KCI is at the forefront of designing for deck lay outs and specialist equipment in ship design, where early involvement in the process is critical. Next to complex structures for marine environment, we also design big fairground Ferris wheels. At the moment we are designing two new great wheels which will be the biggest in the world.

Specialties
Own design pile gripper for easy handling of monopiles during offshore installation • conversion of pipe lay to cable lay vessels and vice versa • robust design of stingers • smart design of inclined fall pipe system for rock dumping vessels • design & engineering of great Ferris wheels • supervision of onsite manufacturing & installation • procurement

Deck layout cable laying vessels

As a true back-deck specialist, KCI provides its customers a complete in-house service encompassing all prerequisites to design, engineer and manufacture equipment ranging from single components to complete marine handling systems. Customers like to involve KCI at an early stage to keep design options open so KCI’s creative and experienced engineers can come up with the best conceptual solutions. We love to spar with you from first ideas, can quickly deliver FEEDs, basic and detailed designs and can take care of fabrication & installation management.

KCI has been involved in a large number of cable lay-deck layouts. Ranging from smaller, project specific mobilisations to generic deck layouts of cable-lay vessels, such as Boskalis’ NDurance and Van Oord’s Nexus. For both vessels KCI has been involved from the conceptual stage to the detailed phase of designing equipment and vessel interfaces.

Modular turntable design

KCI performed several turntable designs to store cables and umbilicals. The turntables are modular and the parts can be transported in shipping containers for flexibility and quick mobilizations. The turntable capacities vary from 500 mT to 4000 mT. They can be used both for onshore and offshore purposes and are easy to assemble using bolts and pins.

Stinger Helix

The Ceaser is a pipelaying vessel from the company Helix Energy Solutions. In 2006 KCI performed the concept and detail engineering of the stinger that supports the pipeline during the pipe-laying operation. The stinger is supported by a hang-off frame and is equiped with an uplift compensation system that are also designed by KCI.

The length of the stinger is 92 m and has a minimum bending radius of 70 m and a maximum bending radius of 300 m. The stinger weighs approximately 950 mT.

Inclined fall pipe system

The design objective for the Inclined Fall Pipe System (IFPS) was to enable precision rock placement around the legs of fixed oil & gas platforms and offshore wind structures such as monopiles and jackets in shallow waters. With the normal rock dumping fallpipes these locations cannot be reached as the fallpipe is positioned through a moonpool in the centre of the vessel.

The IFPS, designed by KCI, consists of separate closed fall pipe sections which are modularly assembled from the aft deck. From the aft of the ship, the IFPS extends an inclined cantilevered pipe, reaching approximately 20 metres behind the vessel. Through this 50 metre-long pipe of 1.20 metre diameter, extremely precise rock placement is possible.

Jumbo Papa Terra, deck layout design

For Jumbo's Papa Terra project in Brazil, KCI was awarded the design and engineering of various deck lay out items for the transportation and installation of equipment for a Tension Leg Wellhead Plaform (TLWP). Jumbo was asked to transport 134 tendon segments with lengths up to 70 m and weighing 6000 mT in total, to an offshore location in Brazil. Subsequently these tendon segments had to be transferred to an installation vessel which had to install the TLWP mooring system.

KCI's scope for this project was to design and engineer a variety of seafastenings and installation aids required for on board storing and for handing over the tendon segments to the installation vessel. To this end, KCI designed special Hang Off Frames for both the Jumbo Javeling and the Fairplayer. For the Jumbo Javelin also tendon racks were designed. Finite Element Analysis to verify structural integrity of the steel design and the vessel structure for both heavy lift vessels was also part of KCI's scope. Further KCI rendered on-site fabrication support in the Netherlands and the USA to support and monitor the building of tendon racks and the Hang Off Frames. Also KCI engineers gave mobilization support on both continents and in-field installation assistance in Brazil to monitor and supervise the offloading of the tendon segments.

Pile gripper

Offshore contractor GeoSea was in search in search for a pile gripping solution for the installation of monopiles for Dong Energy’s Westermost Rough wind farm. These monopiles measured 60m with a diameter of 6.5m. Thus on the upper boundary of the spectrum of monopiles that have been installed up to today. They asked several engineering companies to come up with a good solution. KCI presented the best idea and won the project.

KCI’s pile gripper combines smart engineering with the latest in control technology. The pile gripper is designed and built for operations in harsh weather conditions and will hold the mono-pile foundations securely in place whilst they are being hammered into the seabed.

The biggest advantage of the KCI pile gripper is the simplicity of the design. With a static welded frame, less rotating parts and a lighter construction, it is a reliable and low cost solution both in terms of CAPEX and OPEX. On top of that, the performance surpasses all pile grippers available today. The KCI pile gripper compensates for both horizontal movements in longitudinal as well as transverse directions. Moreover these movements are absorbed independently from each other.
