HollandMT supplies 100th gate valve !

With the recent delivery of 16 gate-valves for a newly built trailing suction hopper dredger for WSV (Wasserstraßen- und Schifffahrtsverwaltung) in Hamburg, the mile-stone of supply of the 100th  gate-valve has been reached!

Since 2009 HollandMT has designed and supplied rubber ring gate-valves for various slurry pumping applications in the dredging industry. The size of the gate-valve range from 200 to 1400 mm pipe-line diameter, pressure rating up to 40 bar.

Main characteristics of HollandMT gate-valves are:

  • Robust design: the gate valves are designed to cope with highly abrasive slurries and open/close smoothly in severe operational environments.
  • A polished knife-gate, fabricated of stainless steel.
  • Reinforced rubber ring seals (with vulcanized steel rings) for perfect sealing. The rubber seal provides an efficient and free passage of slurry mixture in the pipeline when the gate is open.
  • Equipped open/close sensors, or optional continuous knife-gate position indication.
  • At request, special dimensional requirements or modifications can be incorporated in the gate-valve design.
  • Proven performance and built to last.
  • Competitive pricing.

The gate-valves are constructed by HollandMT’s exclusive fabrication partner in Changshu China.

HollandMT receives new order for 2 set of TSHD equipment

In June, Barkmeijer shipyard awarded the contract to HollandMT for design & supply of dredging systems for two new 3,000 cubic metre trailing suction hopper dredgers for marine aggregate dredging.

For each vessel, the scope of dredging equipment includes a state-of-the art 700 mm dragarm & gantry system with submerged dredge pump enabling a maximum dredging depth of -60 m. Besides this HollandMT will also provide all dredge-pipelines, gate-valves and design integration of the dredging equipment into the vessel.

The two dredgers will be built for Hanson Aggregates in the UK, a division of the Heidelberg cement group. Delivery of these new aggregate dredgers is the first step in a strategic replacement programme for Hanson’s existing fleet of eight dredgers which deliver marine aggregates into a network of wharves in both the UK and continental Europe.

The new dredgers which will enter service in 2019 and will be equivalent in size to Hanson’s existing A-Class vessels, carrying up to 5,500 tonnes of sand and gravel. The new ships, which will provide major improvements in fuel consumption, reliability and CO2 emissions. The vessels will be built at Barkmeijer’s yard at Stroobos in the Netherlands.
