling Diagram
For the standard 30 ft / 9 m sling provided with the FROG-9, it is generally recommended that
approximately 10 ft / 3 m of slack is paid out once the unit has landed on the vessel. However, the
required amount may vary according to sea state and vessel motion response. The Crane Operator
must pay out sufficient slack to avoid snatching, although, must avoid paying out more than is
necessary as the section of sling hanging could constitute a hazard to crews alighting or entering the
capsule.
It is also recommended that the Crane Operator slews the boom ‘down weather’ from the capsule.
This will provide more time for the Crane Operator / crews to react in the event of a failure of the
vessel’s station keeping.
5.4.1 Use of Shorter Slings
Reflex Marine Ltd recommends the use of a 30 ft / 9 m sling, however for operations where the 30 ft
sling is not suitable then a 20 ft / 6 m or 10 ft / 3 m sling can be supplied.
It must be noted that using shorter slings increases the risk of snatching. Using the 20 ft / 6 m sling,
10 ft / 3 m of slack will provide a 17.3 ft / 5.3 m allowable offset before the sling becomes taught
from the crane hook weight –this does not however account for vessel heave. For a 10 ft / 3 m sling,
8 ft / 2.4 m of slack will provide 9.8 ft / 2.7 m (allowable offset).
Using a shorter sling set also increases risks associated with the hook block being in close proximity
to the passengers alighting.
Note: The operating parameters in Section 3.2 are defined for a FROG-9 with a sling length of 30 ft / 9 m. For transfers
using a shorter sling an additional risk assessment combined with dry runs should be performed to establish safe
operation routines and weather conditions.
5.4.2 Handling Eyebolt
The FROG-9 is equipped with a handling eye in addition to the main Lift-Eye and the back-up Lift-Eye.
The handling eyebolt is an M30 stainless steel eyebolt with a Safe Working Load (SWL) of 4 Tonnes
(8818 lb).
The handling eyebolt is provided for use as a lift point when it is necessary to move the FROG-9 unit
Link to Index

User Manual
FROG-9
Rev 05 Page20
and it is not possible to use the main sling set arrangement (e.g. when a shorter sling is required due
to height restriction). In this case a shorter sling may be connected to the handling eyebolt for
handling or transportation of the FROG-9 unit and the main sling set arrangement may remain
connected.
IMPORTANT
i. The handling eyebolt must never be used as a lift point when transporting passengers.
ii. If the main sling set is to remain connected it must be coiled down inside the FROG-9 unit
and secured.
iii. The sling and attachments used for moving the FROG-9 must always be commensurate
with the load. Note: The Tare Weight of the FROG-9 is 1100 kg (2425 lb).
5.5 Use of Tag Lines
Tag lines (Hand Lines) are not supplied with the FROG. However if users wish to use tag lines for
handling the FROG the following should be considered:
Tag lines should be attached to the floor grating and 30 x 30 brace at the edge of the doorway (see
below). Reflex Marine Ltd suggest one or two 3 m lines are practicable for handling the FROG,
however length of line used is at the discretion of the deck crew.
Be aware of specific risks arising from use of tag lines:
i. Deck Crew using tag lines will be standing closer to frog during landing, which increases the
risk of impact or being caught in between.
ii. Ensure tag lines are not tied or caught on any adjacent equipment of structures.
iii. Ensure tag lines are clear of knotting and deck crew have suitable hand and eye protection.
5.6 Seating and Load Distribution
In order to perform loading efficiently and safely, the following procedures are recommended:
i. Organise passengers into groups of 9 (see note*).
ii. Confirm that passenger and luggage weight does not exceed the
SWL of the FROG-9 unit: 900 kg (or 9 x 100 kg).
iii. Split into three groups of three
Group 1: 1, 2, 3 / yellow
Group 2: 4, 5, 6 / orange
Group 3: 7, 8, 9 / red
iv. Firstly load Group 1 (1, 2 and 3) into the centre seats as
shown.
v. Next load Group 2 (4, 5 and 6) into the seats on the
right hand side of the first three.
vi. Lastly load Group 3 (7, 8 and 9) into the left hand
remaining seats.
Fig 2: Seat Loading and Tag Line Fixing Points
*Note - When the FROG-9 is used for less than 9 passengers, continue to follow the loading procedure above for as
many passengers as possible. In this way the unit will always be balanced as far as possible.
