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.

2.1.1 Sea State

The FROG-XT6 has a suspension and damping system which prevents passengers from

experiencing shock loads up to relative velocities 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.

▪XT6 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.

Parameter

Recommendation

Wind Speed

40 knot / 20 m/s (The Frog-XT is very stable in high winds.

However crane limits must be observed)

Visibility

Crane Operator should have a clear view of the pickup and

set down areas.

Vessel Motion

Pitch 10⁰

Roll 10⁰

Vessel Station-Keeping

Able to maintain position within a 5 m (16 ft) radius.

If a high risk of the vessel losing position exists, disconnect

the carrier for passenger embarkation.

Landing Area

Must be clear of obstructions, protrusions, and trip and fall

hazards.

Landing Area –Ice /

Spills

Ice and spills must be cleaned from landing area prior to

transfer.

Landing Area on Vessel

6 m x 6 m (20 ft x 20 ft) landing area is recommended,

equivalent to 2m (6.5 ft) clearance all round. Smaller landing

areas may be used provided a risk assessment of factors such

as deck hazards, weather, sea state, vessel size, station-

keeping is carried out.

Landing Area on

Installation

4 m x 4 m (13 ft x 13 ft) clear landing area is recommended

based on additional 1m entry and exit path on all sides.

Crane Requirements

Crane must be suitable for lifting personnel and properly

maintained.

Communications

Radio communication must be established between the Crane

Operator and the Vessel Deck Crew and Master.

3Using the FROG-XT

3.1 Safety Features

Protected Seating Position:

Seats are positioned behind the buoyancy panels and framework. This provides maximum

protection and minimises sense of exposure. The arrangement of the seats and 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 are 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 protective headrest designed to reduce risk of whiplash

iv. Grab handles and saddle shaped seat cushion for secure seating position

Floatation:

Buoyancy panels ensure the FROG-XT6 floats with both passengers and stretcher above the

water line. The FROG-XT6 self-rights up to 180° inverted to the vertical position and is very

stable in a range of conditions.

3.2 Passenger Instructions

i. Enter carrier and take the appropriate seat

ii. Fasten seat harness

iii. Keep hands and feet inside the carrier

iv. Hold the grab handles or the chest straps of the seat harness 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 0.2 9 | P a g e

3.3 Entry and Exit

Passenger entry and exit 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 and be

aware of any tripping hazard. When instructed, all passengers

should enter the carrier as illustrated and take their assigned

seat.

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 FROG-XT6 (note trip hazard) by the appropriate

exit.

Passengers should move clear of the carrier as directed by

the deck crew, ensuring they remain clear of the lifting

assembly.
