Dutch engineering and consultancy company, Enersea, has reported that its engineering team is rendering fabrication support during the manufacturing of the cable lay street for Tideway’s new multipurpose vessel Living Stone.
Previously, Enersea was working on the concept, basic and detailed mechanical design of the vessel’s deck layout and equipment. The company said it also specified the control, hydraulic and electric systems and assisted in the tendering process.
One of the design criteria demanded that the configuration of the vessel could be quickly changed from cable-laying into precision rock placement.
With the modular design of the cable installation system, this is possible within days, Enersea stated. Different configurations, with short turn-around times, are possible depending on the cable requirements. The cable lay system can also be easily transferred to a different vessel, the company said.
The two 5,000-tonne cable/umbilical turntables are stationed below deck, leaving a 3,500m² free deck that can accommodate different cable lay configurations.
Apart from the cable lay street, the deck can accommodate a fall pipe system, ROVs, subsea trenching tools and a 700-tonne crane. The vessel is also fitted with a 7.7 by 7.7m moonpool. The design of the cable lay system has been focused around cable and CPS logistics. According to Enersea, this makes the Living Stone unrivalled in the current market with regard to cable installation efficiency.
On the quayside of the new Reimerswaal shipyard in Vlissingen, the Netherlands, Tideway will first test the complete cable lay street before it will be installed in modular sections on board the Living Stone.
Enersea engineers will be involved in the project during the fabrication and mobilisation phase of the deck equipment.
