For your code to work, it should look like this. (replace $post_id with your post id variable)

<?php
require_once 'wp-load.php';
require_once ABSPATH . '/wp-admin/includes/taxonomy.php';
include_once 'wp-content/plugins/acf351/acf.php';
// check if the repeater field has rows of data
if( have_rows('ddw' , $post_id) ):
    // loop through the rows of data
    while ( have_rows('ddw', $post_id) ) : the_row();

        // display a sub field value
       echo get_sub_field('op1');

    endwhile;
else :
    echo 'no rows found';
endif;
?>

You can find code samples here for all scenarios like without loop or for all posts with post ID. Try https://www.advancedcustomfields.com/resources/code-examples/
