Offshore Ship Designers (OSD) has designed a powerful, low-emission compact e-tug to further augment its Azistern series of vessels. Among other roles, the vessel is equipped to deliver harbor assistance. OSD managing director Michiel Wijsmuller said, “The Azistern-e has the typical low resistance stable hull and all-round visibility that is associated with all Azistern designs. The hybrid power of the 22 m LOA / 50 BP Azistern-e is generated by two 970kW variable speed gensets and is supported by two 400kWh lithium battery packs.

OSD-IMT, the U.K. division of Offshore Ship Designers (OSD), announced it has developed a range of new designs of offshore windfarm service operation vessels (SOVs). The 1,350 dwt IMT972 SOV is powered by two Steerprop SP25 or equal 1900 kWe fixed pitch azimuth propulsion units. There is also an option for fitting two 2.5 MW Voith Turbo main thrusters. Frequency-controlled electric motor-driven CPP thruster units are fitted forward, comprising two tunnel-type bow thrusters and one retractable bow thruster for station-keeping and high-dynamic performance under maneuvering or DP conditions.

Offshore Ship Designers has been contracted to develop the design of a low-emission diesel-electric harbour tug for IJmuiden-based Iskes Towage & Salvage. The 32-metre loa tug will have a bollard pull of 70 tonnes and will be powered by three diesel gensets driving electric motors mounted over azimuthing propellers aft and a Voith in-line thruster forward. The Azistern 3270 tug is a further development of the low-emission Azistern series developed by OSD. It is expected to reduce emissions by 30 per cent compared to conventional, similar-sized harbour tugs now in service.

IJmuiden-based Offshore Ship Designers is to design a new compact but powerful AHT offshore support vessel for Netherlands-based Neptune Marine Service BV. The order follows a recent contract for the design of two Azistern24/56 tugs for Singapore-based Pacific Offshore Engineering and Trading Pte. The key to both designs is that although the vessels will have the capabilities of much larger tugs and offshore support vessels, their smaller size reduces both capital outlay and on-going operational costs.

IJmuiden-based Offshore Ship Designers (OSD) has opened a design office in Singapore. The office will provide a local liaison point for customers building ships in Asia which were designed in the Dutch and UK offices of OSD, and also provide a local solution for design projects for companies based in Singapore. “We already have a successful design and newbuilding supervision office in Shanghai,” said Michiel Wijsmuller, managing director of OSD. “But as Singapore is rapidly strengthening as a hub for offshore activities, it is important for us to have a company there.

Design teams in IJmuiden, Montrose, Escrick, Bideford and Shanghai will now all operate under the IJmuiden-based Offshore Ship Designers (OSD) name and will work more closely together. The office in Bideford is new and will focus on cargo ships, patrol vessels, dredgers and mega yachts. Michiel Wijsmuller, managing director of OSD, said, "We are not just rebranding, we have integrated a loose group into a strong company. WorldWise Marine and IMT are now an integrated design company with solid engineering capacity but above all, a strong independent presence in all the key markets.

WorldWise Marine, a partner in the Offshore Ship Designers group, has launched a new design for a near-zero emission hydrogen powered tug. Michiel Wijsmuller, managing director of Offshore Ship Designers, said, "This new harbor tug will be able to remain on standby, and mobilize/demobilize with zero emissions, and will save up to 98 percent of SOx, NOx and particulate matter and 30 percent of CO2 emissions in total compared to a conventional harbour tug over the whole employment cycle.
