Exploring the undiscovered path Editorial: Annabelle Withering

Hollandia Offshore is intent on providing and offering reliable and resilient solutions for the day-to-day and for the unavoidable challenges of tomorrow – “For generations these are the challenges that inspire us to exceed ourselves.� With extensive knowledge and experience, the company refreshingly looks to push the boundaries within the offshore steel construction industry, providing a reliable and innovative solution.


HOLLANDIA OFFSHORE Forming the backbone of so many of the structures that surround us today – much of mankind’s development and prosperity would not have been possible if it weren’t for one of the most widely used metals: steel. Having a major impact on our daily lives, the durability, versatility and strength of steel makes it a continually firm choice for contractors worldwide. An easily adaptive and recyclable material, steel poses many other benefits – namely, that it has helped to reduce carbon emissions in construction significantly since the 1980s. Not to mention that it boasts low production costs, is easy to weld, corrosion resistant and hot and cold formable. Used in a magnitude of constructions, you only need to look around you to see its presence – in the cars we drive, the buildings in which we work and call home, the tools we use in our daily tasks and the natural gas pipelines supplying us vital energy. Hollandia, headquartered in The Netherlands, has been contributing towards the European steel evolution since 1928. Working in an array of different industry sectors, including the petro-chemistry and power station industry building complex and extensive offshore installations - Hollandia also work on operation sites, warehouses and factories and in non-residential construction projects which involve large shopping mall builds and car parks.

An ideal partner of choice for the maintenance and management of steel constructions, Hollandia provides clients with the design, engineering, production, manufacturing, transport and assembly of steel constructions, high-tech systems and half fabrications. Established in 1928 as a subsidiary of Amsterdamse Ballast Maatschappij, Hollandia has undergone many acquisitions and mergers since the 1970s with Kloos Kinderdijk, Bailey Nieuw Lekkerland, ZNScompanies Fijnaart, Grimbergen Alphen aan den Rijn and Kalmar (Nelcon) Rotterdam. However, in 2005, Hollandia’s associate companies, Bailey and Grimbergen came together with Hollandia under a single umbrella at the former Van der Giessen-De Noord site at Krimpen aan den IJssel. Three years later and Hollandia and ZNS fully merged to form Hollandia. Hollandia Offshore, with its head office at Krimpen aan den Ijssel, also has a branch office at Heijningen in the southern region of the Netherlands. The division exercises its offshore expertise and services in the oil & gas sector, offshore equipment and wind energy industry. Offering a turnkey solution to oil & gas customers, Hollandia Offshore takes responsibility for the entire project, from the initial design, through to final realisation, ensuring both the logistics and cost efficiency. With over eight decades working within the steel industry, Hollandia Offshore utilises this knowledge to

both design and construct the essential components for offshore vessels – maintaining its long-standing reputation for quality and reliability, solutions include parts for stingers, J-Lay towers, fixation systems, jackets and heavy-lift cranes. The company explains: “Our project organization is well acquainted with the specific safety regulations of (petro) chemistry industries and powerstations which is why we can deliver all sorts of steel constructions for crackers, equipment, operating platforms and pipe bridges. If desired, provided with roof- facade sheeting, doors, windows and additional finishing. In addition we construct and deliver onshore modules like PAU’s and PAR’s, for example, LNGterminals.”

OFFSHORE WIND ENERGY With the demand for sustainable and reliable energy dramatically on the rise, Hollandia Offshore has placed its experience into the development and construction of the offshore wind energy industry, proving its longevity as a trustworthy and knowledgeable contractor for transformer substations, essential in offshore wind developments. Even though the installation of offshore wind turbines requires a much higher initial investment compared to onshore wind farms, the results are certainly considerable. Inviting higher levels of reliability and steadier yields, this means an increase in full-load hours and so produces a significantly higher yield per turbine to onshore wind farms, in comparison. In 2009, the Strukton-Hollandia


Joint Venture was established by Strukton Systems bv and Hollandia bv. Integrated with the aim of becoming a reliable and resilient partner for wind farm operators and investors for the turnkey delivery of offshore high voltage substations – one such project is the DanTysk offshore wind farm, located 70km west of the island Sylt, in the German EEZ. A joint venture between Vattenfall (51%) and Stadtwerke München (SWM) (49%), the project consists of 80 turbines, each supplying 3.6MW. The


development hopes to produce enough electricity to power over 200,000 homes annually and reduce CO2 emissions by an estimated 412,000-tons every year. CEO, Dr Florian Bieberbach at SWM, said: “In terms of capital investment as well as installed capacity, DanTysk is our largest completed renewable energy project to date.” Officially commissioned in April of this year, with a reported investment of EUR 1 billion, the first turbine for the project was installed back in April 2014 with the last installed just four months

later. All 80 turbines were supplied by Siemens, also responsible for the supply, installation and commissioning of them. “We’re very pleased to be able to report the beginning of power generation from DanTysk,” said Gunnar Groebler, head of renewables business in Continental Europe/UK at Vattenfall. “With this project and its sister project Sandbank, which will follow in 2015, we are making a significant contribution to the further expansion of renewable energy in Germany.” Strukton-Hollandia was contracted for the engineering, procurement, installation and commissioning of a fully enclosed, sea water cooled 288MW offshore substation for the DanTysk project. Responsible for the transportation of the power

HOLLANDIA OFFSHORE produced by the 80 turbines to a MVDC converter station, it forms part of Sylwin Cluster’s grid connection. Power is then transported to the mainland via a 210km direct current (DC) cable to the Büttel substation, before it is fed into the German extra-high voltage grid. The substation has been designed with three decks, a helicopter landing pad and due to its location from shore, it also includes a petrol station. Completed and installed in August 2013, the substation construction took two years – leaving Hollandia shipyard in Krimpen on July 23rd the same year. Oleg Strashnov, the heavy lift vessel, was used to attach the 3200-ton topside to its

jacket foundation at the offshore development site, which took just under a week to complete with the aid of 200 workers.

NOTABLE CONTRACTS With a strong focus on leadership, Hollandia Offshore believes in exploring the undiscovered path, offering reliable and strong solutions not just for day-to-day, but for the inevitable challenges of tomorrow. Its main base in Krimpen aan den Ijssel is in a leading and highly competitive position fully equipped with different modern production halls, the latest tools, laser and paint facilities, ample storage space, dock, offices and a sit

out square, it now stands as one of the world’s very finest production facilities spanning across 13000m2. Conveniently located, the North Sea is within easy reach of the site, directly connected through the surrounding rivers. The hub also allows the company to fabricate structures up to 4000-tons – fabrication halls 10 and 11 are 40m wide and 80-100m long. The Strukton-Hollandia joint venture took shape once more as it was contracted for the Riffgat wind project – responsible for the turnkey delivery of the offshore highvoltage substation to the development site. Located within the 12-nautical

Sif Group is leading in offshore foundations. To stay in this leading position Sif Group decides to expand. Again.

But this time we have made the decision to expand closer to your and our core-business. In Rotterdam, an assembly hall and a coating hall will be built at Maasvlakte 2. The headquarters of the Sif Group will remain in Roermond. Our production possibilities? Production capacity of 4 to 5 XL monopiles per week up to 11 meters and a maximum weight of 2.000 tons including a dedicated monopile coating hall. Follow our progress at

miles zone at the North Sea, the Riffgat site has been built northeastern of the Dutch island of Schiermonnikoog and is owned and operated by EWE (90%) and ENOVA (10%). StruktonHollandia’s contract involved the engineering, fabrication and offshore installation of the 33/155 kV high voltage substation to connect the 30 3.6MW wind turbines to the German grid. Fully commissioned in March 2014, the first turbine was initially installed in May 2013. With an investment of an estimated EUR 480 million, Siemens was contracted to install, connect and commission the 30 wind turbines with an additional five-year maintenance

plan in place. The total installed capacity of the 113.4MW wind farm, recently upgraded from 108MW, is expected to supply 100,000 German households with reliable and eco-friendly electricity – the wind farm has now been supplying to the German grid since February 2014.

CLOSE RELATIONSHIPS Contracted by Saipem, subsidiary of global Italian giants ENI, Hollandia Offshore undertook the fabrication and outfitting of three stinger sections for the Castorone vessel. A dynamically positioned deepwater iceclass pipe laying barge, it has been designed for operations in locations and environments

HOLLANDIA OFFSHORE which are particularly harsh and unwelcoming. Last year, it was employed on the 219km-long Walker Ridge oil export pipeline, which connects Chevron’s Jack and St Malo fields in 2,140m of water, north to a Shell-operated platform in Green Canyon block 10. Building a successful relationship with Saipem, Hollandia Offshore was contracted once more to deliver the first pair of cable crossing sleepers for the South stream gas pipe line project in October last year. An efficient delivery, both sleepers were loaded following just a two month period for fabrication, painting and assembly. The company attributes the efficiency of the high quality steel fabrication project to the very close cooperation between the Hollandia project management team and Saipem technical staff. In a separate contract for Saipem, the great S44 launch barge left the quay of Hollandia Offshore last October following a total installation of 2300-tons of new steel with the loading of new and modified skid beam sections, outrigger girders and both the starboard and port side rocker arms. At a total length of 190m, a width of 50m and depth of 11.5m, the S44 is by far the largest barge ever to moor at the Hollandia Quay. The S44 is scheduled to launch the enormous Mariner Jacket in the summer of 2015. In March this year, Hollandia Offshore was appointed by the Danish power transmission company, Energinet.dk, with the procurement, fabrication, load out and transport of the Horns Rev C Jacket, which is to be installed on the Horns Rev 3 Offshore wind farm, located off the coast of

Denmark. Scheduled to be delivered in April 2016, the jacket has been designed for water depths of 16.5m with a structural weight of 1600-tons. A 4-legged space framed jacket with leg piles, the stability of the jacket has been provided by suction cans that are placed on each corner during pile driving and grouting. The project is being undertaken at the Hollandia Offshore’s Krimpen aan de Ijssel yard with most of the fabrication works taking

place indoors in one of the company’s newly built fabrication workshops. Managing Director of Hollandia Offshore, Nico Noorlander, said of the project: “We are very pleased to receive this award from Energinet. It strengthens the position of Hollandia Offshore as one of Europe’s leading fabricators for offshore structures for the wind industry. We look forward to working together with Energinet on this project and to develop the relationship further for future projects.”
