Suction Bucket installation operability analysis
The focus in this project was on accurately model the dynamics of the Suction Bucket Jacket (SBJ) during two critical installation phases: splash-zone crossing and landing onto the seabed. In addition, overall workability was evaluated. We developed detailed aero-/hydrodynamic models to simulate the SBJ’s descent through the splash zone, along with a coupled hydrodynamic and geotechnical model to […]
Four-point mooring analysis for anchor retrieval
This project comprised the analysis of an anchor-loss incident on the North Sea during a diving operation and the evaluation of the four point mooring procedure. During this project there was a high urgency for engineering advice with regards to an incident leading to anchor loss during a pipeline inspection diving operation. The mooring procedures were evaluated to avoid future […]
Ocean Cleanup’s Interceptor Mooring Analysis
Mocean has supported the Ocean Cleanup with mooring design and analysis for the interceptors in Dominican Republic, United States, Malaysia and more. Along with validation studies, design support of novel barriers and the design of buoys. During this project, Mocean supported with designing the barriers and buoys. Time domain simulations were conducted to determine the dynamic behavior of the barrier and […]
Heave plate hydrodynamic verification using CFD
Heave plates are widely used in the industry to influence behavior of floating bodies. This includes e.g. reducing platform motions for Floating Offshore Wind Turbines. At Mocean we recognize the benefits of correctly understanding and representing their influence in our analyses. Using OpenFOAM this study verified accurate representation of the hydrodynamic coefficients of a heave-plate design. Client: Internal / Mocean Offshore
Floating installation of Arcadis Ost 1 OWF
Arcadis Ost 1 is the first commercial offshore wind project installed with a floating installation method. Parkwind Ost GmbH contracted Heerema Marine Contractors (HMC) for the loadout, transport and installation of the WTGs. Mocean assisted HMC with the installation analysis. Mocean assisted HMC with wind turbine component lift analyses, determining design loads and expected motions for their novel full RNA lift method. […]
Floating solar feasibility evaluations
Multiple Floating Solar concepts were analyzed in a qualitative assessment during support of TNO’s reviewing process towards HKN. An MCA was performed for five different concepts to evaluate the feasibility in different aspects; the floaters robustness, the interconnections’ robustness, the mooring systems robustness, risk of fouling, access and egress and finally the required footprint area. By doing this, […]
Kelp farm design
Mocean Offshore supported Kelp Blue to improve ocean health and absorb CO2 by evaluating a pilot farm’s design near Namibia. They focused on durability in harsh weather and recommended redesigns to enhance safety and reduce costs. Mocean Offshore has supported Kelp Blue with engineering in their endeavour to restore the health of the oceans and lock away vast amounts of CO2. The […]
FOWT Platform design
Mocean supports maturing the design of a deep water floating wind platform for ECO TLP. The support includes floater design, improvements on the mooring system, overhaul of the installation methodology and development platform-specific cost modelling, as well as a scale-model test campaign performed at MARIN. Mocean leads the technical package for this innovative project, which has included responsibility for the process to receive […]
Mooring and motion analysis for HLV Gulliver
Mocean Offshore performed a mooring and motions analysis for HLV Gulliver during a decommissioning campaign. Conduct mooring and motion analysis for Heavy Lift Vessel Gulliver during a decommissioning campaign. The scope entailed a mooring and motion analysis for a total of 13 lifts (topsides and jackets) during lift and transport operations. Results of the scope are workability tables for […]
Quad lift for Hinkley Point
Detailed multi-body (3) heavy lift analysis involving a quad-crane-lift operation and fully coupled mooring response in extremely shallow water and high current conditions. As a part of the cooling system of a nuclear power plant; large concrete intake and outfall heads had to be installed on the seabed. The lift was performed by Scaldis with the Rambiz and Gulliver heavy lift vessels. […]
