SEA INSTALLER
Efficient and cost-effective A DECADE OF EXPERIENCE SEA INSTALLER reflects more DECK than a decade of experience in SEA INSTALLER's deck measures 3,350 m2 The deck is reinforced and can carry 15 t per m2 and a total load of 5,000 t The vessel can accommodate eight 3.6MW turbines or four 6MW turbines at a time SEA INSTALLER was built at the COSCO shipyard in China under close supervision by A2SEA s construction department SEA INSTALLER measures 132 m from stem to stern and the hull is 39 m wide SEA INSTALLER can operate at depths of between 6.5 and approx. 60 m (depending on specific site conditions) SEA INSTALLER weighs 20,000 t fully loaded offshore wind installation. Designed to operate in deeper waters further offshore, this purpose-built vessel transports and installs up to eight 3.6MW turbines. SEA INSTALLER takes the installation process to a more efficient and cost-effective level, giving developers greater confidence that their projects will be delivered on time and with maximum profitability. Semi jacked-up during installation in fine weather or when soil conditions are difficult Fully jacked-up during installation CRANE The crane on SEA INSTALLER is a fully electrical GUSTO GLC-800-ED The crane has a lifting capacity of 800 t or 2 x 400 t in dual lift In addition to the main crane, SEA INSTALLER also has five smaller cranes SEA INSTALLER has doubled A2SEA s capacity compared with the current fleet The crane will be upgraded to a lifting capacity of 900 t and a 120 m boom in 2014 The crane is mounted round one of the legs saving space compared with the layout of other vessels SEA INSTALLER can work in three different modes: Floating as an ordinary vessel during transport and loading of turbine components Photo: Paul Langrock, Gunfleet Sands 3
A huge amount of raw power is required on board SEA INSTALLER POWER ON BOARD Photo: Ole Risbjerg, engine room JACKING SYSTEM ENGINE ROOM The jacking system on SEA INSTALLER is a double, hydraulic system There are eight jacking cylinders at each leg, i.e. 32 in total The legs on SEA INSTALLER can be raised and lowered at a speed of 1 m/min The legs on SEA INSTALLER are 84 m long The spudcan on the legs measures 108 m2 per leg, i.e. 432 m2 in total A special jetting system at the bottom of the legs can flush the legs free of the seabed when they have to be raised. Depending on the soil conditions, the legs may have penetrated up to 21 m into the seabed, and without a jetting system, lifting the legs would be like pulling a rubber boot out of a mud hole SEA INSTALLER has six 3,020 kw engines SEA INSTALLER has three Voith Schneider propellers for propulsion and three bov propellers for satellitebased positioning The vessel can manoeuvre with a precision of 25 cm under optimum weather conditions In addition to the engine power required to sail SEA INSTALLER, the engine room supplies power to a special satellite-based navigation system also called DP (Dynamic Positioning), which can maintain a given position during operation with a tolerance of only 25 cm
Everything is controlled from the control room on SEA INSTALLER PRECISION CONTROL CONTROL ROOM BRIDGE An installation vessel like SEA INSTALLER has many electrical and pressurised systems, from the vessel s engines to the hydraulic jack-up system, ventilation systems, cooling systems and toilets, not to mention service water for up to 60 people. Everything is controlled from the control room on SEA INSTALLER. SEA INSTALLER can be manoeuvred from the bridge by a single person The bridge is 50 m wide and the total area measures 285 m2 There are five control panels on the bridge from where the vessel can be manoeuvred SEA INSTALLER can be manoeuvred in the so-called DP2 mode The advanced satellite navigation equipment makes it possible to manoeuvre SEA INSTALLER with 25 cm precision To be the chief engineer on board SEA INSTALLER is like being responsible for processes and systems in a small Danish village. To help the chief engineer with the monitoring, SEA INSTALLER has installed an Integrated Control Ship System (ICSS). The advanced computerbased ICSS system helps monitor and control temperature, power consumption, water consumption and oil pressure. Photo: Ole Risbjerg, the bridge on board SEA INSTALLER
Life on board an offshore vessel can be tough, so we spoil our clients and crew when they are off duty CARING FOR CLIENTS AND CREW MESS, GALLEY AND CINEMA The mess on SEA INSTALLER is open 24/7 It is prohibited to drink alcohol on board SEA INSTALLER A special office is available where guests on board the vessel can work undisturbed LOUNGE AND CABINS SEA INSTALLER can accommodate 60 crew members and guests Everyone on board has a single cabin The crew and any customers on board share the same lounge and cabins It is not permitted to wear work clothes in the lounge area and in the cabins CHANGING ROOMS AND GYM FACILITIES COMFORT ZONE Installing offshore wind turbines can be a wet and dirty job, so the clients and crew need good facilities for changing Photo: Michael Best, crew on board SEA POWER and showering we call these the Comfort Zone. The Comfort Zone is used for changing from work clothes to leisure wear, and facilities are provided for relaxation and exercise before continuing to the lounge area or private cabins. CLEAN ZONE It is prohibited to bring work clothes to the individual cabins. We therefore also have a Clean Zone, where it is not permitted to wear work clothes. The changing room facilities make it clear that SEA INSTALLER maintains a high standard throughout the Comfort Zone. Much attention has also been paid to the gym facilities. Here the clients and crew have plenty of opportunities for weightlifting and fitness training if the wait becomes too long.
We can ensure the highest standards of safety and quality POWERED BY KNOW-HOW A2SEA provides offshore wind transport, installation and service solutions at a wide variety of locations. We specialise in providing the offshore wind industry with safer, sustainable, and more cost-efficient operations through know-how, seamless integration of installation and service solutions, and quality of performance. Anyone can hire a vessel. Having the right people and know-how is what makes it a success. SAFETY FIRST Quality and safety are central to everything we do at A2SEA and all processes we carry out are characterised by the same objectives; Safety first, No accidents or incidents and No damage. Our safety and quality policies are clearly defined and integrated in all our operations. We also enforce a No blame policy to encourage the reporting of all incidents. The overall objective is to become even better by knowledge sharing and thus learning from incidents. TEAM BUILT You ve specified the right equipment. And chosen an experienced installation contractor with the know-how to do the job. But that s no guarantee of a smooth-running, on-time and on-budget result. There s something else you should be looking for in the partner you choose: superior teamwork. The way we see things, installing a foundation or turbine takes every bit as much teamwork as winning a Formula One race. It is the vessel itself, the crew on board and all the engineers, planners and support staff that make it possible. Everyone contributes to the success.
