Pioneering Spirit, Allseas's largest pipelay vessel, will be outfitted with a novel Jacket Lift System (JLS). A jacket refers to the steel frame which supports the topside of a fixed offshore platform. The Pioneering Spirit was already capable of lifting the topsides of offshore platforms, like the former oil platform Brent Delta, but would have...

This master thesis describes a method to determine the workability of an offshore heavy lift operation. By creating wave realisations based on and statistically equivalent to measured ocean weather data, a quick assessment of the risk of failure can be achieved.

In this thesis the differences between the monohull and semi-submersible are investigated. For a general heavy lift crane operation and its operational profile, the difference is performance and total cost are calculated. These are used to determine the turning point, the point where the semi-submersible is more favourable for a heavy lift crane...

Ship to shore (STS) cranes handle millions of containers every day. One of the latest products from Stinis is the Split-Headblock. This device allows its user to work in tandem operation in which up to two 20ft or four 40ft containers can be lifted at once. In order to further increase the performance, it is important that it can be accurately...

The offshore wind industry is rapidly growing, and so is the competition in this market. Normally, offshore installation companies receive a subsidy for building offshore wind farms, but due to multiple companies bidding to install for lower and lower subsidies, the point where wind farms are installed without subsidy has been reached. Therefore...

Mercurius Shipping Group invested in two container-crane vessels which are able to load and unload cargo to and from its holds. Due to their unique feature, the crane, failure of the vessels results in large financial consequences. Previous experience showed that these costs could be mitigated with easily/timely available spare-parts. The main...

Offshore wind farms are a sustainable source of energy, but these farms require maintenance which is very expensive using the current techniques. Huisman Equipment B.V. proposed a new type of offshore motion compensated crane that is capable of reaching the height of the nacelle of these wind turbines. The crane has a compensation system on the...

For decades crane standards are used to assess crane fatigue making use of a static method in combination with factors to take dynamic load effects into account. This is not sufficient to make more accurate predictions. The proposed method benefits from state of the art Multibody Dynamics simulation tool Msc ADAMS and Finite Element software...

When working offshore on a floating vessel, the vessel will be subjected to wave induced motions and with a moving crane tip, a suspended load can start to swing. When the motions of the load become too large, the operation is interrupted. Alternatives such as jack-ups, function as a fixed platform to which the crane is attached, therefore...

During the studio Delta Interventions, I designed an intervention based on research within the San Francisco Bay Area. Basically, my intervention is about transforming historic real estate along the waterline and creating a new relation with the water. The intervention is mainly focusing on transforming a landmark in to a building that...

Jumbo maritime has almost 50 years of experience in the heavy shipping industry. In the past two decades Jumbo has developed into an offshore installation company by equipping the Fairplayer with a DP2 system. The Fairplayer has two 900 [ton] Huisman cranes. However, due to insufficient static stability a stabilization pontoon is required to...

Nielsen, D.Y. (author)
The handling of a payload by a crane at sea poses numerous challenges. One of the main technical challenges is the movement of the vessel due to the hydrodynamic forces exerted by the waves. The resulting heave, pitch, and roll of the vessel results in time-varying crane-tip motion. This motion propagates to the payload through the rope and this...

In order for Jumbo to stay competitive in the offshore market, it's heavy lift vessels should be able to take on a wide range of lifting purposes. This can range from installation of transition pieces for wind turbines to installing modules of fpso's and platforms. One of the demands from the offshore market requires large lifting heights. It is...

Heerema Marine Contractors operates large crane vessels, which are exploited for installation works in the offshore oil and gas industry. The benchmark power system of these crane vessels is diesel electric meaning that the main engines are driving alternators for generating electric power. But due to spiky power demand and strict redundancy...

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...

The trend in Offshore Engineering is towards exploring in deeper waters and more harsh environments. As a consequence, topsides become larger and heavier. In order to keep up with the demand for more lifting capacity, Heerema announced a New Semi-submersible Crane Vessel (NSCV). This vessel will contain two 10 000mt Tub Mounted Cranes (TMC),...

Crane companies face difficulties when installing blades of wind turbines: the tall cranes required for installation have large sail areas and are unable to lift 80% of the time due to too high wind speeds. Also load control by men from the ground is limited in high winds. To design a new installation method, enabling more lifting days per year...

Yard crane scheduling is one of the operational optimization problems that arise in a port container terminal. Multiple cranes have to store containers in the yard or retrieve containers from the yard. The scheduling of these cranes is complex and it is difficult to find an optimal schedule within limited computation time. In this thesis...
