“Everything Should Be Made as Simple as Possible, but no Simpler”

– Albert Einstein

Cube Offshore is a project management and engineering consultancy practice that believes in the practical application of technology.

We believe a successful design is dependent on a well-constructed and considered concept: those that can be manufactured, installed and operated with the highest degree of simplicity, whilst fully complying with the client brief and code requirements.

Typically, every project at Cube is unique; with projects ranging from the challenging to the simple. As creative engineers, we always seek to make the complex, simple, and the simple, efficient.

Our team represents decades of experience in the offshore and subsea industries. With industry-leading design and analysis capabilities, coupled with extensive experience of fabrication, transport, installation and operations, we collaborate with our clients to ensure successful engineering solutions.

We aim to manage interfaces and deliver and engage in long-term relationships.

Culture & Values

Client-Focus & Collaboration

Before we begin any project, we engage our clients to best understand their requirements and the stakeholders involved. Through these initial discussions, we are able to focus and prioritise workflows to deliver the most optimal outcomes.

We strive to get things right the first time by working closely and openly with our clients.


Cube Offshore’s team have decades of experience across an array of engineering disciplines. Our personnel have worked in engineering design and analysis, onshore fabrication, offshore construction, and down-hole well intervention.

We have worked with major offshore consultants, installation contractors and operators. As such, we bring a breadth of holistic industry experience to deliver considered, functional, and successful results.

Safe & Practical

We place great importance on the significant role health and safety plays within our industry. We are committed to providing safety for our staff and our clients throughout the entire life cycle of our engagement. We achieve the safest designs and installation methods through tested design principles and experienced project supervision, that are verified and certified to all industry codes. We achieve this by applying our deep understanding of fabrication, transport, installation, intervention and operations to all our engineering outcomes.


At Cube Offshore, we offer a range of engineering solutions specific to your project’s needs. Across all our work, we approach every challenge with sound engineering practices to deliver successful results.

We don’t believe one solution fits all, and are therefore not afraid to break the mould of traditional design engineering to develop something new.

How We Deliver


We operate ISO 9001 accredited Quality Management Systems.

Quality shouldn’t just be a buzz word; we believe it should be ingrained in the culture of every practice. We place great focus on attention to detail in design, manufacture, and logistics.

Project peer reviews and risk assessments are an integral part of our project process. Whether the project is designed in Perth, fabricated in Singapore, or installed in Russia, our equipment needs to fit the first time, every time.


Health, Safety and Environmental (HSE) drivers are an unquestionable priority at Cube Offshore – as the health and safety of our people always comes first.

We operate strict HSE Management Systems when visiting and working in third party facilities. If these facilities have their own HSE systems in place, we can integrate with those existing systems. Our designs and procedures ensure installation and life-cycle operations can be carried out as safely as possible.


We believe the world is a better place when we’re all working together for each other. Whether in the workplace, or out in the world, we spend our time participating in community events, team sports, and academic and industry associations.

We take great pride in donating to charitable causes, and endeavour to be a responsible corporate citizen.


How do you put a price on value when every hour billed doesn’t equate to an equal amount of value received? What is the value of a well thought out concept? To achieve real value, the key is to an engage an engineering practice with a high level of skill, knowledge, and practical experience, who has a proven history in solving challenging engineering problems and delivering successful engineering solutions.

By choosing Cube Offshore, we ensure you will receive the best outcome for your project.
