The Wadden (West Frisian) islands in the North Sea are one of the Netherlands’ top tourist destinations. The ferries that serve them operate 365 days a year, making multiple crossings each day across the Waddensea. For more than two decades, each year in January and February two of the main ferry companies, Wagenborg Passagiersdiensten and Rederij Doeksen, have taken advantage of the quiet period to send their RoPax vessels in relays to Damen Shiprepair Harlingen (DSHl) for maintenance and repair.
In January/February 2019, eight vessels from the two companies, ranging up to 75-metres in length, visited DSHl for periods of up to three weeks. This year the works were mostly exterior, involving, amongst other things, high-pressure cleaning and painting, though interior maintenance including the servicing of some engines and propulsion systems also took place. Selective refurbishment of the public areas also occurred on some of the ferries. In some years the works are more substantial and can include projects such as vessel lengthening.
DSHl is ideally situated for ferries and other vessels operating in or passing through the Waddensea and is the closest for these ferries’ particular routes. Ferries operate to the strictest timetables set many months in advance – in this case contractually with the Dutch Government – so unscheduled downtime is simply not an option.
With the islands becoming ever more attractive as tourist destinations, the numbers of visitors is growing and the off season is shrinking in length, putting even greater pressure on the vessels. For DSHl this means that almost every hour counts when it comes to maintenance. Only the most detailed planning and precise project management allows the yard to achieve such challenging goals and so support its customers in their own battle to deliver the transport services on which so many people depend.
达门Oskarshamnsvarvet修船公司（DSO）赢得了一份公开招标，将承担Waxholm II号客运渡船的使用寿命延长项目。这艘35.5米长的渡轮建于1983年，可运载350名乘客，由负责大斯德哥尔摩地区公共船只运输的公共管理机构Waxholmsbolaget公司运营。Waxholm II号计划于2019年4月1日抵达DSO，并将在2019年7月3日返回，停留三个月。该工程将使渡轮达到最新的安全、舒适和性能标准，包括乘客区的整修、驾驶室的整修、发电机和主配电板的更新、齿轮箱的大修并更换客室铝舱壁。
多年来，DSO一直与Waxholmsboraget公司和斯德哥尔摩地区保持着良好的关系，20世纪90年代初，DSO为Waxholmsboraget公司建造了5艘快速渡轮。2013年至2015年期间，DSO在Waxholm I号上进行了更广泛的工作，并升级了两艘快速渡轮Roslagen 和Skärgården号。船队中的其它渡轮也在DSO船厂进行过维修和维护。
Damen Shiprepair Oskarshamnsvarvet (DSO) has won a public tender for the contract to undertake a lifetime extension project on the passenger ferry Waxholm II. Built in 1983, the 35.5 metre ferry carries up to 350 passengers and is operated by Waxholms Ångfartygs AB (Waxholmsbolaget), the public body responsible for public transport by boat in the Greater Stockholm region. She is owned by Region Stockholm, the regional authority.
Waxholm II is scheduled to arrive at DSO on April 1st 2019 and will spend three months there before returning to service on July 3rd 2019. The works, which will bring the ferry up to the latest standards of safety, comfort and performance, will include the refurbishment of the passenger areas, the refit of the wheelhouse, the renewal of the generator and main switchboard, a major overhaul of the gearboxes and the renewal of the aluminium bulkheads on the saloon deck. With such a wide variety of activities going on at the same time, managing the many trades working across all the decks will require precise scheduling.
DSO has had a good relationship with Waxholmsbolaget and Region Stockholm over the years, and between 2013 and 2015 performed even more extensive works on Waxholm I, a sister ship to Waxholm II, and upgraded the two fast ferries Roslagen and Skärgården. Other ferries from the 25-vessel fleet of Waxholmsbolaget have also used the yard for repairs and maintenance and, in the early 1990s, DSO built five fast ferries for the same client.
Since that period, contract awards based on personal relationships have had to give way to transparent public tendering, a change that DSO welcomes, and the yard was pleased to win this latest tender by both meeting the challenging terms of the contract and offering the most competitive price.
“The three-month deadline will be tight,” says Flip van der Waal, managing director of DSO. “We have some serious challenges ahead of us regarding both the timescale and the budget, but we are confident that, with detailed planning before the Waxholm II arrives at the yard and first-class project management while she is here, we will deliver a rejuvenated vessel that will serve her passengers and crew well for many years to come.”
