Overview
J. Ray McDermott Engineering (JRME) is one of the best-known
names in the offshore energy industry. As leaders in our field
for over50 years, we specialize in developing new, innovative,
efficient and cost-effective offshore design technologies and
project development strategies for clients worldwide.
Centered in Houston, Texas,
and supplemented by design offices in New
Orleans and Jakarta, Indonesia,
JRME specialist engineers have established a worldwide reputation
for providing top quality engineering solutions. Accredited to
ISO9001, we have the knowledge, technology, and most importantly,
the people to allow clients to realize their full field potential
with minimal risk and maximum economies of scale.
Our engineering excellence allows us to operate both as a prime
consultant or, as part of a total field development solution,
calling on the wider infrastructure of project management, fabrication
and marine services provided from within the J. Ray McDermott
group.

Engineering Technology
 Supporting
our people, state-of-the-art project controls systems interconnect
engineering, drafting, and materials groups throughout the world,
for maximum project efficiency, reducing man-hours and costs.
Using the latest in automated drafting tools and three-dimensional
Cad systems, our design teams utilize an extensive library to
facilitate the latest concepts in modular design and concept configuration.
This allows us to optimize construction time and costs and, assist
in the development of operating and maintenance strategies.
Front End Engineering & Design
J. Ray McDermott's full service engineering office in Jakarta,
Indonesia, provides Front End Engineering and Design (FEED), basic
design and engineering services for projects in the Middle East
and Far East. FEED is also provided by J. Ray McDermott's US engineering
offices in Houston and New Orleans. We aim to provide our clients
quality, cost effective engineering solutions.
All our engineering offices and fabrication facilities are electronically
linked by high speed, state-of-the-art IT systems, suitable for
all phases of engineering from FEED, through detail engineering
to commissioning.
Solutions include:
- Subsea completions (provided by Mentor)
- Compliant towers
- FPSO topsides
- Spars (provided by SparTEC)
- Mobile offshore naval base
- Fixed and floating platforms
- Tanker loading
- Berthing and storage facilities
- Mooring facilities
Detailing & Construction
Engineering
J. Ray McDermott's Dubai and Batam Island operations, locally
provide:
- Construction engineering, design detailing, drafting, fabrication
detailing, general fabrication yard support, as-built documentation
and drawing and document control.
- Hook-up, pre-commissioning and commissioning support.
When the project scope entails basic design and engineering be
supplied by our client or nominated external design house, J.
Ray McDermott can undertake detail design and drafting on site,
at our fabrication facilities. This can enhance constructability
and have added cost benefits.
Advantages
- Flexible boundaries between the engineering and the detailing
work scope.
- J. Ray McDermott can take on more or less design work as required
by the in-house or client design center, depending on the source
and content of the basic engineering design.
- The split of engineering work can be varied to suit the project
economics and capacity of the design center. The decision on
the final split of responsibilities will primarily be based
on the economics of the project, the systems available to the
design center and the available resources in the teams.
- Local detail design ensures design continuity with fabrication
activity.
- Fabrication yard resources are readily available to advise
on optimum construction solutions
- Enhanced management of engineering, fabrication and project
interfaces, as our senior operations engineer has overall control
of all fabrication related issues - from detail design and drafting,
through fabrication to pre-commissioning and commissioning.
The senior operations engineer and lead discipline engineers
work directly with our clients' yard representatives.
- Fully integrated project schedule encompassing engineering,
detail design and drafting, material procurement and construction.
Fabrication Yard Support
Local detailing offices also provide fabrication construction
engineering support for:
- Material take-off control and fabrication man-hour estimating
- Project progress
- Structural build sequences from pre assembly to load out
- Major yard lifts / structural analysis
- Load out procedures
Marine Installation Support
Our offshore construction support, engineering group, working closely with J. Ray McDermott's engineering offices in Houston and New Orleans, provides installation engineering support in the following key areas:
- Lift/Upend Analysis: structures are analyzed for the lift
condition to assess their structural integrity.
- Transportation Analysis: structures are analyzed for the transportation
forces experienced during the
journey to the offshore site, to ensure they can withstand motion
induced forces.
- Sea-fastening Design: the selected tie-down members and the barge structure are analyzed and designed to withstand the forces induced by motions during transportation.
- Installation Aids Design: lifting aids, sling protectors, tow arrangements and bumpers/guide systems are designed to ensure safe placement of the module within allowable tolerances to the designated location.
- Pile Driveability Analysis: pile driveability studies are
carried out to evaluate the general suitability of the proposed
driving systems to drive the piles to the design penetrations,
including an evaluation of the stresses induced in the pile
during installation.
Naval Architecture
- Float and Upend Analyses: a completed marine model is used for flotation and upend analyses to generate crane hook loads and generally ensure that such operations are performed safely in the subject offshore environment.
- Vessel Response Analysis: hydrodynamic models are generated to perform response studies for the design winds and waves. This study generates the vessel motion parameters for a particular tow route, as well as the boom tip acceleration for an anchored crane barge at a specific offshore location.
- Mooring Analysis: a hydrodynamic model for the moored vessel is generated to perform mooring analysis to confirm that the proposed mooring system is adequate for the design installation weather state.
- Barge Stability Analysis: the static and dynamic stability
of the cargo barge during transportation, is assessed based
on IMO or other mutually agreed statutory regulations, using
a hydrodynamic model of the barge.
- Barge Global Strength Analysis: the 'Still Water Bending Moment' is evaluated for the transportation condition, with the distributed loading components from lightship weight, transportation ballast, modules and buoyancy. The longitudinal strength of the barge is then assessed, and compared to the allowable criteria, in accordance with Classification Societies, or mutually agreed statutory regulations.
Pipeline Engineering
- Installation Analysis: this includes analysis related to the pipeline initiations, S-lay, abandonment and recovery by the lay barge equipped with necessary stingers. Installation engineering is also carried out for riser systems.
- On Bottom Stability: design of weight coating is carried out to verify on-bottom stability of the pipeline to withstand installation and operation environments.
- Wall Thickness Verification: wall thickness of the submarine pipelines is verified for installation, pressure test and in-situ conditions, in accordance with relevant working stress (WSD) or limit state (LSD) design codes.
Pre-commisioning, Hook-up & Commissioning
Support
Our engineering group provides pre-commissioning and hook-up
support including:
- Piping hydrotesting, electrical testing, instrument loop checks
etc. in accordance with project specifications
- Pre-commissioning team personnel are available to support
project commissioning requirements
