Components that may specifically be affected by one or a combination of these factors are:
Wire rope lifting assembly.
The wire rope lifting assembly ‘sling’ is the most safety
critical and vulnerable component in the whole FROG assembly. It is vulnerable to
damage from handling and operations and susceptible to corrosion from sea spray and
moisture build-up. The lifting assembly should be inspected by a competent person prior
to every use. To prevent damage or corrosion the following is advised:
▪
When not in use the lifting assembly is coiled and stored on the floor grating of the
FROG;
▪
When not in use for long periods the lifting assembly should be removed from the
FROG, the cover removed, and stored in a secure, dry place;
▪
If the FROG is kept on an open vessel deck and subject to sea spray, where possible,
keep equipment covered or keep in a deck area sheltered from sea spray. Note: for
high speed craft wind effects may cause covers to fray.
Seat damping springs.
Sea spray, particularly on equipment that is kept on vessel open
deck, can propagate corrosion and cracking in the springs therefore the following is
advised in such situations:
▪
Where possible equipment is covered or kept in a deck area sheltered from sea
spray. Note: for high speed craft wind effects may cause covers to fray;
▪
Springs are washed down with fresh water at regular intervals, i.e. after each
voyage;
▪
Springs are inspected regularly. Specific inspection recommendations for springs can
be found in the inspection checklist.
▪
Protection grease may be used to coat springs to reduce onset of corrosion.
Seat harnesses.
A combination of the factors listed above can cause deterioration of
the seat harnesses. These should be cleaned regularly with fresh water and mild
detergent. When stored the harnesses should be fastened so that they do not flap in the
wind. For longer durations of storage, it is recommended that the equipment is covered,
or the harnesses are secured with cable ties. Signs of damage will be fraying and brittle
webbing weave.
Landing feet.
Heat radiated from deck can cause accelerated compression in the shock
mitigation foam landing feet. For periods where the FROG-XT4 is stored for long periods
it is recommended that the unit is chocked (raised) from the deck.
Transport and vibration.
For longer periods of storage in environment with vibration,
and when equipment is transported, the threaded fixings on the unit should be inspected
to ensure no slackening has occurred.
General.
The Frog-XT4 should be washed with fresh water regularly to prevent build-up
of salt, dirt, and any contaminants.
