Moored vessels in harbours around the world are affected by waves penetrating into the port basin. Hydraulic conditions can lead to severe vessel motions that influence the (un)loading efficiency and can even lead to the failure of fenders and mooring lines, creating unsafe situations for operating staff and <br/>A DMA is a chain of numerical...

This master thesis presents the computation of free-surface flow phenomena with emphasis on ship hydromechanics. We perform a simulation of the heave and the pitch motion of the DTMB 5415M ship moving in head sea. To this purpose we employ an existing Arbitrary-Lagrangian-Eulerian residual-based variational multiscale method (ALE-RBVMS) to...

The comfort assessment of ships is based on several criteria. There are for example criteria for motions, noise and vibrations. The criteria for motions are nowadays often defined as comfort limits on the accelerations in the ship motions. However, from other industries it followed that the rate of change of the accelerations, the jerk, can also...

With many operations at sea carried out by ships or or other floating vessels, risks are involved because of the waves and resulting motions of the ships. Examples are the landing of helicopters on ships, transferring crew from a ship to a wind turbine, or working on the deck of an anchor handling tug. It is common practice to assess the...

To compensate the heaving motion of a payload during deep water offshore installations, hanging from an on-board crane on a monohull vessel, a new concept is being investigated. By actively rolling the vessel using ballasting systems, the coupled heave motion of the crane tip can be reduced significantly. This is investigated by building a...

Offshore wind turbines are growing significantly to become a cost-effective alternative for the offshore oil and gas market. This causes rapid growth of offshore wind turbine foundations (monopiles). Currently, monopiles are installed using jack-up vessels like Aeolus. However operations will be limited by crane capacity and its cost...

During rough wave climates, vessel motions prevent people to be transferred safely form and to an offshore structure. The Ampelmann system is a ship-based, self stabilizing platform that actively compensates all vessel motions to make acces to offshore structures safe, easy and fast. The Ampelmann system uses a Steward platform to compensate...

The Damen Crane Barge type CB6324 is a transhipment barge, designed to operate in harbours, inshore and in near coastal waters worldwide, mainly for the on- and offloading of bulk carriers. In the second generation of this crane barge, optimization of the equipment and overall design is sought, increasing usability of the barge and reducing...

Dynamic analysis of the stinger hang-off system cable forces using ship motion data of Audacia. Already for some time the desire exists to acquire insight into the phenomenon of stinger uplift. This is the situation where external forces and motions acting on the ship, stinger cause the hang-off cables to have no or barely any cable tension....

Heerema Marine Contractors (HMC) operates several crane vessels, barges and tug boats for the transportation, the installation and the removal of offshore facilities. To achieve safe and successful projects, the accurate prediction of vessel motions is of great importance. Vessel motions are calculated on the basis of wave energy spectra and...

The demand to sail at high forward speeds in both calm water and in a seaway remains high. For various patrol, search and rescue or military operations attaining high forward speeds is essential. In head and bow quartering seas, the main factor for voluntary speed reduction is the occurrence of large vertical peak accelerations. The occurrence...

In recent years, great progress has been made in both the optimisation of the seakeeping behaviour of fast ships and the development of efficient numerical methods for computation of the seakeeping behaviour of ships in general. The study presented in the thesis aims to integrate both developments. First, the key aspects of the seakeeping...

Designers of maritime container terminals often experience difficulties in defining an acceptable degree of moored ship motions at the terminal to allow efficient (un)loading of container vessels. PIANC has published criteria for the principal movements of certain types of moored ships in harbours in relation to (un)loading efficiency (PIANC,...

In this paper, an integrated computational procedure for simulation of two-phase flow as well as floating and submerged body motions is presented based on a Volume of Fluid (VoF) - fractional step coupling. Two fluids are modeled as a single continuum with a fluid property jump at the interface by solving a scalar transport equation for volume...
