Offshore waste compactors

Why compact waste?

With a compaction ratio of 10:1, our compactors can reduce the volume of galley and accommodation waste by as much as 90%.

This means a significant reduction in container movements to return waste to shore, which in turn represents a huge saving in deck crew time, container hire charges & shipping costs.

  • Fewer container movements (lower risk & cost)
  • Smaller deck space requirements (fewer containers required)
  • Less environmental hazard (waste completely enclosed)
  • Lower biological hazard (powerful disinfectant spray)
  • Lower energy use & fewer CO2 emissions

Why our waste compactors?

We have been providing its unique design of heavy-duty, fully pneumatic, waste compactors to leading offshore operators, drilling companies and specialist support vessel operators for over 30 years.  Our compactors are designed specifically for the North Sea and similar hostile operating environments and have an unsurpassed record for safe, efficient and reliable operation.  This translates directly into significant cost savings & operational benefits for customers & users.

  • Safe: comprehensive safety features, including safety inter-locks on the controls & a “fail safe” default on all operations, means our compactors are extremely safe to use.
  • Efficient: a large capacity & high compaction ratio means that less operator, deck crew & crane time is spent changing waste bags than is the case with smaller machines.
  • Reliable: an entirely pneumatic operating system, rigorous maintenance & careful pre-delivery testing means high reliability.
  • Productive: simple controls, fully enclosed operation & a short cycle time means that a large volume of waste can be disposed of in less than a minute & the compactor left to complete its cycle unattended.
  • Convenient: designed, tested & certified to be handled as an offshore container by means of a permanently-attached four-point lifting set.  Robust construction means they can withstand a considerable amount of rough handling.
  • Zero maintenance: no maintenance whilst in-service (hydraulic machines often require daily checks on fluid levels and filters).  We provide an annual maintenance change-out on rental contracts.
  • Compact & robust: a small footprint (1.8m x 1.7m) means a minimal deck space requirement & robust fabrication means there are few constraints on where they can be located.

Safety features

  • Operator positioned to side of machine with clear view across the front/working area.
  • Operator must have both hands on the controls to close door.
  • Warning horn sounds when door about to close.
  • Door closes under reduced pressure ("soft close").
  • Door can not be opened during compaction cycle.
  • If door open, will not drop if air disconnected from machine or air supply fails.
  • Compactor will only operate if the skip is in its correct position & door closed.
  • Operator must have both hands on the controls to operate skip in/out trolley.
  • Warning horn sounds when skip trolley about to move out of compactor.
  • Two Emergency Stop buttons fitted & halt the machine in its current operation.
  • Safety interlocks fully automatic & cannot be over-ridden by the operator.
  • Cannot be operated with someone inside a safety cage (as is the case with other machines).

On-going investment

We are continually striving to further improve the durability and reliability of our compactors in accordance with the principle of continuous improvement (Kaizen).  For example, by sourcing more robust components and incorporating incremental improvements as units pass through our workshops for maintenance.

We are several years into a rental fleet renewal programme with our new units designed, manufactured & certified to DNV GL Standard for Certification 2.7-1 "Offshore Containers" (June 2013) & EN 12079:2006 "Offshore Containers and associated lifting sets" (April 2006).

This means our units are robust enough to withstand being hit be other containers when being lifting to/off supply boats in rough weather.
