Abstract
Apparatus and methods related to pipeline freespan support are described. For example, some embodiments may contain an upper structure, which contains at least four legs connected to one another by a number of bracing members, and a number of attachment points through which the upper structure can be lifted, and a lower structure, which contains at least four posts that can be connected to, and disconnected from as needed, the four legs of the upper structure, two spaced mud mats on which the posts stand, and at least two horizontal arms that can be attached to the posts, rotate about the posts, connect to and be locked with the posts on the other mud mat, and be lifted to an appropriate height to provide suitable support at the pipeline freespan location.
Claims3
An apparatus, comprising:
- a first structure, comprising:
- a first and second mud mats;

- a first sheath fitted around the first post, the first sheath being rotatable about the first post and translatable along the first post;
- a horizontal arm coupled to the first sheath so the horizontal arm is rotatable about the first post and translatable along the first post;
- a second post extending from the second mud mat;
- and
- a second sheath fitted around the second post, the second sheath comprising teeth that receives a distal end of the horizontal arm, the second sheath being translatable along the second post.
