Our focus for successful installation campaigns is to ensure precisely engineered offshore operations, not only to deliver certainty the first time, but to optimize cost and mitigate risks involved while in the field, especially critical for deepwater developments and harsh environments hundreds of miles from shore.
Critical Analysis
|
|
We are experts at carrying out the modeling and analysis required for any type of installation methodology, for any structure, anywhere in the world – for fast-track or regular project schedules. McDermott engineers undertake detailed reviews and interpretation of the critical aspects of installation campaigns for fixed, floating and subsea facilities to examine and simulate transportation methods, site conditions from the most likely to the most extreme, as well as lift, launch or lay methodology and available assets. We work closely with engineers across our marine and fabrication groups globally, as well as other specialist contractors, to enable fully engineered installation solutions that are cost efficient, optimized and above all, safe to ensure operations go smoothly out in the field.

Services Performed
|
|
During our decades offshore we have developed innovative solutions for the safe installation of:
- Fixed facilities (jackets, topsides, including launch, upending, lift and float-over installation)
- Floating facilities for Spar, TLP, Semisubmersible, and FPSO (hulls, topsides, mooring systems, including hull tow / upending, topside lift / float-over installation)
- Subsea facilities (PLETS, PLEMS, jumpers, manifolds, spools and flying leads)
- Transportation and installation, including sea fastenings and tow arrangements
- Floating vessel motion analysis and testing
- Vessel mooring and station keeping
- Pipeline route survey, rock dumping, trenching and burial
- Rigid pipelay using S-lay, J-lay, Reel-Lay, tow and beach pull
- Flexible product / pipelay, cable lay and umbilicals using horizontal and vertical Reel-Lay / Flex-Lay
- Mooring system analysis and deployment
- Riser installation and J-tube pull-in
- Hook-up
