emission reducton levels Bakker Sliedrecht electrifes Heerema’s
Sleipnir and Thialf moored in the Calandkanaal in the port of Rotterdam.
BAKKER SLIEDRECHT WILL ELECTRIFY THE CRANE VESSELS THIALF AND SLEIPNIR OF HEEREMA MARINE CONTRACTORS SO THAT THEY CAN BE POWERED WITH GREEN SHORE POWER. WIND TURBINES AT THE QUAY OF THE CALANDKANAAL IN THE PORT OF ROTTERDAM WILL GENERATE THIS SUSTAINABLE ENERGY. THE SHORE POWER CONNECTION ALLOWS THE VESSELS TO TURN OFF THEIR DIESEL GENERATORS, WHICH SIGNIFICANTLY REDUCES NOISE AND CO2, NITROGEN, SULPHUR DIOXIDE, AND PARTICULATE MATTER EMISSIONS.
The electrifcaton of the vessels is part of a shore power project that, alongside Heerema, also includes power company Eneco, the Port of Roterdam Authority, and the City of Roterdam. As part of the project, nine modern wind turbines with a total capacity of 27MW will replace ten existng wind turbines, the project consortum in August 2020 started building a so-called e-house on the quay near the canal. This is a gigantc socket that can supply 20MW (2 x 10MW) of green wind energy.
5,000 diesel cars
Heerema is their frst client. The ofshore company’s Thialf and Sleipnir are the largest crane vessels in the world. About 400 people can live and work on board. During the winter period, the crane vessels are regularly moored in the Calandkanaal for maintenance or in preparaton of projects at sea. All on-board facilites are then powered by diesel generators. By connectng the ships to sustainable shore power from the new e-house, they can be turned of. This will reduce the amount of emissions equalling 5,000 diesel cars. CO2-emissions will be reduced by 15,000t and the vessels will be virtually silent.
On-board modifcations
To use this sustainable shore power, Bakker Sliedrecht is presently carrying out various adjustments on board. The company will, among other things, supply the required transformers, shore connecton switchboards, and interface to the existng power distributon system. The enterprise will also expand the existng installatons and switchboards and install the low and high voltage cables. The voltage must be converted from 11kV to 4.16kV. All new equipment will be installed on board of Thialf early next year, upon which the work at Sleipnir will commence. This crane vessel is brand-new, which means fewer electrical adjustments and a less extensive work package.
Long-term relationship
Heerema consciously opted for Bakker Sliedrecht. “We have a long-term relatonship together. We are Heerema’s preferred supplier and have supplied signifcant parts and equipment for the crane vessels, varying from switchboards to generators and also propulsion systems”, says Project Manager Andy Waterstreet and Account Manager John Hollemans of Bakker Sliedrecht. The constructon of electrical infrastructure on vessels and land installatons is a specialty of Bakker Sliedrecht, whether it concerns high, medium or low voltage. In additon to Heerema’s crane vessels, more vessels and other companies in the port of Roterdam will be able to use the sustainable shore power in the future.
