Woodside, Pluto LNG Project
The flow reduction inside the trench for the Pluto offshore gas pipelines is determined by NS3. A range of trench widths, trench wall side slopes, and locations along the route have been modelled. The results have been analysed given a reduction factor on the near bed current speed and poor bed orbital velocity.
Otway Gas Pipeline
The design wave-current induced hydrodynamic forces on the Otway Gas Pipeline were calculated by NS3. The pipeline consists of a main pipeline and a piggyback. Various pipeline-piggyback geometries were analysed.
Breaking waves, Thornton Bank Offshore Wind Farm
Detailed analyses of wave loads on gravity based foundations from irregular waves with NS3
Installation of Gravity Based Foundation
Physical hydraulic model tests of the installation of the gravity base foundations for the Thornton Bank offshore wind farm, Belgium.
Thornton Wind Farm Model Tests
Physical hydraulic model tests of the installation of a gravity based foundation for the Thornton Bank offshore wind farm, Belgium. Refer to project 11710580
Wind Farm Scour Tests
DHI carried out a 3D series of model tests in order to establish the design basis for the scour protection for a GBS wind turbine foundation of the Thornton Bank Wind Farm, Belgium.
Extended Analyses of Wave Forces on GBS
From comparison of NS3 calculations of wave forces on a GBS foundation to forces estimated with the Morison equation it was found that typical force coefficients, CM and CD, gave a too small overturning moment. The coefficients are optimised to overcome this.
Calculation of Wave Force on GBS
Wave generated forces on the GBS for a wind turbine foundation were calculated using the CFD tool, NS3. Furthermore, bed shear stress amplification factors were estimated.
Tsunami Study for Angamos Thermoelectric Power Project
The water level and current conditions for intake and outlet structures for a power plant at Mejillonnes during tsunami events have been investigated by means of DHI's numerical model, MIKE21 HD.
Cartagena Wave Study
The purpose of the study has been to provide extreme wave heights for the design of an outfall near Cartagena. Wave hindcasts using MIKE 21 SW have been made for four artificial hurricanes. Furthermore, fetch diagrams have been applied.
Update of Environmental Design Data for Siri Platform
Update of Environmental Design Data for Siri Platform
Crestwing Model Tests
Model tests with the Wave Energy Converter (WEC), the Crestwing.
Anholt Wind Mill Farm, Denmark Environmental Impact Assessment
For the establishment of an approximately 400 MW offshore wind farm near Anholt in the Kattegat, Denmark, DHI and associates were commissioned to conduct an Environmental Impact Assessment (EIA) for the proposed wind farm including submarine cables and transformer platform.
Horns Rev 2 Transformer Platform
Production of fatigue design data at the position of the proposed transformer station at the offshore wind farm Horns Rev 2.
TEA Wave-in-Deck Load Calculation
The objective of the project was numerical wave-in-deck load calculations on the Tyra East A platform. The numerical model was calibrated based on physical experiments performed for the TEA before the wave-in-deck load calculations for the TEA platform.
Horns Rev 2 - Metocean Study
Provision of metocean design parameters for the wind park Horns Rev 2, located in the eastern part of the North Sea.
Wave Run-up on Wind Turbine Foundations, Horns Rev
During two storms platforms attached to the wind turbine foundations were damaged. NS3 was applied to study wave run-up and forces on the platforms, which are situated 9 m above mean sea level.
Evaluation of Drag Coefficients for H-beams
The wave impact on eight H-profiles was simulated by NS3. 40 different cases, with various spacing and inundation, were simulated.
Numerical Analyses of a Labyrinth Weir
Study of the performance of a proposed labyrinth weir to be used as spillway on a planned dam in Ecuador.
Hindcast of wave and current conditions for future gas pipeline between Finland and Estonia.
Borkum Riffgrund Offshore Wind Farm 1 and 2 - Metocean Data
Update of metocean study for the Borkum Riffgrund Offshore Wind Farm to provide extreme and operational parameters covering a total period of 14 years (1994-2007).
Iranian Seas Wave Modelling Project (ISWM)
The purpose of the Iranian Seas Wave Modelling Project is to provide the Ports and Shipping Organisation of Iran with a database of design wave data for the Caspian Sea, the Persian Gulf, and the Gulf of Oman.

Keppel FELS MSSAU-1 Semi-Submersible Platform - Model Tests
Calibration of environmental conditions (waves and current) for physical model tests with Keppel Fels MSSAU-1 Semi-submersible platform carried out by FORCE Technology at DHI's 3D Offshore Facility.
Marine Outlet from Mining Activities in Peru, Pre-feasibility Study
Assessment of the potential for building a marine outfall for discharge of process wastewater from the Antamina processing facilities at punto Puerto Lobito, Peru.
Platform Scour Protection, Sakhalin II, Phase 2
Model tests for the platform scour protection for two Gravity Based Structure (GBS) production platforms, PA-B and LUN-A, to be placed east of Sakhalin at 30 m and 48 m of water depth, respectively. The main scope of work covered testing of three types of scour protection design for each platform.
Tatar Strait Tidal Forecast
A pipeline connecting Russia to Sakhalin Island is proposed to be built. The pipeline will be built in a relatively shallow area, which necessitates the prediction of tidal level in the area in question. DHI was commissioned to deliver tidal and current forecast based on MIKE21 HD simulations. Tidal constituents were used as boundary conditions in the model.
Platform Scour Protection, Sakhalin
Model tests for the platform scour protection including evaluation of the stability of different scour protection layouts, assessment of the scour pattern of the surrounding seabed and evaluation of the stability of the filter layer during the installation phase
Arabian Gulf Metocean Database
The overall objective of the project was to develop a database of the metocean conditions in the Arabian Gulf and a graphical user interface (GUI) for the database. The database contains and gives users access to metocean data and statistics of same within the Saudi Aramco operational area of the Arabian Gulf.

Cyprus Water Supply Project
1) Hydrodynamic Experimental Investigations to support the design of the Cyprus Water Supply Project: Hydrodynamic Loads, Vortex Induced Vibration and Stability of the On-bottom to Free Span Transition. 2) Design Review of the preliminary and detailed engineering of the offshore section.
MCR-A Platform Model Tests
Physical model tests in the DHI offshore laboratory for a coupled system consisting of an installation barge and a Gravity Based Structure (GBS).
The seabed around the Khazzan oil storage tank has lowered so that a gap has formed between the bottom of the tank edge and the seabed up to 1.5 m. The objective of the study was to verify that the present gaps have developed due to scouring of the seabed over time. DHI's in-house CFD model NS3 was used to simulate the wave and current action around and under the tank. The results from the simulations were used to evaluate the present scouring and to design the gap closure.
