INSTALLATION OF SUBSEA EQUIPMENT 
19.1 
SCOPE 
19.1.1 
This section of the guidelines are specifically related to the installation of the following items subsea: 

Manifolds, Protection Structures, Templates and Production Equipment, including: 
o 
Xmas trees 
o 
Choke systems 
o 
BOPs 
o 
Subsea production equipment (multiphase pumps, separators, compressors, etc.) 
o 
Control modules 
o 
Guide posts 
o 
Intervention tooling. 
o 
Ancillary equipment e.g. concrete mattresses, PLETs, PLEMs (when not installed as part 
of pipelay operations). 

Anchor piles (see Section 19.8 for suction and Section 19.9 for driven piles) 

Jumpers and tie-in spools (see Section 19.10) 

Rigid Pipe Risers (see Section 19.11) 

Storage Tanks (see Section 19.12) 

Tidal & wave generators 
19.1.2 
The installation of: 

Pipelines, flowlines and risers from a laying vessel, and 

PLETs & PLEMs when being installed as part of the pipeline/ pipe string
is covered by 0029/ND, Guidelines for Submarine Pipeline Installation, Ref. [4]. However, in some 
instances, the installation of a PLET at the initiation or termination of the pipelay will be covered by 
both guidelines; for example a PLET connected to line pipe but lowered by crane and winch with a 
damping system using buoys.
