It is generally agreed that mangroves are particularly sensitive to oil and that they are priority areas for protection. The main protection options are:
  • Mechanical recovery offshore from the mangroves;
  • Dispersal (using oil spill dispersants) offshore; and
  • Booming of mangrove shorelines and inlets.
Oil-containing booms surrounded the inlets to Chek Jawa...


Speed boats shuttle between Changi Point Ferry Terminal and the booms...


The NParks officers knew the area well.
They each led a team to the affected areas...

If oil enters mangroves, the main clean-up options are:
  • Booming and skimming of oil on the water surface in mangrove creeks;
  • Pumping of bulk oil from the sediment surface, depressions and channels;
  • Water flushing of free oil from sediment surface and mangroves, into areas where it may be collected; and
  • Use of absorbent materials, with subsequent collection and disposal.

The workers also had to clear up the leftovers from yesterday's clean-up...


A sticky brown residue remains after the chemical dispersant spray dried up...

Bagging the trash in more resistant sacks to prevent leakage...


Some moments of frustration as a miscommunication occurred...

There were thousands of leaves and twigs along the shores.
All these had to be swept up and cleared...


Taking a much-needed break at half-time...
