Our fleet

Fleet

A modern fleet of double hull vessels, specially equipped in accordance with the latest technical standards for the dedicated transport of liquid sulphur.

Our own vessels: optimal deployment options and technical equipment Zwaans has five dedicated liquid sulphur transport vessels with cargo capacities ranging from 1500 to 2400 tons. The following characteristics make all these vessels unique:

  • Double hulls
  • Cargo heating system and optimal insulation, making it possible to transport and deliver at the right temperature
  • Cylinder-shaped tanks and deep-well pumps to minimise residual cargo
  • Movable or adaptable wheelhouse to an overall vessel height of 4.5 m.

Quality and safety All vessels undergo a strict and comprehensive internal audit twice annually. A checklist of more than 110 items relating to quality, safety, technical aspects, as well as crew and legal requirements guarantee the highest possible degree of reliability and service. Our ISO 9001:2008 quality assurance system applies unconditionally to the office work and activities on board all vessels. In addition to the internal on board and office audits, we carry out numerous daily, weekly and/or monthly (technical) audits and checks. Lloyd’s Register Quality Assurance conducts an audit twice annually, as well as a periodical recertification procedure once every three years.

Together with the annual European Barge Inspection Scheme (EBIS) audit, carried out by the joint oil and petrochemical companies/customers on board each vessel, the extensive system of procedures, instructions, checks and audits at Zwaans, applicable in the offices and on board the vessels, ensure a high level of safety and quality, which is essential in a sector like the inland barging sector.
