OFFSHORE ENERGY
AMOG has more than 30 years of experience and a proven track record of providing leading marine and offshore engineering solutions.
Our experience covers the full range of offshore activities from pre-feasibility through Pre-FEED, FEED, detailed design, and installation management. In particular, we are able to perform design analyses using advanced numerical techniques and state of the art software, covering a broad range of issues pertinent to the design and installation of mooring and riser systems. Our expertise in VIV analysis extends to our key role in the development of maintenance of SHEAR7, the industry leading tool for the prediction of VIV effects.
AMOG’s many years of experience in the oil and gas industry, AMOG has also developed unique expertise in the area Marine Operations including metocean evaluation, vessel motion analysis and naval architecture. We also offer structural engineering for ship structures.

FEED and Design
AMOG has extensive experience AMOG is able to undertake field prospect and economic evaluation using in-house databases and facility sizing tools along with the industry leading cost estimation packages.
We can provide a wide range of services in relation to field architecture and sub-sea engineering; from high-level layouts to account for work-over activities and dropped objects, to detailed analysis of sub-sea flow line installations, to well-heads. AMOG is also able to conduct tie-in studies in which high level piping, flow-line and control systems are developed. We offer studies and reports on:
- Field layout design and drawings
- Preferred field architecture based on risk drivers
- Key risk drivers affecting field layout
- Risk reduction mitigation methods
- Stabilisation requirements of sub-sea equipment
- Foundation and Skit requirements for sub-sea equipment
- Model testing of dropped and dragged objects
- Plant Integrity Reviews (PIRs)
- Failure Investigation / Root Cause Analysis
When it comes to the design and analysis required for FEED studies, AMOG has extensive experience and can draw on a large in-house library of floaters, turrets, mooring systems, riser configurations, and metocean data to help select, benchmark and define concepts. Our specialist areas of expertise include floating production systems as well as subsea pipelines/sub-marine cables, rope technology, as well as:
- Hull Forms
- Tanker based FSO/FPSO
- Spar
- Semi-Submersible
- TLP
- Barges
- CALM
- Riser Systems
- Flexible riser systems
- Top-tensioned
- Steel catenary
- Hybrid
- Single leg offset
- Mooring systems (incl disconnectable)
- Chain
- Wire rope
- Synthetic rope
- Infield and cyclone moorings
- Turrets and Swivels
AMOG is also able to provide technical reviews of tenders for mooring equipment, riser and umbilical systems, turret arrangements, and fluid transfer systems. Our services the technical and commercial mattes pertaining to tenders, preferred suppliers based on a transparent and independent technical evaluation of supply documentation, non-compliance to tenders, and key areas of technical, commercial, schedule and contractual risk within tenders.
Operational Efficiency & Life Extension
Our carefully designed and managed Inspection and Maintenance routines are essential to the longevity of any marine infrastructure. AMOG’s design team can optimise your solutions to meet cost, fatigue, operational, and environmental constraints.
There will always be a requirement – whether imposed by regulators or as part of best practice infrastructure management – to conduct inspections on key structural and safety elements, and to perform the appropriate preventative and corrective maintenance when necessary.
This experience, over the full range of water depths, and complemented by our model testing ability, allows us to develop numerical models and interpret site data to advise on the implementation of these inspection and maintenance routines to to help assets operate more efficiently.
We are also able to develop complete documentation packages including operation and maintenance manuals.
As a more cost-effective solution, the offshore oil and gas industry is increasingly looking to extend the life of ageing production assets past the original design intent.
The challenges to increased life include; ensuring integrity given potential modifications to the floating or fixed asset, modifications to the loading design conditions over their service life, as well as the accumulative effect of fatigue loading on key structural components.
More than 30 years of engineering experience with offshore structures, leading numerous Joint Industry Projects, and expertise in corrosion and other degradation mechanisms, means that AMOG is uniquely placed to assist in the engineering and planning for refurbishments and re-certification of assets in order to extend their operating life.
AMOG has looked at the adoption of reliability methods for re-certification and life extension, particularly when dealing with less tangible residual life criteria. Now, advances in condition monitoring for moored FPSOs and fixed offshore platforms, combined with risk-based inspection criteria are assisting in extending the operation of productive assets beyond their original design life, whilst minimising ongoing costs. In particular, AMOG’s work in the area of Mooring Integrity Management (MIM) has provided key inputs into the development of API’s RP 2MIM Guidelines.
AMOG is also able to provide technical reviews of tenders for mooring equipment, riser and umbilical systems, turret arrangements, and fluid transfer systems. Our services the technical and commercial mattes pertaining to tenders, preferred suppliers based on a transparent and independent technical evaluation of supply documentation, non-compliance to tenders, and key areas of technical, commercial, schedule and contractual risk within tenders.
Decommissioning
When is comes to the decommissioning and abandonment of offshore assets, AMOG can assist with specialist abandonment studies and the validation of Safety Plans.
We are currently working on providing more detailed information on our services in this area. In the meantime, please contact us for more information.
AMOG is able to perform design analyses using advanced numerical techniques and state-of-the-art software, covering a broad range of issues pertinent to the design and installation of deepwater and other mooring systems. AMOG has extensive experience in the analysis of the dynamics of a wide range of hull forms (tanker based FSO/FPSO, Spar, Semi-Submersible,TLP, Barges, CALM) and riser (flexible riser systems)/mooring (chain, wire rope, synthetic rope) systems over the full range of water depths, complemented by our model testing capability. AMOG also specialises in disconnectable mooring systems.
AMOG is able to perform detailed dynamic analyses for multiple line systems using state-of-the-art cable dynamics packages Orcaflex, Riflex and Flexcom, complemented by mooring design tools such as ARIANE and AQWA, VIV analysis tool Shear7 and a variety of other in-house software. AMOG is able to analyse and design a range of riser systems including flexible risers, top-tensioned risers, steel catenary risers, hybrid risers and single leg offset risers. AMOG can draw upon a large in-house library of floaters, turrets, mooring systems, riser configurations and metocean data to help select, benchmark and define riser configuration concepts.
