GeoSea, DEME's offshore engineering division, has contracted Alewijnse Marine for the electrical installation of a helicopter deck on the Apollo. DEME’s newest and greenest Offshore Heavy Lift DP2 jack-up vessel to date was delivered to GeoSea in August. The works will take place in Q1 2019 following the completion by Apollo of a decommissioning contract in the North Sea and follows Alewijnse’s previous electrical system integration and automation works on board prior to her delivery in August.
For the new helicopter deck, Alewijnse will deliver and install upgrades of existing systems plus a helicopter monitoring system. In addition, a dedicated fire-fighting system will be installed, which can be operated from the bridge.
Earlier this year, Alewijnse designed, engineered and delivered a highly advanced vessel management system. This included an Alewijnse Draft & Loading system (ADLS), a tank sounding system (TSS), a power management system (PMS), various interfaces and a highly efficient riser and cooling water system. The addition of a sophisticated HD video and peripheral matrix switch system allows all connected systems to be easily controlled and monitored via the multifunctional touchscreens and other screens on the bridge.
The multi-purpose 87.5-metre Apollo has been designed for wind turbine and foundation installation, decommissioning and heavy-load transportation. She has been built to be one of the most environmentally-friendly vessels of her class but in the world and complies with the ENVIRO certificate, the most stringent class notation for environmental protection, awarded by the American Bureau of Shipping (ABS). Clean power on board is supplied by solar panels and wind turbines, and biodegradable grease and oil are also used, along with heat recovery techniques. Together, these technologies ensure that the vessel operates with the lowest possible fuel consumption while also keeping CO2, and NOx and SOx exhaust to the strictest minimum. A key card system for the accommodation units also helps reduce energy usage.
A leader in specialist electrical systems for the offshore industry
The Apollo project demonstrates the expertise that Alewijnse offers operators in the offshore industry in the design and delivery of all types of electrical installation across a wide range of vessels. Previously delivered automation systems for DEME include those for the Melina, Uilenspiegel and Lange Wapper. “I feel confident with this latest challenge, which extends the history of fruitful cooperation between Alewijnse and DEME, that it will result in the deployment of technically advanced solutions which contribute to the vessel’s strategic competitive advantage,” said Alewijnse product manager Johan van Rikxoort.
