Singapore’s Covid-19 "circuit breaker" has taken its toll on Kim Heng Offshore & Marine, which suffered a 46% slump in revenue.

The offshore vessel owner reported revenue for the first six months of SGD 17.7m ($12.9m), down from SGD 32.7m in the same period last year.

This was partly offset by a nearly 50% decline in costs to SGD 13m.
