A previous work at Royal IHC, following the observation from sea trials of trailing suction hopper dredgers (TSHD) that the turning performance of bow tunnel thrusters significantly reduced at slow forward speeds, studied the flow behaviour and performance of bow tunnel thrusters at slow forward speeds using Computational Fluid Dynamics (CFD)....

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 cranes are often equipped with a safety system, the Automatic Overload Protection System (AOPS), which should prevent cranes to be overloaded during lifts from load supporting structures with a relative movement. Yet, a crane is still exposed to a peak load as a result of the AOPS’ behaviour. Using an iterative method, a simulation...

Offshore pipeline installation is limited by pipeline integrity during the laying process. Pipeline integrity is evaluated with the help of buckling checks, which help determining the feasibility of pipeline installation for a given sea condition. The operational limit of pipeline installation is determined during project preparation, by...

Pioneering Spirit, Allseas newest vessel, is specialised in offshore platform installation and decommissioning. The goal of this research is to find a solution for the interface between the topside lifting system and platform jacket legs without the necessity of lengthy preparation work to platform. In a research regarding platforms...

The present study investigates the implementation of energy storage devices on board a vessel which functions in dynamic positioning mode at some part of its operational profile. For the purpose of deriving quantifiable results the paradigm of a platform supply vessel is utilized. In order to conduct this analysis there were four steps that were...

Heerema Marine Contractors is looking into a new semi-submersible crane vessel concept with an asymmetric hull. The necessity of braces (connections between the portside and starboard hulls) for this vessel is questioned, based on earlier vessel developments and operational experience. This study addresses the influence of braces on the...

Dynamic positioning has been developed for over half a century and is now widely used on board. However, the existing dynamic positioning system is not specially made with heavy lift vessels. This report is to solve the dynamic positioning problem during heavy lift operations. To fulfill this goal, the robustness and stability of the solutions...

Declining production, continuously rising cost levels, low oil prices and the subsequent declining reserves, are forcing the oil and gas industry to reduce its operating expenditures. This study focuses on how the best maintenance policies for the power generation on unmanned satellite gas platforms of Total Exploration and Production...

Structural blast analysis is usually done with two load levels for different design stages; the Strength Level Blast, SLB, and the Ductility Level Blast, DLB. Strength Level Blast is the lower magnitude overpressure (with a higher frequency of occurrence and lower consequence) and Ductility Level Blast is the higher magnitude overpressure (with...

One of the most dangerous events that can occur on an offshore topside structure is an explosion. If blast analyses is performed without taking plasticity into account, then it may lead to very conservative design. On the other hand monitoring the weight by optimising the structural design is an important design aspect of such structures....

In this master thesis the flow behavior and the performance of a bow tunnel thruster at slow forward vessel motion is studied using Computational Fluid Dynamics (CFD). The study analyzes the flow and the turning ability for a cylindrical cross-section and the effect of changing the cross-section of the bow tunnel thruster. At Royal IHC it is...
