We serve physics

Across the offshore arena we rely on a scientific approach and experience based pragmatism to ensure optimal performance in our clients projects.

Our services

Installation analysis

Throughout our 250+ projects involving T&I activities we have build a wide experience base including nearly all conceivable installation activities.
 
Some projects require straightforward Hs and Tp limits where other projects can benefit significantly from a more sophisticated approach. Saving days or weeks of vessel utilization while maintaining safety margins is what T&I analysis should focus on.
Mocean has developed 3 main analysis types for T&I:
 
1. Basic analysis resulting in, for example, Hs and Tp limits for a set of operational phases. This serves basic marine engineering projects where clients have excessive track record and are not keen to optimize, rather to obtain the required approvals to comply with regulations swiftly and effortlessly.
 
2. Snap shot time domain analysis of selected ‘frozen’ moments during a T&I operation. We include all relevant physics from diffraction, hydraulics of actuators, detailed mechanical systems, CFD analysis and a myriad of other physic’s engines.
 
3. Especially for projects with high weather risk and repetitive operations we adopt our ‘mocean’ method. It involves statistically correct (as opposed to the approaches suggested in classification rules) transient time domain analysis combined with seasonal wave occurrence statistics and project risk assessment. This method allows our client to have actual insight in how risk and reward are balanced and optimized.
 
We aim to deliver a theoretically detailed report alongside an easy-use results-app that allows our client to have very clear and concise information at hand at all times.

Moorings and floating systems analysis

Our team has contributed to over 80 mooring projects since 2013.
 
Mooring analysis requires not only a proper understanding of the physics involved but also of the statistical implications of how load cases are selected, analyzed and post-processed.
Mooring design goes beyond ‘top of mind’ CALM chain selection and anchor spread. It often closely interferes with riser design and other restrictive aspects. Where deep-water mooring offers it’s challenges, it is the shallow water mooring projects that mostly result in the need for innovative solutions. This is where we strive to aid our clients needs. Examples we have extensive experience with include:
 
1. Soft yoke mooring system design for shallow large vessel conditrions
 
2. Side-by-Side mooring solution at open sea, a highly dynamic and challenging operation
 
3. Deepwater floating wind mooring design, where efficient use of materials and in-depth understanding of WTG performance are of key importance. Also floater stability and towing resistance impact the overall performance.

Surf, cable and pipeline analysis

Often the flexibles are the Achilles heel of offshore installations, be it windfarms or O&G installations. The design of cable, riser or other flexibles should therefore be done in parallel with mooring analysis to determine surface excitation and seabed currents and scour effects to include all possible configurations during the lifetime. 
Common cable lay analysis include regular lay, 1st end & 2nd end pull-ins and a range of associated special operations.
 
Fatigue analysis of flexibles requires proper benchmarks as supplier specifications of mechanical performance is often unclear of ill-defined. Also the changing local conditions due to scour should be accounted for. The impact of the various analysis methods is often underestimated and should be carefully considered. Qualitative engineering advice should aid decision making in design and potential mitigating action procedures.
 
A wide range Riser and sub-sea jumper installation projects have taught us the importance of producing clear input for procedures while optimizing for workability
 
More exotic design activities such as for Deep Sea Mining in 5000m deep waters requires a combination of being aware of all physical aspects while also being able to produce a lean design that will obtain approval from all relevant stakeholders. This requires better and more elaborate reporting as parties have little to no reference to previous projects. This is where we create confidence throughout all stakeholders through our scientific yet pragmatic approach.

CFD for Maritime Applications

For complex fluid dynamics, we can use CFD to fulfill the needs of our clients. Depending on the project scale and wishes, we can conduct full CFD studies or simply define a subscope to support in areas where typical approaches become too simplistic and invalid.

We realize that CFD is not only about showing diagrams with fancy colors, albeit colorful, we strive to capture the relevant physics ruling the fluid behavior and therefore, on our portfolio we have compiled a list of different topics each benchmarked with experimental data or validated studies. For instance:

Heaving suction bucket in the splash zone: During the installation of jackets with suction buckets, the typical methods using diffraction software can be less accurate since the radiation problem does not consider the transient behaviour of the bucket, especially close to the free surface as the entrapped air creates a cushioning effecr. This can lead to less accurate etimates of natural modes and impact DAF values , operability and/or workability figures, important for the HLV contractor.

Ship roll damping: For the assessment of vessel motions, it is typical to compute the RAOs with diffraction software which are known to underpredict viscous damping effects. Obviously, since it is based on an inviscid formulation. To compensate for this problem, CFD can be used to compute the missing roll damping sources and thus update the hydrodynamic properties of the RAO. This will lead to a much realistic roll amplitude and potentially of the coupled terms as well such as surge amplitude.

Drag study: We believe this is one of the most classic problems within our industry. Estimating the drag coefficient on offshore structures is often reduced to simple geometries such as squares, cylinders, spheres, etc. While this is pragmatic and conservative, there are instances where such an approach can lead to overengineered systems with an unnecessary cost due to overpredicted loads. In this case, CFD can be used to get a more accurate estimate.

Breaking waves, runup and slamming on complex object: Effects of steep waves on offshore structures and impact loads are notoriously complex and are usually highly simplified with conservative recommended practice an guidance derived from empirical work. CFD helps to bridge the gap between lower-fidelity equations and models and limited experimental data.

If curious on how CFD can be determinant to your project or to discover the full extend of our portfolio feel free to reach out to our team. Part of our CFD portfolio is built with a streamline approach in mind so certain aspects have been parametrized to deliver results fast. We are also available for non-standard studies.

3rd Party Review

1. Lender’s engineering

As independent lenders’ engineers we provide clear, impartial technical assessments that bridge gaps between stakeholders and help resolve insurance or contractual disputes. We verify whether designs, tests and operations align with industry practices and whether the documented approach truly reflects the complexity encountered in the field. Our reports are concise, evidence-based and focused on material risks and mitigations — giving financiers and insurers the technical certainty they need to support decisions, close financing loops and reduce downstream claims exposure.

2. Project engineering — 3rd‑party review

Our project engineering reviews draw on broad experience across project documentation, execution and handover, supported by a long list of reference projects. We rapidly assess design packages, QA/QC records and technical interfaces to identify gaps, non-conformities and optimisation opportunities. With flexible, on-demand resourcing we integrate quickly into project timelines to de-risk schedules and budgets. Clients benefit from pragmatic recommendations that improve constructability, reduce rework and strengthen contractual clarity — accelerating delivery while protecting project value.

3. R&D — 3rd‑party review

For R&D programmes we identify which physical phenomena matter at each development stage and validate whether testing, modelling and assumptions are fit for purpose. We specialise in modeling novel systems and translating high complexity into actionable design criteria and go/no-go decisions. Our engineers are comfortable with high uncertainty and new technologies, focusing on the underlying physics to separate critical risks from secondary effects. This approach helps clients prioritise experiments, streamline development paths and increase confidence in innovation outcomes.
