Subsea Structures
Key Assets
The continuing trend towards subsea developments places ever greater emphasis on the need for cost effective and practical subsea structures. These structures must support and protect critical piping and equipment for the life of the field, whilst providing easy diver/ROV access for critical intervention tasks. Reliable performance of these assets is critical to the success of a development, requiring great care and attention to detail in design.
Our comprehensive design service covers conceptual, FEED, preliminary and detailed engineering of all types of subsea structure, supported by our team of experienced subsea engineers. We work closely with client, installation contractor and fabricator throughout the project to ensure suitability of final design and compress schedule.

Survey and Routing
Critical Up-front Task
Optimal route selection at the outset of an offshore pipeline project has the potential to minimise subsequent design challenges and dramatically reduce construction costs. The critical importance of routing decisions is recognised in our approach, which combines extensive experience with rapid and effective analysis tools to screen candidate routes.
Whilst these specialist skills are generally available to office-based desk studies and detailed engineering, our ability to perform rapid analysis onboard the offshore survey vessel is unique within the industry. In many cases we are able to avoid geohazards, eliminate spanning, and minimise installation difficulties even before completion of the survey.
Where routing challenges cannot be resolved offshore, we ensure the survey data acquired is adequate for rigorous assessment during FEED and detailed design.
Project Highlights
Gulf of Aqaba Crossing, 2003
The 36” pipeline passes from Taba in Egypt to Aqaba in Jordan, crossing the 860m deep Gulf of Aqaba: a depth record for a large diameter pipeline. Both sides of the gulf are extremely steep, with numerous gullies and unstable slopes, and delicate corals at the shore approaches. Any pre- or post-lay intervention would have been very costly, with no scope for trenching or rock cover. Identifying a suitable route was particularly challenging, requiring sophisticated numerical analysis to minimise span lengths and avoid landslide run-out zones. KW supported the owner, EGC, at every stage of the project, with routing specialists present on all offshore surveys. The final selected route eliminated all intervention requirements, in spite of extremely challenging seabed terrain.
Agiba Project: Gulf of Suez, 2005

Upheaval Buckling and Out-of-Straightness Analysis
KW Ltd, Fetcham Park House, Lower Road, Fetcham, Surrey KT22 9HD Tel: +44 (0)1372 371122 email: [email protected]
KW UHB/OOS Experience
Out-of-straightness (OOS) analysis is one of KW’s main
strengths that enables the company to remain at the
leading edge of upheaval buckling (UHB) analysis.
KW OOS Analysis
KW have developed an accurate and consistent OOS
analysis methodology, which is based on the use of the
SAGE Profile FE package combined with the Download
Monitoring System (DMS) to calculate the download
requirement to prevent upheaval buckling in pipelines.
The KW OOS analysis method is combined with a reliability-
based approach in order to capture the uncertainty in
design input parameters. ABAQUS non-linear FEA is used to
calibrate the OOS analysis models for HPHT and pipe-in-
pipe applications.
The DMS analysis tool, pioneered and developed by KW
staff, has been used on almost all the pipelines installed in
the North Sea since 1999. The analysis method has been
subject to DnV, Lloyds and Bureau Veritas scrutiny and
verification on several projects.
Past experience has shown that assessment of the amount
of rock cover has incorporated a large degree of
conservatism resulting in excessive cost to the installation
contractor. Thus, KW’s main OOS analysis objectives are:
• To provide an adequate level of safety in the operating
pipeline to ensure upheaval buckling will not occur
during the operating life of the pipeline.
• To minimise the volume of rock required to eliminate
upheaval buckling, commensurate with the requirements
for adequate safety.
KW Assurance
A dedicated, proactive, and responsive engineering team
with extensive experience of advanced structural mechanics
and pipeline engineering is assigned to respond to the
project’s demands.
The ability of KW to perform the OOS analysis on a very
fast track schedule can be demonstrated by reference to
our track record in this field over the past years. Rock dump
schedules can be provided as swiftly as within 24hrs, if
required, from the receipt of raw OOS survey data.

Lateral Buckling & Pipeline Walking
A New Requirement in Pipeline Engineering
The move to deep water and higher temperatures and pressures in recent years has introduced lateral buckling and walking as new requirements in the pipeline design process. Where practical and economic considerations prevent burial of pipelines, the potential to ‘snake’ and ‘walk’ is often unavoidable. Advanced design and analysis methods, often coupled with special construction measures, are then needed to ensure a safe and reliable system containing ‘engineered’ lateral buckles.
KW have been at the forefront of developments in this specialist field, with a substantial track record of lateral buckling and walking studies for leading international contractors and operators worldwide. The mitigation measures required to control walking and lateral buckling can be very costly. KW has wide experience in the design of fully integrated solutions, designed to guarantee pipeline integrity for minimum overall cost.
Specialist Services
KW can deploy a wide range of analysis tools and techniques, suitable for preliminary concept studies, tender design/validation, FEED and detailed design. Typical tasks include:
• Review of soil parameters and estimate of pipe-soil interaction forces. Specification of additional in-situ and laboratory soil tests.
• Rapid screening assessment using analytical methods (Hobbs, Taylor and Gan).
• Advanced non-linear FEA of buckle initiation and post-bukling response, including non-linear pipe-soil interaction modelling.
• Numerical analysis of interaction of trawl gear with buckled pipelines.
• Detailed FEA of strain localisation effects at field joints, forgings and weak joints.
• Analytical and FE analysis of walking (including effects of slope, thermal transients and curve pull-out).
• Global analysis of interaction of walking and lateral buckling.
• Fracture mechanics and low cycle fatigue assessments (girth weld ECA).
• Reliability analyses, to optimise buckle spacing.
Practical, optimised designs are developed, in full compliance with chosen design codes and either SAFEBUCK or DNV RP-F110 guidance.

HPHT Systems
HPHT Design Experience
The feasibility of constructing pipelines to transport high temperature and pressure contents has become central to the development of marginal fields. Pipeline systems with fluid temperatures of 160°C or more have been and are currently being designed.
At temperatures above about 120°C several factors become primary which are not significant for pipelines transporting lower temperature contents. These factors include:
• The effect of elevated temperatures on the mechanical properties of the pipeline steel, including carbon steel, corrosion resistant alloys (CRA) and CRA lined carbon steel pipe.
• Practical problems of designing pipeline systems that can be validated by current codes based on limiting stress conditions and the relevance of limit state codes to high temperature pipelines.
• The requirement to adopt a strain-based design methodology, where the adjective ‘strain-based’ is used to describe pipelines where the traditional limit on the equivalent stress in the pipeline is replaced by a limit on the strain experienced by the material.
These factors must be resolved in order to ensure that HT/HP pipelines can be operated with suitable levels of safety.
