Care in use / Preventative maintenance
All components in the FROG-XT6-P are designed for purpose and selected to be as durable
as possible for their specific function. However, operational and storage environments can
propagate deterioration if the equipment is not kept in good condition. Factors causing of
deterioration can include:
▪
UV
▪
Sea Spray
▪
Dirt
▪
Humidity
▪
Grease and chemical
▪
Radiated heat
▪
Wind
▪
Handling and operational damage.
▪
Sea water with high chlorine content
▪
High/Excessive vibration
▪
Mould growth
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
