Tap into a greater depth
of marine engineering knowledge.

It’s time to think more fluidly about marine engineering. To work more collaboratively with engineering experts on solutions that work in the real world.

 

At ONA, our expertise spans the marine engineering spectrum, from technical validation and incident investigation, to marine asset management and offshore field development and installations.

This means you can select the subject-matter experts you want, gain the strategic insights you need and take uncertainty out of the marine engineering equation.

Offshore Naval Architecture

We provide specialised support services covering the unique requirements of offshore vessels, from subsea dive and construction vessels (DSVs) through to floating facilities such as FPSOs and semi-submersibles (MODUs).

Our naval architects are routinely immersed in all aspects of design, maintenance and modifications to class and regulatory requirements, with significant crossover to maritime and defence on the back of our strong hydrostatic and hydrodynamic skill sets and in-house software. ONA regularly undertake weight tracking, stability assessment and offtake related support for FPSOs, MODUs and other critical facility operations.

Crucially, our ability to unlock the complexities of dynamically positioned vessels is second to none – we offer full solutions integrating all stages of contracting commissioning, assurance, and trialing and deployment activities. We can assess all aspects of floater position keeping and mooring hook up operations.

Marine Validation and Verification

Our validation and verification services cover all vessel operations, including subsea installations, and ensure adequate engineering is completed in line with industry best practices and standards.

We have proven expertise across the board, including in conducting detailed analyses of vessel hydrodynamics, motions, multi-body interaction and lift operations.

Find out why we’re established industry leaders in providing robust practical and analytical feedback through verification scopes, and discover how we work closely and collaboratively with our clients and contractors.

Marine Transportation and Feasibility

At ONA, our consultants frequently undertake both initial and detailed feasibility studies for installation contractors, energy companies and mining interests, assessing the viability and profitability of proposed marine transportation projects.

Our studies provide clarity and understanding for our clients, qualifying implications – both in fabrication and later on-site transportation – and providing invaluable insights that underpin technical and contractual strategies, thereby ensuring successful execution.

Marine Assurance and Project Advisory

With our flexible turnkey assurance and advisory service, we’re regularly involved in marine business assurance, drawing on our engineering expertise to support clients and underwriters alike.

Our team helps formulate marine assurance plans, then implements these plans, which includes overseeing high-risk aspects of the work. It’s a collaborative, integrated approach that adds tangible value to projects, minimising costs by targeting the specific project risk requirements.

For us, this is an area of expertise that extends to undertaking technical investigations of marine-related incidents and casualties, which involves attending the scene to investigate and report on marine incidents. Often, this work is conducted for legal and insurance parties – proof of the flawless quality of our work.

Field Development and Marine Installation Studies

From subsea architecture, to flexible and steel catenary risers, through to floating and fixed structures, field development and installation is a specialty for our team.

Our consultants are intimately acquainted with the various engineering and installation limitations required for analysis that underpin rigorous installation procedures, including lift engineering and motions analysis, along with more complex scenarios like tandem tug installations.

We can also assist with engineering or consulting support at the feasibility and design-review stage, or throughout the entire design to installation process, if required. This full-cycle capability, combined with our commitment to help drive projects to fruition – on time, on budget – means we’re the perfect technical and engineering support partners, with expertise that includes conducting and managing constructability reviews and hazard identification workshops.

Marine Asset and Infrastructure Support

The maintenance of marine assets is not usually considered during the initial stages of projects, often causing the cost of maintaining these assets to remain high over the life of projects. We offer a risk-based engineering approach for marine asset management strategies, encompassing engineering, integrity and inspection activities.

With a focus on floating structures, associated mooring components and nearshore fixed structures, we pride ourselves on providing vital analytical and operational insights and experience. This includes developing benchmarked solutions and long-term maintenance strategies to suit each client’s needs up to and including the abandonment stage of an asset.

What’s more, we can also provide replacement heavy solutions to negate the need for subsea inspection campaigns, reducing ongoing operational expenditure for clients.
