PD ports contracted CL Prosser who asked Sarens to remove two redundant overhead gantry cranes within a warehouse in Teesport, The UK.

The challenge was to remove the gantries without modifying the warehouse structure and allowing site operations to continue at the opposite end of the warehouse. The overhead gantry cranes had to be lifted from elevated rails 15m above ground level and placed on ground to allow the demolition.

Our crew decided to use the following equipment:

  • 20 x K24 SPMT Axles
  • 2 x PPUs
  • 4 x Sarlift Gantry Towers complete with 10m long lifting beam
  • 1 x 400T Mobile Crane
  • 1 x 500T Mobile Crane
  • 100T Capacity Mobile Crane
  • BS220 Bracing Steelwork
  • S273 Spreader Beam + Tackle
  • MEWP and Telehandler

The two gantry cranes weighed 122T each and measured 30.7x12x7.8m.

Sarens engineers worked out a customised solution for the client. The trolley and the cab was positioned on the overhead gantry crane as per Sarens’ specifications and parked in their pick-up position.

A 100T mobile crane assembled the SPMTs and Sarlift gantry within the warehouse adjacent to the overhead gantry crane before driving it into position. The overhead gantry crane was lifted 800mm using the Sarlift Gantry until the underside of the girders were above the rails. The SPMTs were then used in carousel mode to rotate the overhead gentry so that it could pass between the rails and lowered. Once lowered the crane was tandem lifted onto the ground using a 400T and 500T mobile crane.

The customised solution by Sarens provided considerable cost savings and ensured that the operation was completed safely:

Cost reduction was achieved due to:

  • No requirement to remove roof sections from warehouse.
  • No strengthening work required as supports were provided to the Overhead Gantry Crane.
  • Minimal disruption to port operations.

Safety achieved by:

  • Avoiding working at a height.
  • Reduction in project man hours.
  • Work undertaken within warehouse so reduced exposure to the elements.

Singapore-based dry bulk owner Berge Bulk announced that it had signed agreements with Anemoi Marine Technologies Ltd – a global leader in wind-assisted propulsion for commercial vessels – to supply and fit two vessels in their dry bulk fleet with Anemoi Rotor Sails.

The first vessel, Berge Neblina, a 388k DWT Valemax ore carrier built in 2012, was made ‘wind-ready’ earlier this year. The structural integration required prior to installing the technology was carried out during a scheduled dry dock. Four of Anemoi’s large folding deployment Rotor Sails will be installed to improve vessel performance. Folding Rotor Sails can be lowered from the vertical to mitigate the impact on air draught and cargo handling operations.

This flexible “wind-ready” approach has been taken to align with vessel availability and Anemoi’s production slots. The same approach has been taken with the second vessel, Berge Mulhacen, a 2017-built 210k DWT Newcastlemax bulk carrier, which will also receive four folding Rotor Sails. Plan approval has been obtained for both ships from DNV.

Paolo Tonon, Technical Director at Berge Bulk, said: “We’re committed to continuous innovation and exploring cleaner, greener energy sources. Wind propulsion is an option we have explored previously in other formats, and we firmly believe it can help achieve our decarbonisation commitments. The partnership with Anemoi commenced with in-depth engineering simulations to find the best possible technical and commercial solution. Therefore, we are pleased to be rolling out their Rotor Sail technology on our vessels.”

Berge Bulk leads the dry bulk industry with efficient ship design and operations. It is committed to developing and deploying commercially viable deep-sea zero-emission vessels by 2030.

Commenting on the agreement, Kim Diederichsen, CEO of Anemoi Marine Technologies, said: “I’m delighted to be announcing this partnership with Berge Bulk. It is a further confirmation that forward-thinking shipowners are turning to wind-assisted propulsion to help them achieve their environmental objectives – and it proves, once again, that Rotor Sails are a realistic and workable solution that results in significant carbon savings.”

Rotor Sails are large mechanical sails that harness the renewable power of the wind to reduce emissions and fuel consumption on commercial ships when driven to spin. Anemoi predicts that the four-rotor system will save Berge Bulk 1,200 to 1,500 metric tonnes of fuel per vessel each year.

Leading renewable energy company Drax Group and Japanese shipping company MOL Drybulk Ltd. are working together to reduce the emissions and fuel costs associated with shipping biomass by deploying wind power technology on its vessels.

The companies plan to facilitate the development of wind-powered vessels to transport bulk cargoes of Drax’s wood pellets to its customers in Japan, where the biomass is used to generate reliable, renewable energy, which displaces fossil fuels.

The newly built vessels will be fitted with MOL’s Wind Challenger hard sail technology, with the first ship expected to be on the water as soon as 2025.

The initiative is part of Drax’s plans to further reduce supply chain emissions in line with its world-leading ambition to be a carbon negative company by 2030, by using bioenergy with carbon capture and storage.

Drax Group Chief Executive Will Gardiner said: “MOL Drybulk’s hard sail technology has the potential to transform the maritime industry, cutting emissions and fuel costs and supporting global efforts to address the climate crisis.”

He added, “This partnership to advance this crucial new technology will support Drax’s commitment to reduce its own supply chain emissions and could also deliver far-reaching benefits across a number of different sectors that rely on ships to carry goods to customers around the world.”

Under the Memorandum of Understanding, the two companies will study the feasibility of deploying a first and second generation Environmentally Friendly Bulk Carrier to carry Drax’s biomass.

The first EFBC will use MOL’s automated telescopic hard sail technology – Wind Challenger, and will evaluate the application of other technologies including rotor sails.

The second EFBC aims to at least halve emissions with new vessel designs that use multiple Wind Challenger sails, other low-carbon technologies in development and the use of alternative fuels such as ammonia, liquefied natural gas and synthetic fuels.

Kazuhiko Kikuchi, President and Representative Director of MOL Drybulk said: “MOL has been working with our partners to develop the Wind Challenger technology for over a decade, and it’s great to see this become a reality.”

He continued, “We are extremely excited to work together with an innovative company such as Drax. This partnership will help us have a positive impact on how wood pellets and other cargoes are transported across the world.”

MOL Drybulk’s work will include developing the technologies that will be used and liaising with the shipyard where the vessel will be built and fitted with the hard sail technology. Drax will work with the ports and terminals in the supply chain on the operational feasibility studies.

The MoU with MOL Drybulk follows Drax’s previous work with the Smart Green Shipping Alliance to look at the potential of fitting innovative sail technology on ships transporting biomass from the US to the UK.
