SEA’s pipeline system engineering professionals have played a role in all major subsea infrastructure projects in the region for the past 15 years, and bring a broad range of technical capability to pipeline projects.

We work closely with your team to deliver an integrated end-to-end pipeline solution, supported by the engineering insight needed to give the confidence required for that project phase.

Focus on Front End Value

It is well known that the total cost envelope of a project is largely defined at the concept select stage. Our end-to-end pipeline project experience and depth of technical knowledge allows us to deliver immense value to early project phases. The project environment in the early stages is often fluid, and the skilled, integrated team at SEA is well equipped to change direction swiftly – a key factor in keeping engineering costs under control.

Cost-Effective, Fit-for-Purpose

We pride ourselves on our ability to direct engineering effort to the issues that really matter on a project in order to seek out the appropriate solution. We recognise that there’s rarely only one way of solving a problem – and as an independent consultancy, we make sure that all viable options are kept open as the project evolves. This ensures the end result is robust, fit-for-purpose and supremely cost effective. For some of our clients, our approach has produced a solution that has ultimately enabled the project to proceed.

Capability Statement

Our pipeline engineering capability encompasses system engineering, architecture and hardware, shore crossing design including HDD and micro-tunnel, materials and corrosion engineering, pipeline route selection and survey support, detailed mechanical design, HT HP analysis including finite element analysis (FEA) lateral buckling, flexible flowlines and risers, subsea structures and diverless tie-ins, geotechnical assessments and foundations, and cost estimating and scheduling.


SEA offers an Inspection, Maintenance and Repair (IMR) engineering capability to support the operation of all manner of subsea assets.

Strong working knowledge of the regulatory framework relating to inspection and operation, as well as a solid understanding of industry best practises for repair and recommissioning mean that SEA is well positioned as the IMR partner of choice for local operators.

Remote Tooling

SEA also has the capability to conceptualise, specify and deliver bespoke remotely-operated subsea tooling packages that can be tailored to address the specific challenges and risks presented. When you need to react to the unexpected, or when the standard solution isn’t good enough, a bespoke remote tooling package can change the entire approach to the offshore campaign. In the right circumstances, it may avoid the mobilisation of high-specification vessels or saturation divers altogether.


SEA has a broad experience base in the design and development of subsea manifolds, pipeline structures and other elements of subsea infrastructure.

The early-stage design decisions that define how the functionality of each element integrates with the rest of the system are key drivers for the successful delivery of subsea equipment. SEA’s experience with the front end decisions of system design, coupled with hands-on experience in all phases through manufacture, commissioning, transport and installation provide significant value to clients with challenging and cost-constrained projects.

Integrated System Design Engineering

Due to the nature of remote, intervention-free operation, the functionality required of any discrete subsea component has to be carefully developed in concert with the integrated subsea system. SEA’s experience with specifying and developing both the individual elements of the system as well as the broader overall system mean that when a value or risk judgment has to be made, the decision process is informed from both perspectives.

Hands-on Engineering: Design, Manufacture, Commission, Install

While subsea XT systems are highly specialised, bespoke pieces of equipment, the manifolds, pipeline termination structures and other pieces of ancillary subsea hardware are generally simple structures assembled around proprietary items from multiple specialist vendors. Yet, even when procured at significant cost from a reputable subsea equipment vendor, completion of these structures often ends up driving the project schedule. The root cause can often be attributed to poor design decision and fabrication management that compresses the testing and commissioning schedule and puts it on the critical path. SEA offers an alternative path – design and delivery of application-specific subsea equipment, executed by engineers who understand the entire process from the first sketch on a whiteboard to installed and operating on the seabed.


SEA has built a reputation for due diligence and independent review work on the back of extensive operator-side experience in procure and construct phases of mega-projects and the company’s independence from all contractors and suppliers.

Confidentiality, independence and a depth of experience in the region – including all LNG projects in the last 15 years – provides assurance for non-operating partners, financial institutions and other stakeholders seeking independent review.

Whether the concern is cost or schedule risk and its impact on the value presented to a non-operating partner, or the technical feasibility of elements of a project, SEA is able to provide independent review in a format tailored to the client needs. This capability has also been applied to scopes requiring legally recognised expertise for review of an incident.

End-to-End System Experience

SEA, in partnership with its network of independent consultants, can provide an end-to-end review service that extends from subsurface through to the point of sale. SEA will be able to assess the intricacies of each system element between reservoir and the point of sale, as well as the risks presented by the construction and operation of the wider system. In this manner, independently generated costings for the lifecycle of the system can be compiled in a format that suits the commercial model of the client.


SEA’s focus is the practical application of technology – to reduce cost, reduce risk and add value.

SEA has developed ICE, a cloud-based intelligent computation, engineering and data platform for subsea systems. A ground-breaking alternative to the conventional discrete worksheet method of engineering, the ICE platform is built to:

  • securely organise and store subsea asset data from early stage concept phase through to operations – in one place
  • use automation algorithms to rapidly perform engineering calculations from this data at scale
  • present interactive visualisations to unlock value from engineering calculations and enable solution exploration
  • improve the speed and quality of decision making and reduce risk throughout all project phases.
SEA leverages the ICE Platform to apply modern technologies to conventional projects, including distributed cloud computing, machine learning techniques, non-linear optimisation and delivery of scalable, web-hosted calculation interfaces.


SEA has provided support to many clients engaged in procurement of materials, in an advisory capacity or acting directly on the client’s behalf.

As material costs may exceed 30% of project CAPEX, and schedule is often the key driver for procurement decisions, a tightly integrated procurement value chain is essential to manage the project’s exposure. SEA can provide the seamless link that ensures the project’s engineering requirements are robust, and are reflected in the quality of the delivered product.

Part of this capability is in SEA’s procurement experience – familiarity with likely procurement risks and constraints in the early phases of a project, and hard-won knowledge of which suppliers are able to deliver.

Package Management

SEA is proud to offer an established team that can provide package management capability to a project. Ensuring technical performance and on-schedule delivery requires continual risk management and mitigation planning to manage the risk of vendor delay or non-delivery, which have been central to SEA’s delivery of package management scopes.

Materials Engineering

SEA has delivered a strong subsea and pipeline materials engineering capability through its network of associated consultants, and has developed a considerable wealth of knowledge in-house to address the common pipeline and subsea challenges. As material cost is a significant project cost driver, SEA has delivered exceptional value in developing and reviewing material specifications to ensure the project requirements and risks are managed appropriately without unnecessary cost impact.
