Render field collection multiple times on node.tpl.php
You should read manual for field_view_field function.


Do not use inside node (or any other entity) templates; use render($content[FIELD_NAME]) instead.
Do not use to display all fields in an entity; use field_attach_prepare_view() and field_attach_view() instead.
The field_view_value() function can be used to output a single formatted field value, without label or wrapping field markup.
