MANOEUVRING
MARITIME RESEARCH PROGRAMME
The programme’s objective is to support the maritime sector with the assessment and improvement of safety and efficiency of nautical operations and traffic flows, and to provide reliable and accurate hydrodynamic models.
SAFE NAVIGATION
The programme’s objective is to support the maritime sector with the assessment and improvement of safety and efficiency of nautical operations and traffic flows, and to provide reliable and accurate hydrodynamic models. These models can be used in concept, design and operation, and support the mission-oriented research programmes. The knowledge developments from this research programme will contribute towards solutions for zero-emissions (in cooperation with the Zero-Emission Shipping programme), zero maritime accidents (in cooperation with the Safe operations & Human factors programme), and more efficient operations (in cooperation with the Safe operations & Human factors and the Autonomy & Decision support programmes), using data science and one integral digital model.

sub programmes
NAUTICAL SAFETY
In this sub-programme, we want to enhance the use of all information “captured” within Automatic Identification System (AIS) data, in order to improve insight into the behaviour of ships at sea, in inland water ways or in ports.

VISCOUS BLUFF-BODY HYDRO- AND AERODYNAMICS
In this sub-programme, we develop prediction methods for hydrodynamic and aerodynamic forces on full-scale ships, offshore structures and multiple bodies at arbitrary motion and in arbitrary wind & current flows (steady/unsteady/stratified). Flow-induced motions of rigid bodies, such as vortex-induced motions (VIM), as well as vortex-induced vibrations (VIV), are included in this sub programme.

CONTROL DEVICES
In this sub-programme, we aim at improve the prediction and optimisation of the forces generated by control devices, comprising propellers, (transverse) thrusters, rudders, water-jets, pods, and including their interaction effects.

CONFINED WATERs
This sub-programme quantifies the effects of shallow and confined water on manoeuvring, current loads and ship-ship/ ship-bank interactions.

MANOEUVRING IN WAVES
This sub-programme aims to bridge the gap between manoeuvring in calm water and seakeeping. Forces during manoeuvring are mainly driven by viscous effects, while seakeeping aspects are traditionally modelled using potential flow theory. Reliable methods to combine the physics occurring when sailing in calm water with the physics of motions due to waves need to be developed. This developments will help in quantifying the effect of waves on the performance, controllability, and safety of ships.

REFRESCO OVERTAKING INLAND SHIP
Complicated interactions with the environment and the other ships happens when overtaking happens in confined and shallow waters. An overtaking manoeuvre with two 110m inlands ships was successfully explored with REFRESCO in 2021, giving exceptional insight in the trim and sinkage of the ships.
REFRESCO-XMF VERTICAL ZIG-ZAG
Submarine free sailing manoeuvres can also be simulated in fast time and with high accuracy thanks to the coupling between MARIN CFD code ReFRESCO and time domain simulation framework XMF.
ReFRESCO-XMF coupling zig-zag manoeuvre
Most ships have to comply with the IMO requirements on the zig-zag and turning circle manoeuvres. These manoeuvres can be simulated in fast time and with high accuracy thanks to the coupling between MARIN CFD code ReFRESCO and time domain simulation framework XMF.
ReFRESCO crabbing operation
Crabbing is the ability of a ship to move sideways when approaching or leaving a quay. This is especially important for cruise ships and ferries because they often enter and leave harbours without assistance of tugs. CFD is a powerful tool to understand the complex flow features during a push-pull manoeuvre, as presented in these videos, and therefore help to evaluate crabbing operations.
