Non-Constituency MP Dennis Tan wants ships to be stopped from cutting across the narrow Singapore Strait to keep the waterway safe.
He also wants it to be made compulsory for all vesselsto install and switch on their Automatic Identification System (AIS), which provides such information as a ship's location to monitoring stations and other vessels in the area.
Use of Medisave
Mr Zainal Sapari (Pasir Ris-Punggol GRC) and Mr Louis Ng (Nee Soon GRC) said people with niche, high-cost medical needs should be allowed to use Medisave for outpatient treatment.
This could involve treatment for auto-immune diseases, or dental treatments for children with special needs as they require anaesthesia, they added.
S. Korean silver towns
Workers' Party Non-Constituency MP Leon Perera suggested that Singapore look into senior residences, such as Silver Towns in South Korea, which combine "high-rise, high-density living" with facilities that seniors may need.
A pilot project could be used to test demand, he said.
Shared 'green' time
Mr Png Eng Huat (Hougang) called for shared "green" time at signalised junctions - where vehicles are allowed to turn at the same time as the "green man" signal for pedestrians is displayed - to be done away with.
He said such a move would be safer for pedestrians.
Mr Seah Kian Peng (Marine Parade GRC) called for more to be done to promote micro-volunteering.
This involves tasks being completed by volunteers in small increments of time, at their own pace.
It can help bolster the core group of volunteers during peak times and may also lead to a longer-term commitment, he added.
